The game that had the medium resolution was NBA Showtime. The game that had the low resolution was Namco Final Lap 3. I don't know the make of the Namco, all I could find on it was Philips, so I know its a Philips. The NBA Showtime had a WG 7501 in it which still works.
I took the low res out of the Final Lap 3 and was putting it into the NBA Showtime so I could use my NBA Hangtime PCB in the Showtime Cabinet. Hangtime is a low res game where as Showtime can be both a low resolution AND medium resolution.
I just took the low resolution philips out and I can't see anything wrong with it but when I put it back into my Final Lap 3 it now does nothing.
Advice?
