Cemu - Wii U Emulator

Cemu - Wii U Emulator is an experimental program to emulate Wii U applications on your Windows PC!

FAQ

Controller input
Currently, the DRC (GamePad), Pro Controller, and Classic Controller is emulated. Wiimotes are emulated as well (including native support). Keyboard input + USB controllers as input devices are supported. GamePad touch input can be controlled via a left mouse click. Gyro functionality is emulated with limitations and can be controlled via the right mouse button.

Which controllers are supported
The GamePad (DRC), Pro Controller & Classic Controller can be emulated, which can be mapped to either your keyboard or any USB controller. It currently supports DirectInput and XInput.

How can I see the GamePad (DRC) screen
The GamePad (DRC) screen is rendered into the main window of Cemu while holding the TAB key on your keyboard or by mapping it to a controller button. You can also toggle between the screens by pressing CTRL + TAB. Additionally, the GamePad view can be displayed in a second window.

Does sound work?
Yes, mostly. But be warned, some sound effects and filters are not yet supported and there can be sudden loud noises in certain games.

Is there support for online functionality?
Online support is almost non-existent and will work only in applications that rely only on very basic network functionality and require no server authentication. This currently only includes the Wii U web browser and possibly some homebrew applications.

Will other platforms besides Windows be supported?
Multi-platform support is planned and so far many development decisions have been in favor of supporting multiple platforms (e.g. choosing OpenGL over DirectX for rendering). But currently, there are thousands of other little things that need to be done before work on ports can be started.

Why is Cemu so slow and will performance ever improve in the future?
At this point, the app can already be considered highly optimized and possible future optimizations will only arrive in small and incremental steps. Keep in mind that emulation always requires a high-performance system compared to the emulated system. For Cemu, the single-core performance of your CPU (and by extension RAM speed) is the most important factor for full-speed emulation.

What are game profiles?
Game profiles are text files that can be used to set up game-specific configurations in the program. You can find game profiles in the 'gameProfiles' folder of Cemu - Wii U Emulator. There is also an example.ini explaining the available options and how to configure them. Note that some 'expert options' are only available via game profiles but not via Cemu's GUI.
