How do I rip textures from super mario galaxy

[Resistiv]

That's because you actually have to edit the model file itself to change the path of the texture. I recommend converting the model to a Collada DAE file, and then using this thread to help you figure out how to edit the file: https://www.vg-resource.com/thread-25927.html (go to the "Next you have to modify your .DAE" section). Also, a useful tool for converting models of different types is Noesis, also found in the thread linked above.

Hope this helps, cheers!
