What is keys.txt?

keys.txt is a plain text file that stores cryptographic keys required to decrypt and run Wii U game files (such as .wux, .wud, or installed game formats). The Wii U uses encryption to protect its game data. When you load a game in Cemu, the emulator needs the correct key to decrypt the executable code and assets in real-time. The keys.txt file provides those keys.

However, anyone who has downloaded CEMU for the first time quickly runs into a specific, cryptic requirement: the need for a file named "cemu emulator keys.txt" (often referred to simply as keys.txt). Without this file, your legally dumped game files (WUD, WUX, or RPX) will remain locked, appearing as nothing more than encrypted data.
