Download Cemu: Nintendo Wii U Emulator for Windows

Cemu is an open-source Wii U emulator that lets you run the console's games on your computer. This page offers the Windows version, plus a quick guide to installing and configuring it. To play you need the Wii U game files (ROM or ISO), which you can find in the ROMs section of this site.

Cemu requirements

• 64-bit Windows 10 or 11.
• A graphics card that supports Vulkan 1.1 or OpenGL 4.5. Vulkan is recommended whenever your card supports it.
• Up-to-date graphics drivers.
• As a reasonable starting point: a modern multi-core CPU and 8 GB of RAM.
• Game files in WUD, WUX, WUA or RPX format.

How to install Cemu step by step

1. Download the file with the download button on this page.
2. Extract it into its own folder, for example C:\Emulators\Cemu. Avoid protected folders such as Program Files.
3. Run Cemu.exe. A first-time setup wizard opens on the first launch.
4. Set the folder where you keep your games in Options > General settings > Game paths, or load a game directly from File > Load.
5. Double-click the game to start it.

Recommended settings

• Graphics: in Options > General settings > Graphics, choose Vulkan as the graphics API if your card supports it.
• Controller: set it up in Options > Input settings. Cemu works with a keyboard, Xbox controllers and other Windows-compatible gamepads.
• Graphic packs: from Options > Graphic packs you can download and enable community packs to change the resolution or fix game-specific issues.
• Sound: if you hear nothing, check the audio section in the options.

Common problems

• Black screen or crash on launch: update your graphics drivers and try the other graphics API (Vulkan or OpenGL).
• Stuttering in the first minutes: this is normal. Cemu compiles shaders as you play and performance improves in later sessions.
• Game missing from the list: check that the folder is added under Game paths and that the file is in a supported format.
