Released in 1998 brought the power of the GameShark to the Game Boy and Game Boy Color. Preloaded with codes for 158 games, but unfortunately, new codes could not be saved. It did however contain a feature called Game Trainer, which was a way to create new codes. Memory Erase was an additional feature which allowed users to clear all saves from a Game Boy cart. The GameShark for the Game Boy can also be used with the Game Boy Advance, as long as the cart connected is either for Game Boy, or for Game Boy Color.
