There is a way to do that. A couple of guys wrote it in SUPERTHREAD. But if u mod that, your skills will look different. Idk why but for me fighter skills looked like turtle skills (it maybe sounds fun but it sucks and fail)
Let me look for it. I believe it is prop0 but not sure. And you are looking for those codes. I will say though if you don't know what to do or look for don't attempt modding.
