A collection of shaders for RetroArch that were ported from CG / GLSL to be compliant with the ShaccCg shader compiler.
There's many differences between how libCg and ShaccCg work under the hood that it's not practical to just patch RetroArch to support loading CG preset files.
For example there's no support for \#include upon which all of CG shaders rely on to manage compatibility between HLSL and regular CG, as well as macros.
It's easier to just port them to this format instead.
You need to install the Pigs-in-a-Blanket build of RetroArch. Then you can just copy all of the contents of this repo to your ux0/data/retroarch/shaders
folder and they should appear and apply correctly. If they don't please make sure you're running the correct RetroArch build, and if they still don't work
let me know by filing an issue here.
In order to trick RetroArch into loading them as if they were glsl shaders. That's currently the best approach and I think it's for the best, to avoid having confusion as to why no CG shaders work at all...
Well naturally @SonicMastr, @frangarcj, @OsirizX, @hizzlekizzle and everyone else who helped out in getting ShaccCg support as well as implementing all of the necessary changes in RetroArch to get it working!
