Hello pinsiders I have a couple of quick questions the game I’m working on is space invaders the issue I’m having is the wrong sounds playing for different targets but the right sounds for this game and the background sound comes and goes but only at a high speed I was looking up the info for the sound board and it is coming up as a silver ball mania board number as-3022-3 and the u4 chip also is a e-786-11 also I believe for silverball mania. Could this be the problem wrong board and chip? The game plays great other than the sound issue. Thanks for looking and any help I appreciate it and sorry in advance if this is a stupid question I’m fairly new at bringing pins back to life.
