:/ Unfortunally i did it manually, i have thought about asking your automatic modifier, but i finally renonced because 80% of the DAT contain cloud's original animations, so i didnt just modified the number of bones and parts, but changed cloud's animation too ( if i modified only the number of bones and part sephiroth would display cloud's field animation and many glitches)
Thats why it took me so much time now i can finally breath lol
EDIT: thats why the "glitch" on makou reactor was really annoying, if makou reactor could work for PSX, i could just modify every animation with the program, save it ( so no need to re insert everything) and then use your automatic program because the only thing left to modify in the dat would be the number of bones and parts
I forgot to mention for my manual method, about comparing an original DAT with a modified one with makou reactor, i didnt changed EVERY difference, otherwise the game would crashes too, i just modified the animations script section differences, all the rest is "bad "differences
