I tested it and looks cool. If you need some testers of new PAL versions, count on me.
I usually like deep shadow masks, like in your stable presets, they hide the pixels and give more texture, but I’m also liking your new presets, with lighter shadowmask but less definition, definitely a different look. Let’s see where you get.
Edit: a couple of real PAL screenshots showing the borders jaggies.
While testing the latest presets, I noticed that the colors on certain systems like Saturn and 3DO look very greenish and completely off. Is this normal?
Im on android, updated Guest Crt and installed Sonkun, but every time i try to load a sokun shaders it says it couldn’t comple resswitch-glitch-koko. What am i missing? Already updated shaders from retroarch.
resswitch-glitch shader has been moved from the 'crt/shaders' folder into the 'crt/crt-effects/shaders' folder some time ago.
It could work for you if you make a copy of crt-resswitch-glitch-koko.slang from this subfolder back into the main ‘crt/shaders’ folder again, since @sonkun’s presets might still be loading it from there.
The catch is that slang shader updates don’t delete files if they are moved or deleted from the main repository. But if someone starts from scratch and updates slang shaders, then presets, which weren’t properly altered, can’t load/work.
When I try to use sonkun’s shaders, it keeps appearing this message:
I did all the recommended steps, I updated the overlays and shaders presets, and I changed my video driver to vulkan. I don’t know what else I need to do… Appreciate any help
Help yourself then! 
guest.r just answered the very same question.
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 tried to replicate one of those to PPSSPP emulator on Android, but i cant make it work on it.
What should i do?
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.
Welcome back! Been looking forward to another update.
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
most of his samples need to be there
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
New screenies:

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.
