DraStic

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.

Why is the high-res 3d rendering option slowing the game down so much ???

Thanks bro. But I have already tried it. Just looking for some newer ones like grayscale or motion blur ....
But thanks anyways

I have tried many filters for Drastic but it seemed none of them suited me. They either looked terrible or lowered the framerate. I decided to try as many filters as I can. Any source to download them?
