You’ve that a massive NES controller to play with, but what about one you can fit in your wallet? This awesome-looking all-copper capacitive NES joypad that’s about the size of a credit card, and can be made at home with the help of a KickStater project, might fit the bill.
How much do you want to prance across this NES controller, which just so happens to be the world's largest gamepad? If you hotfoot it over to Liverpool Street station in London today, you can button-mash with all fours, while playing Tetris against a world-champ. No, not Dr. Mario, I'm afraid to say.
You know the trick. When the game wouldn't load properly, you would take it out, blow in the open end to dislodge dust, grit, peanut butter, or what-have-you from the electrical contacts, then put it back in and hope that it worked (or repeated as necessary).
