Why not increase Saturation/NTSC Saturation as you increase Bleeding?
Obvious reasons, but it increases the color saturation of everything else as well. Like in a big way.
They’re not so obvious to me because that’s exactly what I have done in many of my presets from not too long ago.
Doesn’t increasing the amount of bleeding via decreasing the value of the Chroma/Bleeding or even the NTSC Resolution Parameter decrease the Saturation of everything else as well. Like in a big way too?
Concerning the red, phosphor choice can play a big part in determining the amount of saturation.

@guest.r I just got a new wide gamut monitor (Dell U2725QE ) that supports both DCI-P3 and Display P3 operation.
I’m getting great results with the DCI-P3 profile set on my monitor and in the shader, especially combined with the Philips CRT profile. I was wondering if adding a Display P3 profile in additon to the DCI-P3 profile would be a useful option? My understanding is the difference between them are the gamma and the slightly different white point (DCI-P3: gamma 2.6, DCI white point; Display P3: gamma 2.2, D65 white point).
So yeah, when I use DCI-P3 in the shader and put my monitor into Display P3 mode, the gamma is off and the white point is slightly shifted from neutral (all expected, of course).
I guess this could be useful for people who only have a Display P3 option on their monitor (although I’m unsure if those exist; maybe all Display P3 capable monitors also support DCI-P3 operation). Could be handy for those too who have both options but prefer Display P3 due to convenience (at least the gamma then is very close to sRGB gamma).

Hey! I think it’s a nice idea. I’m also correcting the DCI-P3 white point to it’s standard values (from D65).
New Release Version (2025-06-20-r1):
Notable changes:
- Display P3 gamut support added.
- DCI-P3 white point correction.

While we have interlaced modes 1-4, I don’t think we have an option to only apply VGA Double Scan mode to 480i/p signals without it changing 240p signals too.
This would be desirable. Like as an option for interlaced mode 5, or a setting right next to that so it’s still triggered by the resolution. This would be really helpful for me in games that switch between 480i and 240p. : )

Can you be a bit more specific?
Currently there are many situations emulated, including smart scanline mode if you set internal resolution to 1.0.
I would need specific behaviour for 240p and behaviour specified for 480i.
Guess display wise it’s already nicely covered. Like use VGA double scan when emulating a 15kHz PC VGA display and use interlacing for consumer CRT displays.
If you want double scan for 240p and interlacing for 480i, then it can be covered with internal resolution set to 0.5 in next release.
I think “interlaced mode=0” is what you ask for

I think I was able to balance these things in my last preset update, and yes “The normal US version” is fine, but as I said it’s not only in this game but also in Rambo III (but it’s w not m) and also in the health bar of Castlevania Bloodline
Ah yes! I hadn’t yet tested that on 4K with a 480i signal and didn’t know it did exactly the same thing! Thank you.
And yes, Sega games use Phase 2 so should blend more. You get a health bar that looks like this:
But to make up for it, you get clouds that look like this:
This was it right here. Sorry for my confusion! Like you said, many situations currently emulated! For some reason I just hadn’t realized that’s what option 0 did.

Hey, friends. I’ve been out for like 3 months because my previous PC was power cycling. So, what did I miss? And it’s recommended to download the latest Guest-NTSC- shader? Thanks.

It’s the current state of the rainbowing feature. I might take some more looks into it, indeed.

thanks! seems work fine in cases I already did noted
I did noted another “odd” case with “Clip Saturated Color Beams” and NTSC
that why I avoid using it, seems fine with non-ntsc, To be more precise setting NTSC Chroma Scaling / Bleeding to 1 or lower kinda make it better

Thanks for doing some testing regardless. I’m using Beam Clipping quite “successfuly” with my NTSC presets, but alrightly, they are not getting Dracula’s red eyes look better. It’s a matter of horizontal edge circumstances (mostly) which can be more or less different compared with other presets. Maybe you’ll try some other base ntsc settings some other day which would benefir from Beam Clipping…
