ok so I found the drawing set, see where I hook up power, speaker and volume control and header J3 has 7 pins controlling selection, my question is where do I get the proper values for these pins for each sound effect to test if there's any logic problems (on 6821 (or 4050/4068/4069))
(my current issue is after replacing a dead ROM board the game plays the wrong sound effects, they are Joust sounds but they occur for the wrong event, if anyone has any other troubleshooting ideas to figure out if it's ROM board or sound board let me know)
