Playing old school Nintendo games on the Wii can be a pain if you can't get accustomed to their controls using Wiimotes. With Komodo's Retro Adapter, you can plug in any NES, SNES and N64 controllers to your Wii and play instantly.
The adapter, which is shaped like a mini N64 console, fits into a GameCube controller port and has female plugs that receive both first and third party gaming accessories. Available in mid-June for $20, I'll definitely have to pick up one of these so the next time my boyfriend's losing at a game, he can no longer complain that there's "something wrong with the controller."
