this surprises me greatly, there are obvious 'bad dump' type problems with the explosions etc.
if the PCB caius has exhibits the same problem it's possible it's been repaired with bad roms at some point, this is always a possibility.
if it doesn't, then it could be some encryption, but last time I looked I concluded it was more likely they were bad roms.
