I picked up a Bad Girls recently and was missing the background music. I wasted some troubleshooting time thinking this sound board was unique due to the number MA-886-717. After a brainstorm eventually hit I realized despite the number its identical to to main board in Bone Busters and of course it tested fine in Bone Busters. The System 3 sound board MA1629 also looks to be identical and is still available NOS although I have not tested one out yet to confirm. My missing background music ended up being a bad driver board. I thought I would put this here in case it helps someone else one day.

If anyone out there is crazy and wants a Bad Girls bad enough I have a populated playfield missing A lot of the top side stuff, a lower cabinet wiring harness and transformer. I figure I would at least mention it here since it will all just sit here in storage.
