Custom PPSSPP shaders

[LunaMoo]

@Rick1974 you mean those shaders from this post above?
I can't see anything wrong with them, did you edited them in any way?

The only thing which I see that might be potentially problematic with those shaders is the fact that they reuse default fxaa.vsh instead of providing unique copy, so if you changed that file for example by downloading different shader that replaces it or by trying to make your own shader by modifying default fxaa, it could potentially mess things up.

Maybe some graphic driver settings could affect it as well, like some scaling maybe messes up ppsspp coordinates.
