[Question] Where did you find a feature-complete write-up on the BCRES (BCMDL/CGFX) format?

[Lollio64]

I've been looking for a feature-complete write-up of the BCRES format everywhere on the internet, as I wanted to implement the format in my Game Engine. Even though I already found the documentation on 3dbrew and a linked archive of another wiki trying to explain the format, I found both to be insufficient (a bit uncomprehensive) for all my intends and purposes. Does any developer of this project have a more detailed write-up on the format?
