I thought I'd write this down for people that haven't read some of the other threads that have this information. Enemy battle scripts are loaded from two different places in the ROM depending on the current location map. I did some quick tests, and it appears that the only maps that use the "Lunar" enemy scripts are the Lunar Subterrane maps and the Cave Bahamut maps. All others, including the moon surface and lunar paths, load from the normal enemy scripts.
