I don't know if something like this has already been made or not but this is a fullscreen smoothing filter with scanlines shader (similar to that of which is on EPSXE with Pete's Opengl 2.9 plugin) that I made. The fullscreen smoothing, scanline thickness, and scanline opacity can all be edited individually to suit each person's resolution/taste. Edited meaning the ability to turn one or the other off/on and the smoothing intensity level, scanline thickness level, and scanline opacity levels.
