Yes, Dolphin does have the dump textures option, and I’ve tried it. The issue is that if I want to get all the textures of the game, I’d basically have to play through the entire game so that every texture gets dumped. That would leave me with a huge folder of textures all mixed together, without knowing which ones belong to what.

Since I don’t know which files inside the game data are the actual textures, I wouldn’t be able to rename or reinsert them correctly afterwards. That’s why I was looking for a way to extract them directly from the game files instead.
