IIRC RetroArch on Wii U still doesn't have the filters feature for neither video nor audio filters.Okay, I'm sorry. I'm just a little hasty, that's all. I've uploaded my SD Card files to MEGA. Please check this out.
The only 2 problems are that I don't know how to add filters/shaders (like CRT, Nearest, etc.) and it crashes whenever I quit RetroArch.
I use 1.6.4 (RPX) and only use mGBA, Nestopia, and snes9x-2010.
