The keys.txt file is a simple plain-text document that Cemu reads upon launching a game. It contains the necessary cryptographic keys in a specific, machine-readable format. When you open a game file, Cemu cross-references the game's unique ID with the entries in your keys.txt to find the correct title key. If found, it decrypts the game on-the-fly into your system RAM, allowing it to be executed.
The keys.txt system is a for purists and those with physical game backups. However, for most modern users, it is often viewed as an outdated inconvenience. If you want a "plug and play" experience, it is highly recommended to use decrypted game folders or the .WUA format , which removes this technical barrier entirely.
| Problem | Likely Fix | |---------|-------------| | Game doesn’t boot | Ensure correct title key is present. Check the game’s Title ID (shown in Cemu’s game list). | | Cemu says “Missing key” | Add missing key or update Cemu to use online key retrieval. | | Multiple keys with same Title ID | Cemu uses the first valid one; delete duplicate entries. | | Keys.txt not being read | Place it in Cemu’s root folder or import via GUI (Options → General Settings → Add Game Keys). |
