@Jobima that’s what looking for in RetroArch. More RF preset/shaders if possible please! Those pixels with Rainboweffect always look so nice !
Its little imperfections that make it accurate to the old school experience !

Do you have any presets for RF? I hope we get like something like 97% accurate to it.
I know but I wish we can emulate like that almost perfect from a real CRT

I think we can probably get pretty very close to this using current implementations of CRT-Guest-Advanced-NTSC, NTSC-Adaptive or Blargg NTSC Video filters and presets.

We are almost there. CRT emulation is amazing, thanks to y’all.

Cool trick —> Chroma scaling/bleeding at 0.75 looks good with 3-phase and 32 taps. And NTSC artifacting can also be used without altering the image.

Looks the part! I might have swapped that glow/halation for some magic glow blending into some Base (black) Mask lines.

i remember making this work once in 1080p with the reshade preset once, sadly i lost the preset. Shadowmask for VGA emulation is a wonder
hope the new guy continues from where @DevilSingh stopped at the reshade thread

@Cyber I gave a try to magic glow mask strength and I like how it looks.
From now on I use 0.95 for “mask zoom sharpen” instead of 1.0, it will look better with strong deconvergence values, but this is picky stuff, invisible without zooming the image 
(empty space between the colors).

Thanks,same goes for you 
. That’s a pretty preset you have there, screenshots looks nice.

Excellent! Don’t forget to try to blend it into the unlit phosphor/Mask wires with the Base (black) Mask Shader Parameter for even more realism but only just a slight hint of it though.

hi, is there some new way to control blurring and rainbow in guest advanced ntsc default preset ?
haven’t touched the preset in a couple of months and changed its behavior with current files thanks in advance

With standard content (240p…), blur is already quite strong, de-blurring options are more adequate.
You can play with adaptive sharpening, resolution scaling (can break dithering blending), deblur and standard sharpening. Ofc. there are also filtering controls (sigma…).
With high resolution content i would advise to play with resolution scaling (lower values) and internal resolution parameter to get more blur.
Chroma controls are also available for better fine tuning.
Rainbowing, if set to 1.0 etc. depends on artifacting strength, it’s a good choice to merge fields if making screenshots.
Higher values for rainbowing are alternate modes, more pixels are colored in general if selected.

my bad, for some reason it was not loading properly early on. Now it works as it has been doing for several months.
your presets are amazing ! sorry for the unfortunate comment

Why are the links broken? Never it’s broken on chrome and not on Brave.
Hi, do you think it’s possible to have a 1080p version?

Load the same “4K” preset, change the Mask Type to 6, Size to 1. Make sure the Slot Mask Width is set to Auto or 3 and you might just have to adjust, maybe lower the Slot Mask Height a bit. If Mask Zoom is used you might want to disable or adjust it to your preference.
Also, be sure the Mask Layout matches the subpixel layout of your display.
