Description
User Pat86 on Reddit reports a fatal error during the Two Face boss fight in the PAL version of Adventures of Batman and Robin. The proximate cause of the fatal error is improper decoding of an illegal instruction, which is being tracked separately in ticket:8. However, it seems unlikely that the game is depending on an illegal instruction trap for proper operation so more investigation is needed to find the root cause.
Note:

for help on using tickets.
Turns out the illegal movem observed here is never actually executed. The fatal error here is triggered at translation time, not at instruction execution time. As a result fixing, ticket:8 also fixed this.
