Ok guys, this is driving me crazy.
I had a dead MvC board and decided to convert the thing to a progear. Video is fine but all i get is some sound effects and about half of the music which is tinny and scratchy (including the Q sound jingle)
I've checked all jumpers with a multimeter and they check out fine.
Here's where it gets weird. This board had seals on it from capcom, a PALG chip in PAL3 but underneath it had a wire patched from pin 9 of the PAL to pin 13 of CN5
The board is a REV 4
Now I thought this was done by capcom to trick a board into thinking a PALF was a PALG so no idea why they would have had to do this.
I've tried the following:
Leave the patch wire in place, lift leg 7 and wired that to CN1 pin 13 (assuming the PALG chip was reflashed a PALF from capcom)
Leave the patch wire in place , lift leg 9 and wired that to CN1 pin 13
I've also done the same two things with the patch wire from underneath the board removed.
Any help would be appreciated.
Thanks
