Jobima crt guest advanced presets

[Cyber]

@Jobima

using last guest updates and phosphor-persistence

What’s the difference between this and the AfterGlow parameter which is already included in Crt-guest-advanced?

@Cyber

What’s the difference between this and the AfterGlow?

As far as I know AfterGlow can not be used in the end of preset, also AfterGlow dont fill the interlace gaps but it seems it only fill the edge

more info about AfterGlow and interlace

while phosphor-persistence work whether at the beginning or the end of the preset, also it operates like a real CRT, blindly, and doesn’t skip the gaps between the fields, therefore, its suitable if the goal is to accurately simulate how the interlace system works in CRT televisions

more info about phosphor-persistence and interlace

anyway, I used phosphor-persistence only for “TV 480i” presets, regular presets still use AfterGlow

new update, to use last guest update features

also this update use new crt-black_crush-koko to get better crt-like black levels in bright scenes

EDIT I got it working! Had to restart RA and that fixed it somehow.

Hi.

I’ve been trying to use your shaders but for some reason they fail to load. I place them in the parent directory like instructed. Other presets like sonkun’s work just fine. Did I miss a step?

same problem here.

To add the all-in-1 presets that goes in \shaders\shaders_slang\presets\ didnt work either.

@cuyo01 make sure you update

@sonkun

For this update you will also need guest.r’s latest shader update for my presets to display properly, you can grab it here. Download the " Newest version " one

Installation Guide for guest.r updated shaders:

0. Make sure your slang shaders are up to date by going to main menu > Online Updater > Update Slang Shaders.
1. Download and extract the pack.
2. Go to wherever you have your RetroArch shaders folder and then go to shaders_slang/crt then delete the 5 guest advance shaders in that folder which are “crt-guest-advanced-fast.slangp”, “crt-guest-advanced-fastest.slangp”, “crt-guest-advanced-hd.slangp”, “crt-guest-advanced-ntsc.slangp” and “crt-guest-advanced.slangp” and replace them with the 5 from the downloaded pack.
3. From the same crt folder go inside the “shaders” folder at the top and then look for a “guest” folder, delete that then replace it with the one from the downloaded pack that’s also in the “shaders” folder and that’s it, you’re done. You’ve now successfully updated guest.r shaders.

seems you use d3d* like d3d11, which seems not working at all with TV 480i (except V7 TV 480i) presets (which I think because phosphor-persistence), in that case you should use glcore if you dont have Vulkan

[yyyeeeaaahhh]

Hello, I’ve been a passive reader just checking in for shaders update, I finally created an account for this topic

So I tried to delete the whole slang_shaders to start fresh from the latest Online-update, and some your last update did not work : I see you have implemented the move from …/…/…/crt/shaders to …/…/…/crt/crt-effects/shaders, for crt-resswitch-glitch-koko.slang but it was not done in these 6

guest VFast.slangp

Sony CRT Pixels.slangp

zfast G.slangp

zfast G2.slangp

zfast G3.slangp

zfast V2.slangp

[Jobima]

Hi and welcome

@yyyeeeaaahhh

for crt-resswitch-glitch-koko.slang but it was not done in these 6

guest VFast.slangp

Sony CRT Pixels.slangp

zfast G.slangp

zfast G2.slangp

zfast G3.slangp

zfast V2.slangp

yes, those were forgotten, I will do a silent update to fix them today, thanks for the report

@Jobima

make sure you update

up to 2025-11-16-r1 version.

[Jobima]

make sure to do the #0

It worked, thanks, I almost never update the shaders, only the guest ones.

new update to V8.09

• better gamma
• balanced sharp (PCE and mixed phase now should be closer to Auto, I think mixed mode should act like “notch” with 3 phase content which help getting maximal blending of dithering)
• crt-black_crush-koko removed from 4x presets (it crash retroarch for me)

edit: small update to V8.10

edit: yet another update to V8.11 with better vertical filtering and black level, and as a side effect “TV 480i V8” presets now work better and cleaner

edit: update to V8.12

Do you have an tl;dr for the version differences and the present differences?

[Jobima]

@yuzqailo

present differences

if you use native resolution and dont stream or record use “Jobima CRT Preset TV 480i V8” for NTSC or “Jobima CRT PAL TV 480i Preset V8” for PAL

version differences are basically come from guest changes plus my changes to basically adding more shaders like crt-black_crush-koko and tweak the settings to make the preset work from nes up to ps2 and maybe even wii in balanced sharp and brightness ETC…

Edit: if you mean the V7 vs V8, then you should only use V8 now, I may remove the V7 from the packs soon

[yuzqailo]

Remove the v7, damn, I like it more than the v8. But I sit close to the monitor and prefer the thinner scanlines. I can see why you would remove it though. The v8 has improvements over the v7 and having a v7 is confusing. I do think the o7 is better than the v7.

if you use native resolution

Do you mean running the game rendered to 640x480 resolution, i.e. the window or fullscreen is set to 640x480? Or, do you mean the game is internally renderd at 640x480 i.e. fullscreen but not upscaled internally?

well, you can keep using the V7 if you like it more

I mean if you set the core option to reder the game in 2x or more of the native resolution, I already has a preset for the 4x of the native resolution

That brings clarity to what the 4x is. Thank you. Still confused about what the use case for 480i would be. Would I choose it for content that is interlaced?

all presets can work with 480, but “smooth 480i” will blend Fields using interlace mode #5 from guest

and “TV 480i” will act kinda like how interlace work in CRT TVs

New (Christmas) update 8.14

• V7 removed from the pack (still present in “All-in-1 Jobima Presets”)
• some tweaks and balanced sharping and brightness ETC…
