Cemu Wii U Title Keys — Quick Guide

What they are

  • Title keys are 128-bit keys used to decrypt Wii U game content (RPX/RPL files, game archives).
  • They’re required by emulators like Cemu to load encrypted game files.

Why they matter

  • Without the correct title key, an encrypted game dump won’t run in Cemu.
  • Matching key versions (title key + game revision) ensures files decrypt properly.

How to use them in Cemu

  1. Place title keys in a file named keys.txt.
  2. Put keys.txt in Cemu’s main folder (where the Cemu executable is).
  3. Format: each line contains <titleID> <titleKey> (space-separated). Example:
    • 00050000101C8F00 0123456789ABCDEF0123456789ABCDEF
  4. Restart Cemu after adding or editing keys.
  5. If a game still won’t load, confirm title ID and key match the game dump’s version.

Finding the correct title ID

  • Title ID is an 8- or 16-character hex string. Common format for Wii U single-game titles: 00050000XXXXXXXX.
  • You can often find it from the folder name of a dumped game, or from the game's metadata (e.g., in the game’s Ticket or metadata files).

Common issues & fixes

  • Wrong formatting in keys.txt — ensure uppercase hex, no extra characters, single space between ID and key.
  • Key corresponds to a different region or update — try locating the key for your specific title version.
  • Corrupted dump — verify file integrity (redump if necessary).

Security & legality

  • Title keys are part of copyrighted games. Only use keys for games you legally own.
  • Do not share or distribute copyrighted game files or keys publicly unless you have legal right to do so.

Quick reference

  • File: keys.txt
  • Location: Cemu folder
  • Line format:
  • Restart Cemu after changes
