Ah I remember jinc2. I was using that when I was starting to gut out passes from shaders just to add them to guest just to see what it does. I remember using that with guest ntsc and then cranking up the ntsc resolution setting to the max (which gets rid of the dithering), added in jinc2 and I think some other shader just to try and make what I currently have now, a sharp composite preset that still keeps dithering and somehow I got it to work in a way lol. Good times.

I am presenting this shader presentâŚ
Nothing.slangp
Op lacked clarity. From the above I prefer the later rather than the former. There is also a difference in aspect ratio. Idk if there was a difference in the resolutions between the snes and the, wild guess, the arcade version that might have an effect on something.
From above, I canât tell which one is âmoreâ faithful to the original design.

Please hold my L while I figure out how to quote rather than link a post.
Itâs easy just highlight the words you want to quote then automatically you should see the word âquoteâ pop up on your screen. Hit it and itâll appear in a new reply box where you can then type your response directly under the quote.
You can quote as many times in the same reply box by doing the same steps. Just space yourself (hit enter twice) for every new quote you want to add.

As a test I added xbrz-freescale to the NTSC variant. The darker lines feel more illustrative and the extra color noise pulls it towards something more organic.
I also tired adding xbrz-freescale and sgenpt-mix but it mangles to much of the original image.

I tried to adapt a xbrz preset that I have to give a similar vibe
this is my base xbrz4 + gdap
in this I added NTSC colors
this is the same but less saturated to be similar in tone to your screenshot.

I always wanted to ask, do you ever plan to make a updated version of this preset here? This is still one of my favorite presets from you, itâs just wild and crazy and I love it lol.
Hi all. New to this CRT shader stuff. Really like this shader and recently became obsessed with replicating the CRT experience. I wanted to ask how Gamma In and Gamma Out work with our monitor gamma? Letâs say my monitor is calibrated to a relative (effective) 2.2 gamma. Should my Gamma Out be 2.2 as well? And whatâs the point of Gamma In? Should Gamma In match the encoded gamma from the game console?

I wrote about gamma more specifically in this thread, but it was quite a while ago. Absolute numbers donât fit into the monitor gamma scheme as one may predict.
Itâs more about the ratio between input gamma and output gamma regarding your monitor calibration. Ofc. input gamma values between 2.0 and 2.5 are desirable so we can say horizontal blending is done in linear space.
My advice is to leave both gamma values by default if you arenât sure what you are doing. Maybe you can lower output gamma a bit to get more contrast and saturation and thatâs it, more or less.
Because the shaders have other mechanisms which affect this aspect of the image, namely gamma correct, brightboost, scanline gamma, mask gamma, saturation, post brightnessâŚ
I wonât go into detailed explanations here, because one can test the parameter values and how they affect the image by themselves very easily.

Thanks for your reply. I have been enjoying the NTSC preset. It is quite beautiful, but itâs just a bit dark for me at 100 nits. I guess I can just play with the output gamma and brightness parameters and get most of the way there with satisfaction. I appreciate the amount of control made, but some of it is definitely over my head. Thank you so much for your work!

Yeah, seems so. I did fiddle around the last days but couldnât achieve something spectacular different, so⌠Iâll leave it as it is. It looked good before for me and it is still the same on OLED so I guess ânever change a running systemâ. 
Gonna edit my thread as the next step.

There is also another option called âNTSC Filtering Gamma Correctionâ, which regulates horizontal interpolation brightness and is available in latest versions.

I noticed that the under color tweaks the option for crt profiles have six options. I would presume one of them is off but what order are they in?
-1.0 is âmatrix color altering OFFâ, 0.0 is âidentityâ (no-change) processing. Then you can start counting profiles, the order in the parameter description matches the corresponding color profiles.

When eyeballing -1.0 and 0.0 I donât see a difference between the two. So if 0.0 is disable then -1.0 is?
0.0 isnât âdisableâ, itâs neutral matrix processing (identity) with default settings, which also allows âpriorâ color space alterations.
-1.0 completely bypasses matrix color processing, as well color spaces alteration as color profiles.

Iâm curious if anyone that is creating presets with guest.râs shader uses the downsample feature. I;ve been playing around with a lot of the options and I really like the look of the games using guest.r NTSC and then downsampling. It creates an image that I feel like Iâm much more familiar with on my old TVs. I really enjoy it and I hope that guest.r keeps it as part of his shader. Iâd like to know if anyone else who creates presets is using it and what they think about it.

Hey there!
âDownsamplingâ with the NTSC shader makes good sense, as it is primarily a feature which works very well with higher resolution buffers and the ntsc buffer horizontal size is more or less already hi-res.
And no worries, the feature is very fast and useful, Iâm not considering removing it.

I finally got a chance to post these screenshots which I had liked over at r/crtgaming

Somewhat predictable replies, itâs tough to appreciate these things sometimes without playing with them for hours and becoming intimately familiar with their limitations. Most probably donât know the struggle of trying to make composite video look sharp, balancing the mask with brightness, etc.
Well, I just took the plunge and purchased a used RTX 3090 so Iâm on way to 4K. The actual monitor is whatâs bugging me now; I feel like 4K gaming hasnât really arrived yet in terms of the availability of both the GPUs and the display devices. Getting off-topic, thoughâŚ
