I made a mini Neo-Geo. The full build took me about 2-3 weeks, check out my notes/pics/videos here: http://forum.arcadecontrols.com/index.php?topic=102735.msg1087637
I recently added a Microsoft Xbox 360 wireless dongle, so a second player can join in with a wireless joystick. I've got a tekken fight stick for this.
