I have a 4 player TMNT PCB that I currently installed into a Sunset Riders cabinet. TMNT plays fine, but the sound is distorted. While playing the game the music will play fine, but when sound effects come into play the sound along with the music gets distorted. If you defeat all of the enemies on screen, then the music kicks back in. Anyway, any ideas on what could be causing this issue? Thanks in advance for all of your help.
