The Nintendo Wide Boy, a piece of development hardware for the GameBoy, is both an interesting collector's curio and an incredibly handy bit of hardware that allows GameBoy games to be played on a TV screen. Though it wont be cheap, you can actually grab one in great condition via this Nintendo Wide Boy auction. The Wide Boy comes complete with a particularly interesting Famicom emulator console (the Famulator apparently) and a boxed copy of Ghostbusters 2 (Japanese version). Seller ships worldwide. Oh, and you can find out more about the Wide Boy here.
