Hacking Decompressing GCN Files

[Eltoshen]

I've been meaning to decompress some of the graphic files on a Gamecube disk to get a closer look at a character design, but at the moment, I'm unaware of how I'd be able to do so.

I've already extracted the files. They're something like "FILE_50004202".

How would I go about extracting the graphics from such files?

btw, these graphics are 2D, for the most part.
