Is it possible to use custom shaders within PPSSPP

[Surperon]

Hey guys,

for almost all emulation needs (except PS2/Wii/Gamecube) I am using Retroarch and have come to enjoy the easymode-crt filter, I use it basically for everything. I really like the look of it when playing PSP games as well, especially combined with an increased internal resolution but as some may know is the PPSSPP Core basically thrown together and a lot of stuff simply not works with it.

So my question, is it possible to get a similar looking CRT shader working/set up within the official PPSSPP emulator? I googled a bit but couldn't find stuff apart from 2 threads which were like 4 years old or so.

Thanks a lot!
