My earthshaker has an issue where the sounds get messed up and distorted. I replaced the cable for the sound board. Replaced the roms on the sound board and all the caps on the sound board. It seems as though I have a system 11A MPU in this game as the sound section is fully populated on th MPU replaced all the caps in the upper left hand side of the MPU and it still has the same issue. I have not replaced the sound roms on the MPU. That was going to be my next step unless someone has another idea. If I leave the game on for a while it seems to clear up. Link to just a little bit of what is happening right at the end of the video you can really hear the issue.
Thanks,

pinmike Yeah I should of included that as another thing I already tried.

Just tried both of those no go still has the bad sound.

Yeah im going to just order all the roms and replace them on the MPU. I will update if there are any changes.

Yeah its stange because the sound can get all messed up on a ball like really bad then when the ball drains it will like reset and be perfectly fine.
