Finished this a few months ago, I know it's been done before, but still having a blast with this system. I used Marq's CPS 2 Digital AV board for video and sound output, and @undamned USB to Jamma converters for the controls. Powered by a pico PSU.
Thanks! Standby for internal pics, currently updating the cps2 digital AV board. Marqs just released a new firmware that finally incorporates an on screen display and scan lines!
Its more of a prototype for me. I'd like build another, but use ribbon cable instead since my wiring looks like trash. Photo with my Brazilian frankenstein SFA3 just to show updated video output with the new firmware for the digital av.
