Unused Graphics

A lot of surprises in here.

Note Board

A font that says "BGM".

Message

Two out of three blocks that comprise the locked Ball game panel are used.

Credits

An unused lowercase font. The Credits names are in all-caps for both the Cast and Staff Rolls.

Toad grabbing or hanging onto something?

Unused Code

Early Title Screen

Present in all Game Boy versions, and can be accessed with Game Genie code 0F1-EEF-B3A or the debug menu (see below). It is unknown when this title screen was scrapped, probably early on as the Game Boy Color features were added as the monochrome US version was released...although it's interesting that Game Boy Color palettes were implemented for this title screen as well.

Game Boy Color	Super Game Boy

Pressing Start takes you to the normal title screen.

Pause Animation

Game Genie code 16C-749-B3E will allow you to select an additional pause animation directly after the final disco ellipse animation. Press B again to reset to the first.

Ball

Ball might have been a last-minute addition, as there's quite a few unused graphics. Game Genie code ??A-04C-E6A (where "??" is one of the below) will access some of these elements, although it'll cause graphical glitches outside of Ball.

Yoshi

What appears to be a Conch shell. ID 09.

What appears to be Birdo's Egg. ID 10.

Koopa

An unused sprite of Bowser where he appears to be wincing, as if he lost.

Planned Peach Stage

There is a full tilemapping for a mostly completed Peach Stage. A Mode Select icon also exists hinting that a Modern Ball stage for Peach was planned. Game Genie codes 911-37B-A20 911-78B-A20 C21-34B-F75 will allow you to access the remnants of the Peach Stage. A few graphical glitches aside, it works as it should.

ID FE

Three of the cookies from Yoshi's Cookie. The "Check" cookie has two parts used for animating the ball-like object. The "Flower" and "Circle" cookies also have both a single stationary and animation set, but neither would display in-game. Game Genie code ??A-04C-E6A (where "??" is one of the following) will replace the "Check" cookie with either "Flower" (09) or "Circle" (10).

Here is the complete tileset for a Peach stage, which is rendered before each stage's tilemapping.

Very Hard Modern Ball

Ball has a fully-coded Very Hard mode for all stages. Game Genie codes 01E-52B-E62 00C-7DB-E62 (01E-2FB-E62 for Game Boy Gallery 2) will allow you to access a fully-coded Very Hard mode for all stages. Because of the way character selection is programmed by pressing Up, you have to select your character and then exit the mode select menu. Turn the code on, then enter the menu. You can select Very Hard mode with the currently selected stage.

Hell, the interrupt save was entirely programmed.

Classic Very Hard Mode

GameShark code 010202C2 or Game Genie code 021-61A-E6A will allow you to access Very Hard mode in all classic games. While the games are mostly completed and the interrupt save graphic was completely programmed, there are a few problems:

• Games will not be labeled GAME C, as this graphic does not exist.
• Parachute, Vermin, and Ball have no noticeable speed increases.
• High scores do not save.

Debug Menu

GameShark code 0101A6C0 0120A7C0 or Game Genie code 201-EEF-B3A (201-DBF-B3A for Game Boy Gallery 2) will start you in a debug menu, although if you use the GameShark code be sure to turn it off when the debug menu is accessed.

Super Game Boy Palette Masking

When Game & Watch Gallery 2 was localized to the US, the SNES controller's A and B-button palettes were not changed to reflect the US blue and purple buttons. Rather than update the palette completely, they forgot to update the attraction attributes, leaving the original code assigned to the palettes visible.

This can be seen by exploiting a Super Game Boy BIOS palette glitch which involves clicking on the camera icon in the custom palette menu, then wait for the palettes to change, and exit the menu with L and R buttons.

Regional Differences

Title Screen

Japan (SGB)	Japan (GBC, Unreleased)	Australia (SGB)	Australia (GBC)	Europe, US (SGB)	Europe, US (GBC)

Game Boy Color support was added outside Japan as well as an early US version released in extremely small quantities, but the Japanese version of the game has never received a Game Boy Color upgrade and was rediscovered as part of the September 2020 lotcheck leak. The Australian release was known as Game Boy Gallery 3, due to Game Boy Gallery being the first title in the series.

While the Japanese version displays the copyright for the game itself, the international versions display the copyright for the Game & Watch games included in the collection.

Museum

Japan	International

Much like in the previous game, the Japanese version shows the initial retail price information of the included games. The International versions, for a change of pace, show instead the name of the system in which the game was included rather than leaving the area blank.

Note Board

Japan	International

The messages feature a quaint border around the top in the Japanese version.
