Hey there. I'm looking to rip textures from Super Mario 3D World (more specifically, any textures to do with the sky), but ran into a bit of a road block. I was able to get the .szs files through Crediar, but rarcdump doesn't seem to work after using yaz0dec. EveryFileExplorer doesn't seem to be doing the trick, and SZS Explorer gives me a "cannot load" error with every file. If anyone can point me in the right direction, it'd be much appreciated.
