I'm looking at a Willow boardset for a local collector. The game plays fine and seems to sound fine, but has some pretty severe graphic and letter issues. Many graphics (static and moving, not sure if every component is considered a sprite) are missing layers or colors. Letters are all rendered correctly, but have the wrong colors. The game passes self tests and does show that all colors are present within the service menu. I'll attach a couple pics of the issues I'm seeing.
My troubleshooting process has been as follows:
-Reseated A, B, and C boards. No bent pins, connections feel solid.
-Verified voltages between the PSU and B board. Tested in two different jamma cabs - no difference.
-Tested with a known working A board - no change.
-Tested a known working B and C board on the Willow A board - no issues.
At this point, It's definitely something on the B or C board.
-Reseated and cleaned the pins on every socketed chip on the B board. No change.
Ideas? Perhaps a corrupt ROM?
