The Color GB 100-in-1 is a pirate multicart for the Game Boy line of consoles attributed to "GAME USA Color Advance" as the possible publisher. It was likely released in the year 2001 as this cart contains the English version of The Legend of Zelda: Oracle of Ages which was released in 2001, providing a lower bound of the multicart's release date, and the inclusion of the first two generations of Pokémon games also support that as they were immensely popular and recent games at the time.
Cartridge[]
The black cartridge is the size of an official Game Boy cartridge and its label reads "TOP 100 CLASSIC GAME COLLECTION 128M ALL SAVE NO REPEAT 100 IN 1" and then "UC-100M01" at the top, with "GAME USA Color Advance" being written vertically on the left of the label. It depicts various covers of Game Boy games including Pokémon, The Legend of Zelda, and Super Mario, among others. "Nintendo GAMEBOY TM" is imprinted in the oval on the cartridge. The grooves on the back are slightly deeper than those on an officially licensed cartridge and there's another imprint at the top reading "MADE IN JAPAN" and below "PAT. PEND". The cartridge is held together by a Philips screw instead of the usual tri-wing screws used by Nintendo.
Menu[]

The first page of the menu.
This cartridge uses a menu that allows the player to browse through and select from the games. All titles are organized in pages of 10 in front of a color-shifting, diagonally-moving checker board pattern. Additionally, there's a header reading "COLOR GB 100 IN 1" and "PUSH UP DOWN A KEY" as well as "CGB 100 IN 1" in a fancy font on the bottom of the screen. There is no menu music, however, pressing a button plays a short sound effect. Navigation is done using the D-pad for selecting a game of a given page, and pressing B will advance to the next page. Pressing A starts the selected game.
The names of the games in the menu don't always match the actual ones on the multicart. There's some spelling errors and some games even go by completely different names entirely. Also, due to the limited character space per line, some names are cut off at the end.
List of games[]
The vast majority of games on this multicart are English, licensed games of little popularity, with the exception of some Pokémon games, The Legend of Zelda: Oracle of Ages, Tetris, and Super Mario Land. A few games are in Japanese. This multicart also contains ROM hacks as well as a bunch of homebrew games on the last pages. Not counting alternative versions of games and different localizations, it features 98 unique titles.
