Cemu is a Wii U Emulator.

Website: https://cemu.info/

GitHub: https://github.com/cemu-project/Cemu

Compatibility List: https://compat.cemu.info/

This page is for the native build of Cemu. EmuDeck includes the native build of Cemu as an optional install. Both versions will remain installed. One quick way to tell the difference is to compare the two GUIs. For the Proton version of Cemu, visit Cemu Proton.

Back to the Top

IMPORTANT: Cemu is shifting away from encrypted ROMs (WUX, WUD). It is strongly recommended you use decrypted ROMs (Loadiine, WUA). Decrypted ROMs do not need any additional configuration and should launch without any issue.

Cemu is a fairly straight-forward emulator to set up, if you use decrypted ROMs. Place your ROMs in Emulation/roms/wiiu/roms. Do not install your games. No additional setup is required.

Read the Configuration section to learn more about Cemu and its folder locations.

For updates and DLC, read How to Manage DLC and Updates.

To launch your ROMs in game mode, use Steam ROM Manager and use one of the following parsers to play your Wii U ROMs:

  • EmulationStation-DE
  • Nintendo WiiU - Cemu (.rpx) - Native or Nintendo WiiU - Cemu (.wud, .wux, .wua) - Native
    • Read the File Formats section to learn more about these various file formats
    • .rpx and .wua are decrypted ROM formats
  • Emulators

If you intend on using encrypted ROMs, proceed to the Setting up Cemu Questionnaire.

IMPORTANT: Cemu is shifting away from encrypted ROMs (WUX, WUD). It is strongly recommended you use decrypted ROMs (Loadiine, WUA). Decrypted ROMs do not need any additional configuration and should launch without any issue. If you use decrypted ROMs, you do not need the following questionnaire.

Setting up Cemu Questionnaire

  1. Is your ROM encrypted? If yes, do you have a keys.txt in the right place with the correct keys for your games in the keys.txt file?
    1. What are keys?: Keys are required to decrypt Wii U ROMs. Your keys.txt needs to contain keys (one key per game) that must be dumped from a Wii U console. Any other method of obtaining keys is piracy and cannot be discussed here or on the EmuDeck discord.
    2. Which Cemu ROM Formats are encrypted?: File Formats
    3. keys.txt Location: /home/deck/.local/share/Cemu/
    4. If your ROM is NUS Format (a folder with .h3 and .app files), you will need to decrypt your ROM into the Loadiine format (folder format with three subfolders - code, content, meta). Decryption methods cannot be discussed here or on the EmuDeck discord.
      • The NUS format cannot be used through ES-DE, Steam ROM Manager, or Pegasus.
  2. Is your ROM decrypted?
    1. Which Cemu ROM Formats are decrypted?: File Formats
    2. If your ROM is decrypted, place the ROM in Emulation/roms/wiiu/roms. Your game should launch without needing any keys.
  3. If you are getting an Unable to launch game error, did you place the keys.txt in the right place?
    1. keys.txt Location: /home/deck/.local/share/Cemu/
  4. If you placed the keys.txt in the right place, and your ROM is still not working, does your keys.txt have the correct key for the ROM?
    1. Even if you placed a key for your game in keys.txt, you may still have the incorrect key.
  5. Did you transfer your ROM from another computer and did you compare file sizes to ensure it transferred successfully?
  6. Did you turn on Proton in Steam? If yes, turn it off. If you are unsure, check.

Cemu Native Folder Locations

Back to the Top

These file locations apply regardless of where you chose to install EmuDeck (to your internal SSD, to your SD Card, or elsewhere). Some emulator configuration files will be located on the internal SSD as listed below.

$HOME refers to your home folder. If you are on a Steam Deck, this folder will be named /home/deck (you will likely not see deck in the file path when navigating using the file manager).

Paths beginning with Emulation/.. correspond to your EmuDeck install location. If you installed on an SD Card, your path may be /run/media/mmcblk0p1/Emulation/roms/... If you installed on your internal SSD, your path may be /home/deck/Emulation/roms/..

Note: Folders with a . (.var, .local, .config, etc.) at the beginning are hidden by default. In Dolphin (file manager), click the hamburger menu in the top right, click Show Hidden Files to see these folders.

The Dangers of Proton

Back to the Top

IMPORTANT:

There is outdated info on the internet that indicates you need to set Proton on Cemu or on games added for this console by Steam ROM Manager in Steam. Turning on Proton is not necessary. DO NOT set Proton Compatibity on Cemu or Cemu games added to Steam. Do NOT set STEAM_COMPAT_MOUNTS in parameters.

Turning on Proton is not necessary because this is the native linux version of Cemu.

Do not open the Compatibility screen in Game Mode. Do not touch any of the settings on the Compatibility screen in Game Mode.

How to Roll Back Cemu to an Older Version

Back to the Top

Preface

Your ROMs launch using a script created by EmuDeck, cemu.sh in Emulation/tools/launchers.

The script launches the corresponding emulator in /home/deck/Applications and specifically looks for two traits:

  • The most recently downloaded version of the emulator in /home/deck/Applications, based on the file/release date.
  • The emulator name at the beginning of the file. Anything after the emulator name is ignored.
    • For example, if the latest version of the emulator is 1351 and you would like to downgrade to 1349. When you download version 1349, you could rename it to EMULATORNAME-1349.AppImage, and EmuDeck's script will ignore the -1349 in the file name, allowing you to record which versions of the emulator you are using through the file name.

How to Roll Back Cemu

  1. Download the version of the emulator you would like to use from Cemu's GitHub: https://github.com/cemu-project/Cemu/releases
  2. Move the downloaded emulator from Step 1 to /home/deck/Applications
  3. (Optional) Rename or delete the original emulator file
  4. Right click the newly downloaded emulator, click Properties, click Permissions, check Is executable

What is the difference between the Proton and the Native version?

Back to the Top

Up until the end of 2022, Cemu only provided a Windows version. EmuDeck bundled this windows version and created a script to run it through Proton. At the end of 2022, Cemu released a native Linux version as an AppImage. The AppImage released in a beta state and still had issues, both with general emulation and game compatibility.

Throughout 2023, Cemu released frequent updates to improve the performance and compatibility of the native version. However, as of May 2023, there are still lingering issues and some games do not run well. These games do run well on the Windows counterpart of Cemu.

EmuDeck only started to bundle the native version of Cemu with EmuDeck 2.1, released in April, 2023. Many EmuDeck users still use the Windows version of Cemu and have not fully migrated over to the native version yet.

The foreseeable future should see improvements and eventual parity with native Cemu and a full migration in EmuDeck from the Windows version.

Cemu Native Game Compatibility

Which Cemu version should I use?

Back to the Top

It is up to you. Both versions of Cemu are bundled with EmuDeck to allow the user to choose. Be sure to read What is the difference between the proton and the native version? as well.

Generally, it is recommended to select Cemu Native over Cemu Proton. There is less fuss with Proton layers and prefixes and the two versions are mostly similar at this point.

How do I know which Cemu is which?
