Hey Guys, need your help here.
I've done several CPS2 Conversions pretty smoothly but this one has me stumped. I'm getting this bad audio:
I first was converting a dead Children of the Atom Board. Rev 6 with an F pal, I ran the wire from pin 7 on the Pal to C13, changed jumpers. Burned all the roms and had that bad sound. Triple checked the jumpers, same issue. I suspected maybe a bad board, so I had a friend lend me his phoenixed Rev 7 Marvel vs Capcom. Since it's phoenixed, I transferred the roms from the MVC to the suspect COTA and it fired right up with perfect sound. Tried the Burned SSF2X roms on the empty MVC board and same sound issues. I was hoping it would work and that I could isolate the issue to the COTA board, but I know the MVC has the right jumpers and pal so it should work just fine. It is behaving the exact same way, with that strange garbled sounds.
In summary I have ruled out:
bad board, wrong jumpers, bad or wrong pal.
I have also burned 2 different sets of SSF2X roms and verified every rom at least twice manually and they all verify. I'm truly stumped here. Anybody else recognize this bad audio or can give me any clues what I'm forgetting here?
