This Game Genie is for Nintendo NES, that allows you to put in special codes to allow you to jump your way through levels in games and cheat your way through games as well with special abilities and such.

Tip: NES Game Genies can also be used to help stabilize a game that is getting old and may be extremely fussy. You do this by using it the same way you would normally play game cartridge in the game genie but without the codes. It will keep the cartridge from moving around inside the game system.
