I tried to install the Xenophonia mod into my Total War Eras mod to add more voice types. What I ended up with was an 'audio.dat', 'audio.idx', 'events.dat', and 'events.idx' that play all the M2TW sounds in a mod folder without any of the vanilla Music or Voice files being in this mod folder. However all the voice types are wrong, so I had to reorder the 'descr_sm_factions.txt' to get them more or less correct.
Is there any mod that can make the 'audio.dat', 'audio.idx', 'events.dat', and 'events.idx' work in a mod folder without any of the Music or Voice files but won't put the voices in the wrong order? Alternatively is there any way I can edit these files to put the voices in the right order?
Also how do I assign pre-battle speaches to a faction?
EDIT: never mind, I figured out that if you rebuilt the 'audio.dat', 'audio.idx', 'events.dat', and 'events.idx' with all the Music and Voice files present they'd work fine. I also found the prebattles speaches in the export_descr_sounds_prebattle.txt file.
