Hello.
I have recently found desmume and nds4droid source code. There, I also found some great shaders such as hq4x , epx , lq2x and bilinear.
I'm wondering if there's any way to convert these shaders to drastic.

Hqx4 is in there assuming your device can handle it. Though the optimized sabr filter is less demanding and honestly seems to me to be a better filter in general.
