I would like to rip some character models from this game. I extracted the contents of the CPK that I think contains the characters with CriPakTools (The Noesis CPK extractor didn't work), but the extracted files don't have names nor extension and almost every file has an "FPAC" header.

I could find some other words in the file like "FPACMAT", "FPACTRANF", "FPACMESH", "FPACTEX", and some others.

Sample files:

llsip_files.rar

I think the larger files contains model and texture/image data, while the smaller ones only contains texture/image data.

Any help would be appreciated.

I decided to examine one of the files (108) with Hex2obj, and I found these:

108_mesh1.png

108_mesh2.png

I believe this format isn't anything complicated, but I could be wrong.
