OK i'll port it soon, i guess it will work as it should.

Edit: OK done porting. Scaler should be set to none. And don't forget it's tweakable.

But if it's to emulate CRT, there must be no horizontal pixel spacing as in the latest pictures. Pixels melting together horizontally but not vertically is what creates the scanlines. But maybe this can be turned off?
Yea most crt shaders have #define variables which can control horizontal or/and vertical blending.


#define SHARPNESS_H 0.5
#define SHARPNESS_V 1.0

#define hardScan -8.0
#define hardPix -3.0
#define shape 2.0
crt-hyllian has horizontal sharpness hack etc.

In my experiance some degree of vertical blending is nice also as it cooperates with scanlines, but yeah, full strength vertical blending does really not feel right.
