I think that not uptodate maybe it’s from New CRT shader from Guest + CRT Guest Advanced updates and I think it changed to “NTSC/Rainbow Effect (2-phase)” here New CRT shader from Guest + CRT Guest Advanced updates
so sorry, it’s not related to my update, maybe ask guest.r since I will not downgrade (maybe you can try older https://github.com/HelelSingh/CRT-Guest-DX9/commits/main/Shaders/CRT-Guest-NTSC.fx I think what you need is Feb 1, 2024)
