GameCube Model Ripping Software for Linux?

[August Renders]

Hello. I am trying to help a friend of mine who is having trouble extracting models from GameCube ROMs on his Linux computer.
He has tried using a Windows emulator, but has unfortunately been met with errors. If you know any model ripping tools that are
compatible with Linux, any help would be appreciated.

I should add that my friend is trying to extract .str files.

Sorry, but this one didn't work. My friend was hit with a message saying: "Unrecognized or unsupported file type! (or no valid object found!)"
