New CRT shader from Guest + CRT Guest Advanced updates

[RetroGames4K]

@Cyber

That doesn’t look like trying to me! Looks like you’ve done it!

Wow! Thank you I lowered Mask bloom and raised halation just a notch as you mentioned, and also I made changes in deconvergence mode, it was quite a bit messy before.

Hmm I never considered that setting cause I had it turned off this whole time, I guess that still had an effect on the saturation then. But yes I think I’m able to get by with this new found workaround, that was one of the last things I needed fixed too.

[Superdonkeyjack]

Can I copy and paste these values in retroarch or do I have to type these myself?

[Cyber]

You’ll have to copy the preset then paste it in a text editor like Notepad. Then remove all the "> " before each line then save as a *.slangp in your Shaders folder.

Be sure to match the version of CRT-Guest-Advanced being used in the preset.

[Superdonkeyjack]

I’m sorry, Cyber but do I have to copy these on like a notepad and then replace “>” before each line then save as a *.slangp in my shaders folder?

[Cyber]

Yes. That’s what you need to do. Don’t forget the space after the > as well. The formatting should look like Professor Braun’s preset above.

New CRT shader from Guest + CRT Guest Advanced updates

@Cyber I gave a try to magic glow mask strength and I like how it looks. [image] [image] From now on I use 0.95 for “mask zoom sharpen” instead of 1.0, it will look better with strong deconvergence values, but this is picky stuff, invisible without zooming the image (empty space between the colors).

[Superdonkeyjack]

I did something wrong. It’s not loading in Retroarch.

[Cyber]

Give us a ball by ball of what you did including photos and screenshots so that we can understand where you’re going wrong and correct if necessary.

[Superdonkeyjack]

What’s a good website to display images from screenshots?

[Cyber]

Postimg.cc and imgbb.com are excellent in this regard. I used to use imgur.com before but I can’t figure out how to stop it from recompressing my images and significantly lowering their quality.

Greetings @guest.r!

Can support be added for this new OLED subpixel layout to the CRT-Guest-Advanced family of shaders and would it be a trivial task if possible?

OLED subpixels. How do they work?

New Subpixel Layout/Order confirmed for 2025 LG Display RGB Tandem OLED display panels. Might also apply to other RGB Tandem OLED displays already on the market. LG also changed the subpixel layout. Instead of the RWBG layout they’ve been using since they first introduced their OLED panels, the G5 is different. It looks to be an RGBW layout, but the first subpixel is blue, so we’re classifying it as a BWRG layout. If you want to see a closer look at this new subpixel arrangement, we took a vide…

Thank you. Also, has anyone encounter an issue where RA isn’t saving your shader preset? I like to use certain cores and with something like the GB/C/Adv; I got my content directory. It keeps not saving it, sorry for going offtopic.

shader - save presets - save core presets

[Superdonkeyjack]

I usually do it with save content directory because I love to use Sameboy with both GB/C cores. So, saving with core will have play GB/C games with either GB-DMG Shader or GBC shader, when I want it specifically want for GB/C separately. I think it just doesn’t want to save content directory for some reason.

Step 1: Organize Your ROMs

Make sure your games are in two separate folders:

• /roms/GameBoy/ → for Game Boy games
• /roms/GameBoyColor/ → for Game Boy Color games

Step 2: Set Up GB Shader

1. Launch a GB game from /roms/GameBoy/
2. Open Quick Menu → Shaders → Load your preferred DMG-style shader
3. Go to Overrides → select "Save Content Directory Overrides"

Step 3: Set Up GBC Shader

1. Launch a GBC game from /roms/GameBoyColor/
2. Apply your GBC shader (or leave it as-is if you like the default)
3. Again, go to Overrides → "Save Content Directory Overrides"

[Superdonkeyjack]

I did everything except the overrides. I didn’t know it play a major role in that. Thank you.

[Superdonkeyjack]

Yea, it is still not working. Idk why and it did the same with my last RA which was 1.17, I think. Idn what is going on.

Hey! I can’t say anything certain without a tester, but it’s quite possible that the default layout will be suitable, since white subpixels aren’t anything new with OLED’s.

Some while ago the BGR layout was ‘blue pixel first’, but it didn’t work out to well with slot masks, so i changed it back to RBG for a current whole pixel.

It might work out with the new OLEDs as well if we push red subpixel to the beginning.

If testings prove differently, then a new layout could be inserted. Lots of room for this regarding parameter values.

try to go to :

../config/core_name/

delete all shaders related files (.slangp)

then re-do the saving procedure

Load game -> load the shader

then

Shaders -> Save Preset -> Save Content Directory Preset

(there should be no need to save any overrides…)

[Superdonkeyjack]

Worked like a charm, thanks and sorry for being way offtopic.
