CRT-Guest-Advanced, HD and NTSC for ReShade!

On another note, I have been having an issue with DX9 games where the resolution will not scale correctly unless I use downsampling. For some reason, games like Sonic Mania, Sonic Forever, and Sonc 2 Absolute will have a line of distorted pixels in the center of the screen when they are set to their base resolution of 424 x 240. Setting a multiple of 240 and using y-downsampling fixes this issue, but it can interfere with blending. Lowering the resolution scaling of the x and y resolutions can fix that, but be gentle with it. You can easily over-blur the image. Go little-by-little until things like the waterfalls look right.

The same issue has been happening to me whenever I use the most up-to-date version of the DX9 shaders and have phase set to auto or 2-phase. Manually switching to 3-phase or mixed phase fixes the issue. I do not have the same problem when I use the other version.

What I was trying to say is the fact, I can’t replicate the Sonic Rainbow + Dithering on Sonic Mania. These small rainbow artifacts on the vertical blue shades in Sonic Mania are so wrong.

Either Phase 2 or 3 don’t fix the issue to me.

What other version are you referring to? Please

OK, for the rainbow effect you are meant to use the the “ntsc coloring/rainbow” setting near the bottom of the ntsc settings at the top of the guest-nstc shader settings (it’s a bit confusing, I know). If that is not enough, you can use the custom nstc fringing and artifacting values at the top of the settings. Apologies for the delay, I have been swamped with school . Let me know if you have any other questions.

thank you. Enabling ntsc rainbow in options its exactly what i show in 2nd picture:

Hello. I’ve recently tried CRT guest NTSC for ReShade project by using it on Sonic Mania. Are there some missing files or updates in that package in order to get the same Dithering nor Rainbow banding such as the Genesis/MegaDrive Sonic games ? … or is this an issue being related to how Sonic Mania was actually drawn with its waterfalls? I just end up getting: [sonicMania1] [sonicMania2]

Still waiting on a Gdapt/Mdapt Reshade conversion to compliment these CRT shaders. NTSC and GTU shaders blur the image far too much to achieve any desirable level of dither blending.

NTSC and GTU shaders blur the image far too much to achieve any desirable level of dither blending.

I’m not familiar with the differences between the Reshade versions and the RetroArch/Slang versions of CRT-Guest-Advanced-NTSC in terms of output and functionality but if it is essentially equal and you’re not able to achieve blending and transparency without excessively blurring the image then perhaps you’re doing something wrong?

It might help all stakeholders if you would post some screenshots as well as the parameters you’ve tried so far.
