Decaf is an open-source Wii U emulator for Windows and Linux. It is known to be the very first Wii U emulator ever released. It's currently in the early stages of development but can successfully boot several commercial games, albeit slowly with many glitches.

Overview[edit]

Decaf received some major updates in late 2018 / Early 2019. A Vulkan renderer and a qt interface have been implemented. A Discord server has been started which allows better communication between developers working almost exclusively on decaf and developers from other emulation projects. A lot of games are now working and reaching playable speeds as well as correct graphics.

System requirements[edit]

Like Cemu, Decaf has high system requirements.

  • OS: Windows or Linux, 64-bit
  • GPU: OpenGL 4.5+ or Vulkan 1.1.92.1+

Issues[edit]

This emulator doesn't clean up allocations for textures and shaders, which can cause some issues (stuttering, crashes) after around a couple of hours. One possible solution right now is to periodically close the emulator.
