You know those Atari joysticks you can plug directly into your TV, the ones that can play 20-30 built-in games? Well, a member of the Benheck.com forums named Airz has taken that idea to the next level. He's jammed fully working NES, Game Boy, and Game Boy Color emulators into an original Super Mario Bros. game case [via Engadget].
The best part is you can actually buy this thing. It features a 2.8-inch LCD screen, 4GB of storage, a rechargeable battery, and outputs to a TV. If you're interested, just drop Airz a private message on the Benheck.com forums.
