Thanks a lot for updating the port!
I’m getting some kind of moire effect with mshift = 1.0. No matter the preProcessor resolution, on a 1080p monitor I see moire on certain dark spots when an image moves (on Resident Evil 3 FMV, moving the camera around in Thief 1-2, System Shock 2, Serious Sam 1-2…) Is 1080p too small for a proper Shadow Mask?
Your best option for “mshift” and 1080p is to use mask 10 without any mask size changes or mask zoom.
Alternate and finer options are mask 0 or mask 5, or maybe mask 7.
Thank you so much for this. I’m using the reshade files with GOverlay/VKBasalt and Lutris and it all works beautifully.
test updates (to the last crt-guest-advanced) https://github.com/Jobima1st/CRT-Guest-ReShade/branches and https://github.com/Jobima1st/CRT-Guest-DX9/branches
Thank you so much for keeping the reshade port up-to-date!
Updated the shaders to the latest (crt-guest-advanced-2025-06-09-release1) version!
A big THANKS! to @guest.r for helping with and testing the shaders.
CRT-Guest-DX9 (Seems like some games still need this.)
(Tested with DirectX 9/10/11/12, OpenGL and Vulkan games/emulators on a RTX 4070.)
These pics are too sexy.
hey hi, do you know why do i get this message while trying to load crt guest advanced ntsc ? The game uses DX9
This should work - CRT-Guest-DX9. And if you don’t mind - Are on an AMD or Intel GPU by chance?
This is the best I could get to achieve NTSC rainbow in Sonic Mania. Unfortunately, it may need more advanced shaders modding to get a proper result.
Dithering works Ok with some other shaders around.
Thanks for updating those guest shaders to most recent versions, though
First. See if turning Performance Mode ON in ReShade after you do the settings help.
If that doesn’t work post your settings here, so I can test them on my end.
EDIT - Sonic Mania with CRT-Guest-NTSC. Rainbow Artifacting set to 3.0 -
Performance MODE OFF -
Performance MODE ON -
hey @DevilSingh thanks buddy, you’re too kind for the help.
Yeah, the dithering is possible with guest NTSC.
What I’m looking for is also the addition from Rainbow NTSC effect. Like on Here:
This game I know its not 4:3 aspect ratio but rather, 16:9 yet still would like to get this effect for that game, even if its not based on the original Genesis console.
Hello everyone. How do I install these three shaders and where do I copy the texture folder?
Thanks for your continued work on this.
I adapted your ReShade port of the HD variant to Duckstation last year and fixed a few bugs as well (probably conversion bugs that were introduced when moving to ReShade). Maybe you fixed those already in your new version, but I just thought I’d let you know, maybe you wanna take a look 
UPDATE - Several Fixes for all the shaders.
@ynnad4 can you check if NTSC Coloring/Rainbow Effect (2 Phase) works for you now.
It’s working on my end -
See if any of these two work (just copy & paste them into CRT-Guest-NTSC.fx) -
And make sure Performance Mode is ON in the ReShade menu.
