'''''Paper Mario: The Thousand-Year Door''''' is a [[Nintendo Switch]] [[Reissue|remake]] of the 2004 [[Nintendo GameCube]] game of [[Paper Mario: The Thousand-Year Door|the same name]], and the first remake in the [[Paper Mario (series)|''Paper Mario'']] series. It was first announced during the September 2023 Nintendo Direct,<ref name=Direct>Nintendo of America (September 14, 2023). [https://www.youtube.com/watch?v=8Ume5pSIcKE Nintendo Direct 9.14.2023 - Nintendo Switch]. ''YouTube''. Retrieved September 14, 2023.</ref> and released worldwide on May 23, 2024.

The title features visually enhanced and updated graphics along with new gameplay features. However, it remains faithful to the style of the original game: the characters still use their designs from the original release (for example, [[Princess Peach]] keeps her pre-''[[Mario Party 4]]'' dress design), rather than the updated designs used in the following ''[[Paper Mario (series)|Paper Mario]]'' games. Many voice clips from the original game are also reused, despite voice actor changes since the original game's release, including [[Charles Martinet]], [[Jen Taylor]], and [[Scott Burns]], former voice actors of [[Mario]], [[Princess Peach|Peach]], and [[Bowser]] respectively.
==Changes from the original game==
===New content===
;General
*Like in ''[[Paper Mario: Color Splash]]'' and ''[[Paper Mario: The Origami King]]'', a concept art gallery, the [[Art Gallery]], is available. It can be viewed from the menu, with more pieces unlocking throughout the game. The gallery includes concept art from the original game and specific to the remake. Art galleries are sorted by the story's chapters' locations and are unlocked after collecting every Star Piece from that chapter's locations and taking the chapter's Crystal Star to the Thousand-Year Door.
*An in-game music player, the [[Paper Mario: The Thousand-Year Door (Nintendo Switch) sound test|Sound Gallery]], is added to the menu. Music tracks are sorted by the story's chapters' locations in which they play and are unlocked after collecting every Shine Sprite for that chapter and taking the chapter's Crystal Star to the Thousand-Year Door.
**Equipping the Nostalgic Tunes badge allows the player to listen to the GameCube versions of the tracks in the Sound Gallery as they are unlocked. While the badge is equipped, tracks exclusive to the remake are disabled. 
*A Notes tab has been added to the menu. This lists active Trouble Center requests and any of [[Merluvlee]]'s predictions that are still relevant.
*A few new emails have been added, such as one from Professor Frankly informing Mario about the [[First Attack]] badge or one from the [[Toad Bros. Bazaar]] informing Mario when the [[Contact Lens]] have been restocked.
*A list of controls for the player's current controller can be found in the menu.
*A new music arrangement, new music tracks and sound effects were [[Paper Mario: The Thousand-Year Door (Nintendo Switch)#Audio changes|added]].
;Characters
*A Purple [[Toad (species)|Toad]] called the [[Battle Master]] can be found around the world. When talked to, he allows Mario to practice his attacks, in a similar fashion to the [[Action Command Dojo]] and [[Battle Lab]] from previous games. During his battles, Mario fights cardboard Goombas called [[Goomboard]]s.
*A Little Mouser named [[Ian Foomus]] appears in the Trouble Center, offering advice to help with different Troubles.
;Glitz Pit
*There is an Exhibition Match option and an option to read the rules when reserving a match.
**Exhibition Matches allow Mario to select and fight any Glitz Pit team that he is currently ranked above (whenever or not he has fought them previously), and these battles do not have any battle conditions, nor do they affect Mario's ranking.
**As a result, the player can easily obtain Tattle entries for enemies exclusive to the Glitz Pit if they failed to do so earlier.
**[[Wings of Night]] and [[The Destructors]] can only be fought through Exhibition Matches.
**After Mario's rank is reset after clearing Chapter 3, he must rank up to access Exhibition Matches again. However, Prince Mush can be fought regardless of rank.
;New bosses
*Two new bosses have been added:
**[[Prince Mush]] can be challenged at the Glitz Pit. To unlock him, the player must complete Jolene's Trouble, "[[Help wanted!]]", and then wait some time to receive an email from her talking about new Exhibition Matches and that Mush is training. After waiting some more time, the player will receive another email, this time from Prince Mush himself, issuing a challenge. By heading back to the Glitz Pit and selecting Exhibition Match in any league, the player can challenge him to a fight. Mario will receive [[Prince Mush's Belt]] if he defeats him.
**[[Whacka]] can be found in the [[Pit of 100 Trials (Paper Mario: The Thousand-Year Door)|Pit of 100 Trials]] and can be defeated to receive the [[Gold Whacka Bump]]. For him to appear, the player needs to have completed the entire Pit of 100 Trials by defeating Bonetail at floor 100 and hit Whacka in Keelhaul Key enough times to make him stop spawning there (he will exclaim "Whack-a-woooooooooooo..." when he disappears for the last time). After waiting around 30 minutes of in-game time, the player must return to Rogueport to receive an email called "RDM Extra Issue," which says a mystical creature has been seen deep in the pit. Whacka will appear at floor 100 after this email, and whacking him there will trigger his boss fight. Returning to the Pit and fighting Whacka subsequent times yields a regular Whacka Bump, meaning the item can now be obtained infinitely, unlike the limited amount in the original.
;Recipes
*The [[Hottest Dog]] [[recipe]] has been added and can be made by mixing a [[Hot Dog (item)|Hot Dog]] with [[Hot Sauce]]. This is in reference to the [[Businessman]]'s Trouble. In the original Japanese text, he discussed combining his Hot Sauce with [[Mr. Hoggle]]'s Hot Dogs, but this resulted in a [[Mistake]] if attempted in the original game. In the original English localization, he referred to combining a "Fat Dog" (a nonexistent item) with Hot Sauce to create a "Tongue-Blistering Fat Dog", which the remake respectively changes to "Hot Dog" and "Hottest Dog" to allude to the new recipe.
;Pit of 100 Trials
*Upon completion of the Pit of 100 Trials at least once, a [[Mover]] outside the entrance provides fast travel to the 50th floor for 300 coins.
;Tattles
*There are ten more [[List of tattles in Paper Mario: The Thousand-Year Door (Nintendo Switch)|Tattle Log]] entries compared to the original game, bringing the total to 134. Amongst these include the [[Goomboard]], the Fuzzy Horde in Shhwonk Fortress, the X-Naut horde in Lord Crump's second fight, and the two new bosses, Whacka and Prince Mush.
**The second fights against Bowser, Doopliss, Beldam, and Marilyn and the second phase of the Shadow Queen now have separate Tattle Log entries. As a result, if they were Tattled in their first battles, their HP is not immediately shown in their rematches until they are Tattled again.
;Creepy Steeple
*[[The Creepy Steeple Boo]] can be found in the storeroom after freeing the Boos trapped in the box under Creepy Steeple, where he will quiz Mario on various parts of the story. There are six quizzes, with the last quiz having 15 questions in total and only being available during the post-game.
;Trophies
*Three trophy items have been added as rewards for Journal completion:
**The [[Cooking Trophy]] for obtaining all [[recipe]]s
**The [[Badge Trophy]] for obtaining all [[badge]]s. 
**The [[Tattle Trophy]] for completing the [[Paper Mario: The Thousand-Year Door bestiary|Tattle Log]].
;Badges
*The [[Nostalgic Tunes]] badge, resembling a [[Nintendo GameCube]], can be bought from the [[Lovely Howz of Badges]] for one coin. Equipping it will revert the music to the original soundtrack. The game still plays tracks exclusive to the remake, however.
*Mario is awarded with a [[Gold Medal (Paper Mario: The Thousand-Year Door)|Gold Medal]] for obtaining all three trophies. It has the effect of visually turning him gold, and the effect will stack with the [[L Emblem]] and [[W Emblem]].

===Gameplay changes===
;Menus and controls
*The player's play time for their save file can no longer be seen in the game's menu.
*The player can no longer scroll through their list of items and badges using the {{button|Switch|L}} and {{button|Switch|R}} buttons, as they are used to scroll through the menu screens instead.
*Conversations can no longer be sped up, nor can the player view previous messages in the conversation. Text can only be sped up if an entire conversation has been seen before being played a second time.
*The [[Mailbox SP]] mail system has been reworked to function similarly to the notifications system from ''[[Paper Mario: The Origami King]]'', where alerts no longer affect the player's ability to navigate in-game. Pressing {{button|switch|plus}} while the notification is on-screen immediately opens the email.
*Like ''Paper Mario: The Origami King'', the last saved point can be accessed from the [[Game Over]] screen and the current scene can also be played again, with any scene in which the player was last in capable of being played again. In some instances this option to play from the last scene loads a save from before the last [[Save Block]] was hit. In the original, this was limited to certain situations.
*Like with collectibles in ''Paper Mario: The Origami King'', the map screen tracks the percentage of collected Star Pieces and Shine Sprites from each location.
*When leveling up, the player has to press a direction with the {{button|switch|leftstick}} to select an option rather than HP being the default.
*If the player is wearing an FP Plus or HP Plus, increasing their FP or HP respectively, when leveling up, the higher numbers for increasing FP or HP will take into account the badges worn.
*All partners are fully healed upon leveling up rather than only the active one.
*The Nintendo Switch system keyboard is used when prompted to name the Yoshi Kid instead of an in-game one. However, all other text input prompts, such as the ones for inputing Doopliss' name and the access code in X-Naut Fortress, still use an in-game keyboard.
;Field
*Mario can swing his Hammer forwards and backwards like in entries since ''Paper Mario: Sticker Star''. In the original game, he could only swing his Hammer sideways.
*Bushes can no longer be interacted with when near them, but they can be crumpled with the Hammer for the same effect, as with ''Paper Mario: Color Splash''. Incidentally, Bowser can still interact with bushes in the same manner as in the original game.
*Both Mario's partners and NPCs will react when hit with Mario's Hammer. NPCs will also react when Bowser breathes fire on them during his intermissions.
*Like in later entries, there is safeguarding on the edges of areas to prevent the player from accidentally falling off. If Mario approaches an edge, he will stop moving forward and teeter on the edge to give the player the ability to move back onto stable ground, only falling off if the player continues to move forward after the animation begins.
*{{button|Switch|L}} and {{button|Switch|ZL}} have new functions. Pressing {{button|Switch|L}} now opens up the Partner Ring, which Mario can use to switch between partners, while {{button|Switch|ZL}} makes a partner provide [[List of Partner Hints in Paper Mario: The Thousand-Year Door|Partner Hints]] (whether or not they are active) to direct the player to their objective. The partner that gives the player the hint is usually Goombella, but it may vary depending on the situation or the area. In the original game, {{button|GCN|L}} was only used to navigate menus.
*The Paper Plane mode stays at a fixed distance from the ground until it has transcended the horizontal width of the activation panel.
*The player can use the Hammer to locate flippable panels on the ground containing Star Pieces, although the Hammer still cannot flip them. In the original game, this is not possible with any Hammer, with the only way to locate panels being to use Spin Jumps.
*When using [[Koops]]'s partner field ability, a green circle marker with an arrow appears where Mario launched Koops, with the arrow indicating the direction Koops's shell will launch.
*Breaking large blocks using the [[Super Hammer]] or the [[Ultra Hammer]] requires Mario to charge beyond the minimal amount.
*When riding on the Yoshi Kid, Mario has momentum-based physics that apply when riding off edges, making traveling down them slower than in the original game. The Yoshi Kid's flutter jump is also more continuative from walking and thus slightly different from the original.
*The player can open doors and talk to NPCs while riding on the Yoshi Kid, although Mario still dismounts off the Yoshi Kid to do either action.
*If Mario is riding the Yoshi Kid as he falls on a jump pad, he will stay on the Yoshi Kid after bouncing off, unlike in the original game.
*There is a prompt to check interactable elements in the scenery or to talk to characters, hinting at what the player can do with them.
*Enemies on the field have a shorter range of sight to spot and chase after Mario than in the original game.
;Warp Pipes
*They are entered by pressing {{button|Switch|A}}, with a prompt appearing above one to tell the player to do so. In the original game, entering Warp Pipes required tilting down on the {{button|gcn|stick}} and no hint appeared to do as such.
*They have new hitboxes.
*When emerging from one, Mario automatically jumps out and forward.
*There is a new Warp Pipe room, similar to the "One World, One Pipe" room in [[Musée Champignon]] from ''Paper Mario: The Origami King'', replacing the original pair of Warp Pipe rooms across [[Rogueport Underground]]. When entering this room after taking a Crystal Star to the Thousand-Year Door, the Magical Map is held up in a similar fashion, unlocking a pipe leading to a locale for that Crystal Star's chapter. There are seven pipe slots instead of four, with a pipe leading from this room to Rogueport Plaza also able to be opened.The door leading to the room on the right side is also now hidden and requires Flurrie to reveal it.
**Pipes 1, 2, and 6 lead to the second area of Petalburg, the outside of The Great Tree, and the fountain in Poshley Heights in the same spots as in the original game.
**Pipe 3 leads to Glitzville, southeast of the juice shop.
**Pipe 4 leads to the second area of Twilight Town.
**Pipe 5 leads to the campsite of Keelhaul Key, instead of the jungle like in the original game.
**Pipe 7 leads to the second area of Fahr Outpost.
*Several new ones were added:
**One was added behind the Last Stand P badge in [[Hooktail Castle]] that takes the player back up without having to backtrack.
**One was added from [[Creepy Steeple]]'s basement to the right-most house of [[Twilight Town]] to cut backtracking in Chapter 4. It can be unlocked by heading right from the room with the [[Parrot (character)|parrot]].
**One was added in the [[Palace of Shadow]] leading from the Depths room before the Shadow Queen south of the save block back to the entrance of the palace at the bottom middle of the entrance room to cut backtracking. It appears after dying to the boss or clearing the game. If it does not appear, the player must restart the game and load the save. Mario's active partner will comment on the new pipe's appearance in the room.
;Save and Recovery Blocks
*Just like ''[[Paper Mario: Color Splash]]'' onward, when hitting a [[Save Block]], the game no longer asks whether to save or not.
**This also applies when the game transitions to each character segment and when the game is completed.
*New [[Save Block]]s have been added or relocated:
**The one near the pedestal of [[The Thousand-Year Door]] is moved to the entrance of the [[Pit of 100 Trials (Paper Mario: The Thousand-Year Door)|Pit of 100 Trials]].
**The one in the first area of Boggly Woods is moved to the second area, allowing the player to save before the Three Shadows fight.
**One appears in the third area of [[Twilight Trail]], past the fallen tree.
**The Save Block in Creepy Steeple's main room has been moved to the room with the spiral stairway.
**One appears outside the derelict ship that houses a Black Chest in Pirate's Grotto.
**One appears on Sublevel Two of the X-Naut Fortress, just east of the elevator doorway.
**One appears in the Palace of Shadow in the round room, replacing the ? Block left of the Badge Block that originally contained only one coin.
*New [[recovery block]]s have also been added:
**One appears in the third floor of Hooktail Castle and costs 10 coins to use.
**One appears at the entrance to the Pit of 100 Trials, next to the new Save Block.
**One appears in a tall chamber in the Pirate's Grotto next to the Save Block.
**One appears in the outdoor section of Riverside Station.
**One appears at the easternmost part the Fire Bar section of the Palace of Shadow, costing 20 coins to use.
*The Save Block and recovery block in the Palace of Shadow's courtyard have switched spots, with the recovery block now on the west side of the canal and the Save Block now to the east of the canal.
*The cost to use the recovery block in the factory of X-Naut Fortress has increased from 10 coins to 20, matching the cost of the one at the front entrance.
;Trouble Center
*The [[Newsletter...]] Trouble is only available after clearing Chapter 7 instead of after Chapter 4.
*For the [[Try to find me!]] Trouble, [[Koopook]] is found below the third floor in [[Hooktail Castle]] instead of on the fifth floor.
*For the [[Important thing!]] Trouble, Frankie's Wedding Ring is on top of the wall beside Frankly's house (where it is in the Japanese GameCube version) instead of on the ground near Garf's house.
*The amount of coins rewarded for several Troubles have been changed:
**All Troubles that originally rewarded Mario with twenty coins ([[Need a key!]], [[Safe delivery...]], [[Competitor research!]], [[Find this guy!]], [[I can't speak!]], and [[Roust these cads!]]) reward him with thirty coins instead.
**After completing the [[Life Mushroom!]] Trouble, the [[Puni elder]] rewards Mario with fifty coins instead of sixty coins.
;Skippable cutscenes
*Cutscenes that have already played out before can be skipped with {{button|switch|plus}}. These scenes include:
**Zess T.'s cooking sequences after the player's first recipe.
**Resting sequences, although only if the player has previously rested at a particular spot.
**The beginning of a Glitz Pit match the player has already competed in that is not special (like a first time rematch).
**Boss cutscenes if the player had a Game Over from that fight.
**Powering up with [[Merlon]] and [[Chet Rippo]].
**The effect of a charm spell in a battle.
**Sailing the Black Skull.
**The Excess Express starting and stopping.
**Entering and leaving the Palace of Shadow through the Thousand-Year Door.
**Most of the Game Over screen.
====By location====
;Rogueport
*Hitting cockroaches with Mario's hammer or jumping on them awards one coin. In the original game, they were non-interactable.
*The garbage pail in Professor Frankly's house can be interacted with from the beginning of the game.
*One-time items sold in the [[Toad Bros. Bazaar]], such as the [[Contact Lens]], always replace the [[Fright Mask]] sold at the shop until they are purchased instead of the [[Mushroom]].
*The [[Lovely Howz of Badges]] has a box at the end of the counter that stores badges sold at the shop that aren't currently on display on the counter. Mario can interact with the box to purchase these badges, but their prices are inflated compared to their display prices.
;Rogueport Underground
*[[Merluvlee]] can provide her predictions as soon as Mario first enters Rogueport Underground without requiring the player to visit [[the Thousand-Year Door]] first.
*[[Dazzle]] is found on the opposite side of the fallen pillar outside of Merluvlee's house, although he will return to his location from the original game after the player visits the Thousand-Year Door.
;Pianta Parlor
*The minigame machines have been changed from slot minigames to sliding minigames similar to the [[Spade Panel]] minigame from ''[[Super Mario Bros. 3]]''.
*The player is no longer required to beat certain high-scores from the minigames, as they now keep track of the player's own high-scores instead of the defaults.
*[[Pianta token]]s are no longer given or taken by Lahla at the Pianta Parlor.
*All but three of the Pianta token prices in the redeem shop have been changed: Refund and Super Appear costs 60 Piantas instead of 34, Power Jump and Power Smash cost 80 Piantas instead of 34, FP Plus and HP Plus cost 150 Piantas instead of 100, Multibounce costs 100 Piantas instead of 50, HP Plus P costs 160 Piantas instead of 200, Gold Bar x3 costs 600 Piantas instead of 234, Power Rush and Power Rush P cost 100 Piantas instead of 34, Hammer Throw costs 120 Piantas instead of 50, Tornado Jump and Quake Hammer cost 150 Piantas instead of 67, Jammin' Jelly and Ultra Mushroom cost 80 Piantas instead of 67, and Money Money costs 450 Piantas instead of 234.
;Petal Meadows
*The pillars meant to contain the [[Sun Stone]] and the [[Moon Stone]] and the rock-covered Warp Pipe can be interacted with as soon as Mario and Goombella arrive in the area, with Goombella notifying Mario that the pillars look like something should be placed inside of their indentations and that the rock "kind of reminds me of a pipe."
*Higher hills have replaced invisible walls in the background to prevent Mario and his partner from moving off-screen.
;Petalburg
*A red Toad who was originally positioned outside the shop is inside it and gives advice about POW Blocks on Mario's first visit.
;Path to Shhwonk Fortress
*In the first area, there is a large bush from which a Koopa Troopa emerges, initiating an ambush battle that serves as a tutorial for audience thrown items in battle and stage props falling on party members or enemies. If the player equips a badge that affects battles, either one from Dazzle or the Pretty Lucky badge found in a hidden block in the Rogueport Underground, the game will softlock after this tutorial.
*Inside the mini fortresses, the player fights the [[Bald Cleft]]s and [[Bristle]]s by using the Hammer to knock them off their pedestals instead of interacting with the pedestals. The player can still interact with the pedestals, but doing so only leads to Goombella hinting that Mario should hit the pedestals with his Hammer to fight the enemies.
*The door in the room with the Bristles can be interacted with, contrary to the original game.
;Shhwonk Fortress
*Mario receives his first email on the [[Mailbox SP]] immediately upon leaving the fortress instead of in Petalburg like in the original game. Goombella also provides the player with a tutorial on how emails work instead of a tutorial text box.
;Hooktail Castle
*The [[Dull Bones]] horde push Mario out into the previous room instead of outside the entire castle. 
*The ceiling spikes no longer kill Mario before the timer reaches 0.
;Glitzville
*The hotdog cutout standee next to the [[Hot Dog Stand]] can be interacted with for photo ops. The photo can either be zoomed in on the standee, zoomed out to include the stand, or zoomed far enough out to include the stadium entrance. While Mario puts his head in the standee, his active partner can also appear and make an animation or a pose, with a total of three per partner.
*When chasing the jumping egg by the Hot Dog Stand, the camera locks into place rather than continuing to track Mario.
;Glitz Pit
*Mario no longer goes down a rank if he loses a match unless he becomes the champion a second time and loses against [[Rawk Hawk]] in the rematch battle, where he'll then lose the champion status.
**As a result, Mario can only fight [[Wings of Night]] and [[The Destructors]] through Exhibition Matches.
*The hologram screen in the lobby functions as a menu, listing every fighter and their ranking in the Glitz Pit.
*After reserving a match, Mario can interact with the locker room doors to cause the [[Glitz Pit Security]] to immediately enter the locker room to take Mario to the match instead of the player having to wait for them to arrive like in the original game.
*The battle condition against [[The Iron Adonis Twins]] is always to use a partner skill at least once.
*The first cake gifted by [[Jolene]] no longer restores SP.
*Battle conditions are no longer given when battling [[Rawk Hawk]]. In the original game, Mario would always be given the condition of performing at least one Special Move.
;Twilight Town
*Mario and his partner can now jump and walk into the pumpkin patch.
*During the search for [[General White]] in Chapter 7, Mario must talk to either [[Mayor Dour]] or the [[Twilighter]] standing near the [[Twilight Shop]] to advance the quest-line instead of talking to the Twilighter in front of the inn like in the original game.
;Twilight Trail
*There is a large movable stone that blocks the entryway to the shed.
*When encountering Doopliss subsequent times after failing to guess his name the first time, an option is given to guess again or immediately escape.
*In the Japanese version, the in-game keyboard no longer has the option to switch between hiragana and katakana when the player is prompted to guess Doopliss' name, instead only having a katakana keyboard.
;Creepy Steeple
*The Buzzy Beetles no longer attack the player immediately on entering the second room in the well.
*The blocks controlling the position of the stairs become inactive when hit until the other block is hit.
*Mario can jump all the way down the stairs below Doopliss's room instead of having to walk down them from top to bottom.
;Keelhaul Key
*There is a switch at the top of a cliff that makes a [[Trampoline|jump pad]] appear as a shortcut for this area.
*The lost [[Wedding Ring]] produces a sparkly effect over the bush containing it, making its hiding spot more obvious.
*The Fuzzies in the third area remain present after clearing Chapter 5. In the original game, they disappeared from this area after clearing the chapter.
*The [[Flower Fuzzy]] on the ledge no longer gets stuck mid-air if it falls off the ledge.
;Pirate's Grotto
*A new ambush battle occurs when the player reaches the Bill Blaster corridor room's eastern exit after obtaining the boat transformation.
*A Toad shopkeeper with orange spots on his cap is found at the end and can also be found just outside the shore before the fight with Lord Crump.
*After completing Chapter 5, the barrels in the area where Mario rescued shipwrecked Toads respawn, allowing the player to more easily access the other areas of the Grotto instead of having to backtrack to the entrance.
;Excess Express
*The note that Beldam leaves is an inventory item called the [[Threatening Note]].
*After clearing Chapter 6, when riding on the Excess Express, the player is given the option to either stop at Riverside Station or travel directly to the destination point (Poshley Heights or Rogueport). In the original game, the player was forced to stop at Riverside Station first.
;Riverside Station
*The four turning colored platforms in the Machinery Room stop in a preset pattern. The pattern for which the player must use to cross them is as follows: yellow, green, pink, green, pink, blue.
;Poshley Heights
*After obtaining the Garnet Star, the player no longer needs to exit the Poshley Sanctum to trigger the Peach intermission. It is instead triggered after the conversation with Pennington after emerging from the Warp Pipe from the painting.
;X-Naut Fortress
*There are four [[Security Key]]s and card terminals for Sublevel Three instead of three like in the original game. A new purple Security Key replaces the blue one originally there, with the latter now appearing in the restroom of Sublevel Four.
**The [[Elite X-Naut]] battle in the restroom is an ambush battle instead of a regular battle. It must be won to obtain the blue Security Key.
;Palace of Shadow
*The camera pans over the edges of the first lake bridge, revealing items to the player.
*In the torch maze room, the torches on the left side can be lit, requiring the player to backtrack several times for the puzzle to be solved.
*The doors inside the Tower cannot be opened until the player inserts the [[Star Stone (Paper Mario: The Thousand-Year Door)|Star Stone]] into the slot at the top of the tower.
*Solving the puzzles requiring Flurrie and Bobbery in their respective rooms in the Palace of Shadow Tower reveal blue ! Blocks to make the treasure chests containing Tower Keys appear. In the original game, solving the riddles just revealed the treasure chests.
*The block the Ultra Hammer is required to smash is more obviously hidden.
;Pit of 100 Trials
*Should the player get a Game Over on any floor, they are given the option to repeat that floor rather than being forced to start from the beginning.
;Intermissions
*When Peach dances with her hologram, the player must hold the indicated buttons instead of just pressing them. {{button|switch|y}} is also a possible button that appears.
*When Peach enters Grodus's room while disguised as an X-Naut, she is no longer able to roam freely around the room and Grodus is now standing by his chair instead of in the middle of the room.
*When pausing during Bowser intermissions that involve traversing a level, the player can pause gameplay or retry the level. Selecting retry restarts the level on the next life.

===Item changes===
*The player can hold fifteen items in their inventory by default instead of ten like in the original game. The [[Strange Sack]] item still increases the item capacity to twenty, however.
*The coin limit has increased from 999 coins to 9,999 coins. In turn, Hooktail now makes a false offer to grant Mario 10,000 coins instead of 1,000, and, when the [[Money Money]] badge is equipped, the max number of coins per battle has increased from 32 to 99. In addition, if Mario gives [[Lumpy]] the maximum amount of 300 coins prior to the end of Chapter 4, he will receive the full amount of 999 coins from Lumpy after the end of Chapter 6 even if he already has coins on hand, unless he already has over 9,000 coins on hand.
*On the other hand, the pianta token limit has ''decreased'' from 99,999 to 9,999.
*[[Charlieton]] appears in [[Boggly Woods]] to sell his wares, including Mushrooms, Honey Syrups, Fire Flowers, Sleepy Sheep, POW Blocks, and Mini Mr. Minis.
*The player can use an item from the inventory or immediately use a new picked up item if picking up a new item when the inventory is full.
*Some badges' [[Lovely Howz of Badges#Sell Prices|sell prices]] have changed.
*In the [[Happy Lucky Lottery]], the top prize badges [[Lucky Day]] and [[Power Plus]] are switched.
*Item shops show the quantity of the player's consumable items and their shop points when talking to a shopkeeper.
**Multiple items can be stored/withdrawn at once.
*Some of Charlieton's [[Charlieton#Rogueport|item prices]] in Rogueport have increased.
*Some of Charlieton's items in the Pit of 100 Trials have changed. He sells Ultra Mushrooms instead of Super Mushrooms and Jammin' Jelly instead of Maple Syrup.
*Any Zess T.-made items the player obtains outside Zess T.'s kitchen, such as Trouble rewards, are added to the Recipes list regardless of whether the player has already made them or not.
*To accommodate for the addition of the Warp Pipe Room, the Shine Sprite and the FP Plus badge from the original rooms are located behind a large yellow block and a large stone block respectively at the back of the Warp Pipe Room.
*The [[Trial Stew]] can be made by cooking a [[Thunder Bolt (item)|Thunder Bolt]] with a [[Thunder Rage]] in addition to cooking a [[Couple's Cake]] with a [[Poison Mushroom]], matching the Japanese version of the original game.
====Regular items====
*The [[Life Mushroom (Paper Mario series)|Life Mushroom]] revives Mario if he loses all of his HP on the field in addition to doing so in battles.
*Sleepy Sheep was nerfed to last only 3 turns (Sleepy Stomp still retains the original 5).
*The selection of items for the [[Mystery Box (item)|Mystery Box]] was changed to Mushroom, Honey Syrup, Stopwatch, Repel Cape, Fire Flower, Shooting Star and Thunder Rage. Later chapters replace Mushroom and Honey Syrup with their upgraded forms.

**'''Glitz Pit:''' The Ice Storm item in the major league locker room is hidden inside one of the western lockers instead of behind them.

**'''Palace of Shadow:''' A Thunder Rage and a Mr. Softener, behind the platforms in both the left and right corners of the room.

====? Blocks====
*'''Riverside Station:''' In the Deck with the sunshine, a lone ? Block that was previously empty and only served to reach a hidden block was given a single coin.
*'''Palace of Shadow:''' The ? Block containing a Repel Cape is now on the ground instead of originally being in the air.
*New ? Blocks have been added.

**'''Palace of Shadow:''' A ? Block containing a Power Punch replaces the Life Mushroom in Gear Room One.

====Hidden Blocks====
*New [[List of hidden blocks in Paper Mario: The Thousand-Year Door|hidden blocks]] have been added:
**'''Pirate's Grotto:''' A second support block east of the sluice gate controls, in the area with the Save and recovery blocks; used to create a two-block bridge with another hidden block for reaching an out of reach Shine Sprite.
**'''Pirate's Grotto:''' One containing a Super Mushroom in the second lower stone platform near the [[Black Skull]]. This item becomes unobtainable after [[Cortez]] decides to help Mario and his friends fight the X-Nauts just after completing Chapter 5.
**'''Riverside Station:''' One containing a Super Mushroom in the Records Room, at the end of the middle ledge on the right.
**'''Rogueport Underground:''' Two on the top of Herb T.'s building: one containing a Power Plus P badge on the northeastern part of its roof and one containing an Ultra Mushroom on the northwestern corner of the roof.
**'''Palace of Shadow:''' Two in the courtyard, at the tower's entryway: one containing a Jammin' Jelly on the left side of the tower's base and one containing an Ultra Mushroom on the right side of the tower's base.

====Star Pieces====
*Some Star Pieces were moved:
**'''Rogueport:''' The one behind the pipe that leads to the [[Blimp|Cheep Blimp]] was moved to the right, under a panel uncovered with a Spin Jump.
**'''Creepy Steeple:''' The Star Piece in the back of the treasure room behind a hole to the north of the entrance was moved behind a barrel to the left.
**'''Excess Express:''' The panel containing the Star Piece in cabin 004 was moved to the center.

====Shine Sprites====
*Some Shine Sprites were moved:
**'''Pirate's Grotto:''' A Shine Sprite was moved since Mario can hammer directly towards the player's position. In the next room, coins were added on the boat panel.

====X-Naut Fortress crane game====
*{{button|switch|X}} and {{button|switch|Y}} operate the crane controls, instead of the GameCube original’s {{button|gcn|A}} and {{button|gcn|B}}.
*Upon returning to the X-Naut Fortress in the post-game, there are four batches of items that randomly appear in the crane game. To make the next batch appear, the player must collect every item in the current batch, leave the X-Naut Fortress, and return to it.
**The first batch contains a POW Block, Sleepy Sheep, Courage Shell, Mr. Softener, and five coins.

===Badge changes===
*The [[First Attack]] badge costs 0 BP to equip, down from 1 BP.
*The [[Hammer Throw (badge)|Hammer Throw]] badge does 2 piercing damage instead of dealing regular hammer damage. Its description was changed to match.

===Text and localization changes ===
*The game has been translated into Chinese (Simplified and Traditional), Dutch, Canadian French, Latin American Spanish, and Korean. The original game was not available in these five languages since, at the time, Nintendo of Europe did not do Dutch localizations, Nintendo of America localized games into English only (not French or Spanish), Nintendo of Hong Kong and Nintendo of Korea did not exist yet, and the game was not among the 27 GameCube titles licensed for release in South Korea. Furthermore, even if the game had been released in South Korea, GameCube games in the region were generally only available in English.<ref>{{cite|author= Dentifritz|language=en|url=scanlines16.com/en/blog-3/retro-gaming/game-cube/gamecube-korean-master-list|title=Gamecube : Korean Master-List !|publisher=Scanlines16.com|archive=https://archive.ph/kYrao|accessdate=January 5, 2024}}</ref>
*Text is vertically centered within text boxes. In the original game, text was aligned to the top of the box. Some text has also been reformatted due to the higher screen resolution allowing for more text per line.<ref name=Direct/>
*Some additional portions of dialogue incorporate icons on the right side, such as icons for Star Points and Professor Frankly.
*In the Italian version, chapters were called {{color|red|"Scena"}}, or scenes; this is changed to {{color|green|"Capitolo"}}, chapters. Additionally, the chapter numbers are written with Arabic numerals rather than Roman numerals, and chapter 4's name is changed from {{color|red|"Per chi suona la campana"}} to {{color|green|"Per chi suina la campana"}} (both translate to "For Whom the Bell Tolls", but the latter contains a pun with "suona", tolls, and "suina", swine).
*Obtaining a new item now says "You got [item]", to avoid typos such as "You got a Super Boots".
*The {{color|red|"END OF CHAPTER"}} text that displays when collecting a [[Crystal Stars|Crystal Star]] has been replaced with {{color|green|"CLEARED!"}}.
*Due to the addition of the Partner Hint system, several of Goombella's Field Tattles are rewritten to remove hints that are accessible through Partner Hints instead. For example, her tattles in [[Hooktail Castle]] no longer emphasize using Koops to overcome obstacles.
*Ages for characters are omitted from [[Mailbox SP#RDM E-Mails|RDM e-mail]] messages in the English version.
====Title screen====
*The game's logo in international regions has been redesigned to more closely resemble the Japanese logo of the original game. Conversely, the Japanese logo is primarily written in English, matching the design conventions of the series's Japanese logos from ''Super Paper Mario'' onward.
**The title screen and the shot of the boat in the ocean use a horizontal logo in international regions, similar to entries since ''Super Paper Mario''.
**By extension, the box art in international regions is based on the Japanese box art of the original game.
*New files are labeled as "{{color|green|From the beginning}}" rather than "{{color|red|New Game}}".

====Names====
*The Yoshi is referred to as Yoshi Kid, such as in the name of his theme in the in-game soundtrack. When choosing his name, however, the player is still only given eight character spaces and thus cannot name him "Yoshi Kid".
*The number "3" in the name of the [[Traveling Sisters Three]] is written out rather than written as a number.
*The separate Latin American and Castilian Spanish translations mean some characters have different names between the two versions. For example, [[Swindell]] is named Fraudio in Latin American Spanish and Serrallonga in Castilian Spanish.
*Charlieton's Castilian Spanish name, Ahmed, has been changed to "M. Baucador" (a pun on ''embaucador'', "trickster"), likely due to the negative implications behind giving a shady salesman character an Arabic name. His Italian name, Tel-arub, has also been changed to Rubicone.
*In the Castilian Spanish localization, Rawk Hawk is named "Halcomán" rather than "Hawk Hogan" (this also carries over to the new Latin American Spanish localization).
*Dupree's Castilian Spanish name has been changed from Afro to Rolfunk. His French name, Belvis, has also been changed to Zeking.
*The cannon in Fahr Outpost is named "Big Bob" rather than just the "big bomb cannon".
*Enemies originally written with abbreviations have their full names displayed at all times.
*The names of the [[Big Blooper#Paper Mario: The Thousand-Year Door|Blooper]]'s {{color|red|L. Tentacle}} and {{color|red|R. Tentacle}} have been swapped to match their positions from the viewer's perspective rather than that of the Blooper, and are now referred to in full as the {{color|green|"Left Tentacle"}} and {{color|green|"Right Tentacle"}}.
*Any Shroom-based recipe has been renamed to use {{color|green|"Mushroom"}} instead of {{color|red|"Shroom"}}.
*In the original game, items in some translations had abbreviated names due to character constraints, such as the [[Red Key (Paper Mario: The Thousand-Year Door)|Red Key]] in German, which is written as Schl. (rot) instead of Schlüssel (rot). In the remake, the full names are written out.
*In the Italian version, the name of the University of Goom is changed to accommodate its rename in ''[[Paper Mario: Sticker Star]]''.

====Grammar and style====
*In the English version:
**Most instances of excessive punctuation marks have been reduced and most heart and star icons in dialogue are no longer present.
**All instances of two hyphens and semicolons, as well as some instances of commas and colons in dialogue, have been replaced with em dashes (—).
**Every instance of {{color|red|"e-mail"}} has been changed to {{color|green|"email"}}.
**Several other words and phrases have had hyphens or commas removed or added.

====Corrections====
*Several translation errors, typos, and continuity errors from the original game have been fixed:
**Kooskoos to [[Koopa Koot]].
**Mushville and Mushroom Town to [[Toad Town]].
**Goomstar Temple to [[Crystal Palace]].
**Bubu to [[Li'l Oink]]s.
**The Spiny Eggs [[Sky-Blue Spiny|Sky-Blue Spinies]] come out of are correctly referred to as such instead of as {{color|red|"pipes".}}
**The Tattle for [[Paragloomba]] correctly states it is a stronger version of a {{color|green|Paragoomba}} instead of a {{color|red|Parakoopa.}}
**An instance of "Chomp Chomp" in the Tattle for [[Chain Chomp]] has been corrected.
**The Tattle for [[Koopa Troopa]] includes its stats information ("Max HP is 4, Attack is 2 and Defense is 1."), which was missing in the original game.
**In the North American localization of the GameCube original, the Tattle for [[Spike Top#Paper Mario: The Thousand-Year Door|Red Spike Top]] stated its Defense was 5 instead of 4 and the Tattle for [[Rawk Hawk]] stated his Attack was 3 and his Defense was 1 instead of 4 and 0 respectively. Both of these errors have been corrected in the remake's North American localization.
**Every instance of [[Yoshi Kid]] calling Mario by his actual name instead of Gonzales before the ending has been corrected.
**[[Ghost T.]]'s dialogue after completing his quest has been updated to {{color|green|"The wood paneling's so great."}} as opposed to {{color|red|"The wallpaper's so great."}}, which was likely a translation error given his cabin, like all cabins on the train, has wood paneling and not wallpaper. 
**Peach's emails have been slightly altered to better align with the actual story developments in her intermissions:
***In her first email, Peach states that the X-Nauts {{color|green|"may be aware"}} that Mario has the map rather than that they {{color|red|"are already aware"}} and she does not encourage Mario to collect the Crystal Stars, as she has already learned that Mario collected the first.
***In her third email, Peach states that the X-Nauts are seeking the Crystal Stars to claim the legendary treasure, as she had learned this from Grodus (she previously stated that she did not know what the Crystal Stars did).
***In her fourth email, Peach states that the X-Nauts plan to {{color|green|"unseal"}} the demon's spirit held behind the Thousand-Year Door rather than {{color|red|"revive"}} it.
**Lakitu's log description has {{color|red|"Spiny eggs"}} capitalized properly as {{color|green|"Spiny Eggs."}}
**Hammer Bro's log description says "vicious and relentless hammer ''lobs''" instead of "jobs."
**[[The Iron Adonis Twins]] are correctly referred to by this name in all dialogue in English. In the original game, certain instances of dialogue incorrectly refer to them by their descriptor "The Armored Harriers".
**[[The Goomba Bros.]] are consistently titled "the Meteorite Hardheads"; in the original game, they were mistakenly titled "the Hoppin' Hardheads" when first introduced.
**Little Mousers are called by this name, rather than being called Squeeks like in the original game.
**[[Gloomer]] is always referred to by his proper name instead of as "Freddy" when he is first met.
**The "[[Mailbox SP#"Special Final Issue!" section|Special Final Issue!]]" section in the final regular RDM email is included in the English localization, which had been lost in translation in the original game.
**Goombella's Tattle for the [[Parrot (character)|parrot]] in Creepy Steeple is now functional ("That's Doopliss's parrot. Seems like he's been abandoned down here... Poor little guy..."). In the original game, the text was present but unused, with Goombella instead continuing to give the Tattle for the room if the player used Tattle on the parrot.
**In the German and Spanish versions, the translation error where [[Toadette]] was incorrectly referred to using the name of [[Vanna T.]] from the first ''Paper Mario'' (which was likely due to the two characters sharing the same name in Japanese) has been corrected.
**In the original game's English localization, when the player decides whether or not to attack Grodus after he strikes Mario and his partner with lightning, Grodus's responses were erroneously switched: he said "WORM! You dare defy me?!?" if the player selected "Don't attack", and "Stop your blubbering!" if the player selected "Attack". This was corrected in the remake's English localization so that Grodus gives the appropriate responses to Mario's actions.
**The description for the [[Erase that graffiti!]] trouble now has the word "the" added to the sentence "I need someone to go to 50th floor of Pit of 100 Trials for me," making it grammatically correct.
**While other references to the first ''Paper Mario'' have been corrected, the "Chestnut King" in Luigi's stories remains as such, despite sharing his name with the [[Goomboss|Goomba King]] (or otherwise being referred to as a Goomba) in most other languages.

====Descriptions====
*The descriptions of many usable items and badges have been clarified or had false information removed.
**In the original game, the descriptions of the [[Thunder Bolt (item)|Thunder Bolt]] and [[Thunder Rage]] falsely claimed that they could stun enemies. In the remake, this was fixed and changed to say that they deal 5 damage to enemies.
**The description for the [[Shooting Star (item)|Shooting Star]] no longer says it can confuse enemies, with this being replaced with specifying how much damage it does.
**The description for the [[Earth Quake]] says it can also hit enemies on ceilings and that it does 5 damage.
**The [[Hot Sauce]]'s description specifies what effect the item has when used.
**The [[Cake Mix]]'s description says that it can be consumed to restore FP.
**The [[Icicle Pop]]'s description correctly states that it can be consumed to heal {{color|green|15 FP}} instead of {{color|red|10 HP}} like in the original game.
**The [[Zess Frappe]]'s description correctly states that it can be consumed to heal {{color|green|20 FP}} instead of {{color|red|20 HP}} like in the original game.
**The [[Fright Mask]]'s description has been changed to mention that the item does not always succeed.
**Any instances of {{color|red|"your"}} or {{color|red|"allies"}} referring to an item's effect has been changed to {{color|green|"a party member,"}} since they can apply to either Mario and his partner.
**The wording of {{color|red|"Wearing two or more of these badges requires more FP for the Attack power."}} has been changed to {{color|green|"Wearing two or more of these badges increases the Attack power, but the move will require more FP."}} to be more clear.
**[[Power Bounce]] lists how many recorded bounces in a row Mario has, rather than it being written on the sign outside the Pit of 100 Trials.
**Tornado Jump's description is more specific, saying {{color|green|"can deal additional damage to all midair enemies"}} rather than {{color|red|"can damage all midair enemies."}}
**The new descriptions specify when an effect is temporary.
**The description for the [[Up Arrow]] says it should be given to {{color|green|"somebody... super"}} rather than merely {{color|red|"somebody"}}, giving a clearer hint toward its purpose (that it should be given to [[Merlon]] to allow him to upgrade partners from Super Rank to Ultra Rank).
**Badges have longer descriptions that appear in the Badge List.
*Yellow Blocks, Stone Blocks, and Metal Blocks are written in title case rather than sentence case. The bigger versions are now called Big Yellow Block and Big Stone Block.
*The ? Blocks that hold badges are now called Red ? Blocks.

====Character dialogue and story====
*[[Dupree]] and [[Cortez]]'s dialogue in the English version incorporates a larger variety of French and Spanish words and phrases, respectively, often accompanied with their English translations, rather than just a few simple untranslated words and phrases. For example, instead of {{color|red|"Sacre bleu!"}}, Dupree now says {{color|green|"Je suis blessé—I am wounded!"}}, and instead of {{color|red|"You are foolish, amigo! For I do not live!"}}, Cortez says {{color|green|"Estúpido! You are foolish indeed! For I do not live!"}}.
**The French and Spanish words in their dialogue now have their proper accents, such as Cortez saying {{color|red|"You rattle my bones, Senor Peacock!"}} being corrected to {{color|green|"You rattle my bones, ''Señor'' Peacock!"}}.
**Dupree's stereotypical mock French spellings of English words are changed to their proper English spellings.
;Rogueport
*In the original game, when Mario enters the town square of [[Rogueport]] for the first time, [[Goombella]] states that she is merely a "student at the [[List of implied organizations#University of Goom|University of Goom]]", while in the remake, she specifically states that she is a junior at the school. 
*The line "To find the treasure of yore, take the seven Crystal Stars to the Thousand-Year Door" was said by Goombella in the original game, but in the remake, it is said by [[Professor Frankly]] instead. 
*Professor Frankly no longer says "{{color|red|And you there! In front of the TV!}}" but instead "{{color|green|In front of the screen!}}" to account for the player possibly playing in handheld mode. In turn, Mario's partners' responses to this line also no longer mention the word "TV".
*When [[Swindell]] robs Mario of half of his coins, Goombella's dialogue is changed from "{{color|red|Mario! You gotta wake up! That guy just stole half your coins! That is SO lame! Ugh! I HATE this town!}}" to "{{color|green|The guy bumps into you and just runs off like that... Unbelievable! Some people are so RUDE!}}". Therefore, the only indication that Swindell has stolen from Mario is the decreasing visual of the coin counter. This change was likely made to align with Goombella's Tattle for Swindell, which claims that he's never actually been seen stealing from anyone despite having the reputation of being a thief.
*When Professor Frankly finishes his research on how to go to the Moon, Goombella notifies Mario of this.
*[[Ms. Mowz]] no longer describes her own abilities in her partner primer after she joins Mario's party, with the controls for her abilities being given by blue textboxes similar to those of other party members.
*Rather than [[Jerry]] being traumatized over seeing Luigi in a dress, he says that Luigi wore stilettoes and kept tripping over them and knocking people over, so he wants to prevent that from happening again.
*In both the original English and Japanese versions,<ref>[[Paper Mario: The Thousand-Year Door|ペーパーマリオRPG]] "このみのタイプはね···<br>としした<br>ボクよい 年下で ちっちゃくて<br>セクシーよいは プリテイかな?"</ref> [[Goom Goom]] describing that the girl he wants would be younger than him ({{color|red|"Petite, younger than me, and pretty, not drop-dead hot"}}) which university student [[Goombella]] ends up meeting, has been omitted. He instead describes his criteria as {{color|green|"about my age, short like me, and Goomba-shaped"}}.
*Peeka's Tattle was changed from {{color|red|"That's Peeka, a Boo that works at Westside Goods. She's so pretty... for a Boo. I think her sister's Lahla, the Boo who works at the Pianta Parlor."}} to {{color|green|"That's Peeka, a Boo that works at Westside Goods. She's so pretty... and surprisingly un-shy!"}}.
*Grifty’s tale about the Crystal Stars is changed slightly: the line {{color|red|"One of these stars was placed in each country"}} is replaced with {{color|green|"The stars were scattered across the land"}}.
*In Grifty’s tale Dragons and Dungeons, it is now stated that {{color|green|"The dragons’ remains have never been found"}} and that some people fear they may still be alive, rather than people simply being scared by the {{color|red|"mere mention of a dragon"}}.
;Rogueport Underground
*A scene from both the original English and Japanese versions<ref>[[Paper Mario: The Thousand-Year Door|ペーパーマリオRPG]] "こんなかわいいねえちゃん<br> 赤まえのような<br> ヒゲオヤジには にあわねせ"</ref><ref>[[Paper Mario: The Thousand-Year Door|ペーパーマリオRPG]]"ねえちゃんねえちゃん<br>オレたちと あせばねえか?<br> かわいがってやるからよ"</ref> of the group of enemy Goombas encountered early cat-calling [[Goombella]] (saying {{color|red|"Wassup, baby? Why don't you hang with us for a while? We play real nice!"}}, and her defending herself saying {{color|red|"guys like you make me feel like TOTALLY BARFING!"}}), has been omitted. The dialogue now instead has the enemy Goombas insult Mario for being from the surface.
*[[Wonky]]'s tale "''Z Button''" has been completely removed, pursuant to the removal of being able to view previous dialogue messages. As a result, Wonky has one less tale than in the original game.
*Some of Wonky's tales have changed. 
**When he talks about seeing Peach, he says "{{color|green|And I probably should’ve spoken up before now, so…oops.}}" instead of "{{color|red|People get kidnapped, whatever.}}".
**Wonky's description of spin panels is longer: "{{color|green|When you Spin Jump near a spin panel...a Star Piece might pop right out! Score! Problem is, they look just like regular flooring, so it's tricky to find 'em. Spin panels will jump up just a bit if you hit the ground nearby with a hammer though. Might be worth it to hit the ground here and there and look for them.}}" instead of "{{color|red|When you Spin-Jump a spin panel... It bumps a Star Piece right out of the ground! Score! Problem is, they look just like regular flooring, so it's hard to tell.}}".
**When talking about Lahla, Wonky no longer encourages Mario to woo her. He now says "{{color|green|You should go there and get to know her. Folks say she’s super chatty…but only if you’ve got skills! And I ain't.}}" instead of "{{color|red|You should get in there and see how good your game is, Mr. Popular!}}".
**Wonky's tale on saving money has changed to accommodate the new cap of 9999 coins. He says "{{color|green|Did you notice that you can carry up to 9,999 coins? Well, if you ever want to collect more coins than that, you should buy Gold Bars from the shop near here… Usually when you sell items, you get less than what it costs to buy ‘em. But with Gold Bars, some shops will pay more than their selling price! “But Wonky, my trusted financial advisor,” I hear you say, “what should I do if I’m close to havin’ 9,999 coins?” Why, then you buy a few Gold Bars and store ‘em at a shop! I call that a retirement plan…and you can too!}}" instead of "{{color|red|Did you notice that you can only carry up to 999 coins? Well, if you ever want to collect more you should buy Gold Bars at the shop near here and then store them at the shop, where you can convert them back to coins anytime. They may sell for slightly less than you buy them for, but it's better than losing all the coins you wouldn't be able to pick up, right?}}".
**One line where Wonky talks about the town legend has changed from "{{color|red|I see that you wear red and blue}}" to "{{color|green|red and blue seem like your kind of colors}}", because the line is no longer accurate if Mario has the L or W Emblem badges equipped.
**Wonky no longer says he wants to have a date with Merlee. His tale says "{{color|green|Ol' Wonky’s gotta give a full disclosure though. Tampering with magic isn’t for everybody. Her charms work, but they make ol' Wonky smell like bananas. Cursed by the stench of the sleeve-fruit!}}" instead of "{{color|red|Not only that, but she's a total babe... Ol' Wonky would LOVE to get a date with her! I'm serious. You have to check her out sometime.}}".
*[[Dazzle]] no longer accuses Mario of trying to swindle him if Mario talks to him with no Star Pieces.
*Merlee is no longer referred to as a "fortune-teller", with every instance changed to her being a "charmer". This descriptor is also used occasionally in the original game.
*Merlee has a bit of extra dialogue related to her shop:
**She explains what her charms do: {{color|green|"On my spells and magic I must tattle— they'll bring more profitable battles. How long before each spell will end? That depends on the coins you spend! But on the form of my blessing... there's no knowing, only guessing!"}}
**She will now warn Mario if he is about to buy a charm with one already active.
**If Mario tries to buy a charm that he does not have enough coins for, she will say he must choose a cheaper one.
**The charms are listed in reverse order compared to the original game.
*Many of Merluvlee's predictions have been modified slightly to change how she refers to the place. For example, Fahr Outpost goes from {{color|red|"the cold village"}} to {{color|green|"the snowy outpost"}} and "{{color|red|the train-refueling depot"}} to {{color|green|"a midpoint station where a beautiful train frequently stops."}}. Minor corrections have also been made, such as referring to an {{color|green|"archway of roses"}} instead of a {{color|red|"rose hedge"}} in Poshley Heights, or the {{color|green|"chests and barrels"}} instead of the {{color|red|"chests and boxes"}} in Hooktail Castle's treasure room.
;Petal Meadows
*The ending text on the sign to Hooktail Castle's pipes has changed from {{color|red|"If ye are a Petalburg Koopa, huzzah! Your HOLD ability maketh this chore a snap!"}} to {{color|green|"This challenge is easyeth-peasyeth if ye use the skill of a Petalburg Koopa!"}}.
;Petalburg
*The Toad kid who plays the next ''Paper Mario'' game summarizes it with {{color|green|"if you're a Luigi fan...this game will only encourage you!"}} instead of {{color|red|"if you're a Luigi fan, do NOT miss out on this one!"}}.
*The [[Koopa Troopa]] obsessed with Princess Peach tells Mario not to touch any of the one-of-a-kind collectables inside his house instead of talking about Hooktail and the rumors of treasure hidden within her castle. A different Koopa Troopa outside discusses these rumors instead.
*[[Koopley]]'s "patented fighting technique" is [[Shell Toss]] instead of [[Power Shell]].
;Path to Shhwonk Fortress
*Goombella's statement on trying to open the doors in the Path to Shhwonk Fortress is removed.
;Hooktail Castle
*Hooktail's weakness is stated to be frogs instead of crickets, like in the original Japanese script. As a result, the [[Attack FX R]] badge found in Hooktail Castle, used as a weakness for Hooktail when equipped, has been replaced with [[Attack FX G]], which now makes frog noises.
**Due to the changes in names, [[Attack FX P]] can be purchased from Charlieton for 120 coins and the sound of Mario's attack changes of Princess Peach giggling, and Attack FX R can be purchased from the Lovely Howz of Badges after Chapter 6 for 100 coins and it changes to the sound of Bowser growling.
*Hooktail no longer mentions a {{color|red|"strange-garbed one who came earlier"}}. It is unknown who she was referring to with this in the original game.
*When Hooktail offers to let Mario smell her feet after defeating her first phase, she no longer states that {{color|red|"People pay good money to do this. I'm being completely honest right now. Really."}} She also now tells Mario that it is a {{color|green|"one-time offer"}}.
*When Koopley emerges from Hooktail's gut, he states Hooktail {{color|green|used the smell of her feet to stun him}} when she swallowed him instead of simply stating {{color|red|Hooktail played a trick on him}}. This change is also in the Japanese version.<ref>[https://youtube.com/watch?v=-7b08lEn3pM] GC版からSwitch版で変更されたセリフ集【ペーパーマリオRPG】.
''YouTube''. Retrieved July 5, 2024.</ref>
*The narration after collecting the [[Diamond Star]] has been changed to include more details. It is now as follows: {{color|green|"Using the Magical Map they received from  Princess Peach, Mario and his friends claimed their first Crystal Star. With the deadly dragon Hooktail defeated, the citizens of Petalburg would rest easy once again. Koops even reunited with his long-lost father, whom he thought was dead. And yet, despite victory in the castle, Princess Peach’s whereabouts were still unknown. Where could she be? Yes… It seems Mario’s adventure has only just begun."}}.
**All other chapter end narrations are unchanged from the original game.
*Koopook says {{color|green|"But... since you found me this time, I'll give you what I promised."}} instead of {{color|red|"But... since you found me this time, I'll give you a reward, like I promised."}} This is because the player already knows what the [[Special Card|reward]] is, as it is now mentioned in the trouble request. 
;Boggly Woods
*When Flurrie's door is locked, Mario's partner makes a comment. Goombella and Koops both have extra lines suggesting Flurrie could be out of the house:
**Goombella: {{color|green|"Oh, huh. Maybe the owner is out right now. Should we go back or what?"}} instead of {{color|red|"Call me crazy, but I think this place is totally deserted. Should we go back or what?"}}.
**Koops: {{color|green|"Hey, I don't think anyone's home. The owner must be out right now... Maybe we should take off."}} instead of {{color|red|"Hey, I don't think anyone's home. It's too quiet... Maybe we should take off."}}.
;The Great Tree
*Goombella's Tattle on Magnus von Grapple has an extra comment: after she says, "The thing about this robot is I can't tell if it looks cool or really, REALLY stupid...", she adds, {{color|green|"And we're not even going to discuss the color."}}.
;Glitzville
*[[Stewart]] says "{{color|green|The next Cheep Blimp is bound for the town of Rogueport.}}" instead of "{{color|red|This Cheep Blimp is bound for the town of Rogueport.}}". This is slightly more accurate, as it is the same blimp both times.
*When first arriving in Glitzville, Koops worries that the place will fall out of the sky. In the original game, he says {{color|red|"I mean, it hasn't ever, you know, plunged from the sky or anything, has it?"}}, and in the remake, he says {{color|green|"It will...stay floating, right?"}}.
*[[Mr. Hoggle]]'s lines have all been changed, likely due to his stereotypical Chinese portrayal in the original game.
**His shouting at the Yoshi Kid's egg has changed from {{color|red|"No! Bad! So very bad! Behave yourself, egg!"}} to {{color|green|"No! Stop that at once! This behavior is unacceptable in a foodstuff! I insist you desist!"}}.
**He says {{color|green|"Please! Come back to me! Someone, help! My rare, imported egg has escaped! Please catch it!"}} instead of {{color|red|"No! Bad! Come back! Help! My imported egg escaped! Somebody, catch it!"}}.
**He says {{color|green|How dreadful! I'm helpless to catch it, despite its total lack of arms OR legs! However shall I make my famous Spotted Egg Dog now? Woe is me! I ordered that incorrigible egg from an island in the south! THERE WERE ASSOCIATED SHIPPING COSTS! Well, don't just stand there! Help me catch it!}} instead of {{color|red|"So bad! It does not even have arms and legs, and still I cannot catch it! My menu was going to have the Southern Fried Egg Dog of Tastiness, but now...  Bad! I ordered that naughty egg from an island in the south! I had to pay shipping, too! Don't just stand there! Help catch it!!!"}}.
**He says "{{color|green|ABSOLUTELY UNACCEPTABLE IN A POLITE SOCIETY! I insist you come down at once, egg! How am I to reach you up there? FLY?! Like a common sparrow?!}}" instead of {{color|red|"MOST AWFULLY BAD! Come down from there, bad egg! How am I supposed to get it now? FLY there?!? You! Don't just stand there with your mustache! Find a way to get up there!"}}.
**In the original game, if Mr. Hoggle is talked to after the egg falls asleep on top of the cart, he repeats an earlier statement asking how to reach it, then says, {{color|red|"Oh... And I very much wanted to make that Southern Fried Egg Dog of Tastiness..."}}. In the remake, this line has been removed entirely.
**His line asking Mario to buy Hot Dogs has changed from {{color|red|"Hello there, you customer! The aroma of yum in the air is the specialty of Glitzville, Mr. Hoggle's famous Hot Dogs! Only 10 coins for 1! You will buy one?"}} to {{color|green|"A very good day to you, my very good man! You have no doubt noticed Glitzville's many aromas? Well, the finest of them is Mr. Hoggle's famous Hot Dogs! Only 10 coins apiece! May I tempt you?"}}.
***If Yoshi Kid is there too, he says {{color|green|"A very good day to you! Perchance, did that...creature with you used to be my runaway egg? Why, yes, it hatched from that incorrigible egg! I suppose it's for the best that I didn't cook it... Now, are you interested in a Hoggle Hot Dog? Still only 10 coins apiece! May I tempt you?"}} instead of {{color|red|"Hello there, you customer! That thing with you used to be my runaway egg, I think! Yes, that hatched from that naughty egg! I guess it's good I didn't cook it... Now, have a Hoggle Hot Dog? Still only 10 coins for 1! You will buy one?"}}.
**When Mario buys a Hot Dog, he says "{{color|green|Thank you ever so!}}" instead of "{{color|red|Thank you, you customer!}}".
**If Mario tries to buy a Hot Dog without having enough coins, he says {{color|green|"Ah. You unfortunately don't seem to have the, er, necessary resources to purchase a Hot Dog. How awkward."}} instead of {{color|red|"Hmm... You need more coins or you will never sample the savory yum of this Hot Dog. That's too bad for you. You come back again!"}}.
**If Mario tries to buy a Hot Dog but has too many items, he says {{color|green|"I'm afraid your current storage is not up to the challenge of a Hot Dog. Sell, store, or use an item, perhaps?"}} instead of {{color|red|"Your inventory is full! Why don't you sell, store, or use something?"}}.
**His exit line has changed from {{color|red|"Thanks plenty!"}} to {{color|green|"Come again!"}}.
**He no longer says {{color|red|"I give thanks to you. You have [number] shop points."}}.
**After buying a Hot Dog, Mario is given the option to buy another, with the prompt {{color|green|"My Hot Dogs cost a mere pittance of 10 coins apiece. May I tempt you with more?"}}. This is not in the original game.
*The egg's sleeping sounds have went from to "{{color|red|ZZZZZZZZZZZ... ZZZZZZZZZZZ...}}" to just "{{color|green|.........}}".
*In the remake, the partners' reactions to the egg have it specifically mention that it doesn't want to be eaten, and all of them have "{{color|green|Should we help?}}" added after "What should we do, Mario?".
**Goombella: {{color|red|"You want us to help you, little eggy-weggy?"}} to {{color|green|"You don't want to be eaten, little eggy-weggy?"}}.
**Koops: {{color|red|"You want our help, egg?"}} to {{color|green|"You don't want to be eaten, egg?"}}.
**Flurrie: {{color|red|"You wish for us to help you, you darling little egg?"}} to {{color|green|"You don't want to be eaten, you darling little egg?"}}.
*After Mario agrees to help the egg, the partners' responses all have them directly ask Mr. Hoggle if it's okay for them to take it.
**Goombella: {{color|red|"I am TOTALLY with you on this one, Mario. We'll let you go, little buddy! Is that OK with you, too, Mr. Hot-Dog-Stand Guy?"}} to {{color|green|"Mr. Hot-Dog-Stand Guy... it looks like this egg doesn't want to be eaten. It's OK to let it go, right?"}}.
**Koops: {{color|red|"Yeah, we can't ignore it... Good call, Mario. Let's set this little guy free. Ummm... Provided that's OK with you, too, sir."}} to {{color|green|"Sir— it looks like this egg doesn't want to be eaten. It's OK to set this little guy free, right?"}}.
**Flurrie: {{color|red|"A positively endearing choice, Mario, not that I expected any less. We shall free him! You, sir! Mr. Proprietor! Would you allow us to free this poor soul?"}} to {{color|green|"You, sir! Mr. Proprietor! It looks like this egg doesn't want to be eaten. It's OK to free this poor soul, yes?"}}.
;Glitz Pit
*Master Crash's first bit of advice has been shortened and made more accurate: it goes from {{color|red|"If you clear the conditions and win, you get to fight higher-ranked foes BOMB! If you can't clear them, you BOMB end up battling a lower-ranked fighter BOMB! You can't climb the BOMB ranks fighting the bottom of the barrel BOMB-BOMB!"}} to {{color|green|"If you can't clear the conditions and win, your rank won't go up even if you win the match BOMB."}}.
*Master Crash's advice now has a new line where he suggests that Mario take on Exhibition Matches to earn money to buy items.
*[[King K]]'s dialogue has been rewritten to avoid using the terms "dog" and "homey" (typically replacing them with "man" or "dude"), as well as changing misspellings of common words (i.e. {{color|red|"What, you off KO'in fools lef an' right somewhere else?"}} to {{color|green|"What, you off KO'ing fools left and right somewhere else?"}}) and adding dropped verbs (i.e. {{color|red|"You lookin' good, man."}} to {{color|green|"You're lookin' good, man."}}). As with Mr. Hoggle, this may be a sensitivity change, since his original dialogue was a stereotypical depiction of {{wp|African-American Vernacular English}}.
**Similarly, when speaking about his grandfather, [[Hamma Jamma]] says {{color|green|"World 7-1, those were his hoppin' grounds..."}} rather than {{color|red|"World 7-1, that was his hood..."}}.
*King K's line about hot dogs has changed from {{color|red|"Hey, man, check this: I heard the Hot Dog Stand outside's gettin' a new menu item. Yeah, sounds like it's some crazy Hot Dog made with an egg from a southern island. Some fool was even sayin' the Hot Dog'll help you win fights! You oughta snack out on one!"}} to {{color|green|"Hey, man, check this—I heard the hot-dog stand outside's gettin' a new menu item that uses a Mystic Egg! Did you know? Their Hot Dogs can restore your HP and FP during a match. That's some serious nutrish! I'm not sponsored—YET—just excited about some probably-amazing Hot Dogs! You oughta snack out on one!"}}.
*King K's comment on seeing Jolene at the juice shop has been rewritten to be less flirty. In the original game, he says {{color|red|"Hey, you hear the latest, G-dog? My boys said they saw a STUNNIN' babe havin' a juice at the Fresh Juice Shop. King K could use a little shortie in his life, dig? Check her out for me, man!"}}. In the remake, he says {{color|green|"Did you hear the latest, G-man? My boys said they saw a STUNNIN' babe havin' a juice at the fresh-juice shop. She likes juice... I like juice... We already have so much in common! Check her out for me, man!"}}.
*In the Castilian Spanish localization, Rawk Hawk's line {{color|red|"¡Los aficionadillos deberían quedarse en casa jugando al 'Super Smash Bros. Melee'!"}} ({{color|red|"The weaklings should stay home playing ''[[Super Smash Bros. Melee]]''!"}}) is changed to {{color|green|"¡Los aficionadillos deberían quedarse en casa jugando al «Super Smash Bros.»!"}} ({{color|green|"The weaklings should stay home playing ''[[Super Smash Bros. (series)|Super Smash Bros.]]''!"}}).
*In the Japanese script, Rawk Hawk's title has been changed from {{color|red|「人間原子力はつでんしょ」}} ({{color|red|"The Human Nuclear Reactor"}}) to {{color|green|「金色の　ぼうそうはつでんき」}} ({{color|green|"The Golden Uncontrollable Generator"}})<ref>{{cite|author=7Roggie|date=May 27, 2024|url=https://x.com/7Roggie/status/1795029922328526926|title=ただ単にテキストを変更するんじゃなくて、よりゴールド・ホークらしいリングネームになっているのが良い|language=Japanese|accessdate=May 29, 2024}}</ref>; this is likely due to nuclear power generation being a controversial topic in Japan after the {{wp|2011 Tōhoku earthquake and tsunami}}. Likewise in the English script, his title has been changed from {{color|red|"The Feral Nuclear Reactor"}} to {{color|green|"The Golden Grandstander"}}.
;Twilight Town
*The [[Twilighter]] shop manager's wife's dialogue has been changed from {{color|red|"I wish he wouldn't dip into the till for cola money, but boys will be boys, y'know?"}} to {{color|green|"I wish he wouldn't dip into the till for cola money—that part of him really needs some work, y'know?"}}, likely due to the modern negative connotations of the phrase "boys will be boys".
;Twilight Trail
*The Amazee Dayzee's tattle log entry has part of it changed from {{color|red|"Since it has such a high amount of HP, and because it's so quick to run away, this creature is almost impossible to beat."}} to {{color|green|"It has high HP and is quick to run away. Something good might happen if you can defeat it!"}}.
;Creepy Steeple
*Goombella has a new Field Tattle for the belfry following the completion of Chapter 4 ("This is the belfry of Creepy Steeple. Every time this bell rung, a villager would be turned into a pig...").
;Keelhaul Key
*Lord Crump no longer says "{{color|red|And hey! You! Out there in front of the TV! Yeah, I'm talking to you!}}" but instead "{{color|green|And hey! You! Out there in front of the screen! Yeah, I'm talking to you!}}" to account for the player possibly playing in handheld mode. In turn, Mario's partners' responses to this line also no longer mention the word "TV".
*The last line in Goombella's Field Tattle for the jungle has been changed from "{{color|red|I think there's an invisible block here somewhere, so why don't you look for it?}}" to "{{color|green|Let's keep our eyes open as we explore this place! You never know what might pop out...}}".
*In the original game, when interacting with the rock in which the [[Skull Gem]] fits, a blue textbox appeared to explain that the rock has a hole that looks like something might fit inside before Mario's active partner wonders about what could fit in the hole. In the remake, Mario's active partner comments on the rock without the blue textbox appearing.
;Fahr Outpost
*The Bob-ombs no longer incorporate "Da" into their explosion catchphrases, possibly in light of {{wp|Russian invasion of Ukraine|Russia's invasion of Ukraine}} at the time of the game's release. Nintendo of Europe SE had previously suspended all operations in Russia in 2023 as a result of the invasion.<ref>{{cite|author=Leah J. Williams|date=June 1, 2023|title=Nintendo eShop to shut down in Russia|url=https://www.gameshub.com/news/news/nintendo-eshop-shut-down-russia-june-2023-2618374/|publisher=Gameshub|language=English|accessdate=July 6, 2024|archive=https://web.archive.org/web/20240225053424/https://www.gameshub.com/news/news/nintendo-eshop-shut-down-russia-june-2023-2618374/}}</ref>
;Palace of Shadow
*The unique messages from the plaques in the Palace of Shadow Tower have been changed in the English version. After all Tower Keys have been used, the messages are then shown on the screen, arranged in a poem: "The stars up in the heavens shone; Carrying the lore of the sky; Carrying secrets from on high; By skill and might, engraved in stone. Stones to rival the celestial spheres; The seven hewn by a fell hand; Feared far and wide across the land; Master of shadow, queen of fear."
**The messages now appear on the top line of text on the plaques instead of being in the center line in the original game. The messages are also colored in light blue text instead of dark blue.
*When Bowser picks a fight with Mario in the Palace of Shadow, he declares that he will take {{color|green|the Crystal Stars}} instead of {{color|red|the treasure}}.
*Grodus has a new line before reviving the Shadow Queen stating that the Crystal Stars will undo the seal placed on her coffin. His final line has been changed such that he is struck down by the Shadow Queen mid-sentence: "Or I will send you back to the depths—"
;Epilogue
*On the ride back home, Peach says {{color|green|"Maybe I shouldn't wander off by myself quite so often."}} instead of {{color|red|"Maybe I should listen to Toadsworth and behave more like a princess from now on..."}}
*In the ending cutscene, when Goombella visits Vivian, the text was changed from {{color|red|"Vivian's gone back to hang out with her sisters. Family is important after all..."}} to {{color|green|"Vivian's gone back to hang out with her sisters. She wants to give them another chance."}}.
;Intermissions
*Certain dialogue was altered in the Chapter 5 intermission. When Peach is made invisible, TEC-XX states that her dress still being visible is a {{color|green|"tactical error"}}. Unlike in the original game, he does not explicitly ask for Peach to remove her dress. Because of this, Peach does not object to being forced to undress and instead does so by her own volition.
;Email
*[[Koopook]] refers to himself as {{color|green|The Hide-'n'-Seek Koopa}} instead of the {{color|red|The Hide 'n' Seek Koopa}} in his email to Mario. 
*The emails from [[Jolene|X]] have the subject line of {{color|green|"No subject"}} instead of {{color|red|"No title"}}. 
*[[Zip Toad]]'s email is sent from {{color|green|"Zip Toad <small>(Verified)</small>"}} rather than {{color|red|"The Real Zip Toad"}}, and the subject line is {{color|green|"What's up!"}} rather than {{color|red|"!"}}.
;Trivia Quiz-Off
*The 65th Super Fun Quirk Quiz is renamed to the [[65th Trivia Quiz-Off]], matching the [[64th Trivia Quiz-Off]] from ''[[Paper Mario]]''. Likewise, the 66th Annual Quirk Quiz is renamed to the [[66th Trivia Quiz-Off]].
*For the first question of the 65th Trivia Quiz-Off, the answer "{{color|red|Stone Keys}}" has been changed to "{{color|green|Sun and Moon Stones}}." to accomodate their new names.
*For the second question of the 65th Trivia Quiz-Off, the [[Thwomp]] asks how much a [[Mushroom]] and [[Fire Flower]] cost total at [[Petalburg]] instead of a [[Mr. Softener]] and Fire Flower, matching the original script.

====Terms and insults====
;The term "airhead"
*Uses of the term "airhead" in the original have been replaced.
**[[Lord Crump]]'s insult to [[Goombella]] in the prologue has been changed from {{color|red|"Oh come off it, you airhead!"}} to {{color|green|"Oh come off it! I know you're a nosy book nerd[...]"}}. 
**The insult [[Bowser]] uses to address [[Kammy Koopa]] is changed from {{color|red|"AIRHEAD!!!"}} to {{color|green|"LUNKHEAD!"}} during his intermission after completing Chapter 1.<ref name=Direct/>
;The term "dork"
*Uses of the term "dork" in the original have been replaced, seemingly due to the word also being slang for "penis".
**When the player talks to [[Goom Goom]] with the Yoshi Kid as the active partner for the [[Looking for a gal!]] Trouble, the Yoshi Kid now calls Goom Goom a {{color|green|bozo}} instead of a {{color|red|dork}}.
**When first meeting [[Dupree]] in Petalburg in Chapter 1, Goombella refers to him as "{{color|green|Bozo the Chump}}" instead of "{{color|red|Bozo the Dork}}."
**If Koops is Mario's active partner when meeting Ms. Mowz in the Glitz Pit storeroom, Koops now states "{{color|green|Too bad I sound like such a nerd whenever I talk to her.}}" after Ms. Mowz leaves instead of "{{color|red|Too bad I sound like such a dork whenever I talk to her.}}"
**When Lord Crump throws the [[Superbombomb]] at Bowser and his army during the post-Chapter 5 Bowser intermission, he now states "{{color|green|Eat this, turtle dolts!"}} instead of "{{color|red|Eat this, turtle dorks!}}".
;The term "spook"
*Some uses of the term "spook" have been replaced. This is likely due to the word's alternative use as an ethnic slur.
**Grubba no longer says {{color|red|"What in the hey?!? Dang ceilin' is spookin' me!"}}
**Ghost T's email replaces "{{color|red|Long time, no spook! It is I, the spirit from the Excess Express!}}" with "{{color|green|Your inbox is now haunted by me, the spirit you met on the Excess Express!}}"
**However, Bowser still says Twilight Town is "spooking [him] out," and the word "spooky" is always left intact.
;Goombella's comments regarding Ms. Mowz
*When meeting [[Ms. Mowz]] in Chapter 1 in [[Hooktail Castle]], [[Goombella]] originally saying {{color|red|"You little flirt!"}} and {{color|red|"What a flirt! Who acts so disgusting like that?"}} has been omitted. She instead says {{color|green|"Stop that smooching!"}} and {{color|green|"There's no way you'd fall for all that flirting, right, Mario?"}}. 
*Goombella no longer calls [[Ms. Mowz]] a "floozy", likely due to to its sexual and gendered nature.
** When encountered in Chapter 2 in [[The Great Tree]], Goombella previously said {{color|red|"Who do you think you are, you total floozy?"}}. She now says {{color|green|"This flirting is out of control!"}}.
** When using [[Tattle]] in the encounter room, Goombella previously said {{color|red|"Ms. Mowz was here before, but I think she took the next train to Floozyville"}}. She now says {{color|green|"Ms. Mowz was here before, but I think she took the next train to Flirtsville"}}.
** When encountered in Chapter 3 in the [[Glitz Pit]], Goombella previously said {{color|red|"Are you, like, the biggest floozy or what?"}}. She now says {{color|green|"Are you trying to set a world record for flirting or what?"}}.
;Terms referring to body weight
*Nearly all original dialogue referring to body weight has been rewritten.
**The Black Chest [[Curse]] in [[Hooktail Castle]] that gives Mario [[Paper Mode]] originally said {{color|red|"Eat a sandwich, skinny!"}}. It now says {{color|green|"You'll try to jump or move and you'll probably just wobble there!"}}.
**The Thwomp running the first quiz calls Mario a {{color|green|"blockhead"}} instead of a {{color|red|"fathead"}} if he fails too many questions.

**During [[Flurrie]]'s tutorial, the line {{color|red|"She can also do a Body Slam in battle, squashing enemies with her...stage presence."}} was changed to {{color|green|"She can also squash enemies in battle with a Body Slam or blow them all away with Gale Force!"}}.
**Goombella's tattle on Macho Grubba, where she is surprised at his transformation, says "{{color|green|he was just regular ol' Grubba a moment ago}}" instead of "{{color|red|he used to be that chubby Grubba}}."
**In the original, when [[Grubba]] expressed disbelief at his loss, he said, {{color|red|"Noooo... How'd this happen? How could a perfect bod like mine lose to such a chub?"}} In the remake, he instead says, {{color|green|"Noooo... How'd this happen? How could a perfect bod like mine lose to such a schlub?"}}.
**Issue 4 of Rogueport Today describes the [[Healthy Salad]] as {{color|green|"Perfect for your next gathering of herbivores,"}} rather than {{color|red|"Great for dieters!"}}.
**The [[Twilighter]] that says he wants to be {{color|red|"a big ol' FAT one"}} rather than {{color|red|"a skinny pig"}} if he becomes a pig now simply says he wants to be {{color|green|"a big one"}} rather than {{color|green|"a pipsqueak pig"}}.
**When confronting [[Heff T.]] about the missing soup, he says {{color|green|"Oh, I get it! Food gets stolen and you blame ME right away with no evidence! NOT NICE!"}} rather than {{color|red|"Oh, I get it! Food gets stolen and you blame the chubby guy! NOT NICE!!!"}}.
**After falling through the floor in the Palace of Shadow, Bowser blames it on {{color|green|"Crummy ancient-tower construction"}} rather than suggesting he put on weight ({{color|red|"Have I put on weight?"}}). Kammy Koopa then refers to him as {{color|green|"His Impactfulness"}} rather than {{color|red|"His Chunkiness"}} in the original game.
;Terms referring to disability
*Most instances of "lunatic", "psycho", "crazy", "insane", "nuts" and similar terms used as insults or intensifiers are replaced with alternatives, likely due to increased sensitivity regarding their usage to refer to people with mental disabilities. Relatedly, uses of "lame" as a synonym for "uncool" have also been changed, as the term is used to refer to people with physical disabilities. 
**[[Goombella]]'s insults to [[Lord Crump]] and the [[X-Nauts (platoon)|X-Nauts]] in the prologue have been changed from {{color|red|"Like I'd go anywhere with smelly lunatics like you!"}} and {{color|red|"What a bunch of loons!"}} to {{color|green|"Like I'd go anywhere with smelly losers like you!"}} and {{color|green|"What a bunch of bozos!"}}, respectively.

**When the [[Magical Map]] is updated for the first time, [[Goombella]] asks {{color|green|"And what was with all those strange lights?"}} instead of {{color|red|"And what was with all those crazy lights?"}}.
**During the tutorial for using [[Paper Mode]], if the player stopped holding the button, the [[black chest]] would say {{color|red|"You idiot! Press and hold {{button|gcn|R}}! Press and hold {{button|gcn|R}} and be ashamed!"}}. In the remake, this line is {{color|green|"What are you doing?! Press and hold {{button|switch|ZR}} and be ashamed!"}}.
**The Toad kid in Petalburg has been playing ''The Thousand-Year Door'' {{color|green|"a lot"}} instead of {{color|red|"like crazy."}}.
**When tattling a [[Bub-ulb]] in Petalburg, Goombella now says that he {{color|green|"makes more sense than than these other quirky Petalburgers"}} rather than {{color|red|"crazy Petalburgers."}}.

**If Mario asks the [[Puni elder]] to summon the Punies while they are trapped in the cages, the elder asks if Mario is {{color|green|"funny in the head"}} rather than {{color|red|"crazy in the head."}}.
**In the Great Tree, Goombella says, {{color|green|"Did you feel that? That intense shaking?"}} instead of {{color|red|"Did you feel that? That crazy shaking?"}}.
**Inside The Great Tree during Chapter 2, [[Lord Crump]]'s insult to the [[Puni elder]] has been changed from {{color|red|"What?!? Are you nuts?"}} to {{color|green|"What?! Are you for real?"}}.

**Describing [[Master Crash]], [[King K]] says {{color|green|"My man has, you know, some quirky speech goin' on, but his advice holds up most of the time."}} rather than {{color|red|"My man's got, you know, some speech issues, but he's got good advice sometimes."}}. This is likely due to "speech issues" implying that Master Crash has a disorder rather than simply a verbal tic.
**One of the Glitz Pit NPCs says {{color|green|"This is a bit out of the blue, but I really wouldn't mind being the strongest guy alive."}} instead of {{color|red|"This'll sound crazy, but I really wouldn't mind being the strongest guy alive."}}.

**In Chapter 3, after [[Mario]] defeats [[Bowser]], [[Grubba]]'s commentary, {{color|red|"Hoo! That's our Gonzales! He don't even bat an eye when some nut ambushes him!"}} was changed to {{color|green|"Hoo! That's our Gonzales! He don't even bat an eye when some fool ambushes him!"}}.
**When Mario is told by the communicator that his match privileges are revoked, Yoshi Kid says {{color|green|"Hey, what's going on here?! Did X do this too?"}} instead of {{color|red|"What's this crazy talk, huh? Did X do this, too?"}}.
**[[Spiky Joe]] says {{color|green|"There's no way a mustache is better than a spike! I mean, that's just nonsense!"}} instead of {{color|red|"There's no way a mustache is better than a spike! I mean, that's just crazy-talk!"}}.
**Goombella's tattle for Macho Grubba was changed to say {{color|green|"Then he powers himself up with all sorts of wild, power-uppy moves."}} instead of {{color|red|"Then he powers himself up with all sorts of crazy, power-uppy moves."}}. She also says {{color|green|"the wildest thing"}} instead of {{color|red|"the craziest thing"}}.
**Goombella's tattle for Hyper Goombas says "{{color|green|but if this guy goes BIZZ-ZOW and charges up}}" instead of "{{color|red|but if this nut goes BIZZ-ZOW and charges up}}".
**One of Goombella's tattles for the pigs in Twilight Town says {{color|green|"He seems like a happy guy...even as a pig. Some people are just like that, I guess!"}} instead of {{color|red|"Do you think that this guy was so gloomy that he's even a gloomy pig? ...That's crazy!"}}.

**Before the start of Chapter 5, Frankly explains that the Crystal Stars are unable to tell for what purpose they are being used, whether it is good or evil. If Koops is active, he says, {{color|green|"I dunno, maybe we oughta just shatter those things."}}. In the original game, he says {{color|red|"Call me crazy, but maybe we oughta just shatter those things."}}.
**During Chapter 5, the lines {{color|red|"Flavio, what are you talking about? That's crazy!"}} was changed to {{color|green|"Flavio, what are you talking about? There's no way that'll work!"}}.
**When Bobbery thinks he has died, Goombella says, {{color|green|"You're still alive, you zany old coot!"}} rather than {{color|red|"You're still alive, you crazy old coot!"}}.
**[[Frankie]] calls [[Francesca]] a {{color|green|"dizzy dame"}} rather than a {{color|red|"crazy dame"}} before saying "I love you" 100 times; similarly, [[Don Pianta]] calls Francesca and Frankie {{color|green|"lovebirds"}} rather than {{color|red|"crazy kids"}} when the duo return to Rogueport before Chapter 6.
**When Frankly suggests that Mario talk to Don Pianta to get train tickets, Yoshi Kid says {{color|green|"Whaaat?"}} instead of {{color|red|"Are you crazy?!?"}}. He also says that Don Pianta {{color|green|"sounds intense"}} rather than {{color|red|"sounds like a loon."}}.
**In Chapter 6, after Mario picks up the [[Threatening Note]], Goombella's, the [[Yoshi Kid]]'s, and Vivian's responses were changed.
***Goombella's final textbox was changed from {{color|red|"Ooh, I HATE threats! Let's get this nutjob before they try anything!"}} to {{color|green|"Ooh, I HATE threats! Let's get this sneak before they try anything!"}}.

Before anything bad goes down on this train!"}}.
***Vivian's final textbox was changed from {{color|red|"We have to find who's responsible before anything crazy happens!"}} to {{color|green|"We have to find who's responsible before anything bad happens!"}}.
**On the Excess Express, Zip Toad's line "So... {{color|red|lame...}}" was changed to "So... {{color|green|uncool...}}".

====Genders====
*[[Hooktail]] is consistently referred to with feminine pronouns. Up until the battle with [[Gloomtail]] in the original game, Hooktail is referred to with masculine or neutral pronouns. Additionally, she is no longer referred to as a {{color|red|"cad"}} during her battle, as by definition only men can be cads, and Koops calls her a {{color|green|"gal"}} instead of a {{color|red|"guy"}}. 
**Oddly, Goombella's field tattle in Hooktail's lair is left unchanged from the original game, still referring to her as "it." 
*[[Bonetail]] is female in the English version as with other localizations.
*The {{color|red|Shadow Sirens}} have been renamed to the "[[Three Shadows]]," a more accurate translation of their Japanese name, the Shadow Trio. Also, [[Vivian]] accidentally refers to the group as the {{color|green|"Shadow Sisters"}} instead of {{color|red|"Shadow Beauties"}} like in the original game. This is also a more accurate translation of the Japanese text. After this occurs, [[Beldam]] states {{color|green|"RELATION WITHHELD"}}.
*Vivian's portrayal as a transgender woman is more overt, with the Japanese version adding in dialogue where she says {{color|green|「体は　オトコのコだけど ココロは　カワイイ　オンナのコなの」}} ({{color|green|"I have a boy's body, but my heart is a cute girl's!"}}).<ref>{{cite|author=OatmealDome|date=May 21, 2024|url=https://x.com/OatmealDome/status/1793081375005827084|title=(Paper Mario: TTYD) Here's the original Japanese for this Vivian line. それに　じつは　アタイ・・・ 体は　オトコのコだけど ココロは　カワイイ　オンナのコなの "The thing is...

**The Japanese script removes lines that refer to Vivian as male; for example, Beldam's line {{color|red|「どこが　三姉妹だよ！あんた　オトコじゃないかい！」}} ({{color|red|"Where do you see three sisters?! Aren't you a man?!"}}) is replaced with {{color|green|「三姉妹じゃなく　三人組だって　いつも　いってるじゃないかい！」}} ({{color|green|"I always tell you we're a trio, not three sisters!"}}).<ref>{{cite|author=e3ka33ri|date=May 22, 2024|url=https://x.com/e3ka33ri/status/1793478907641122965|title=ここのセリフ変わっとる！！！！！！！！！ＧＣ版だと「あんたオトコじゃないか！」ってマジョリンが言ってたしビビアンは「つい…」としか言ってなかったのに|language=Japanese|accessdate=May 26, 2024}}</ref> Goombella's Tattle about Vivian also removes any mention of her gender,<ref>{{cite|author=OatmealDome|date=May 21, 2024|url=https://x.com/OatmealDome/status/1793116364783104093|title=Goombella's tattle was also updated to remove all mentions of Vivian's gender in Japanese. Instead, she goes on a little ramble about Vivian being cute and how she might be a bit jealous. This was kept for the English translation.|language=English|accessdate=May 26, 2024}}</ref> meaning she is not stated to be transgender until she reveals it to Mario in Chapter 4. Additionally, Goom Goom's line {{color|red|「おお！　これは　かわいい…　ってキミ…　どうちなの？…　オトコ…　だよね…　ようするに　オスじゃん！」}} ({{color|red|"Ooh! You're cute... but what's... up with you? You're a boy... aren't you...?

*The game's few instances of "he or she" have been changed:
**Peach's explanation of love says {{color|green|"When you love someone, you will do anything to help when that person in trouble"}} instead of {{color|red|"When you love someone, you will do anything to help when he or she is in trouble"}}. Note that this introduces a grammatical error; a verb is missing between "that person" and "in trouble".
**When Bobbery reads the Threatening Note, he says {{color|green|"Let's roust this swine before they have the chance to cause mischief!"}}. In the original game, he says {{color|red|"Let's roust this swine before he or she has the chance to cause mischief!"}}.
**Strangely, Goombella's Twilighter tattle that includes the line "I have no idea if he or she's gloomy or jolly or what" is left unmodified.

====Important Items====
*Several Important Items have been renamed:
**The {{color|red|Dubious Paper}} has been renamed to {{color|green|[[Dubious Documents]]}}.

**The {{color|red|Wrestling Mag}} has been renamed to {{color|green|[[Wrestling Magazine]]}}.

**{{color|red|"Price Adjustment"}} to {{color|green|"Competitor research!"}}
**{{color|red|"Order me an item!"}} to {{color|green|"Help me restock!"}}
**{{color|red|"Emergency Shroom!"}} to {{color|green|"Life Mushroom!"}}
**{{color|red|"Play with me!"}} to {{color|green|"Come over and play!"}}
**{{color|red|"I must have that book."}} to {{color|green|"I need my magazine."}}
**"[[Get these ingredients!]]" had part of the description changed from {{color|red|"savages the tonsils"}} to {{color|green|"ravishes the senses,"}} and the formatting on the list of ingredients is different.
**Troubles that reward Pianta Parlor cards say so in their description, whereas the reward went unmentioned in the original.
**"Help wanted!" specifies that Mario needs to talk to Jolene in the promoter's room, rather than just "in the Glitz Pit."
**The description for "I need my magazine." states where Toodles is in Poshley Heights.

===Graphical changes===
;General
*The entire game has a higher screen resolution and a more detailed look, using a more realistic crafted style similar to entries starting from ''[[Paper Mario: Sticker Star]]'' onward. For example, characters have a thicker paper texture more similar to cardstock, which resembles—but is not identical to—the white outlines seen on characters in ''[[Mario & Luigi: Paper Jam]]'', ''[[Paper Mario: Color Splash]]'', and ''[[Paper Mario: The Origami King]]''. 3D objects such as [[pig]]s have visible construction seams on them, more objects are 3D models, and surface textures are generally more reflective.<ref name=Direct/> To go alongside these changes, dynamic lighting is present extensively in many areas. As another example, the [[Crystal Stars]] have a more realistic shiny texture than the original game.
*The game runs at 30 frames per second,<ref>https://www.nintendolife.com/features/hands-on-paper-mario-the-thousand-year-door-unfolds-gloriously-on-switch</ref> which is half of the 60 frames per second that the original game runs at.
*The curtains open to reveal the title screen, which does not happen in the original game. They also remain closed when accessing the file select screen.
*Menus have a 3D, cardboard-cutout appearance rather than being flat like in the original game.
*Due to the widescreen resolution, the HUD elements, transitions, and some interiors have been redesigned to accommodate the extra horizontal space. Framing in several cutscenes and some background scenery has also been readjusted to go alongside these changes.
*A loading icon appears in the bottom-right corner of the screen when loading scenes depicting miniature icons of the Crystal Stars arranged in a ring similar to the [[Big Paint Star]] ring used in the loading icon for ''Paper Mario: Color Splash'' and the [[streamer]] ring for ''Paper Mario: The Origami King''.
*Locations, and sub-locations thereof, have their names shown on the bottom-right corner of the screen, such as "Rogueport Sublevel One" or "Creepy Steeple Sublevel Two". In the Japanese version, Levels are listed numerically.

*The pictures in [[Kroop]]'s, [[Toce T.]]'s, and [[Koops]]'s houses are more detailed. In Kroop's house, the pictures show a younger Kroop and his late wife. Meanwhile, in Toce T.'s house, the pictures show a blue [[Toad (species)|Toad]] and a house. Finally, in Koops's house, the three pictures show [[Hooktail Castle]], a [[Candy Pop]], and [[Koopley]] respectively.

*The Puni Orb pedestal has an indentation in the shape of the orb to place it in instead of a rectangular indentation.
*There is always a panel that shows where to place the Punies instead of the panel only being in some locations. An indentation to indicate where Mario should stand to blow the Punies is also added.

*One Jabbi entering the small hive room brings the [[Blue Key (Paper Mario: The Thousand-Year Door)|Blue Key]] with it, instead of entering empty handed.
*In the maze room, an arrow pointing down towards [[Pungent's Great Tree Shop]] was added.

*When the Punies fight against the Jabbies, their antennae become glowing red when they attack, similar to Pikmin using an Ultra-Spicy Spray.
*After the fights with the Jabbies, the pieces of the destroyed Jabbi hives appear broken on the ground instead of disappearing, sirens included.

*Marks were added to where the stairs move when the blocks are hit to better indicate the stairs' three possible positions.

===Battle changes===
*Mario and partners no longer walk in place when selecting an enemy to attack. Instead, they take a fighting stance.
*Mario no longer drops coins when running away from regular battles.
*After winning a battle, the enemy's dropped coins appear in a smaller, more circular area rather than being spread out.
*There is an option on the bottom right corner of the screen known as "Tattle Check" that is accessed with {{button|switch|plus}}. Tattle Check allows the player to view Tattle entries for enemies in the current battle that have been previously Tattled and does not waste the player's turn doing so.
*Getting hit by enemy projectiles in the field no longer initiates a battle, instead damaging Mario on the spot like in entries since ''Paper Mario: Sticker Star''. Likewise, getting hit by enemy projectiles while equipped with the Bump Attack badge does not defeat enemies, either.

*Enemies now initiate their turn after any [[Star Power]] accumulation from the player's turn is finished. In the original game, the enemies' turn begins during this.

*Hammer Bros. in the audience throw hammers in situations aside from "Mario failed a Hammer action command".
*Mario and his partner visibly take a defensive posture during the frames an attempted Guard or Superguard is active.
*[[Spring Jump]] has a subtle sound cue to communicate its timing, a low whistling pitched to Mario's height.
*The frame window for [[Power Bounce]] and [[Multibonk]] is changed to make it harder to make big combos with them. The frames to hit it now is 7, 7, 6, 1, 5, 4, 3, 2, 1, etc. Even Simplifier does not change the frame perfect 4th hit window, as it is hard locked to 1.
*It is possible to skip the cutscene before a boss fight after losing once and returning to the boss room.<ref>Nintendo Life. (May 21, 2024). [https://www.youtube.com/watch?v=3ZPwyfIL_qU Paper Mario: The Thousand-Year Door Nintendo Switch Review - Is It Worth It?]. ''YouTube''. Retrieved May 21, 2024.</ref>
*Some enemy attacks have new animations and/or visuals to increase clarity of block timing. For example, Magnus von Grapple's earthquake stomp has a larger stomp at the end and Crayzee Dayzees have an extra music note that collides directly with the target.
*[[Sweet Treat]] only spawns two Poison Mushrooms, down from three in the original.
*If the player performs [[Earth Tremor]] while their partner is afflicted with the Sleep status effect, or Koops is flipped, a Black Shy Guy stagehand carries the partner off the stage for the duration of the attack.
*[[Power Lift]] requires four panels matched for each point of attack or defense increase, down from five in the original.
*The game distinguishes between two different types of "no damage". If an attack did no damage but could have if it were stronger, it is shown to deal "0" damage. If an attack did no damage and nothing could have allowed it to, there are no damage stars at all, combined with a white sparks effect. In the original game, a small star graphic was shown for both situations.
*When using an attack that the target is elementally immune to, such as a fire-element attack on Clefts, an icon with that element crossed out now appears over the enemy.
*It is significantly more difficult to wake up a character that is asleep by attacking them. Most attacks are incapable of doing so at all. Charged attacks and stage hazards have a 100% rate of waking. Some enemy attacks have various other rates.<ref>https://www.youtube.com/watch?v=LskQk9bmtAM&t=218s</ref>
*Status effect applications are shown by having its icon appear on the subject. If a status is attempted but failed, the icon visibly bounces off.
*Several status effects have different icons.
**The Attack Up icon is an arrow with a fist, while the Defense Up icon is an arrow with a [[Courage Shell]]. Both contain an extra number showing the magnitude of the boost. There are also new icons for Merlee's boosts, visible during the brief time after she takes effect before the attack is used.
**The [[Huge]] and [[Tiny]] icons are now a sized circle with expanding or contracting arrows.
**The [[Allergic]] icon shows a green figure inside a green-tinted bubble instead of a speech bubble with a flashing general prohibition sign.
**The [[Fast]] icon is two triangles in a fast-forward configuration.
*When a character charges more than once, the number shown in the arrow is the new total charge power, rather than only the charge of the current usage.
*Current HP numbers for enemies are center aligned beneath their health bars instead of being aligned to the right.
*Upon the start of non-First Strike battles, enemies that enter the stage steel themselves for battle.
*Upon the start of non-First Strike battles, the entire backdrop of the stage has either fold-in or popup animations rather than only specific parts of the backdrop having these animations in the original game.
*The player can no longer hold A for a faster battle ending theme.
*If Mario jumps on a Bristle in battle, his tears are more visible, and his mouth is closed instead of opened.
*The non-damaging hits of [[Love Slap]] do not displease the audience for potential loss. Ms. Mowz no longer turns red while winding it up, and she walks backwards returning after using the move.
*Boss fights begin with a slow motion shot before the curtain drops instead of the curtain dropping immediately following the end of the pre-battle cutscene dialogue.
*At the end of boss fights, the winning hit goes into slow-motion and the screen flashes white.
*Coins are shown to rain down on Mario and his partner after completing battles that award coins, such as boss battles or battles in the Pit of 100 Trials.

====Text====
*There is a {{color|green|"GUARD"}} or {{color|green|"SUPERGUARD"}} text pop-up that appears when the player successfully performs a [[Guard]] or [[Superguard]]. Doing so against unblockable attacks will show the text appearing but being knocked away. The original game displayed the standard {{color|red|"NICE"}} or {{color|red|"GREAT"}} text instead.
*The message for the Star Points earned after winning a battle is shortened to {{color|green|"Got Star Points!"}} ({{color|green|"Got a Star Point!"}} when earning a single Star Point) with the amount earned separated in its own graphic to the right of the Star Points. In the original game, the message reads, {{color|red|"You got [X] Star Point(s)!"}}
*The "Excellent" rating is yellow colored rather than gold and silver.
*"Nice" ratings that are weakened by [[Simplifier]] are progressively greyed out, rather than progressively smaller.
*The [[Allergic]] status effect's description has been changed from {{color|red|"Status hasn't changed!"}} to {{color|green|"Can't be affected by status changes!"}}, which more accurately describes its effect.
*Enemy tattles list the first place they were tattled on rather than their natural habitats.

====Specific battles====
;Normal enemies
*Bob-ombs, [[Bulky Bob-omb]]s, and [[Bob-ulk]]s no longer drop Star Points if they are defeated by a chain reaction.
*Chain Chomps stop bouncing around when targeted by a jump-like attack, making the timing more predictable.
*Like the first ''[[Paper Mario]]'', [[Frost Piranha]]s can use an ice breath attack to freeze Mario's party. They can no longer freeze the party with their bite.
*[[Swoopula]]s can use the swoop attack like [[Swoop|Swoopers]] instead of only being able to use a drain attack like in the original game.
*The Buzzy Beetle family is immune to explosions even when flipped upside-down.
*[[Dark Bristle]]s can no longer be hit by a First Strike with the Super or Ultra Hammer.
*[[Dark Craw]]s clench their fist and no longer have splayed fingers for their sprites.
*If Mario defeats a [[Big Bandit]] before it can run away after it has stolen an item, the item will be recovered. In the original game, the only way to recover stolen items from Big Bandits was to have [[Ms. Mowz]] use [[Kiss Thief]] on them, as Big Bandits are only fought in the [[Glitz Pit]], meaning that the stolen items could not be dropped and picked up following the end of the battle.
*Flying shelled enemies, if hit by a multi-hit jump-like attack, are considered flipped by the second jump and therefore have no defense from the third bounce onward. In the original game, the enemy was not considered flipped until they finished landing on the ground, after the attack is over.
*Flower Fuzzies only attack Mario.
;Blooper
*During the fight, the water in the background is animated instead of standing still.
*Upon its defeat, the Blooper's shaking causes visible splashing water and its eyes are crossed from dizziness.
;Hooktail
*When Hooktail uses her fire breath attack, Mario and his partner are completely engulfed in flames instead of appearing as black outlines in the fire.
*Hooktail lowers her head into a more convenient position when targeted by a jump-like attack, making the timing more predictable.
*The last part of the battle is fought in front of the seats instead of in the middle of them. Because of this, the camera is pulled back further, meaning that the walls surrounding the stage are visible during the battle. The clock on the left wall is also visible during the battle instead of only being visible after the battle ends.
*When Hooktail is defeated, her tail can still be seen extending onto the stage instead of her body being completely absent from the stage like in the original game.
;Macho Grubba
*He briefly glows gold when powered up instead of white like in the original game.
;Doopliss
*The positions of the furniture in the battle background are flipped to better resemble the appearance of his room in the cutscene prior to the start of the battle.
*He can damage Mario during the battle that occurs in the shed area of [[Twilight Trail]]. Mario still cannot damage him, however.
*When running away from him during an encounter on Twilight Trail, the run away meter starts from a more filled position than it did in the original game, making it easier for the player to successfully run away from the battle.
*The first time he takes damage in the second battle, he will have a shocked expression and comment on it.
*The animation when he scans Mario or his partner is a ring with square effects instead of a straight line.
*If he is defeated during the second battle before Vivian joins mid-fight, he uses a Life Mushroom to revive himself.
*During the second fight, badges that affect Mario's partner function as normal, unlike in the original where they are disabled.
;Cortez
*At the beginning of the battle, he drops onto the stage from above instead of already being on stage when the battle starts like in the original game.
;Gloomtail
*Gloomtail lowers his head into a more convenient position when targeted by a jump-like attack, making the timing more predictable.
*Gloomtail's Megabreath is an intense stream of fire instead of a yellow coloration of breath attacks used by the dragon bosses in the original game.
;Shadow Queen
*The body of her true form and her Dead Hands have a puddle of darkness and black smoke beneath them. In the original game, it is only black smoke.
*Her spells are no longer shadowy or black in coloration as they are in the original game.
**Her lightning spells are yellow instead of black and pink.
**Her strongest attack no longer makes the area darken as a sphere of purple energy manifests from her body instead. The waves produced afterwards glow purple instead of appearing all black.
*When charged, only Peach has the rainbow color overlay, when in the original game the Shadow Queen's body has it as well.
*Her breath attacks glow and have more curving patterns.
*When defeated, she turns into a large cloud of black smoke that disappears from the stage. In the original game, only the body of her true form disappears, leaving the possessed Peach intact.
;Bonetail
*Bonetail lowers her head into a more convenient position when targeted by a jump-like attack, making the timing more predictable.
*The color of her confusion status-inducing breath has been changed to pink from green in the original game.

====Battle rewards====
*Bosses award the player coins after being defeated.
**Blooper, Atomic Boo, Smorg, Gloomtail, Sir Grodus, and Bowser with Kammy Koopa reward 50.
**Hooktail, Magnus Von Grapple, Macho Grubba, Doopliss (both fights in Creepy Steeple), Cortez, Magnus Von Grapple 2.0, and Whacka reward 100.
**The Shadow Queen rewards 200.
**Bonetail rewards 999.
*The player earns coins for winning battles in the Pit of 100 Trials.
*The Shadow Queen no longer rewards the player with a single Star Point.

====Stage hazards====
*Stage Hazards pierce Defense.
*The visuals for whether a stage hazard only affects one side of battle are much clearer.
*Falling objects are briefly visible before they actually fall, giving more time to react.
*Fog covers the entire height of the stage, rather than simply the bottom.
*Depending on the move used and its target, fog may only be removed from one side of the stage at a time.
*Nozzles no longer fall down and stay down. Instead, they fall down only when they are about to fire, and are reset by [[Black Shy Guy]] stagehands afterward.
*When a stage hazard hits Mario or his partner, the enemy has a new animation mocking them.

===Cutscene changes===
;Intro
*The storybook intro sequence is animated. If all four save files currently are empty, the intro also comes after the title screen after starting a new save file rather than before it.
*During the scene where Peach buys the treasure chest containing the [[Magical Map]] from the Rogueport [[Beldam|merchant]], the text has to be advanced manually instead of auto-advancing like it did in the original game.
*In the opening shot of Mario's house, [[Parakarry]] has his arms raised to the mailbox as he delivers Peach's letter, as opposed to the mailbox just rattling with him next to it.
*The [[Mario Bros.' House]] has a group picture of Mario's partners from the first ''[[Paper Mario]]'', and during the ending cutscene, the group picture of Mario's partners from ''The Thousand-Year Door'', as a call-forward to ''[[Super Paper Mario]]'' featuring said pictures. The map inside the house has also been changed to the world map from ''Paper Mario'', and the exterior of the bedroom was sectioned to match its design from that game.<ref name=Direct/>
*When Peach's letter is being read in the opening cutscene, it is displayed over a black background before cutting to the first view of Rogueport, where the letter itself no longer becomes visible at the bottom of the screen.
*On the logo screen, the camera pulls back and down from the Sun, which is itself much higher in the sky, and the boat transporting Mario to Rogueport is much closer to the camera. The boat also no longer stops in the center of the screen until the player presses the {{button|switch|a}} button, instead continuing across the screen and auto-advancing to the next scene.
*When Mario opens his eyes to see Rogueport in front of him for the first time, the transition from the black screen is in an elliptical shape instead of a barn-door wipe.
;Rogueport
*After the boat drops Mario off in Rogueport for the first time, Mario is initially facing towards the left instead of towards the right like in the original game.
*After the prologue fight, Lord Crump appears on the right side of the [[X-Nauts (platoon)|platoon of X-Nauts]] instead of in the center of them.
*After escaping from [[Lord Crump]] and the X-Nauts in the prologue, [[Mario]] and [[Goombella]] turn around to acknowledge the fight between [[Tony (Paper Mario: The Thousand-Year Door)|Tony]]/[[Vinny]] and [[Gus]]/[[Garf]].
*Just before the start of Chapter 5, the X-Naut reporting the infiltration is no longer standing behind a wall but behind the barrels behind the ship.
*The whole party is visible while riding the [[Blimp|Cheep Blimp]] instead of just Mario.<ref name=Direct/>
*In the scene where [[Lucky]] gets angry to Mario for cheating, Mario's partner freaks out with Mario instead of standing still.
;Black chests
*When a black chest face curses Mario, he gets struck by lightning, while in the original, the screen flashes white while Mario is cursed.<ref name=Direct/>
;Thousand-Year Door
*All of Mario's partners are present each time he holds the [[Magical Map]] before [[the Thousand-Year Door]].<ref name=UKPreview/>
*The Magical Map starts off in a sepia tone, with each location filling in with color as its corresponding Crystal Star is located by holding it aloft before the Thousand-Year Door. New details that are added to the map also unfold like a pop-up book. The corresponding Crystal Star appears next to its location on the map in a bright white flash, no longer continuously sparkles, and is immediately stationary on the map instead of appearing from a star-shaped sparkle, continuously sparkling, and spinning in 3D briefly in front of its location on the map before becoming stationary.
*The order of the stars lit up on the Door differs.
*The effect of the entire screen segmenting and rippling outwards from the Magical Map after a new Crystal Star location is recorded is no longer present.
;Petal Meadows
*When exiting the pipe to Petal Meadows, Goombella no longer stays on the pipe but jumps down. The camera also stops zooming in further away from her and Mario.
*Mario and Goombella now look directly upwards when [[Hooktail]] flies overhead.
*Hooktail is seen flying towards her castle from behind as the camera moves down to ground level rather than from the side as the camera pans horizontally like in the original game.
*In the cutscene where Koopie Koo is worried about Koops leaving with Mario, she has a worried expression on her face instead of her normal smiling expression like in the original game. She is also visibly angry before attacking them and the appearance of her back sprite when she turns has been corrected.
;Hooktail Castle
*In the cutscene prior to her battle with Mario, Hooktail emerges from the shadows into the light. The sunlight streaming through the windows into her lair is much brighter than in the original game.
;Bowser's Castle
*In Bowser's Castle's, the candles on the chandeliers and the torches by the door are now lit.
;Boggly Woods
*Flurrie's introduction cutscene is different, as the camera pans up from below and she sends the rose petals surrounding her towards Mario with a kiss. The cutscene is also one of the few pre-rendered cutscenes in the game.
;The Great Tree
*The cutscene where the X-Naut gets knocked down by Ms. Mowz happens when the player enters the room, instead of before entering the room with the cells holding the Punies.
*The Puni Elder grows much bigger in her confrontation with Lord Crump. She also has an angered expression rather than her expression remaining neutral.
*The [[Emerald Star]] appears in front of Mario at the front of the room instead of behind him in front of the Puni Orb pillar. In turn, Lord Crump steals the Emerald Star from the front of the room instead of from behind the Puni Orb pillar.
*Lord Crump's remote is black with a yellow button instead of white with a red button.
*If the timer runs out while talking to Lord Crump, all characters have a freak out animation just before the bomb goes off.
*The yellow horns on Magnus von Grapple's dome are visible prior to its battle with Mario.
*Instead of walking into Mario and his partner to start the battle, Magnus von Grapple jumps into them.
*Beldam holds the wanted poster of Mario that was previously unused in the original game.
;Glitz Pit
*Mario reacts to Grubba's question after the first fight against [[The Goomba Bros.]] with an animation, which differs between each answer.
*When one of Mario's partner eats the poisoned cake, a new animation (unique for each of them) is used instead of them just collapsing on the floor.
*Grubba visibly hands Mario the Champ's Belt after the Rawk Hawk match. Mario is visibly wearing the Champ's Belt during the rest of the cutscene.
*After defeating Macho Grubba, Grubba wobbles on his feet while speaking before falling down after finishing his dialogue rather than immediately lying down after his defeat like in the original game.
*Prince Mush no longer just flies out of the machine and stands on the stage looking fine, instead initially appearing in a spirit form before falling to the stage, lying on the ground, and standing up on one knee like he is in pain before standing with a tired expression.
*In the cutscene after completing Chapter 3, Prince Mush is present and posters of Mario are seen on the walls.
;Twilight Trail
*The first secret hole in the last area is off center to make navigation easier.
;Creepy Steeple
*[[Doopliss]] is seen rocking in his chair upon his introduction at the [[Creepy Steeple]] instead of simply sitting in the chair like in the original game.
*The bell at the top of Creepy Steeple rings just before each fight with Doopliss there.
*Prior to beginning the battle with Doopliss after correctly guessing his name, Vivian now visibly cries and turns around before teleporting away after realizing she was unknowingly helping Mario rather than remaining behind Mario like in the original game.
*The way Doopliss and Mario's transformations are undone is different from the original game, with Doopliss appearing to have two pieces of paper ripped off of him rather than just spinning and reverting to normal and Mario's shadow form appearing to be peeled off of him like a sticker rather than just Mario returning to normal.
;Keehaul Key
*In the beginning cutscene of Chapter 5, when the S.S. Flavion is surrounded by Embers, the Embers now attack the ship by pushing it, causing Four-Eyes and Admiral Bobbery to be thrown overboard, followed by the ship being turned over on its side. In the original game, Four-Eyes abandons ship and the S.S. Flavion eventually sinks.
;Pirate's Grotto
*The whirlwind from which [[Cortez]] emerges shows visible coins and gemstones being blown around within it.
*Instead of remaining stationary, Cortez's head opens its mouth and lunges toward Mario and his partner to start the battle
;Excess Express
*When reading [[Ghost T.]]'s diary, the scene has a black-and-white grain filter applied on it and now fades to black slowly rather than spinning around.
*The magenta [[Smorg]]s are not visible in the cutscene before the battle.<ref name=UKPreview>@NintendoUK (April 18, 2024). [https://x.com/NintendoUK/status/1781246360504746032 "''A scary dragon atop a tall tower? A cursed town full of…pigs? A train ride packed with high-speed hijinx? All this and more awaits you in #PaperMario: The Thousand-Year Door!''"] ''X''. Retrieved April 24, 2024.</ref>
*When the Excess Express arrives at Riverside Station, [[Doopliss]] (in his [[Zip Toad]] disguise) is shown being tied up in ropes before breaking free.
;Fahr Outpost
*The [[moon]] is seen when Mario and his party are launched from the cannon in [[Fahr Outpost]].
;X-Naut Fortress
*TEC-XX no longer scans the whole fortress before focusing on Peach in the first Peach intermission, possibly to avoid spoiling the facility's location (in the original, one shot showed stars and the Moon's surface).
*In Princess Peach's post-Chapter 3 intermission, the conversation between Sir Grodus and the disguised Peach plays out as a cutscene, whereas in the original game, Peach had to walk up to Grodus to talk to him.
*The entire post-Chapter 7 ending sequence in the X-Naut Fortress is significantly modified:
**During TEC-XX's last speech to Mario, his dialogue gradually begins to tremble (at first just the ellipses, and then the entirety of the text).
**Rather than the standard X-Naut Fortress music, the cutscene is at first silent. When TEC-XX mentions that he will cease to function, a somber arrangement of Peach's theme begins playing. This somber arrangement continues to play as Mario makes his way to the teleporter room.
**The line "TEC system failure reported," has been removed. Instead, when TEC-XX shuts down, the red hazard lights immediately turn on with an accompanying sound effect.
**The elevators no longer say "Choose your destination" after TEC-XX shuts down, instead simply showing the floor prompt with no dialogue attached.
**After Mario takes the teleporter, the lights in the fortress shut down, followed by an alarm, signaling the fortress's impending destruction.
**TEC-XX's line "Peach...Goodbye..." is no longer displayed in a text box, and instead appears in the center of the screen. The somber arrangement of Peach's theme plays one last time over this scene, instead of ambient sound effects as in the original game.
;Palace of Shadow
*When the flames of the candles change color, the color of the rug changes to blue instead of remaining red like in the original game.
*Hand-like shadows cover the world when the Shadow Queen awakens instead of regular shadows, in a similar vein to the "Night on Bald Mountain" segment from the Disney film ''{{wp|Fantasia (1940 film)|Fantasia}}''.
*When striking down Sir Grodus, the Shadow Queen's lightning spells are colored red and much larger then in the original game, where they were ordinary sized and colored black and pink.
*In all regions, the bad ending shown when Mario accepts the Shadow Queen's offer reflects the Japanese version of the original game. Mario takes on the appearance of Doopliss's copy (retaining the Emblems he has equipped), rather than simply having an angry expression. Additionally, the music fades out and the ending text in this scene takes up the whole screen, rather than being confined to a text box.
*Several characters are added to most areas during the scene where they encourage Mario through the Crystal Stars in his battle with the Shadow Queen:
**'''Rogueport:''' [[Flavio]], [[Don Pianta]], [[Frankie]], [[Francesca]], [[Zess T.]], [[Mousimilian]], [[Charlieton]], [[Podley]], [[Ishnail]], [[Gus]], [[Goose]], [[Plenn T.]], [[Swindell]], [[Vinny]], [[Tony (Paper Mario: The Thousand-Year Door)|Tony]], [[Goomther]], [[Luigi]], and [[Toadsworth]].
**'''Petalburg:''' [[Bub-ulber]].
**'''The Great Tree:''' [[Jabble]] (only if he was recruited during Chapter 2).
**'''Glitzville:''' [[Prince Mush]], [[The Koopinator]], [[Sir Swoop]], [[Mr. Hoggle]], [[Podler]], [[Bandy Andy]], and the [[Businessman]]. An error from the original game is also corrected, where [[Shellshock]] appeared in this cutscene speaking like [[King K]]. In the remake, King K himself appears in Shellshock's place.
**'''Twilight Town:''' The shopkeepers.
**'''Keelhaul Key:''' The [[Traveling Sisters Three]], [[Thriff T.]], and [[Dupree]].
**'''Poshley Heights:''' The [[Excess Express conductor]], [[Excess Express engineer]], [[Excess Express waitress]], and [[Chef Shimi]].
*General White is in the center of the Bob-omb crowd encouraging Mario through the [[Crystal Star]] instead of being behind them in front of the door to his house like in the original game.
*The speech bubbles that appear to cheer on Mario and co. look different. The one from Pennington is all written in one bubble, rather than requiring several.
*Mario goes first to check on Peach after the Shadow Queen is defeated instead of his partner.
*After the final battle, Frankly is shown having just entered the Palace of Shadow instead of simply being in one of the palace's rooms.
;Ending
*In the epilogue after the final boss, a curtain no longer descends before showing Flurrie in the "Paper Mario" stage play.
*Instead of the camera zooming towards Mario in the ending cutscene, a snapshot of the scene is shown, which then transitions into an illustration of a page in the storybook seen in the opening cutscene. The storybook then closes and the desk lamp the book was next to shuts off, like in the ending of ''Paper Mario: Sticker Star''.

===Audio changes===
*Because the boat carrying Mario to Rogueport for the first time no longer stops in the center of the logo screen until the player presses the {{button|switch|a}} button, with the scene auto-advancing instead, the music that plays if the player remains on the logo screen without pressing the {{button|switch|a}} button no longer plays.
*Tying into the revamped email mechanics, the jingle for receiving an email (based on the theme that plays after defeating a Koopaling in ''[[Super Mario World]]'') is much shorter and faster, now being a simple trill rather than the entire theme.
*When approaching Hooktail Castle in the background, menacing ambience sounds fade in rather than the standard Petal Meadows theme continuing to play like in the original game.
*The "reunion" music plays at the end of Chapter 1, when Koops announces his intention to join Mario after rescuing his father, rather than the standard Petalburg music.
*After completing Chapter 2, the interior of the Great Tree continues to play its standard theme. In the original game, the Punis' theme played inside the Great Tree after completing Chapter 2.
*The eerie howling sound that periodically played in Creepy Steeple and the choir voices in the Palace of Shadow are both no longer present.
*Lord Crump's theme plays when he is talked to during the post-Chapter 5 Bowser segment and in the epilogue scene with the X-Nauts. In the original game, his theme only played during two cutscenes in Chapter 2.
*[[Pennington]]'s theme plays when he confronts Bowser in Poshley Sanctum.
*Princess Peach's theme no longer plays when Mario explores the western rooms of Sublevel Four of the X-Naut Fortress.
*The second theme of the Palace of Shadow now plays in the corridors leading to Gloomtail's lair even if the orrery in the Palace of Shadow Tower has not yet been activated.
*The Chapter 8 introduction theme is replaced by continuing the current theme for the Thousand-Year Door room.
*There is no music after Grodus escapes from his battle.
====Music arrangement====
*The game's music has been rearranged with new instrumentation and a similar style to later entries in the ''Paper Mario'' series. Furthermore, several songs are extended with new melodies. The original soundtrack can still be played via equipping the Nostalgic Tunes badge.<ref name=Direct/>
**Much of the remake's soundtrack is recorded with live players, including a big band, an orchestra and choir, and world music instruments, rather than being entirely synthesized as in the original game. As a result, the rearranged soundtrack incorporates more elements of jazz, rock, and orchestral  music compared to the original game's techno and chiptune influences.
**Several areas have more dynamic music. Each level of [[Rogueport Underground]] now has its own variant of the standard theme music, as does the [[X-Naut Fortress]].
**Similar to ''Paper Mario: Color Splash'' and ''Paper Mario: The Origami King'', the main battle theme changes to different arrangements specific to each area. Also like in the final areas of both games, the field theme continues playing during battles in the [[Palace of Shadow]] (except inside the Tower).
**Similar to ''Paper Mario: Color Splash'' and ''Paper Mario: The Origami King'', each battle theme has its own unique victory theme to go along with it. However, the unique version of the victory theme that plays when Mario's current partner has run out of HP has been removed and does not play even with the Nostalgic Tunes badge equipped.
**Like the first ''[[Paper Mario]]'', as well as all games since ''[[Paper Mario: Sticker Star]]'', each battle theme's intro changes depending on whether the player or the enemy gets the first strike.
**Like in ''Paper Mario: The Origami King'', each battle theme now changes to a quieter "thinking" variant if no action is made for some time.
**The regular battle theme begins with the opening [[Ground Theme (Super Mario Bros.)|Ground Theme]] motif from ''[[Super Mario Bros.]]''.
**Bowser's theme incorporates parts of "Bowser's Castle" from ''Paper Mario: The Origami King''.
**The "reunion" music features a unique arrangement for each chapter it plays in.
**The track that plays in the room where the Thousand-Year Door dwells has variations in which different instruments join each time a Crystal Star has been collected, similar to the world map in ''Paper Mario: Color Splash'' and [[Toad Town]] in ''Paper Mario: The Origami King''.
**When Peach waltzes with TEC-XX, there are various different versions of the music that can play. If Peach messes up her steps and performs worse, the music becomes off-key, and eventually a metronome is added to make the rhythm easier to follow.

====New music tracks====
*New music tracks have been added.
**When [[Parakarry]] delivers the Magical Map to the Mario Bros.' House and when talking to [[Lady Bow]] in the post-game, an arrangement of the title theme from ''Paper Mario'' can be heard.
**As Luigi reads Princess Peach's letter at the beginning of the game, an arrangement of "[[Inside the Castle Walls]]" from ''Super Mario 64'' plays instead of the theme of the [[Mario Bros.' House]] continuing to play over the letter.
**A new ambient theme plays  while lingering on the chapter introduction screen.
**All of the partners, as well as several other characters—such as [[Kroop]], [[Koopie Koo]], [[Goldbob]], and [[Flavio]]—have their own themes that play when they are being focused on.
**New battle themes have been given to several of the game's bosses, with certain bosses that originally shared themes, such as [[Magnus von Grapple 2.0]], [[Gloomtail]] and [[Bonetail]], receiving new renditions of their original themes and [[Big Boo|Atomic Boo]] receiving its own unique theme. Bowser's first battle in the Glitz Pit also uses a new theme instead of his overworld theme.
**The Peach intermissions have more unique music, such as a "stealth" theme when she is sneaking around in the Chapter 3 and Chapter 5 intermissions and a "tense" theme in certain moments that had no music in the original.
**Rogueport's theme features new arrangements for when Mario is within a shop, [[Podley's Place]], or (after completing chapter 5) the harbor. The ending montage with Goombella also features a unique arrangement of Rogueport's theme.
**A new tense theme plays as Cortez's ship blasts out of its cave and starts to engage the X-Naut ship, instead of Cortez's boss theme as in the original.
**When leveling up, there's a new jingle every ten levels corresponding to Mario's Rank improving.
**A melancholy theme was added to the scene where Koopie Koo she is worried about Koops leaving with Mario.
**A sentimental version of Koops's new theme plays when he reads the letter in Hooktail Castle.
**The terminals in the Glitz Pit that resemble the [[Game Boy Advance]] now make the sound of an actual GBA turning on when activated.
**Music plays when Mario and his partner lose to the Iron Clefts in the Glitz Pit.
**When Mario needs to find his way to the ring for the Rawk Hawk fight, a new dramatic theme was added.
**When Mario is reduced to a shadow during Chapter 4, three new, eerie ambient tracks play in place of the standard Twilight Town, Twilight Trail and Creepy Steeple themes.
**When talking to Professor Frankly at the end of Chapter 4, a new dramatic theme plays instead of Frankly's theme continuing to play like in the original game.
**When reading [[Ghost T.]]'s diary, a new horror track plays alongside it.
**The intro portion of Doopliss's theme music plays when he removes his [[Zip Toad]] disguise.
**A new, reworked rendition of an [[list of Paper Mario: The Thousand-Year Door pre-release and unused content#Music|unused track]] plays when exploring the back entrance and underground portions of Riverside Station. In the original game, the Riverside Station theme played in the former and no music played in the latter.
**A new variation of Bowser's theme plays when he swims back to Rogueport and during the post-Chapter 6 Bowser intermission, with the new theme being interrupted after Bowser breathes fire at Kammy Koopa and being replaced by Bowser's regular theme afterwards.
**During the ending sequence, the ringtone that plays when Mario receives Goombella's email is an arrangement of her new theme rather than the generic theme.
**The ending montage with Goombella features each partner's new theme rather than the standard music of each location.
**The credits theme has been replaced with an entirely new one incorporating leitmotifs from various tracks throughout the game.

====Sound effects====
*Sound effects are of a higher quantity and more characters have voice acting.
**Sound effects, particularly those of the [[Shadow Queen]], are not as synthesized as they were in the original game.
**In place of the sounds of message balloons appearing and disappearing, characters are now given unique talking sounds during dialogue, similar to the ''[[Mario & Luigi (series)|Mario & Luigi]]'' series and the ''Paper Mario'' series from ''Sticker Star'' onward. Notably, pre-established characters like [[Luigi]], [[Princess Peach]], [[Bowser]], and some [[Toad (species)|Toad]] NPCs (including [[Toadsworth]] and Toadette) have talking sounds sampled from their voices. Yoshi Kid and [[Kammy Koopa]] use talking sounds sampled from [[Yoshi]] and [[Kamek]]'s current voices, respectively.
***NPCs of other species that are standard to the ''Super Mario'' franchise use vocal effects from other games in which they appear. For example, [[Koopa Troopa]]s (including [[Koops]]), [[Thwomp]]s, and [[Bob-omb]]s (including [[Admiral Bobbery]]) speak with the vocal effects used for them since ''[[Super Mario 64]]''.<ref name=Direct/> [[Pianta]]s' vocal effects are taken from those in ''[[Super Mario Sunshine]]'', and [[Boo]]s' vocal effects are taken from those in ''[[New Super Mario Bros.]]'' [[Dull Bones]] also now use the standard vocal effects for [[Dry Bones]], although only when they are audience members.
***Characters of the same species can have variants in their speaking pitch. For example, [[Francesca]] speaks in a higher pitch than other Piantas, and Admiral Bobbery speaks in a lower pitch than most Bob-ombs.
**Audience members use voice clips of their respective species. Consequently, the audience's screams when leaving the theater in panic or when attacked by certain bosses are a lot quieter and barely audible.
**Mario's Hammer makes different sounds when hitting different surfaces, such as grass or paved paths. Objects reacting to Mario's hammer also create unique sounds, such as a crystalline chime from hitting the trees in Boggly Woods or organ music from hitting the organ in the storeroom of [[Creepy Steeple]].
**When the [[Boo]]s escape the box in Creepy Steeple, they can now be heard laughing.
**[[Chain Chomp]]s use their signature barking sound when they lunge at Mario on the overworld. Likewise, the "talking" [[Red Chomp]] of [[Chomp Country]] now uses a portion of said bark as its talking sound.
**Atomic Boo uses [[King Boo]]'s voice samples for its sound effects.
**Certain enemies and bosses—such as Bowser, Boos and Atomic Boo—make vocal sounds when they take damage in battle, similar to [[Magikoopa]]s and the [[Koopalings]] in ''[[Mario & Luigi: Superstar Saga + Bowser's Minions]]''.
**Flavio's "singing" during Chapter 5 is audible (performed by a kazoo). This kazoo sound effect is also added to the standard Keelhaul Key theme when Flavio briefly accompanies Mario in Chapter 5.
**Princess Peach's scream when being possessed by the Shadow Queen is audible.
**Mario makes no vocal sounds while he is a shadow during Chapter 4.
**Mario whistles in his sleep, similar to ''Paper Mario: The Origami King''.
*The sounds of the waves around Rogueport when reading Peach's letter in the intro are no longer present.
*There is a sound effect when the player presses A to start a chapter.
*When Mario stands on top of a [[plane panel]] or [[boat panel]], a sound effect reminiscent of [[Magic Circle]]s from ''Paper Mario: The Origami King'' can now be heard.<ref name=JP_Article>https://topics.nintendo.co.jp/article/aa63dd30-4bb8-4f17-83b9-a39e1d985fde</ref>
*There is now a sound effect when Mario uses [[Paper Mode]] to squeeze between two walls.<ref name=JP_Article/>
*The sound effect when enemies are defeated is now reminiscent of the one heard in ''Paper Mario: Sticker Star'' and ''Paper Mario: Color Splash.''
*The healing sound effect is the same as the one from ''[[Paper Mario: Sticker Star]]'' onwards.
*The sounds the coins make when collected are the same sound from ''[[Super Mario 3D Land]]'', just like in ''Paper Mario: The Origami King''.
*The spiked damage sound effect is the same as the one from ''Paper Mario: The Origami King''.
*There is a creaking sound effect when Mario hits the noose on the gallows in Rogueport from underneath.
*The [[Ground Theme (Super Mario Bros.)|Ground Theme]] and the [[Family Computer Disk System]] startup jingle are reused from the original console, rather than being rearranged like the original game.
*There are new sound effects for both moving on the field while riding on the Yoshi Kid and for using the Yoshi Kid's flutter jump on the field.
*The Three Shadows have a new sound effect for fading into or emerging from the shadows. Vivian's Veil also has a different sound effect when used to hide Mario in the field or in battle.
*When Peach is undressed during the Chapter 5 intermission, the sound of bare feet on tile can now be heard as she walks. In the original game, a quieter shuffling sound effect was used instead.
*The Excess Express's chime is a variant of its theme.
*Sound effects and chimes that were borrowed from stock sounds in the original game are original sounds.
*When activating a timed switch, such as the switches to enter Hooktail Castle, a timer sound effect was added in addition to the switches flashing.
*In the Path to Shhwonk Fortress, if Mario tries to open the closed doors, a rattling sound effect is now heard.
*When a fighter is rolled down on a stretcher outside of the minor league locker room in the Glitz Pit, the sound of rolling wheels was added.
*A sound effect was added when Mario tries to enter the Twilight Town pipe and it refuses his entry.
*In battles, the timing sound effects from some of Mario's hammer attacks, Flurrie's [[Dodgy Fog]], Vivian's [[Shade Fist]], and Bobbery's [[Hold Fast]] is an octave higher than in the original game. This sound effect is also no longer present in Yoshi Kid's [[Mini-Egg]] move.

===Miscellaneous===
;General
*A settings page is available in the menu list, allowing the ability to adjust the rumble and brightness settings and to exit to the title screen.
*The game's European and Japanese age ratings have been raised to PEGI 7 and CERO B, up from PEGI 3 and CERO A, respectively.
;Title screen
*Only Mario is present when the game is started for the first time. Mario's partners will each be added to the title screen when they join him, including Vivian, Admiral Bobbery, and Ms. Mowz, who were not present on the title screen of the original game.
**The color of the Yoshi Kid on the title screen matches the color of the Yoshi Kid obtained by the player rather than always depicting the Yoshi Kid as being colored green like in the original game.
**After Goombella joins the party, the curtains open earlier on the title screen.
**Peach, Bowser, and Kammy Koopa appear on the title screen after clearing their intermissions in Chapter 1.
**Purchasing and reading all of the [[Super Luigi (series)|Super Luigi]] books now results in Luigi appearing on the far left of the title screen.
**Confetti gets launched over the title screen after completing the game.
*The characters and the hills on the background are also animated.
*Like in ''Paper Mario: The Origami King'', any button can be used to start the game, whereas, in the original, only {{button|gcn|Start}} was used.
;Save files
*Save files can no longer be named, much like entries from ''[[Paper Mario: Sticker Star]]'' onward.
*On the file select screen, the player uses {{button|switch|Y}} to copy files and {{button|switch|X}} to erase them. File 1 and 4's colors have also been swapped, with 1 being blue and 4 being yellow.
*Save files depict Mario (including his alternate colors) and his current partner on the right of them and the date and time the game was last saved below it.
*Completing the game results in a medal appearing on the top left of the save file.
;Credits
*The credits have been overhauled to be modeled after a curtain call of a stage play, with the carousel of character silhouettes being replaced with the characters walking on the battle stage alongside various skits that occur during it. The credits end with a wide group shot of the major characters and the audience.
**Parakarry is the first character to appear in the credits rather than Luigi, who is an audience member instead.
*Copyright information is not present at the end of the credits.

Prior to the game's release, Nintendo of Europe e-mailed a survey about the role-playing games of the ''Super Mario'' franchise to a select number of newsletter subscribers.

==Descriptions==
;North American Nintendo eShop
<blockquote>'''''Join Mario on an epic paper-adventure to collect the Crystal Stars before the X-Nauts do!'''''

''The nefarious X-Nauts are after the treasure behind the Thousand-Year Door! With a map from Princess Peach, and the help of a few locals, Mario journeys through a colorful world made of paper to find them first. To prevail in this quest, you’ll have to level up Mario and his friends, master timing-based attacks and badges to impress the audience on the stage of combat, and make use of all the abilities that come with being cursed—er, conveniently made of paper—like folding into a plane to cross big gaps or turning sideways to slip through narrow openings.''

''Leaf through a storybook world with charming characters in every fold''

''Surprises abound in this deep and engaging tale, where everyone’s got something to say and it’s often not what you’d expect. Mario will meet all kinds of interesting folks on his journey, like the upbeat and studious Goombella and the shy but determined Koops. Some of these characters will need your help with their own quests, or even join your party. Others, like Peach and Bowser, have stories of their own that you’ll play between Mario’s chapters!''

''A classic turns the page, bringing fresh visuals and updated features''

''Twenty years after the original game on the Nintendo GameCube™ system, this version for the Nintendo Switch™ system has revamped graphics, and a suite of additional changes that make the game easier than ever to enjoy.''</blockquote>

==Pre-release and unused content==
Various badges that also went unused in the original game have graphics in this game, complete with a few having names. These include Mega Jump, Mega Quake, Mega Smash, Triple Dip, Triple Dip P, Lucky Day P, Pity Flower P, and unused alternate designs for Damage Dodge and Damage Dodge P. Interestingly, despite Triple Dip being unused, it is still mentioned in the patch notes for version 1.0.1.<ref>{{cite|title=''How to Update Paper Mario: The Thousand-Year Door''|url=https://en-americas-support.nintendo.com/app/answers/detail/a_id/65608/kw/paper%20mario|accessdate=July 9, 2024|publisher=Nintendo of America}}</ref>

==Glitches==
*Koops can now grab the Blue Key from the Jabbies early due to a glitch, which results in possible softlocks and glitched cutscenes.<ref name=Glitches1>[https://www.youtube.com/watch?v=gq7ors-icVo The TTYD Remake Has Some WEIRD Glitches...]</ref>
*By hammering Ms. Mowz or Goombella twice and have Mario distance himself from her and mashing the hammer while pressing {{button|switch|y}} to activate her ability, the player can freely move while her textbox is open. This leads to loading zone and cutscene triggers not working, camera glitching, crashes and more effects. A similar glitch can be used with flippable floor panels and Yoshi where the player can then ride Yoshi under the ground and travel out of bounds and using spring jump.<ref name=Glitches1/><ref>[https://www.youtube.com/watch?v=nA_TK7crxGs (ULTIMATE) fun and quirky things you can do in general :) | Paper Mario TTYD HD]</ref>
*The player can now duplicate badges by holding the maximum amount of badges and picking one up from the floor. Tossing a badge then picking it back up, the player still holds it. By then going to the [[Lovely Howz of Badges]] the player can buy the badge again, while holding the original one, thus cloning it. This works even for unique badges, including Simplifier, with really interesting effects if multiple are equipped at once.<ref>[https://youtu.be/Dcw9hLqGq4E You Can Clone ANY BADGE Now???]</ref>

==Staff==
{{main|List of Paper Mario: The Thousand-Year Door (Nintendo Switch) staff}}
Like ''[[Paper Mario: The Origami King]]'', the game was directed by Masahiko Nagaya and was art directed by Isamu Kamikokuryo. It was produced by Atsushi Ikuno, [[Taku Sugioka]], [[Risa Tabata]], and Shinya Saito, making this the first game in the series since the original game that [[Kensuke Tanabe]] did not serve as producer. However, he was given a special thanks credit. Tabata was previously an assistant producer on ''Paper Mario: Color Splash'' and ''Paper Mario: The Origami King''.

==Trivia==
*This is the second ''Super Mario'' game after ''[[Super Mario Odyssey]]'' to receive a B rating by the {{wp|Computer Entertainment Rating Organization|CERO}} in Japan.
*Despite being released in 2024, the copyright text on the bottom of the title screen and some promotional material only says 2004 for unknown reasons.
*Just like in [[Paper Mario: The Thousand-Year Door#Regional differences|the original game]], the intro to the title theme has a different melody if the system language is set to Japanese. The Nostalgic Tunes badge also accounts for this difference.
