[Game Request] Mario & Sonic at the Olympic Games (Wii)

[Marusero110]

What game would you like to see supported?
I would like to see the Wii version of Mario & Sonic at the Olympic Games supported.

What assets from this game are you most interested in?
I am most interested in the 3D models for the Mario and Sonic characters.

Do you know of any existing tools/documentation for this game?
The only tool I know of for Mario & Sonic at the Olympic Games is this one, which aims to extract content from CFC.DIG and CDDATA.DIG files in various games developed by Racjin.

What would you hope to do with this game's assets?
I hope to use the game's assets for preservation, development for fan games and prototypes, and 3D model sheet creation (specifically for character models).

Additional context
So far, I managed to extract the 3D models for the characters via Ninja Ripper, and they were already in a T-pose (even though they were also split into various parts, forcing me to merge them appropriately in Blender). However, I could not get my hands on the skeletons for the models. I also tried using Raw-man's decompression tool for Racjin games, but while I successfully extracted the content from the CDDATA.DIG file for Mario & Sonic at the Olympic Games in the form of binary (BIN) files, I don't feel very confident using a hex editor to obtain my desired assets. As a bonus, you can look at the game's TCRF page for any content not present in the final game.
