Custom PPSSPP shaders

[LunaMoo]

Sorry, didn't notice earlier.

Anyway for motion blur, PPSSPP currently exposes previous frame to allow simulating ghosting of the original PSP <=2000 screens. As far as I can tell the shaders you're mentioning are doing just a basic blend between past frames with a drop off and are in no way difficult to write from 0, however they can't be written without exposing higher number of past frames in PPSSPP which due to lack of demand isn't a thing as of now, I guess enhancements typically concentrate on disabling motion blur in games that has it than the other way around^_^;.

Edit: I don't suffer from much free time recently, but opened a feature request on github, hopefully it will interest someone enough to implement this.
