Hi, this shaders can work on a mini pc that has integrated graphics?. Like for example: -Intel Lake N100 – SSD 256 GB – 8 GB RAM DDR4– Intel® UHDGraphics. -RYZEN 5 PRO 3500U – SSD 512 GB – 16 GB RAM DDR4- Radeon Vega 8 -RYZEN 7 PRO 3700U – SSD 512 – 16 GB RAM DDR5- Radeon Vega 10 -RYZEN 9 4900H – SSD 512 GB – 16 GB RAM DDR4- AMD Radeon ™ Graphics
Hello everyone. I also want to confirm that these sonkun presets are failing to load for me as well, and I’m getting the same error message as above: “Failed to apply shader preset crt-resswitch-glitch-koko.slang.” I tried moving crt-resswitch-glitch-koko.slang to its old directory as guest suggested and still no luck. If anyone knows a fix, please let me know. Thanks!

For anyone else having issues getting them to work I did a find and replace using vs code in the sonkun folder:
This appears to have fixed the issue for all presets I have tried.

Hello, Thanks for your work.

I have fixed @sonkun’s presets, affected by the res-switch shader file location change.
Here is the download link:

Does this mean I can update the shaders to the latest? I’ve been avoiding it since I mainly use Sonkun’s presets.

You can update the shaders through the Retroarch updater or use the latest revison. Have tested it and the presets work nicely.

Awesome, thank you! Last question: I noticed you named the pack “2025-01-14” but Sonkun’s latest are from 2025-01-27. Did you have to use an older version, or is it just the name that is different?

You are right, there was an even newer (the latest) version:
Here is the download link (fixed presets):

Yo everyone, I return once again bearing new updated gifts. I already snatched up the latest guest.r shader update and went straight to work. Continuing right from my last sample pack I tweaked a few things around and this may be my new potential look for my next release. Try them out and see what you think.
I also fixed that res switch issue as well.

These samples use the latest guest.r update so be sure to grab that here and install before using my presets.
Unzip the folder then move all presets directly to the root shader folder before using.
@guest.r thank you for putting together that fixed release a few posts above, I didn’t realize last time I was here that the location of the res switch shader got moved causing those errors. I also really appreciate that new “show original image” setting you added in, let’s you see what’s going on in real time to help tweak things.
Cool as hell to see how the ntsc shader blends all those dithering effects side by side to the raw image.
Edit: Did a small retweak to the pack and put a new one up so if you already downloaded it please regrab it swap out those presets.

Tried everything to get these to apply on my Ayn Thor and nothing works. I changed the folder location to one that isn’t sandboxed, I updated the slang shaders and the guest ones manually, I put the sonkun folder in the shaders_slang folder and I always get “failed to apply.” The only thing I’ve managed to get to work is the new sample 1080p-composite-slotmask.slangp shader and that will only load if I put it in the root “shader” folder next to the shaders_slang folder. If it’s inside the shaders_slang folder or any other it won’t apply. None of the other profiles load regardless of where I put them. Would greatly appreciate if anyone can help, I feel I must be missing something

That previous upload was me getting my feet wet again, been a while since I tweaked anything. Moving right along I went back into the lab to play around some more while I take you all along on my journey with me until my next actual release

Same as last time, place all presets directly into the root shaders folder not shaders_slang.
Yo, long time no see. I’m glad to be back, this time I’ll be around more frequently, was gone dealing with a bunch of stuff taking time away from playing in the lab but I’m back now.
There’s probably a good chance my preset pack doesn’t even work anymore since a few things got switched around since that release, I’m working on fixing all of that when I release my latest pack, I apologize for the inconvenience. In the meantime you came at the right time to see what I’m working on now to replace that old pack with, you should try out these samples and get a sneak peak. You’ll have to download this guest.r release for them to work though. After that grab my samples above then instead of placing them in the shaders_slang folder simply place them in just the shaders folder and they’ll load up from there. No HDR or other extra brightness settings on your TV needed, my presets are extremely bright already.

Thanks for the feedback. I’m assuming you mean the mountains are too “reddish”. Loaded the game up real fast and right away I knew which setting was mostly likely causing it, the “red-green tint” setting in grade.
Here it is using the sample pack from above:
Here’s after tweaking that setting and raising it up one value below 10:
I split the image between raw and shader to show it more. Is that what you were talking about?
Edit: Ran another test in a different area and yeah that setting for sure needed to be tweaked. Here’s before and after in the window area with the sky:
No, that’s not it at all. Look at the outlines on the green parts of the mountains.
Here’s a clean image:
Here’s one of your previous presets: Finally, here’s the latest standard stock guest:
Your preset is creating colors out of thin air! That’s what causing my concern.

Hmm I think I may know which setting is doing that, possibly the “Mitigate Mask on Edges” setting perhaps?
Here’s with it on:

You meant that? Also you indirectly helped me as well as I didn’t like how those mountains were looking, too reddish looking so I made it look more how it looks in the raw image. I’ll be putting out a new sample pack with that change as well.
