Getting smash tv ready for CAX. Board in the cab has a small problem. Pcb passes startup test all chips green.

Game looks like it works and the pcb will generate a proper picture until you start moving around. At that point, it starts to leave like a ghost image of whatever player 1 crosses over.

I will post a pic in a bit. I am going to try swapping chips. Its not critcal to fix it for the show as I have spare working board..

My spare board has L8 eproms. Pretty sure thats correct for pleasure dome.

nevermind..

I got lucky and and the 2nd group of chips I swapped fixed it. it was one of these:
u52
u53
u65

All thats left is some final cabinet cleanup and its ready for CAX.
