The CM-42 Games Color 37 in 1 (or Color GB 37 in 1, as the game's menu calls it) is a pirate multicart for the Game Boy Color.
No game is repeated on this multicart (except different versions of Pokemon). It includes 9 Game Boy Color games (including GBC backward compatible games) and the rest are Game Boy games. There are no pirate originals on this cart.
List of Games
Tom and Jerry
Contra Alien War
Mario and Yoshi
Hyperloderunner (Hyper Lode Runner)
This cart contains 3 spots of epoxy resin on the pcb and a cage for the cr2032 save battery so you don't have to solder the battery on the board when it needs replacement. The cart is held together with a simple phillips head screw for easy opening without the use of a game bit. There is a red and blue variant of this cart. The shell is a little thicker than a retail cart and has no indent on the front where the text "Nintendo Game Boy" would be, making it harder to pull the game out of the system. Perhaps the most interesting thing about this cart is that the games are in NTSC USA, meaning the Pokemon games are in English. The dumped roms header is Pac-man SCE (with a different checksum) and is the only game that can be played since it is the only one with data on it (the other games will softlock an emulator).
