List of Game & Watch Gallery 4 pre-release and unused content

This is a list of pre-release and unused content for the game Game & Watch Gallery 4.

Early builds

Several pre-release screenshots show that the game elements were very different from those seen in the final product.

Pre-release image	Name	Description	Final release image
	Title Screen	The title screen of the game showed many differences to the final version. Ignoring the Japanese text, the hatched Yoshi Egg and Koopa Troopa were closer together, the Goonie was larger, and there was no black crow present in the top left corner. There is also no bar at the bottom that reads "©1980–2002 Nintendo."
	Game Select	Of all the changes seen above, the Game Select screen has likely to have changed the most. The background was purple and the "Game Select" logo was larger. The Modern/Classic box was made blue and was given corners rather than round edges. When a game was selected, the game logo was more decorated, and there is no brick wall seen at the bottom of the screen.
	Donkey Kong Jr.	The vine's leaves are different from those seen in the final game. The tree seen in the top left corner is much less detailed. The Mario and "miss" icon sprites are different.
	Rain Shower	All the sprites seem to be different from those seen in the final version. Bowser's eyebrow is different, Donkey Kong Jr. is not symmetrical, and Princess Peach's face and crown look slightly different. Wario has a much redder nose, and the shape of the face has changed completely. Luigi's hand is smaller, and Mario's sprite was given an overhaul as well.
	Octopus	Very little appears to have changed in the game Octopus. The only visible difference is the change of Mario's sprite, which was given better shading and also faces more to the right.
	Fire	Mario's and Luigi's sprites are fairly shorter.
	Donkey Kong 3	Mario's sprite was taken directly from Super Mario World, whereas Donkey Kong's is slightly different. His tie is a brighter color. The fireball is more swirly (like in Mario Bros.). Donkey Kong's "miss" icon is also very different and is not seen in one-player mode.
	Donkey Kong	Little change was made to the level's background, but almost all the sprites look different from those seen in the final. Peach is taller in this screenshot. Mario's "miss" icon was changed as well. Mario's face is less grainy, while the Para Troopa was changed from a Super Mario World-based sprite into something unique.

Unused data

A few sprites were found in the game's data, which do not appear in the final game.

Sprite	Description
	A sprite design of Mario was to be used in the game Mario's Cement Factory. It looks similar to the sprite used in Super Mario World, but it is not used in the final game.
	Appearing in the game Donkey Kong, an unused sprite for Mario is seen. This seems to be a slightly strange design, as it does not look much like Mario's generic appearance.
	This sprite was to appear in the game Mario Bros., and it seems to be an alternate "miss" icon for Luigi. In the final version, only a Mario "miss" icon is seen (even if the miss was at the fault of Luigi).
	An unused sprite of a heart is seen within the game Boxing. This heart is only a single frame, meaning that it was not made to move during development. In the final version, the hearts are rounder and burst when the player loses health.
	An unused sprite of Boxing's handheld. It was going to be an unlockable game, but it ended up as a starting game.
	An unused Super Star from Fire. It was going to have the same function as the 3-Up Moon.
	An unused sprite of Bowser from Rain Shower. It was going to be his early defeated sprite.
	An unused sprite of Donkey Kong Jr. from Rain Shower. His body was modified in the final version.
	Unused Mario sprites from Rain Shower. His walking sprites were modified in the final version.
	An unused sprite of Toad from Rain Shower. His idle sprite was modified in the final version.
	An unused cannonball from Fire Attack. It was going to have the same function as the Bullet Bills.
	An unused hamburger from Fire Attack. It was going to have the same function as the apple.
	An unused sprite of Luigi from the Gallery Corner. It was going to appear in one of the highlighted places' animations.
	An unused tiny Octopus from Octopus. Its function is unknown.
	Early Donkey Kong sprites from Donkey Kong 3. They were enlarged in the final version.
	Early Wario sprites from Fire Attack. They were enlarged in the final version.
	An unused Waluigi sprite from Boxing. It would have been an attack warning for Luigi.
	Early Peach sprites from Chef. They were more shaded in the final version.
	An early Donkey Kong Jr. sprite from Donkey Kong Jr. He ended up looking forward upon jumping in the final version.
	Early Donkey Kong sprites from Donkey Kong. His tie has a different shading, and he is less saturated, smirking, and not looking down in the final version.
	Early Toad sprites from Mario's Cement Factory. They were shrunk in the final version.
	A text that says "GBG." It would have appeared within the Game Select background graphics.
	An unfinished paint job from the Gallery Corner. When the Gallery Corner stops being highlighted, the paint job progress disappears.
	Early copyrights from the Title Screen. The copyright used in the final version is "(C) 1980–2002 Nintendo."
	Unused Japanese names from the Gallery Corner.
	Unused test-related texts from the Gallery Corner.
	An unused "Transmission error" text in Japanese.
