Cemu (Wii U Emulator) Cemu is a Nintendo Wii U emulator that is able to run most Wii U games and homebrew in a playable state. Created by Exzap, and written in C/C++. This emulator aims at providing both high-accuracy and performance, and is actively being developed with new features and fixes to increase compatibility, convenience and usability. It was written from scratch and development on the project began roughly early 2015. It requires a GPU that supports OpenGL 4.5 or Vulkan 1.2. The libraries/wxWidgets with GTK interface is both build-time and runtime dependency, webkit2gtk4.1 is not a mandatory requirement. CURRENT=OFF: fix build with vulkan-sdk < 1.4, this option requires build-time dependency development/cmake-opt. If you already had vulkan-sdk from testing/graphics-updates or current branch, you don't need cmake-opt and can set CURRENT=ON.
