The pandora's box can go now because the Game King has arrived. I've seen these used in the arcades here in Japan. They are pretty powerful solutions for arcade cabinets. Runs 3D stuff such as Capcom's early 3D fighters, Soul Edge and a few others as well as all the classics. Unlike Pandora's Box 3, all the games work really well. Games that had big issues on the pandora's box such as the Konami games all work perfectly here. Basically the unit is a PC with a JAMMA interface attached. Works really well and offers various video outputs. VGA 31KHz, NTSC / PAL / Sega 21KHz format. There's also stereo sound out put too! I have mine running via VGA to a VGA to HDMI converter (Direct signal) then that goes in to the Framemeister's HDMI in so I can add scan lines and change the image to an arcade look rather than VGA look. The end result is very impressive. You can see one of two sets of dip switches in this picture The smaller box on top is my supergun Xexex running perfectly!
