New CRT shader from Guest + CRT Guest Advanced updates

New Release Version (2024-10-27-r1):

Notable changes:

  • After some consideration, rolling scanlines are back with a tad different implementation. Some scanline settings and mask combos might produce strange side-effects, but should work in general. Implemented in standard, NTSC and HD versions.
  • Mask Zoom parameter range increase.

It’s one of the less standard effects with crt shaders, but stil present. But i suggest to try it out first hand.

Nice. This update gives me a reason to go tinker with my 4k Shadow Mask presets again.

Edit: @guest.r I think these are good Shadow Mask settings for 4k:

For this image I used the crt mask settings mask 6, size 4, zoom -6 and (transform to) Shadow Mask 1.00.

I think these are the 4k Shadow Mask settings I’ve been needing all this time. I think I’m gonna use them for my next update.

Yeah, 4 * 3 - 6 = 6, so an even number for mask width, which is a condition for a decent shadow mask.

Just mention it, CRT Mask Zoom Sharpen works very well with this mask settings, maybe you want to tweak this aspect also.

Also a decent setting is with mask 12, size 2, mask zoom -8. But you already got a great combo.

Nice. Always good to have new options, I don’t think I tried that combination yet.

I’ve actually just started using a bit of that since my last pack, it seems to work the best with Shadow Mask presets. I notice that setting brings some pixel details out in backgrounds especially in darker areas.

Your shader is so customizable it’s almost insane the possibilities you can pull off. I’ll play around in the lab a bit more then start to get my new pack ready. I’m not tweaking much so this shouldn’t take too long, gonna be a small update just like yours lol.

Higher values ​​for internal resolution combined with horizontal blur sigma at 0.10 can give good results. I did some tests on PSP games and it looks quite good.

I was actually playing with that very setting last night. I raised internal resolution to about 0.30 on my presets messing around, it helps smooth things out a bit more. Even .10 makes a nice subtle difference.

@ProfessorBraun, some nice glowing in there. :smiley:

Otherwise, the Internal Resolution parameter is really nice when the core’s internal resolution is increased. Personally i don’t use other filtering tweaks to hard, since it’s usually right on spot.

For some enhanced looks with the PPSSPP core it’s quite easy to setup anti-aliased scanlines using Internal Resolution parameter and altering some Interlacing params.

My favorites are 3x res + xbrz texture filtering. :face_with_monocle:

Hey thanks, yeah magic glow is very nice ! :boom: I use it on several presets.

Unfortunately when I increase the resolution in PPSSPP it immediately crashes and if I disable cropping it works for a while, than it crashes. But since I like the original resolution it’s not a problem. :grin:

I also use AF 16x on PPSSPP.
