Custom PPSSPP shaders

[Ritori]

Edit:
Oh and while it's pretty impossible to make a shader looking good in all games on default, looking at this - https://github.com/hrydgard/ppsspp/pull/4018 we should soon have custom shader support in PPSSPP then we'll be able to just copy a shader file with different config name it as we want and end up having few shaders to easily switch between for different games needs.^^

That great I can't wait to test all shader you make
