The file starts with a list of all the bones in the skeleton. The first value is a 32-bit count, then the following structure loops.

The CINF format is for skeletons. Skeletons are associated with models and skins through ANCS files.


This file format is almost completely documented
What is the purpose of the bone ID section?


To do:
MP2/3/DKCR differences
