Is there a kind of RetroArch shader repo somewhere?
LOL, yeah!
Thx.
It would be great, if there will be someday descriptions of the shaders in the repo (Like under the Handheld section)?
The problem is: I’m really busy these days and have too much things to implement in some shaders.
I invite you to make those descriptions. And I’ll upload them ASAP.
I would, but I do not know for much of the shaders what they are doing. So I am asking 
Some of the are having comments / descriptions in the source code.
So or so big thx for your efford in supporting this Project!!!
It doesn’t matter if you don’t know about most of the shaders. If you can collaborate at least with those you know the effect, it would be a good start! Just use the gameboy README.md as a model for others.
