Thats why i said " use only projectile limits break "
Like beast flare, liveware, nightmare etc,
You must know when red13 use sled fang, his animation is unique, just like the fire effect around him when he run very fast, it mean if you use the runing animation of galian beast the fire effect WONT follow the galian beast but the red 13' original speed animation, to summarize , its uncompatible.
Why use berserk dance in the first place as a limits break? berserk dance is his " attack" animation, if you want to give him this as a limits break its no sense, its will just be the same as his physical attack, so just try with beast flare for begin with. I used this for my mod and its works perfectly, i would say thats the easiest part of a mod, changing the limits break, because everything is automatic with the libre.exe
Just copy every values, ( exept the camera ) into sled fang and patch it. I never tested it for PC but this program works fine on PSX. The crash occurs when you use the limits break or at the begining of the battle?
