Thanks. I scanned though the crt sub folders and found some more shaders, but for me, only “crt-interlaced-halation” has curvature. It’s slowing the system down a lot as predicted, but this is on my 1280 x 1024 display. Might work better on the small 320×240 lcd Ive ordered. Btw, can you edit the curvature in crt-interlaced-halation? I would like more symmetry, not like the default, which is wider down the bottom(as your screenshot)

Or could you give an example of another curvature shader, cause for me, crt-interlaced-halation is the only one with curvature?
