I will post a real review with pics at a later date, but here are the first impressions:
It is HUEG.
Buttons are AWESOME, better than stock SNES pad. Dpad is terrible, but at least has a pivot point. Battery lasts about 2 hours.
By ripping it apart, you will find a composite input 3.5" LCD with a TINY driver board, about the size of a credit card cut in half. You will also get two circiut boards: One is a TINY SNES board, almost exactly the same size as a DS Lite motherboard, but no as tall. The other is a massive board that plugs into the SNES board via 16 wires. The big board contains the audio amp, controller board, interface for the wireless controllers, LED driver for the screen backlight, and the assorted switches, ports, and dials. My first step is obviously to run the tiny board without the big support board. If I can do that, this thing will be crazy small.
