[TUTO] Cemu en 2026 : installer et configurer l’émulateur Wii U sur PC (Dumpling, packs graphiques, manette)

Cemu runs Wii U games on PC, often better than the console: here's how to install it, copy your games with Dumpling and set it up properly in 2026.


Which version of Cemu?

The latest stable version is Cemu 2.6 (February 2025), for Windows (installer or portable version), Linux (AppImage, and Flatpak on Flathub) and macOS (experimental, via MoltenVK; Rosetta on Apple silicon Macs). There hasn't been a stable release since, but development continues every week on GitHub: the Receive untested updates option in the settings offers the test builds.
Recommended configuration: Windows 7 64-bit or newer, a graphics card compatible with Vulkan 1.2 or OpenGL 4.5 (GeForce GTX 700, Radeon HD 7000 at minimum), 8 GB of memory, and the Visual C++ 2017 x64 redistributable. Integrated graphics chips are not officially supported.


1. Copying your games with Dumpling

Cemu needs your own games, and a few files from your Wii U for online play. The tool for this is Dumpling (2.7.2), on a hacked Wii U: see our Aroma tutorial. You launch it from the homebrew App Store, from the SD card, or simply by opening dumplingapp.com in the console's browser.
  1. Plug in a USB stick or drive formatted in FAT32.
  2. Choose Dump a game disc for a disc, Dump Wii U applications for an installed game, its updates and its downloadable content, and Dump files to use Cemu online for the console's files.
  3. The files end up in /dumpling/Games, /dumpling/Updates, /dumpling/DLC and /dumpling/Online Files, already decrypted.

2. First launch

The Getting started wizard asks for the language, the folder for your games (Game path), offers Download and configure graphic packs (accept it) and controller configuration. The folder for saves and system files (MLC) can then be set in Options > General settings if you want to move it.


3. Installing updates and DLC

The base game is launched from the list, once its folder has been added. Updates and downloadable content, however, are installed: File > Install game title, update or DLC…, then choose the file meta/meta.xml in the update or DLC folder. Don't open them with File > Load. Some games, such as Zelda Breath of the Wild, need the latest update to run properly.
To save space: in Tools > Title Manager, right-clicking the game, then Convert to compressed Wii U archive (.wua), combines game, update and DLC into a single compressed file. Cemu also reads the WUD, WUX, WUHB formats and uncompressed games (RPX).


4. The right settings
  • Options > General settings > Graphics: Graphics API on Vulkan (OpenGL only for a card with less than 2 GB), and tick Async shader compile: far less stuttering, at the cost of objects appearing with a slight delay.
  • Options > Graphic packs, button Download latest community graphic packs: 1440p or 4K resolution, 60 frames per second (FPS++), fixes. Tick the ones for your game.
  • Options > Input settings: choose the emulated type (Wii U GamePad, Pro Controller, Classic Controller or Wiimote) and your controller (SDL, XInput…). Xbox and PlayStation controllers work out of the box.

5. Playing online (optional)

With the files from Online Files: File > Open Cemu folder and copy into it otp.bin and seeprom.bin; then File > Open MLC folder and copy into it the folders sys and usr. The account is chosen in Options > Active account. Nintendo's official Wii U servers closed in April 2024: online play now goes through the community service Pretendo.


The most common errors
  • “Could not decrypt title” or “This title is encrypted”: the game is encrypted. Redo the copy with Dumpling, which decrypts.
  • Stuck on “Loading…”: corrupted shader cache (right-click the game > Remove shader caches) or incomplete copy.
  • Constant stuttering: Async shader compile, in Vulkan. It decreases as the cache fills up.
  • Vulkan missing or crashes: update your graphics card driver.
  • Objects are missing: a poorly chosen graphic pack; disable them one by one.
