I've been doing lots of reading and learning here but this is my first post.
Picked up my first pinball machine a couple months ago and have been slowly getting it back to 100%; it's a Lady Luck from 1986 using the Bally 6803 MPU and a Cheap Squeak sound board.
My current stumper is that the background music that always plays, and the tune that plays when the 10x bonus is triggered have never played. Basically all music is not present, but all sound effects are present and work as they are supposed to.
PIA? Need new sound roms?
Thanks so much for your help!
