Figured I could make a topic 'bout this one.
I made a program that can alter the c0mXXX.dat files from battle.fs from FFVIII if anyone are interested. I named it ifrit!

This proggy can not directly edit the battle.fs. At least not yet. You need to extract the files yourself. Ifrit can open files including c0m000.dat - c0m143.dat.
v0.10 Download here!Requires Microsoft .NET Framework 2.0.
Minimum screen resolution should be 800x600. Should at least be 960x600 though.
Please let me know 'bout any bugs (features

). I know re-naming enemies may not cause desired effect.

Extract and pack/create archive features.
The help file is NOT updated.

Ifrit can open c0m127.dat, extract files, etc.
When creating an archive (battle.fs) from a folder, not all battle files (from battle.fs) must be contained within that folder. If that is the case, the destination folder, in which the archive is created, must contain the files with the battle.fs, the battle.fi and the battle.fl from the ff8 data folder. They don't need to be the original files, but must be valid/playable files. I suggest keeping a backup of the original files and your altered files (battle.fs, etc).
