Adds code/data patching to your games at load-time, which you can activate and share the same way you do graphic packs!.
GamePad input source override for cemu, including full motion sensing support (requires additional software, see the guide).
A nearly complete h264 module for cemu, with an implementation similar to what an official one would be (Cemu 1.15.4 or newer also provides its own alternative).
