Exerion pcb repair
This game had the wrong colour background and vertical lines through the background and sprites. After checking a few fujitsu ttls with the logic comparator it flagged a 74LS157 @ F11.
This was confirmed with the logic probe and chip replaced with a socketed and a new LS157.
Repair complete.
