Start by visiting the official Cemu website at cemu.info. Avoid third-party download sites that may bundle unwanted software or provide outdated versions. The official site always hosts the latest stable release alongside experimental builds for advanced users.
Download the latest stable version, which comes as a ZIP archive. Extract the contents to a dedicated folder on your system, preferably on an SSD for faster loading times. A typical location would be
C:\Emulators\Cemu\ or similar.
The Cemu
emulator is portable, meaning it doesn't require a traditional installation process. All settings and game data are stored within the Cemu folder, making it easy to backup or transfer between systems.
Initial Setup Configuration
Launch Cemu.exe for the first time. The emulator will create necessary configuration files and prompt you to configure basic settings.
The initial setup wizard guides you through essential configurations including graphics API selection (OpenGL or Vulkan), audio driver setup, and basic controller configuration. For most users, the default settings provide a good starting point.
Select your preferred graphics API based on your hardware.
NVIDIA users typically see better performance with Vulkan, while AMD users may prefer OpenGL initially. You can change this setting later based on performance testing results.
Game Installation Methods
Legal Game Acquisition
Important Legal Notice: This guide assumes you legally own physical or digital copies of any games you wish to emulate. Downloading copyrighted games you don't own violates copyright law and isn't covered in this tutorial.
The most common method for obtaining games legally involves dumping titles from your own Wii U console using homebrew software. Popular tools include disc2app for physical games and ddd (disc dumper) for comprehensive game extraction including updates and DLC.
To dump games legally, you'll need a homebrewed Wii U console and an SD card or USB drive for storage. The homebrew installation process falls outside this guide's scope, but resources like wiiu.hacks.guide provide comprehensive tutorials.
Game File Formats
Cemu supports several Wii U game formats, each with specific use cases and advantages.
WUD files represent complete game dumps including all data exactly as it appears on the original disc or console storage. These files are large (typically 8-25GB) but provide perfect compatibility. WUX files offer compressed versions of WUD files, reducing file size by 30-50% without compatibility loss.
RPX files represent the main executable format for installed Wii U games. When using RPX format, games install to Cemu's mlc01 folder structure, mimicking the Wii U's internal storage organization.
For DLC and game updates, you'll need additional files that install separately from the base game. Cemu handles this installation automatically when you drag and drop update files onto the emulator window.

Async shader compile" to reduce stuttering when new shaders are encountered during gameplay. This setting allows the game to continue running while shaders compile in the background, though it may cause brief visual glitches.
Graphics packs provide game-specific enhancements like resolution scaling, improved textures, and 60fps patches. Access these through
Options > Graphics packs, where you can download and enable packs for your installed games.
Popular graphics packs include resolution scaling options (1080p, 1440p, 4K), anti-aliasing improvements, and FPS++ patches that unlock frame rates beyond the original 30fps cap.
CPU Settings
Navigate to
Options > General settings > CPU tab for processor-related optimizations. Enable "
Triple-core recompiler" for the best performance on multi-core processors. This setting allows Cemu to utilize multiple CPU cores effectively.
Adjust the thread quantum setting based on your system specifications. Higher values (45-100) work well for powerful CPUs, while lower values (20-30) may provide smoother performance on older or weaker processors.
The "
Dual-core recompiler" option exists for compatibility with older systems but generally provides inferior performance compared to triple-core mode on modern hardware.
Controller Setup
Cemu supports various input devices including Xbox controllers, PlayStation DualShock controllers, Nintendo Pro Controllers, and keyboard/mouse combinations.
Access controller settings through
Settings > Input settings. Here you can configure GamePad emulation (essential for games requiring the Wii U GamePad's unique features) and traditional controller inputs.
For GamePad emulation, you can map touchscreen controls to mouse input or configure on-screen touch areas. Many games work perfectly without GamePad-specific features, but titles like Super Mario Maker require proper GamePad emulation.
Performance Optimization Tips
Shader Cache Management
Shader caches significantly impact emulation performance by pre-compiling graphics shaders used during gameplay. Without proper
shader caches, games experience frequent stuttering as new visual elements load.
Cemu automatically builds shader caches during gameplay, but this process causes initial stuttering. Community-shared shader caches eliminate this issue by providing pre-compiled shaders for popular games.
Download community shader caches from the official Cemu website or community forums. Place these files in your
Cemu\shaderCache\transferable folder, ensuring filenames match your game's title ID.
Graphics Driver Optimization
Keep graphics drivers updated to ensure optimal Cemu performance. Both NVIDIA and AMD regularly release driver updates that improve emulation performance and fix compatibility issues.
NVIDIA users should enable "Prefer maximum performance" in the NVIDIA Control Panel for Cemu.exe. This setting ensures the GPU runs at full speed during emulation rather than dynamically scaling performance.
AMD users can achieve similar results through AMD Radeon Software by creating a custom profile for Cemu with power efficiency disabled and maximum GPU utilization enabled.
Vulkan API generally provides better performance than OpenGL, particularly on NVIDIA hardware. However, some games may experience compatibility issues with Vulkan, making OpenGL the safer choice for problematic titles.
Different games have varying performance characteristics and optimization requirements. Here's a breakdown of settings for popular titles:
🎮 Popular Wii U Games Performance Guide
