Hmm...well, what I'm refferring to more specifically are CLOUD.DAT, SEFIROS.DAT, and HICLOUD.DAT. Swapping SEFIROS for the other two in the EXE's source, and CLOUD for SEFIROS, resulted in a very nice change of Seph and Cloud swapping animations for the battles.
The bad thing was Seph's DAT file (?) is/was missing some animations, like the limit breaks, damage, death, etc. I'd like to change it so he has these anims, but how?
