Neat, kinda. But i don't see why someone would pay $130 for this. It's kinda in the same ballpark as developing a token ring interface for an Atari 2600. If you want to play gameboy games on the big screen, either emulate, or get a Super Gameboy adapter (for like $10 on eBay) and slap it in a Super Nintendo (like $30 or less). Will do the same thing, and costs a hell of a lot less. I do give him credit for developing it, but it's not really a $130 item.
