The screen to use was a no-brainer for me. The Sony PS1 Screen of course! See, an arcade machine uses RGB for the video. Not even "component" like a DVD player but real honest-to-goodness RGB. Well the awesome little Sony screen can use that as input! How's that for cool?
The first "test of REAL proof" The system running with everything hooked up. Worked fine, it was time to think about STEREO SOUND...
It's this little 8 pin IC over by the main volume pot. Very similar actually to the spots to get stereo sound from a 1997 model mini-SNES. I also cut the traces after this IC that combined the signal and removed the large audio amplifier (the blank solder spots on upper left) I now had stereo! The Neo Geo MVS Portable would not commit any mortal sins on MY watch!

Now it's time to
cram all this stuff inside a case!
