It's for the Nintendo GameBoy. I'd love to have this game!!! One of my childhood favorites! However your description is less than positive about the condition of it. There's only a day left in your auction....if I may make a suggestion? Take the game to your local GameStop, FYE, GrayShale or anywhere they sell used games or consoles and have them test the game(it will be free)!!!! After that you can update your auction to be more legitimate sounding! Good Luck!
