I just picked up a gyruss and it boots but has issues. One amp is out (can see brown discoloration), the cross hatch pattern stays on in upper and lower part of screen, fire button doesn't work, dip switch settings seem to have no effect (stuck on free play).
I removed and reseated all socketed chips and confirmed voltage. There is a small harness hack to bypass/ reinforce one of the grounds that was burned up on edge connector but don't see any other visible damage.
Downloaded and installed shoestring's test rom and get
RAM 3J stack err $97FA
thoughts while I read more threads? Looks like Konami scratched out all the chip model #s or something.
