First post here, so Hello everyone!.
In latest days i've been playing with glsl and shaders.
I never used them before, nor i wrote any shader before, so probably i did some mistakes/unoptimized code, did something already existed, whatever, i don't know.
Anyway, by inspecting other's people code, i came up with a shader that looks good to me; also is very configurable,and i think it is a nice toy to play with.
It has support for several features:
* non linear scanlines on original coordinates
* non linear screenlines on screen coordinates
* custom rgb masks with(out) offset
* glowing,haloing,blooming
* gamma correction
* saturation correction
* alternate blanking (like uae's feature)
* play nicely with FS-UAE's autoscale function
Also, it is important to know that it is meant to be used with:
*
line doubling enabled: line_doubling = 1
*
low resolution disabled: low_resolution = 0
I've set the default values to match my real arcade crt monitor as much as i can on a 1080p, you may have much better results tuning it for 4k, of course .
Please, share your impressions, ideas, improvements...
Latest version is 1.42, not (yet) made any screenshot, you can download it here:

Screenshots for 1.42 here:
http://wpage.unina.it/aorefice/share...2/screenshots/
In 1.42, files are named with the scheme:
Code:
FeatureX-1.FeatureY-0-....-FeatureZ-string.shader
where 1 and 0 means that that feature is present or not, "string" describes how that feature has been configured.
Eg:
Code:
scanlines-0.glow-1.vmask-full.darklines-offset.halo-1.bloom-0.shader
...means that you get no scanlines, full vertical mask, darklines painted with an offset, halo and not bloom.
The following reflects an outdated version, see screenshots for 1.42 instead.
