Cemu 1.19.0


Cemu is a Highly experimental software to emulate Wii U applications on PC.


  • Can run encrypted Wii U images (WUD) and RPX/RPL files
  • Internal resolution is 1920x1080 (if supported by game)
  • Contains basically no optimizations. Expect slow framerates and long load times.
  • Windows 7 or above (x64) (other platforms may be supported later)
  • Requires OpenGL 4.0
  • Tested on NVIDIA and AMD: Runs fine on most recent driver
  • Tested on Intel: Garbled output but runs if OpenGL version is supported


Cemu detailed changelog for 1.19.0


New in 1.19.0d:


  • Vulkan: Fixed an issue where async pipeline compilation could block the render thread. This should reduce stutter even further when async compilation is enabled.
  • OpenGL: Fixed 'Compiled x shaders...' notification not showing since 1.19.0.

New in 1.19.0c:


  • Vulkan: Tweaked sync/async decision algorithm Async shader and pipeline compilation should no longer break Splatoon ink mechanics.
  • Vulkan: Fixed a bug that caused Xenoblade Chronicles X character models to be broken on Nvidia Vulkan beta drivers.
  • Vulkan: Fixed a texture leak which could lead to performance slowly degrading.

New in 1.19.0b:


  • general: Fixed crash that could occur during the shader cache loading screen.

New in 1.19.0:


  • general: Updated language files.
  • Vulkan: Added experimental option to enable asynchronous compilation of shaders and pipelines. This option trades stutter vs emulation accuracy.
  • Vulkan: Fixed an issue where depth clear operations on newly created textures would be skipped. This fixes lighting issues in MK8 and Splatoon.
  • Vulkan: If supported by driver use VK_EXT_custom_border_color to emulate arbitrary sampler border colors. This fixes grass LOD transitions and other more subtle issues in Breath of the Wild.
  • Vulkan: Tweaks to shader & pipeline compilation counter overlay.
  • coreinit: Fixed FSGetMountSource correctly iterating devices when called repeatedly (#292).
  • gfxPack: Added support for specifying "default=1" to select a default preset per preset category (#283).
  • nn_acp: Implemented ACPCreateSaveDirEx().
  • nn_act: Added support for persisid.dat which handles the highest used account id.
