If it works, that's all that matters. Hot damn, that's a great find. Emulators just ain't the same as having that bit of plastic in your hand. I think I saw news about them making some new 'Classic' box that's got a bunch of games preloaded but eh that's not nostalgia.
You don't know me but if you ever want a player 2 I am 100% down for some Mario Anything. Or Starfox if you've got it. Goldeneye!?
