Does anyone knows how mod armor skins?

[Kai]

I have seen some mods for swapping armor but just for clothes using PPSSPP with a texture folder. I was wondering if I could swap armors or just replace with some modded skin.

I have tried to extract the DATA.BIN (from FUComplete) with mhtools but I think I don't know how it works even I have studied programming for the last 3 years lol

edit: I just managed to swap textures but I realized I wanted to swap models.



thanks!
