Looks cool, but I kinda just a little bit wish it looked more like this:
That's a plug and play Cannon Fodder, Sensi Soccer and Mega-Lo-Mania game. But... the case is a great size to fit a Raspberry PI, the controllers are pretty much as good as original MD ones, and they are parallel wired - so they could be adapted to work on anything. I have one, and I am installing a Pi with all the games, plus all the SNES games through USB SNES controllers of course, can't leave out the SNES.
If it wasn't for me having that plug n play PI project, I'd be all over that!... although, before I typed this, I had to check and make sure that Kid Chameleon was on the list
