Custom PPSSPP shaders

[Demetrius]

Hello!
I'd like to ask the Development team about this:
is there a chance to have cg, glsl multipass (to be able to use cgp) shaders support?
I saw tons of awesome retro shaders in the internet and especially for Retroarch. Would be great to have the ability to use them with PPSSPP itself, cuz PPSSPP integration into Retroarch is really baaad currently
I read about glsl convertion but actually this is a really messy way for a simple user. And still it allows only 1 pass shaders AFAIK
