I was hoping someone could help me. I put a Rottendog MPU327 driver/mpu board in my flash and all was working as it should. Then I push the 2 black button on the board to try and figure out how to put it on 5 ball. Didn't figure that out but now I lost background sounds when I play the game. All other sounds work. I cant find information on how to adjust the setting other than the dip switch settings. Anyone know how to get my sounds back? Thank you
