I guess this is worth mentioning but I'm doing this step for myself since I plan on doing major tinkering with the battle script sets.. the issue is finding the space and looking over the battle scripts, there is a ton of duplication being done and I'm really thinking about reclaiming some of it via documentation, so I can do more.
So.. I'll be updating this post as I'm trying to dissect some of these issues...
Non-Lunar Subterrane/Bahamut Cave scripts:
0x00 = 0x38, 0x7E, 0x7F, 0xE0
0x08 = 0xD2
0x17 = 0x2D
0x6D = 0xA4, 0xF2
Lunar Subterrane/Bahamut Cave scripts:
0x3E = 0x41
0x03 = 0x09, 0x12, 0x1D, 0x53
0x0A = 0x15, 0x2E
0x10 = 0x34
0x29 = 0x4F
