New CRT shader from Guest + CRT Guest Advanced updates

A screenshot of the new feature in use:

Subjectively it can look very nice as well with aperture as with slotmask presets.

RetroGames4K · 9 November 2022 19:09

Looks really good… Is the preset maxed out? Just wondering. I want to use it with slotmask…

guest.r · 9 November 2022 20:02

It’s using some slotmask strength, but not maxed out. New feature also looks good with slotmasks otherwise.

guest.r · 9 November 2022 20:10

New Release Version (2022-11-09-r1):

Notable changes:

(added a new option to clean up / adjust mask-scanline interaction in brighter tones when mask effects is too dominant between two of them)
new feature improvements and optimizations

I was in the middle of tweaking my shaders last night with the previous update now you just dropped another bomb on us lol. Can’t wait to get home and play with this update now.

I 'd just like you guys to know I actually was convinced to make slotmask preset. Mostly because I’m getting sick of reading my own words after I type “Opus”. I need to make some sister presets just so can mention something else.

Here’s an early screenshot. So far I’ve done an initial balancing between bloom/halation and the mask. I haven’t “neutralized” it yet and it’s far from done.

I noticed something when referencing those packs; how often do you guys adjust the bright boost settings? The default settings make a fine preset but Bright Boost Dark’s 1.40 does affect the luminosity range in a very direct manner.

Also @Cyber and I have reconciled.

EDIT: @MajorPainTheCactus’s post here is probably what prompted me to play the genesis version of VR.

HereticZero · 12 November 2022 22:30

I’m sure this has been answered a dozen times, but what does the base default preset have that HD does not?

Should I port every non-NTSC preset over?

guest.r · 13 November 2022 07:15

NTSC version comes with all the NTSC features…

Compared with standard version the HD misses:

raster bloom
smart edge filtering
rolling scanlines
separate bloom and glow passes
TATE mode
automatic smoother filter when swiching to interlaced mode

But the HD version is otherwise pretty much suitable for normal content.

Compared with standard version it has:

more adjustable horizontal filter
fully capable vertical filter (activated with interlaced modes)
is like 30% faster with ‘standard’ content

So if you are doing standard content you can pretty much also use the HD version. Best give it a try first. For increased internal resolution content i prefer the HD otherwise.

HereticZero · 13 November 2022 08:57

I was about to say that the missing TATE mode is the biggest deal breaker. Then it hit me just how much I rely on separate bloom and glow.

If i were to port anything I’d have to give up glow to retain halation.

Not too costly, but my gut tells me to only use HD in a dedicated “image/movie viewer” preset, or something DOS focused. I don’t think I’ll be making either soon though.

guest.r · 13 November 2022 08:58

You can also use it for “Sony” cores, N64 or any other cores which natively output more than 400x300, also with pre-scaling with xBR(Z), ScaleFX…

HereticZero · 13 November 2022 09:06

I’m not really a fan of scalers or raising the resolution. For 6th gen 480i content I keep interlacing disabled. Standard handles it just fine if you ask me.

guest.r · 13 November 2022 09:11

“One does not argue about taste” is an old saying, but standard is indeed quite equipped. Misses an accurate vertical filter though. You can also switch more content to 720p or 1080p…internal resolution and texture scaling are super thingies.

What is the link for NTSC version?

guest.r · 13 November 2022 11:05

NTSC version is included with the regular downloads in this thread.

Somewhat older version is available in the slang/crt folder as a part of the official libretro slang shaders repository.

Hunter_ARG · 13 November 2022 11:08

Cool, thanks…

guest.r · 13 November 2022 15:16

I have also updated @DevilSingh’s reshade port of crt-guest-advanced with the new mask options, it can be found in the top post of this thread.

Highlights compared with “guest-dr-venom” version are better glow, more precise bloom, halation, deconvergence, other improved features…

guest.r · 14 November 2022 22:01

New Release Version (2022-11-14-r1):

Notable changes:

mask boost feature is now ‘edge’ aware
some scanline parameter range adjustments
edit: small feature update

Download link:

HereticZero · 14 November 2022 19:39

Can you go into more detail on those range adjustments?

Or is it a suprise, and I have to wait till I get back to my computer to find out?

guest.r · 14 November 2022 19:46

“Scanline Shape Dark Pixels” went form max 5.0 to 10.0

“Scanline Falloff” went from min 0.25 to 0.2 ( or 1.0/5.0).

Here is also the mask boost feature comparison (before / new):

“Smooth Masks in bright scanlines” previously had a cap of 2. It now has a cap of 1.

I understand if you intended it as a “toggle” effect, but I kinda based my brightness settings around that new feature being set to 2.

it allowed me to ensure Axel’s (Streets of Rage) face was the correct color. If it was set to either 1 or 0 then seemingly nothing could help the matter.

I was about ready to post the config for my high neutrality mask 13 slotmask preset; I can’t now.

It’s probably not fatal, but now I have to find another solution for the mysterious problem that yellows and desaturates the colors in Axel’s face seemingly independently of everything else.

Actually, you know what? I’m still going to post the prototype preset. it might help. just no screenshots; the results wouldn’t be the same.

EDIT: On the plus side the update also seems to fixed some of the issues responsible for the problem to begin with. Readjusting should be quick… relatively.
