I ended up extracting the *.arc files from Xi Coliseum perfectly, but now I need help with extracting the models. I saw some key names like texture files and bones but that's about all I saw while looking at the hex. I don't have much experience in these kinds of things so I was wondering if anyone with a bit more knowledge on these file types could help me.
In the end, the model should look something like this. (Might've grabbed the wrong model, not too sure.)
what is going on in that little head of yours rossi?
EDIT: I have no idea where the files went when I attached them so I'll just point to my Google Drive.
