A complete NES in a cartridge. This NES cartridge casemod holds a complete library of NES games, uses the original buttons, resides inside the Super Mario/Duck Hunt combo cartridge. Awesomeness? I think so.

But that isn’t all it does. It’s also an mp3 player, movie player and an FM radio receiver. It also features video out so that you can play on the big screen if you want. If only the NES had been this small originally.

The best part is there’s no need to put cartridges into it. It’s already a cartridge.
