The game had a CVS style archive on the disk in .PAK, and there's tonnes of these .rom files in various folders.
These examples come from the /BATLE/ folder. (Great spelling, Konami)
I've checked them out in a hex editor, and it starts with ".mor" - I assume the format that it actually is?
If anyone could help me out, that'd be great, and I'm sure that tonnes of fans would be very grateful!
