Tested working on the bench for audio, video, coin, start, and joystick 4 way directions (I don't have a fully populated test harness or rotary sticks to test with).
Issue: one background graphics layer is the wrong colors upon cold start (that's the gold/yellow in the pics) After warning up, that layer looks 95% correct but does have random color dots/twinkles.
I will post a video link of the issue.
