Hello, I recently purchased a wrestlefest pcb and when I powered it up, there was no sound. I am using a supergun in which I know to be working as I have tested it with other games right beforehand. Does anyone know if this board requires -5V? Also, the colors are all funky as well, as I can not get the correct colors on the screen... looks like a color might be missing? I am able to tweak RGB values on my gun, but no combination seems to give me a natural skin tone for the wrestlers.

If anyone has any ideas on either issue, it would be most welcome!!
 
It doesn't need -5v. Is this a working board?

For the skin color it sounds like a dirty sync problem. If you haven't installed a sync cleaner, you should.

The sync cleaner is there.. but I will double check that it's jumpered correctly. I got the sound working, i just had to tweak the potentiometer on the board to adjust volume.
