Attempting to use a Gameshark with the N64 Transfer pack would result in Pokemon Stadium claiming the inserted cartridge was corrupted. However, if the player saved the Pokemon Game while Gameshark cheats were enabled, they would be saved to the game cartridge permanently. Thus allowing the modifications to pass Pokemon Stadium's Game Boy Cartridge check. This could lead to some unusual in game battle animations if Pokemon were given moves they couldn't normally perform. A booklet was included with Gameshark version 3.1 with over 2,000 codes to modify Pokemon games and their monsters.
