This text file contains the necessary to play games in .WUD or .WUX formats. If you use "decrypted" game folders (Loadiine format with code , content , and meta folders) or the .WUA format, you do not need this file. Step 1: Locate the File

If you want to avoid keys.txt entirely, use a homebrew tool like Dumpling on your Wii U to dump your games in a decrypted format.
