What Cemu is
Cemu is free software for running Wii U games and applications on Linux, macOS, and Windows computers. The project says most Wii U games and homebrew can run in a playable state. It emulates the GamePad, Pro Controller, and Classic Controller, with partial Wiimote support; keyboards and USB controllers are supported too. Requirements list OpenGL 4.5 or Vulkan 1.2, with 4 GB RAM minimum and 8 GB or more recommended. Intel GPU support is limited, and the project recommends Vulkan for Intel GPUs. Cemu’s graphic packs let users customize aspects of games and can be downloaded from within the application. The software supports most online features, while Pretendo support is experimental and limited to 2.0 experimental releases. Windows releases come in installer and portable formats, and Linux releases are available through Flathub. The native macOS build is experimental and is not considered stable or ready for issue-free gameplay. Users of .wud and .wux games must supply their own decryption keys; the FAQ recommends .wua files, which do not require keys.
