So I suppose this really isn't a clone so it belong here in the Misc catagory. It's a device that allows you to view/play Gameboy games on an N64. It can also be used by the tech savy out there to develop thier own gameboy games. This particular unit looks cobbled together by hand, there are also manufactured units one can find on various Hong Kong websites. (Chick here for a page on the Wideboy 64 ABG.) Stuff like this pops up on Ebay now and then but usually gets pulled becasue of it's development capabilities (stupid Ebay.) While I know nothing about GB programming it would be cool to own something like this to rip roms, back roms up, etc.
