Editing List of unreleased media

{{distinguish|[[tech demo]]s, which are rarely intended to be turned into commercial products, or [[pre-release and unused content]], elements from a game that are removed or altered before release}}
Due to various reasons (ranging from being of poor quality, developing a game for a failed or soon-to-be-discontinued system, or the company facing financial or legal woes), a project can end up being '''canceled''' and cease production. Despite their status, concepts present in canceled games and other media can be reused in commercial releases, and some canceled games are repurposed into different projects.

A game in development can also end up becoming '''{{wp|vaporware}}''', a term for projects that are announced and for which development is started, but for similar reasons, were never published.

The following is a list of ''[[Super Mario (franchise)|Super Mario]]'' media that has been canceled, or was never produced or released.

==Unreleased ports==
These games were planned ports of already existing ''Super Mario'' titles to different consoles, which went unreleased for various reasons.

===3DS version of ''[[Virtual Boy Wario Land]]''===
[[File:Virtual Boy Wario Land 3DS.png|thumb|The mockup]]
On December 15, 2013, independent developer Jools Watsham of {{wp|Renegade Kid}} posted a mockup of a colorized version of ''[[Virtual Boy Wario Land]]'' for the [[Nintendo 3DS]].<ref>{{cite|url=x.com/JoolsWatsham/status/412463614302240769|title=Curious to see how colored Wario Land Vitual Boy looks in 3D on your 3DS? Me too...|date=December 15, 2013|publisher=X|author=JoolsWatsham|accessdate=May 27, 2024|language=en}}</ref> In a 2016 episode of IGN's NYC podcast, Watsham revealed that he had made a formal pitch to Nintendo to make colorized versions of ''Virtual Boy Wario Land'' and Nintendo's other [[Virtual Boy]] games for the 3DS, but the pitch was rejected for unknown reasons.<ref>{{cite|author=IGN|date=April 02, 2016|url=www.youtube.com/watch?time_continue=639&v=OwpPhy0j3UA|timestamp=10:39|title=Mutant Mudds' Developer Made a Wario Demo - NVC|publisher=YouTube|accessdate=May 27, 2024|language=en}}</ref> He speculated this was because Nintendo did not want to remind people of the Virtual Boy, although Nintendo has referenced the Virtual Boy numerous times in newer games over the years.

===''Donkey Kong'' Arcade1UP products===
In 2018, a picture from the factory that produces Arcade1UP machines was leaked. This picture showed many previously unannounced models, one of which was ''[[Donkey Kong (game)|Donkey Kong]]''. This was likely a mock-up machine pitched to Nintendo, which ended up being rejected.<ref>Picture showing the Donkey Kong machine (5th from the right): [https://i.ytimg.com/vi/L1flEbriteE/maxresdefault.jpg]</ref>

At CES 2020, Arcade1UP demonstrated a miniature ColecoVision console, featuring a small "television set" as its screen. The console showed ''Donkey Kong'' running on its screen; oddly, it appeared to be playing the Famicom/NES version rather than the real ColecoVision port.<ref>{{cite|url=youtu.be/EcHsMsey2KM?t=1396|timestamp=23:16|author=Retro Ralph|publisher=YouTube|accessdate=May 27, 2024|date=January 7, 2020|language=en}}</ref> The console was never released, and is unclear if the product was ever officially approved; as many products at the booth were labeled as "pending licensor approval".

===''Donkey Kong'' for TRS-80===
In 1982, a port of ''Donkey Kong'' for the {{wp|TRS-80}} line of microcomputers was being developed by game designers Wayne Westmoreland and Terry Gilman. The port was eventually finished, but never received an official release as the duo could not get permission from Nintendo.

Later, in 1995, Westmoreland released all of their TRS-80 titles to the public domain, including the unreleased port of ''Donkey Kong''.<ref>http://www.trs-80.org/donkey-kong/</ref>

===''Donkey Kong 3'' for Mini Classics===
A planned [[Mini Classics]] version of ''[[Donkey Kong 3 (Game & Watch)|Donkey Kong 3]]'' was in the works, but never got released. In a stock image, it is mislabeled as ''Donkey Kong Junior''.<ref>{{cite|deadlink=y|archive=web.archive.org/web/20200806101145/https://www.forevergeek.com/get_nintendo_classic_games_on_your_keyring|title=Get Nintendo classic games on your keyring|date=August 5, 2009|author=Andy|publisher=Forever Geek|accessdate=May 27, 2024}}</ref>

===''Donkey Kong 3: Dai Gyakushū'' for FM-7===
An unknown video game company pitched an idea to Nintendo to port ''[[Donkey Kong 3: Dai Gyakushū]]'' to the {{wp|FM-7}}. They purchased the rights and produced it, but it went unreleased.<ref>{{cite|url=fm-7.com/museum/products/ma52bkgp|publisher=Oh!FM-7|language=ja|accessdate=May 27, 2024}}</ref>

===''Donkey Kong Jr.'' Coleco Tabletop (early version)===
The tabletop arcade version of ''[[Donkey Kong Jr. (game)|Donkey Kong Jr.]]'' by {{wp|Coleco}}, released in 1983, was a rebranded version of the [[Donkey Kong Jr. (Game & Watch)|Game & Watch Tabletop]] version. However, early promotional images show a machine more in line with Coleco's other tabletops, with a completely different port than the released model (which looks closer to the original arcade game).<ref>Pre-release image showing the early machine w/ screenshot: [https://www.picclickimg.com/d/w1600/pict/123630864158_/Coleco-Perma-Power-Adapter-Sealed-w-Donkey-Kong.jpg]</ref> A mock-up machine has been found, but it contained the original ''Donkey Kong'' inside.<ref>{{cite|deadlink=y|archive=web.archive.org/web/20100123192155/http://www.geekvintage.com/coleco-tabletop-donkey-kong-jr-hardware.php|title=Donkey Kong Jr Coleco Tabletop Arcade - Model 2398X|publisher=Geek Vintage|accessdate=May 27, 2024}}</ref>

===''Donkey Kong Jr.'' for BBC Micro===
A port of ''Donkey Kong Jr.'' for {{wp|BBC Micro}} by {{wp|Atarisoft}}, who also developed the {{wp|Atari 8-bit family|Atari 8-bit}} port, was created but ultimately unreleased.<ref>{{cite|url=www.youtube.com/watch?v=DNKgk68RirA|author=Highretrogamelord|date=March 8, 2018|publisher=YouTube|language=en|accessdate=May 27, 2024}}</ref>

===Enhanced ''Donkey Kong'' and ''Donkey Kong Jr.'' ColecoVision ports===
In the early 2000s, incomplete prototype versions of ''[[Donkey Kong (game)|Donkey Kong]]'' and ''[[Donkey Kong Jr. (game)|Donkey Kong Jr.]]'' for {{wp|ColecoVision}} were discovered. Both cartridges actually postdated the ColecoVision releases and were seemingly ports of the versions from the {{wp|Coleco Adam}} computer, which featured more levels and cutscenes. The games were re-compiled into hacked ROMs titled "Super DK!" and "Super DK Junior" respectively; the unaltered ROMs were never released.<ref>{{cite|url=www.digitpress.com/reviews/superdonkeykong.htm|title=''Super Donkey Kong''|publisher=Digital Press Online|language=en|accessdate=May 27, 2024}}</ref><ref>{{cite|url=forums.atariage.com/topic/219923-super-donkey-kong|title=Super Donkey Kong - ColecoVision / Adam|publisher=AtariAge Forums|language=en|accessdate=May 27, 2024|date=December 20, 2013}}</ref>

===''Famicom Mini Collection''===
{{main|Classic NES Series#Famicom Mini Collection}}
A multicart of [[Family Computer]] games ported to the [[Game Boy Advance]], planned to be released in China by [[iQue]]. It featured ''Mario Bros.'', ''Super Mario Bros.'', ''Wrecking Crew'', ''Dr. Mario'', ''Donkey Kong'', and ''Super Mario Bros. 2'' (Japan), in addition to ''Clu Clu Land'', ''Ballon Fight''{{sic}}, ''Metroid'', ''Excite Bike'', and ''Ice Climber''.

===''Game & Watch-e''===
[[File:Game-watch-gallery-e-package.jpg|thumb|100px|Planned card packaging]]
As early as the North American launch of the [[e-Reader]], Nintendo had unveiled plans to release a series of [[Game & Watch]] cards for the e-Reader device. However, the only card ever released was a promotional card for ''[[Manhole (Game & Watch)|Manhole]]'' (bundled in with the e-Reader itself), with the full set never being produced. The card packs, officially titled ''Game & Watch-e'' or ''Game & Watch-e Collection'', were to feature three versions of games: classic, color, and collector. The classic versions were the original games, while the color versions were similar to the "Modern" modes in the ''Game & Watch Gallery'' series (featuring the ''Super Mario'' characters). The exact details of the collector versions remain unknown, though the card packaging artwork showcases it with a black-and-white Luigi.

The game ports appear to be unique from ''[[Game & Watch Gallery 4]]''; a few advertisements show a screenshot of the color version of ''[[Fire]]'', which has a more basic background (e.g. the grass and sky) compared to the Modern ''Gallery 4'' version. Additionally, a few advertised games did not receive other Game Boy Advance ports at all; namely, ''[[Spitball Sparky]]'' and the color version of ''[[Vermin]]'' (featuring Yoshi).<ref name="nintendo-world-report">{{cite|url=www.nintendoworldreport.com/forums/index.php?topic=32861.0|date=December 2, 2010|title="Game and Watch-e: What was meant to be"|publisher=Nintendo World Report|accessdate=May 27, 2024|language=en|author=UncleBob}}</ref>

In an August 2003 brochure from Walmart, it was stated that the cards were planned to launch in October of that year. The short release window implies that the ''Game & Watch-e'' line was effectively completed before it was abruptly canceled.<ref name="nintendo-world-report" /> Its cancelation was most likely due to the failure of the e-Reader on the North American market, though no official reasoning is known.

===''Mario Bros.'' Apple II port===
''Mario Bros.'' was ported to the {{wp|Apple II}} in 1984 by {{wp|Atari}}, but was never officially released. Despite this, its code was leaked (possibly by an actual Atari employee) and was widely distributed in the 1980s via piracy.<ref>https://twitter.com/forestillusion/status/1005351467085991936</ref>{{dead link}} There was even a bootleg Russian arcade version of ''Mario Bros.'' based on the Apple II prototype known as ''Kuzmich-Egorych'' (''Кузьмич-Егорыч'').<ref>{{cite|url=adb.arcadeitalia.net/dettaglio_mame.php?game_name=kuzmich|title=Kuzmich-Egorych - MAME machine|publisher=Arcade Italia|accessdate=May 27, 2024}}</ref>

===''Mario Bros.'' Atari 8-bit port (1984 version)===
In 1984, Atari planned to release ''[[Mario Bros. (game)|Mario Bros.]]'' for their Atari 8-bit computer line (400/800/XL/XE). This port was identical to the previously released Atari 5200 version of the game. For unknown reasons, the game was canceled despite being fully finished. ''Mario Bros.'' would eventually receive an Atari 8-bit release in 1988, but this port was completely different than the 1984 prototype.<ref>{{cite|deadlink=y|archive=web.archive.org/web/20060210034217/http://www.atariprotos.com/8bit/software/mariobros/mariobros.htm|title=Mario Bros.|publisher=AtariProtos.com|accessdate=May 27, 2024}}</ref> 

===''Mario Bros.'' Commodore 64 port (1984 version)===
Yet another ''Mario Bros.'' port that went unreleased was the {{wp|Commodore 64}} version, once again planned for a 1984 release. This version was to have been published by Atari, but was developed by two programmers from Designer Software.<ref>{{cite|url=games.greggman.com/game/atarisoft-mario-bros-c64|title=Atarisoft Mario Bros for Commodore 64|publisher=games.greggman.com|accessdate=May 27, 2024|language=en}}</ref><ref>{{cite|quote=...my friend Gregg Tavares and I created (from scratch) for the Commodore 64 for Atarisoft (indirectly through a company called Designer Software)|url=www.youtube.com/watch?v=FCtYtrTLR28|date=August 23, 2008|title= Mario Bros - Commodore 64 (comments section)|publisher=YouTube|accessdate=May 27, 2024}}</ref> A completely different (and rather bizarre) port for the Commodore 64 would later be released by Ocean in 1987.<ref>{{cite|url=www.youtube.com/watch?v=N5-lBLXDh78|title=<nowiki>[Longplay]</nowiki> Mario Bros, phase 1-10 (Ocean) - Commodore 64|date=April 20, 2018|publisher=YouTube|accessdate=May 27, 2024}}</ref>

===''Mario Party'' and ''Mario Party 2'' for 64DD===
The first two ''[[Mario Party (series)|Mario Party]]'' games were among many announced titles for the [[Nintendo 64DD]],{{ref needed}} but the peripheral was a commercial failure. This resulted in all ''Super Mario'' games for the system being canceled, except for four ''[[Mario Artist (series)|Mario Artist]]'' games.

===Other Atarisoft computer ports===
In several magazine publications, an advertisement from Atari was run stating that ''Mario Bros.'' and ''Donkey Kong Jr.'' would release for the Commodore 64, IBM PC (DOS), and Apple II. None of these ports were ever released, but as aforementioned, the Apple II and Commodore 64 versions of ''Mario Bros.'' have been found. The flyer also lists several never-released ports of ''Crystal Castles'', ''Typo Attack'', and ''Track & Field''.<ref>{{cite|url=66.media.tumblr.com/9f004219a5401ccf315bf744d84fd790/tumblr_puvhrau9Nl1tg94xho1_1280.jpg|title=Atarisoft ad|publisher=OLD VIDEO GAME ADVERTISEMENTS|accessdate=May 27, 2024}}</ref>

According to [https://www.digitpress.com/faq/atarisoft.htm The Atarisoft FAQ], the following ports were also planned:

===Super Game Module ''Donkey Kong'' games===
The Super Game Module was a canceled peripheral for the ColecoVision, which took unique cartridges.

In mid-1987, {{wp|Telecomsoft#Firebird|Firebird}} developers Gary Liddon and Gary Penn developed a recreation of [[World 1-1 (Super Mario Bros.)|World 1-1]] from ''Super Mario Bros.'' in the Commodore 64. The demo received interest from Colin Fuidge, who pitched it to Nintendo. However, Nintendo responded by sending legal threads, causing the pitch's cancelation.

===''Super Mario Bros. 3'' id Software pitch===
In 1990, in its infancy, video game company {{wp|id Software}} developed a demo for the {{wp|IBM Personal Computer|IBM PC}} titled ''Dangerous Dave in Copyright Infringement'', which was a recreation of the first level of ''[[Super Mario Bros. 3]]''.<ref>{{cite|url=www.youtube.com/watch?v=cj4HJkeQSg0|title= Dangerous Dave In Copyright Infringement ⭐ Unreleased Prototype|author=CuteFloor|publisher=YouTube|date=January 12, 2008|accessdate=May 27, 2024}}</ref> It was then decided to rework the demo into an actual port of ''Super Mario Bros. 3'' for PC; the game was then pitched to Nintendo, which they ended up rejecting.

==Low-information media and rejected pitches==
This section lists rejected pitches (meaning ideas proposed internally or to Nintendo without seriously going into production) and canceled projects, most of which have too little information to warrant their own pages.

====Boss Game Studios' ''Super Mario'' game pitch====
[[File:Boss game studios concept art.jpg|thumb|left|150px|The concept art]]
Sometime during the late '90s, {{wp|Boss Game Studios}} pitched a ''Super Mario'' game to Nintendo of America. The only known proof of its existence is a storyboard, drawn by Patrick Michael Clark, bought in an online auction showing [[Mario]] stepping on a wooden plank, following by the wooden plank sprouting legs and walking in Mario's direction. According to a Boss Game Studios employee, "''The Mario thing I think was for a proposal. I’m not sure if we were trying to get the license from Nintendo to produce a Mario game, or if they approached us to do one.

====CD-i ''Donkey Kong'' game====
A [[Donkey Kong (series)|''Donkey Kong'' game]] was in development for the [[Philips CD-i]]. The game was revealed in the [http://www.linkedin.com/in/adrianjonesgames LinkedIn resume] of programmer Adrian Jackson-Jones, which states that it was in development during the 1992-1993 period at Riedel Software Productions. Jackson-Jones "designed and implemented the game engine" for the project;<ref>{{cite|deadlink=y|archive=web.archive.org/web/20190718105126/http://cdii.blogspot.com/2010/12/rsp-say-they-worked-on-donkey-kong-on.html|title=RSP say they worked on Donkey Kong on CD-i|publisher=Interactive Dreams|date=December 13, 2010|accessdate=May 27, 2024}}</ref> Jackson claims he worked on the game alongside programmer [https://www.linkedin.com/in/owen-flatley-2552083a Owen Flatley] and that he has no surviving assets left of the game. These claims were corroborated in an investigation by ''Time Extension'' writer John Szczepaniak, who contacted both Jackson-Jones and Riedel Software Productions founder Michael J. Riedel. Riedel stated that the company had a habit of junking canceled projects' assets, while Jackson-Jones was able to confirm his involvement in spite of a memory disorder, stating that he still recalled the experience of programming the game. According to Jackson-Jones, a prominent challenge during development was the limited memory of the CD-i, which he overcame by only loading in on-screen elements based on the player's movement.<ref>{{cite|url=www.timeextension.com/features/like-zelda-and-mario-donkey-kong-was-supposed-to-get-a-philips-cd-i-game-what-happened|title=Like Zelda And Mario, Donkey Kong Was Supposed To Get A Philips CD-i Game - What Happened?|author=Szczepaniak, John|date=July 29, 2023|publisher=Time Extension|accessdate=May 27, 2024}}</ref>

According to a Riedel Software Productions artist, the game would have been a branching side-scroller similarly to ''[[Donkey Kong Country]]''. However, due to the limitations of the CD-i and issues with Philips, development did not progress past the storyboarding phase.<ref name=DYKGRumors />

====''DDR MARIO 2''====
According to a leaked internal Nintendo spreadsheet, a game labeled as '''''DDR MARIO 2''''' - presumably an abbreviation for '''''Dance Dance Revolution Mario 2''''' - was planned to be released on the Wii. The game was to be developed by [[Konami]]. However, the document mentions that development had not started yet; it may have never gotten past the concept stages.<ref>{{cite|url=www.resetera.com/threads/update-super-mario-64-and-oot-source-leaked-massive-nintendo-data-leak-source-code-to-yoshis-island-a-link-to-the-past-f-zero-and-more.254724/page-79?post=69882678#post-69882678|title=UPDATE: Super Mario 64 and OoT Source Leaked, Massive Nintendo Data Leak...Source Code to Yoshi's Island, A Link to the Past, F-Zero and more|publisher=ResetEra|accessdate=May 27, 2024}}</ref>{{better source}}

''Diddy Kong Racing Adventure'' was a pitched sequel to ''Diddy Kong Racing'' being developed by {{wp|Climax Group|Climax}}. It was never announced to the public in any capacity and only became known after an amateur video game archivist acquired the prototype and published a video about it in November 2016.<ref>{{cite|url=www.youtube.com/watch?v=j6d5IbpzFtw|title= Diddy Kong Racing Adventure : The Undeveloped Gamecube Racer|author=PtoPOnline|date=November 9, 2016|publisher=YouTube|accessdate=May 27, 2024}}</ref>

====''Donkey Kong IV''====
'''''Donkey Kong IV''''' is a rumored final title in the original ''Donkey Kong'' series. The game is stated to have only been test-marketed in arcades, never getting a full release. It was only ever reported in issue #13 of {{wp|Mean Machines}} magazine (October 1991), and was possibly the result of a misconception or confusion for another game (a likely candidate being Ocean's ''{{wp|Kong Strikes Back!}}'').<ref>{{cite|url=x.com/retrogamegeeks/status/859415398772596736|publisher=X|title=SUPER MARIO BROS. 3: Here's the Oct 1991 Mean Machines review & 4 page history of Mario feature #retrogaming #Nintendo #Mario #NES #gaming|date=May 2, 2017|accessdate=May 27, 2024|language=en}}</ref>

====''Donkey Kong Country 4''====
According to Rare employee Paul Rahme, it was internally suggested at Rare to make a new ''Donkey Kong Country'' game for the [[Nintendo DS]], tentatively named '''''Donkey Kong Country 4''''', as remaking the trilogy for the [[Game Boy Advance]] gave the developers experience and a good basis for making a sequel. The pitch ended up not getting much traction internally and was dropped.<ref>{{cite|date=October 7, 2011|url=www.dkvine.com/?p=1654|title=Donkey Kong Country 4: Here Comes [REDACTED PUN<nowiki>]</nowiki>!|publisher=DK Vine|accessdate=May 27, 2024}}</ref><ref>{{cite|deadlink=y|archive=web.archive.org/web/20111221071415/http://www.dkvine.com/features/stamped_dkcgba.html|title=The Donkey Kong Country GBA Trilogy|author=Matt, Chad|publisher=DK Vine|accessdate=May 27, 2024}}</ref>

====''Freedom''====
After the release of ''[[Skylanders: SuperChargers]]'' in 2015, {{wp|Blizzard Albany|Vicarious Visions}} started development on a pitch for a [[Nintendo Switch]] game directed by founders Guha and Karthik Bala.<ref name=Freedom>{{cite|author=DidYouKnowGaming|date=May 4, 2024|url=www.youtube.com/watch?v=KJlu9g8UEAI|title=Donkey Kong's Lost 3D Platformer & The Decay of Activision Blizzard|publisher=YouTube|accessdate=May 4, 2024}}</ref> The pitch, codenamed '''''Freedom''''', was a prototype for a ''Donkey Kong'' platformer set in an open island and focused on movement and flow featuring wall climbing and vine swinging, as well as a new grinding mechanic on sloped vines using banana peels inspired by the studio's past work on the ''{{wp|Tony Hawk's}}'' series and ''{{wp|Jet Grind Radio (Game Boy Advance video game)|Jet Grind Radio}}'' for the Game Boy Advance.<ref name=Freedom />

''Freedom'' would have featured a very different art style compared to past ''Donkey Kong'' games and ''Skylanders: SuperChargers'', where Donkey Kong would have had "{{wp|Tim Burton|Burton}}-esque" exaggerated proportions with big arms and small legs. Another planned setting for the ''Freedom'' prototype was a jungle-infested city, in which Donkey Kong would have had to climb up to upper areas by interacting with objects and building up momentum.<ref name=Freedom />

Despite receiving interest from Nintendo, Vicarious Visions' parent company {{wp|Activision}} canceled the game in spring 2016 to receive additional development for their major franchises.<ref name=Freedom /> The game's cancelation would be one of the reasons for the Bala brothers' departure from the company and founding of [[Velan Studios]],<ref name=Freedom /> which would later collaborate with Nintendo to develop ''[[Mario Kart Live: Home Circuit]]''.

====''Mario Factory''====
[[File:Mario Factory.jpg|thumb]]
In 1994, a Nintendo patent was created for a device that could create basic games for the SNES, likely intended for use in schools.<ref>{{cite|url=patents.google.com/patent/US6115036?oq=inassignee:"Nintendo+Co+Ltd"|title= Video game/videographics program editing apparatus with program halt and data transfer features|publisher=Google Patents|accessdate=May 27, 2024}}</ref> The program for creating said games was titled '''''Mario Factory''''', and featured loose adaptions of the ''Super Mario'' characters.<ref>{{cite|url=patentimages.storage.googleapis.com/4b/1a/bf/29a5fe6c45bf11/US6115036-drawings-page-9.png|title=''Mario Factory'' image|publisher=Google Patents|accessdate=May 27, 2024}}</ref> It is known that the patented machine itself had been released in Japan at some point, being used with the "Game Processor RAM Cassette".<ref>{{cite|url=x.com/luigiblood/status/1109479153747804160|title=Do you guys remember the Mario Factory patent? <nowiki>https://</nowiki>patents.google.com/patent/US6115036A/en Well thanks to the recent Satellaview uploads: We know it exists in some shape or form, it was called the "Game Processor".

====''Mario Motors''====
[[File:Mario Motors.jpg|thumb|left]]
'''''Mario Motors''''' was a pitch made by game designer {{wp|Yoot Saito}} for a [[Nintendo DS]] game. The game had players "''shaving and sculpting out of a chunk of metal to make a cylinder [which then] decides the ability of your engines.''". Saito also considered having the player blow in the DS's microphone to "''learn how acceleration works''" but scrapped it because the mechanic could have been too demanding for children. Despite initial interest from both [[Satoru Iwata]] and [[Shigeru Miyamoto]], the project never got off the ground with Saito stating, "''I can’t tell you why, but please guess.''"<ref>{{cite|author=Devore, Jordan|date=April 21, 2018|url=www.destructoid.com/yoot-saito-worked-on-mario-motors-a-canceled-ds-game-about-building-engines|title=Yoot Saito worked on Mario Motors, a canceled DS game about building engines|publisher=Destructoid|accessdate=May 27, 2024}}</ref>

====Retro Studios' Boo pitch====
[[File:Project Haunt.jpg|thumb|left]]
From 2006 to 2007, [[Retro Studios]] developed a game for the [[Nintendo DS]] tentatively named ''The Blob Game'', in which the player controlled a blob that had to be flung using the touch screen. A pitch for the game featuring [[Boo]]s was created, which included artwork that was later posted online by former Retro Studios artist Sammy Hall.<ref name=RetroStudios>{{cite|author=DidYouKnowGaming|date=November 4, 2023|url=www.youtube.com/watch?v=4i7P9nbOTvA|title=8 Cancelled Nintendo Games from Retro Studios (New Discoveries)]|publisher=YouTube|accessdate=November 4, 2032}}</ref> The Boo art includes sketches titled “possession powers” depicting a [[capture]]-like gameplay mechanic and new witch creatures called “Broomies”, alongside a potential world map. One sketch titled “Deep in debt at Haunt University” seems to depict a storyline involving a professor version of [[King Boo]].

'''''Super Donkey''''' was a ''[[Donkey Kong (franchise)|Donkey Kong]]'' game for the SNES. In July 2020, a large amount of Nintendo-related source code and prototypes were leaked to the public. Among this leak was the source code to ''[[Super Mario World 2: Yoshi's Island]]'', which included many prototypes that were greatly different from the final product. However, two files are so early that they have virtually no connection to the game at all - "''super_donkey_1''" and "''super_donkey_2''". These games presumably served as the basis of what became ''Yoshi's Island'', though most elements of ''Super Donkey'' were eventually scrapped.<ref>{{cite|author=Sebastian|date=July 24, 2020|url=www.youtube.com/watch?v=Rrhkv47Vdag|title=Super Nintendo Leaked Demos - super_donkey_1.bin|publisher=YouTube|accessdate=May 27, 2024}}</ref> Among the recognizable elements are [[Melon Bug]]s, apes that may be an early version of [[Ukiki|Grinder]]s, and a dog enemy that may have been the inspiration for [[Poochy]].<ref>{{cite|author=Sebastian|date=July 24, 2020|url=www.youtube.com/watch?v=B3IShS_ThPI|title=Super Nintendo Leaked Demos - super_donkey_2.bin|publisher=YouTube|accessdate=May 27, 2024}}</ref>

At first glance, the game itself features a generic protagonist and no connection to Mario. However, various graphic scratchpads (scattered across other files) confirm that at some point, the game starred Mario, with Donkey Kong appearing as well. This strongly implies that the game was originally a ''Donkey Kong'' title, which was never formally announced or shown to the public.

====''Super Mario''/''Rabbids'' crossover adventure game====
[[File:Scrapped rabbids crossover.jpg|thumb|left]]
In 2010, [[Ubisoft]] Paris had explored proposing a crossover between the ''Super Mario'' franchise and its own ''{{wp|Raving Rabbids|Rabbids}}'' franchise.<ref>{{cite|author=Robertson, Liam|date=June 12, 2017|url=www.youtube.com/watch?v=21oZewbY0j4|title=Mario + Rabbids: The Lost Adventure Game Concept|publisher=YouTube|accessdate=May 27, 2024}}</ref> The game was conceptualized as a "subversive, self-aware take" on the ''Super Mario'' franchise and concept art was produced depicting [[Rabbid]]s kidnapping [[Bowser]] as [[Mario]] chases them. According to an anonymous Ubisoft employee, the pitch was possibly rejected by Nintendo before it was formally shown. According to Ubisoft employee Davide Soliani, this rejected pitch is unrelated to the released ''[[Mario + Rabbids (series)|Mario + Rabbids]]'' series.<ref>{{cite|url=x.com/DavideSoliani/status/890940460587462656|title=Not at all 😂 (in response to Super Mario Wiki)|author=Soliani, Davide|publisher=X|accessdate=May 27, 2024}}</ref>

====''Super Mario'' American football game====
During the early years of [[Retro Studios]], plans were underway for an American football game featuring Mario for the GameCube. At the request of Nintendo, the project was reworked early on to turn it into a generic, realistic football game (known as both ''NFL Retro Football'' and ''Retro Studios Football''). Its Mario-less incarnation was ultimately canceled as well, reportedly due to the release of ''{{wp|Madden NFL 2002}}'' on the GameCube.<ref name=RetroStudios /><ref>{{cite|url=www.unseen64.net/2008/04/08/football-retro-studios-gc-tech-demo|title=Retro Studios Football|date=April 8, 2008|author=Robertson, Liam|publisher=Unseen64|accessdate=May 27, 2024}}</ref>

====''Super Yoshi no Tamago''====
[[File:Super Yoshi no Tamago Title.png|thumb|The title screen of ''Super Yoshi no Tamago'']]
In October 2024, a large amount of assets and source code from [[Game Freak]] were leaked to the public.<ref>{{cite|author=Welsh, O.|date=October 14, 2024|url=https://www.polygon.com/news/465710/pokemon-game-freak-leak-hack|title=Pokémon developer Game Freak suffers massive data leak|publisher=Polygon|accessdate=October 14, 2024}}</ref> Specifically, the leaked source code to ''{{iw|bulbapedia|Pokémon Black and White Versions|Pokémon Black and White}}'' includes an unreleased and unfinished build for a ''[[Yoshi (game)|Yoshi]]'' sequel or remake titled '''''Super Yoshi no Tamago''''' (スーパーヨッシーのたまご, lit.

===={{wp|Tesla}} ''Mario Kart'' game====
According to {{wp|Elon Musk}}, a ''[[Mario Kart (series)|Mario Kart]]'' game that would be played on Tesla vehicles was proposed to Nintendo. Nintendo did not give them a license.<ref>{{cite|author=Lanier, Liz|date=November 30, 2018|url=variety.com/2018/gaming/news/elon-musk-mario-kart-for-teslas-1203063715|title=Elon Musk Claims Nintendo Wouldn’t License ‘Mario Kart’ for Teslas|language=en|publisher=Variety|accessdate=March 25, 2019}}</ref> 

====''VB Mario Kart''====
The German magazine ''Big N'' claimed that a Virtual Boy installment of the ''Mario Kart'' series, tentatively named '''''VB Mario Kart''''', was in development.<ref>{{cite|title=''Big N'' magazine|language=de|date=July-August 2000|page=[[Media:Big N Magazine (Germany) VB.jpg|19]]}}</ref> The only known media report of it is Big N's August 2000 issue, which listed it among various other canceled Virtual Boy projects. As such, ''VB Mario Kart'' ended up being canceled due to the discontinuation of the Virtual Boy for its poor sales.

====''Wario Pool''====
[[File:Scrapped wariopool intro.gif|thumb|left|The mockup]]
'''''Wario Pool''''' is a canceled rework of the 2001 Game Boy Color billiards game ''{{wp|3D Pocket Pool}}''. Developer {{wp|Nick Pelling}} wanted to rework the game into a ''[[Wario (franchise)|Wario]]'' game during development after it was not receiving any attention despite his efforts, so he decided to reach out to [[Nintendo]] to rework the game with [[Wario]] as the main character. The pitch was ultimately rejected, so ''3D Pocket Pool'' released as originally planned.<ref>{{cite|author=Nick Pelling|title=''Retro Gamer'' issue #26|page=84}}</ref> Pelling later posted the mock-up introduction to the game on his website.<ref>[https://www.nickpelling.com/wariopool.gif''Wario Pool'' intro]</ref>

The introduction begins with Wario sitting in his castle watching sports news. Suddenly, he receives a phone call asking him whether he will compete in the big pool competition the next day. Wario responds by saying that he would not, as he does not need any more worthless victories. He then looks at the television and sees sharks that have swum into his town and become competitors in the tournament, who then brag about how they will win and taunt Wario. Wario becomes mad and tells the man on the phone he does actually need one more trophy for his collection before preparing to "shoot some pool."

====''Yoshi Racing''====
'''''Yoshi Racing''''', or '''''Yoshi Racers''''',<ref name=DYKGRumors /> was a rejected pitch for a 3D game in the ''[[Yoshi (franchise)|Yoshi]]'' franchise. The game was revealed in an article by ''{{wp|Eurogamer}}'' detailing [[Argonaut Games]]' involvement in the development of ''[[lylatwiki:Star Fox (game)|Star Fox]]''<ref name="Eurogamer">{{cite|url=www.eurogamer.net/born-slippy-the-making-of-star-fox|date=June 22, 2014|title=Born slippy: the making of Star Fox|publisher=Eurogamer|language=en|author=McFarren, Damien|accessdate=May 27, 2024}}</ref> where the game was described as a 3D platformer and left unnamed, while a message board post by an Argonaut employee named the game "''Yoshi Racing''" and described it as a character racing game.<ref name="NeoGaf">{{cite|author=inpHilltr8r|date=December 29, 2016|url=www.neogaf.com/threads/larry-bundy-jr-4-times-shigeru-miyamoto-was-an-asshole.1328992/page-8#post-227362239|Post on NeoGAF|publisher=NeoGAF}}</ref>

According to Argonaut Games employee Nic Cusworth in an interview from the book ''The Minds Behind Adventure Games'', during the end of ''{{wp|Creature Shock}}''{{'}}s development in 1994, an animator created two test animations on PC featuring colored Yoshis racing in an obstacle course.<ref name=DYKGRumors /> Following this, Argonaut's Jez San went to [[Nintendo]] to pitch the idea,<ref name=DYKGRumors /> but they did not follow on the offer, with San speculating this was because the company did not want to let third-parties use its characters.<ref name="Yoshi">{{cite|author=San, Jez|quote=The end came when we pitched to do a 3D platform game, the likes of which had never been done before. We mocked up a prototype using Yoshi. It was essentially the world's first 3D platform game and was obviously a big risk - Nintendo had never let an outside company use their characters before, and weren't about to, either. This is the moment the deal fell apart.}}</ref> After this setback, Argonaut decided to retool the pitch into an original IP, ''{{wp|Croc: Legend of the Gobbos}}''.

Jez San believes that the refusal to pick up the ''Yoshi'' pitch was the final blow to Nintendo and Argonaut's relationship, which was previously damaged by the cancelation of the nearly completed ''[[lylatwiki:Star Fox 2|Star Fox 2]]''.<ref name="Yoshi"/><ref name="Apology">{{cite|author=San, Jez|quote=Miyamoto-san came up to me at a show afterwards and apologized for not doing the Yoshi game with us and thanked us for the idea to do a 3D platform game. He also said that we would make enough royalties from our existing deal to make up for it. That felt hollow to me, as I'm of the opinion that Nintendo ended our agreement without fully realizing it. They canned Star Fox 2 even though it was finished and used much of our code in Star Fox 64 without paying us a penny.}}</ref> San further claims that the prototype influenced ''[[Super Mario 64]]'', stating that ''"[[Shigeru Miyamoto|Miyamoto-san]] went on to make Mario 64, which had the look and feel of our Yoshi game - but with the [[Mario]] character, of course"''. Jez San also recalls an occurrence where Shigeru Miyamoto came to him and apologized for not picking up the ''Yoshi'' game.<ref name="Apology"/>

====Sony Pictures ''Super Mario'' film====
Internal emails leaked to the public by proxy of the 2014 {{wp|Sony Pictures hack}} detailed negotiations between {{wp|Avi Arad}} and Nintendo to have {{wp|Sony Pictures}} produce a ''Super Mario'' movie. The email exchange between Avi Arad and Sony Pictures executive {{wp|Amy Pascal}} showed photos of Arad meeting with [[Shigeru Miyamoto]] and [[Satoru Iwata]]; Pascal would later forward one of the emails to another executive with the comment "Avi closed Mario brothers" (Arad would later state to the press the deal had in fact not been closed after the emails were made public by the hack).<ref>{{cite|auhtor=Vary, Adam B.|date=December 11, 2014|url=www.buzzfeednews.com/article/adambvary/sony-nintendo-mario-bros-movie|title=Movie Rights From Nintendo, Leaked Emails Show|publisher=Buzzfeed|accessdate=May 27, 2024}}</ref> Although no information beyond what is found in the leaked emails was made public, it seems the talks for ''Super Mario'' broke down, as Nintendo would officially announce in 2018 that [[The Super Mario Bros.

Comic book publisher {{wp|Archie Comics}} (which has published other comics based on famous video game properties including ''{{wp|Sonic the Hedgehog (comic series)|Sonic the Hedgehog}}'' and ''{{wp|Mega Man (Archie Comics)|Mega Man}}'') pitched a ''Super Mario'' comic book series to [[Nintendo]], but it was rejected, as confirmed by writer {{wp|Ian Flynn}}.<ref>{{cite|author=rawmeatcowboy|date=November 2, 2015|url=www.gonintendo.com/stories/245998-archie-pitched-nintendo-a-super-mario-comic-but-it-was-shot-down|title=Archie pitched Nintendo a Super Mario comic, but it was shot down|publisher=Go Nintendo|accessdate=May 27, 2024}}</ref> The concept art for the pitch was drawn by Archie artists {{wp|Tracy Yardley}} and Ben Bates.

To this end, artist Richard Elson and writer Nigel Kitching produced a mock-up,  featuring a cover and a short story showing Mario and Luigi arriving in the [[Mushroom Kingdom]], fighting [[Koopaling]]s and [[Boo]]s, coming to face with a monstrous [[Donkey Kong Jr.]], and finally escaping in a [[Warp Pipe]]. Nintendo ultimately passed over the idea after taking multiple years to make a decision<ref name="UltimateFrieza"/>

Reflecting on the comic, an unnamed source explained that Nintendo was a more "regulated" and "hands-on" company than [[Sega]] and that having to wait for approval for a regular publication such as a comic would have been a "nightmare."<ref name="UltimateFrieza"/>

====Kinoppe spin-off manga====
In the author notes of his self-published ''doujin'' book ''Kinoppe-Chan Forever vol 2'', the author of [[Super Mario (Kodansha manga)|Comic BonBon's ''Super Mario'' manga]], Kazuki Motoyama, states that a former editor had pitched him a spin-off manga starring  the manga's mascot character [[Kinoppe]]. These plans were halted when Nintendo unexpectedly pulled ComicBonBon's Mario manga license in 1997.
