Game plays fine except DK and Mario and barrels are missing, anyone know what EPROMS or other chips on the PCB are the cause of this?
 
Well, after removing the EPROMS and putting them back in, now I get NO video but I can hear the game lol
 
Some of the things that can go wrong when "re-seating" EPROMs:
-traces under/around sockets damaged by screwdriver during EPROM removal
-EPROMs replaced in wrong sockets (esp if more than one are removed at a time)
-EPROMs re-installed backwards.
-EPROM legs get bent/kinked on re-installtion
