Potato CRT+Composite shader for PSX?

Hey guys,

I have all my cores up to PSX set up with easymode + blargg composite. Tried messing with some shaders to get the same look in PSX but I end up with 6 levels of shaders and a speed problems (and the need of enabling threaded video).

Do you guys know of a potato way of emulating crt dots like easymode with the addition of some bleeding like blargg/ntsc?

Thanks!
