Hi, this is a very old version of crt-hyllian, BTW. I’d like to reproduce that blur you mention, but couldn’t do it without details about how are you using this shader. Can you provide a step-by-step way to reproduce that blur and show some screenshot showing this explicitly?
If you’re not following latest updates on slang repo, I made a big update on crt-royale-fast shaders and presets: https://github.com/libretro/slang-shaders/commit/0a305b879eec074f9d620282293844c7a878fb60
- Toned down Gamma and Brightness compared to default Royale;
- Deconvergence is back. Figured out that using vertical subpixels deconvergence mitigates uneven scanlines in non-integer vertical scaling. Works great at 1080p!
- Added geom’s curvature;
- Updated crt-royale-fast (inside crt folder);
- Updated crt-royale-ntsc-composite-fast (presets folder);
- Added new presets: crt-royale-pvm, crt-royale-pvm-shmup, crt-royale-pvm-blend, crt-royale-pvm-ntsc-composite (presets folder).
crt-royale-pvm:
crt-royale-fast:
crt-royale-pvm-shmup (using integer scaling and 4:3 aspect ratio):

Made a small update to get even better scanlines at non-integer scalings: https://github.com/libretro/slang-shaders/pull/633
They’re called pvm for a reason. Can you spot extreme scanline thickness variation in these screens? And the mask popping in red regions?
If you didn’t notice, those snaps were taken at a non-integer scaling (1080p), and yet, the scanlines don’t look uneven. It’s very rare to notice any uneveness with this preset.

Thanks for the updates, bud.
Do the NTSC composite presets actually have the last update from guest.r by the way ? Assuming these presets are using the code from him for the rainbows
Lately, guest.r could fix an unsuspected bug with the rainbow not being shown up properly. Suspicion is about a relatively recent update on ntsc-adaptive. But could be wrong. Still, he fixed it up just recently.

Yes, those presets use the ntsc-adaptive with three passes, so if you update them most certainly that bug will be fixed.
they’re updated already. The fix works on CRT guest NTSC preset but it not worked on your crt ntsc pvm composite or the crt royal composite presets
Ok, i didn’t test, so suppose I’ll have to update some var name or other things. Tomorrow I’ll look what has changed.

have a good night and thanks for your presets!

Nice! BTW, I just updated my shaders RA 1.19.1 and then downloaded and copied latest guest’ shaders (because repo isn’t updated yet). And all worked as expected.
Some screens:
Obviously, those strong rainbow only appear on stills. When the frames are updated, They give a nice stroboscopic effect that looks like the screen is blinking.

CRT-Guest-Advanced-NTSC’s NTSC component is not identical to NTSC Adaptive. It was proposed to replace it but the NTSC Adaptive was updated in a different way instead, only taking some of what had been updated in CRT-Guest-Advanced-NTSC while leaving other aspects intact most likely for compatibility reasons.

Yeah, I know. And the two ntsc presets I posted (crt-royale-ntsc-composite-fast and crt-royale-pvm-ntsc-composite), both point to guest’s ntsc folder. So, if you update your guest’s folders, those presets will point to the correct shaders.
I mean, if the fixes are all contained in those three ntsc passes. Otherwise, then no.

The problem with this method is that after you’ve perfected and are satisfied with the look of your shader preset, it is only one update or major change away from at best not looking as intended and at worse looking completely broken.
Both @Azurfel and myself have subsequently resorted to copying whatever version of the CRT-Guest-Advanced-NTSC shader was used for preset development into its own dedicated folder in Slang_Shaders where Online Updates won’t mess with it.

I understand it may be the case. But for what I’m pointing, I doubt it’ll have a big change in the future to compromise ntsc visual. Even if that happen someday, I’ll just point to the default ntsc-adaptive folder as I think the differences are negligible in most cases.

If you didn’t see the first screenshots in other thread, this is an update. I’m working on cleaning royale-fast’ slotmask and turning it into BGR. The first version was a bit too green. Now I fixed the green bias and intend to insert this option as a new mask at crt-royale-fast (I won’t change default royale):

Ok, at last, It’s now available through the repo: https://github.com/libretro/slang-shaders/tree/master/presets/crt-royale-fast
I made a bunch of shaders, for 1080p and 4k. Those ntsc-composite are made to work with @guest.r’s ntsc-adaptive 3-passes shaders. So, I suggest that you update them too, just download the latest from guest’s thread and update them.
I recommend you to update through update online, because LUTs are udpated too.
Genesis has two composite presets, one for rainbow effect and other for regular effects (works with sega master system too). Composite for psx can be used for Saturn games too. Artifacts/Fringing quality decreases in this order: psx > snes > genesis > genesis-rainbow-effect.
Screenshots, mostly using composite-slotmask (my favorite now):

Did you integrate with koko-aio or other?
