I've got a Konami Sunset Riders pcb that works but is having some major graphics/color issues. The board plays and I can get into test mode and it passes all the tests for the masked roms along with the
I pulled the (2) AM27C020 roms from locations 8G and 8E. The one at 8E was bad so I erased it and reprogrammed it. The rom verifies fine now but it didn't fix the problem.
There are two more roms at 10G and 10E but they are not labeled to say what they are (such as AM27C020) so I'm not sure how I should read those with my GQ-4x4 burner. Can someone tell me what kind of roms they are?

Any help would be appreciated. Thanks!
