Do you have a link to the libretro glsl shader pack? I know the libretro cg shader repo (https://github.com/libretro/common-shaders). But there is no glsl repo on github.

We have converted this repo with nvidia cg toolkit and provide these shaders with an own repo (https://github.com/RetroPie/common-shaders).

Just another question. Is this shader compatible with standard OpenGL? Old versions didn’t work.
