Heres basically an unofficial version of the Nintendo WiiU Emulator for Windows:

Cemu Hook v0.5.5.4 is released. A nearly-complete h264 module for Cemu. An implementation similar to what an official one would be. Think of it like a pcsx2 plugin, implementing something not in the core

How to use
Extract contents of zip into Cemu folder

Cemu Hook changelog:
0.5.5.4 - Don't corrupt frames when seeking to another point in video stream
0.5.5.3 - Fix ALL (most?) OF THE H264 DECODING BUGS, add missing dbghelp exports so software relying on them doesn't break
