To play the decrypted image, extracting only the GM type partitions should be enough. Wudecrypt has a fifth optional argument which can be SI, UP, GI or GM depending on which partition types you want to extract. If you have all of these files, you can run wudecrypt via the following command: wudecrypt path/to/image.wud /path/to/output /path/to/commonkey.bin /path/to/disckey.bin The Readme has the following instructions to run the decryption process:įor wudecrypt to work, you will need a WUD image, the corresponding disc key and the Wii U common key. The source code can be found on the same github repo. You can download WUDecrypt 0.1.1 on the github page here.

This is a “work in progress” release and the developer mentions the tool will be slow and might crash. It’s also open source if you feel like contributing. Makikatze’s tool is compatible with Linux and MacOS (and Windows as well).

Tools already exist to decrypt those Wii U images provided you have the right set of keys, but they are Windows only. WUDecrypt is an open source tool to decrypt Wii U disc images in the WUD format.
