Japanese MVS/MASS Supergun HELP!!!

OK, every game I start up goes into a diagnostic that I can't break out of. It's driving me NUTS! Once, I got a game to come up, but no sound. Look, I got this basically with no instructions, and the person I got it from has no idea either. Her husband died and she could care less about the stuff. I just want to figure out how to play all the carts...Any help? Also, the supergun controllers won't register the "D" button on the diagnostic test. WHAT THE HELL! Thanks in advance.

The D button is not regular JAMMA (that only has 3 buttons), so you have to wire it yourself. Obviously that supergun wasn't made to play MVS games so it isn't wired. You just need some wire and soldering.

About the propblesm, my guess is that your board is somehow damaged, but I could be wrong.

Good luck.

yee-Haw! Got it working, miracle! Ninja Masters, here I come!
