This happens occasionally. If it happens in-game, it continues until I trigger the turbocharger, or drain the ball, then it goes away. If it happens when the game is in attract mode, it just continues with what seems like an ever-increasing pitch, until I get scared the game will explode and restart it.

Man, you don't know what you're missing. Well, I guess you do, since you watched the video.

I'm thinking this, between the weird sound and the squelch when I turn off the game. Also, when I tried an L5 rom once, the sound turned completely stupid. I did order a new set of ribbon cables today. Maybe I should consider a new sound board too.

Finally got back to this one today. Ribbons are replaced, ROMS are good. I received an order of caps from GPE, my plan was to recap the board thinking this was the last possible source of issues. When I pulled the board and had a much closer look, I found it had already been recapped, and rechipped, and there's a lot of really bad soldering going on. Swapped the board with the one from DW and the sound issues go away. So somewhere.... the board must have something shorting, or something open, or god knows what. I'll recap in case they reinstalled a bad one, and that will help clean up some of the bad solder too.

Thanks!

Recap and no change. Tried going the other way and testing this board in DW, and DW didn't even want to boot or display properly. Looks like I'm -1 audio board, guess I'll have to get a pinsound board to pimp my DW and use that board in Getaway.
