Custom PPSSPP shaders

[shinra358]

Can't smooth while upscaling...? Even more of a reason to port Guest.r's AA 4.o since it covers AA and smoothing at once
Scaling is turned on in the ini. Using them individually does't make a difference in the comparison to the AA 4.o as to the shots and the goal.
ps: and no I didn't have the main option for xbr turned on with the sub options, so they werent really on.

Edit: nvrmind about the smooth thing and 4.o. Just had to use gauss_sq instead of gauss_s and all was right with the world. Now it's the exact same seems like, depending on the gaussian level.
