So i'm currently running Vice64 on the Firestick 4K and it works great. Sonninnos has done a fantastic job on this Retroarch emulator. It used to be unusable. I tried a couple of shaders for it. A popular fast shader being 'crt-pi'. Unfortunately it seems to make the whole right side of the screen a greenish colour. I also tried a couple more, 'zfast' was one of them and it did the same thing, half a green screen. I don't know if this is my TV or because of the PowerVR graphics not supporting something in the masks. Has anyone else tried using these shaders on Retroarch Firestick and experienced the same thing or is it just me ?
