Help with Simpsons Arcade Board

[tecfox]

Hello can anyone tell me if this is a chip problem ? As you can see at Lisa Simpson there is a graphics issue and it goes on through out the game as well. 



Any help on this would be greatly appreciated.

could be a corrupted ROM or a bad scratch RAM chip.

try reseating the chips first. check your voltages next. go from there.
