Problem: Character graphics mostly messed up, main character was fine until he extended it bionic arm thing and went up, bad guy graphics were stuffed.
Fix: Using the scope I was able to trace the corrupted graphics back to the roms containing the character sprite data. Taking each rom out and reading it showed that roms 9, 19, 20 and 22's data was corrupt. Reprogramming some new roms fixed the problems 100%.
