I went in that store on monday and I bought 2 games and a Game Genie.
And so I tried hours on end to get the Game Genie to work. I tried cleaning and still nothing worked. And so I took it back and now I got this controller called "Zipper". And I plugged it in and nothing happens I tried pressing all the buttons and still nothing.
I will take the zipper back to the store and pick up the normal Nes controller... I hope it works!.
