you can try to to set
Border to ambient light weight = 30
Border dimming (lights out) = 75

Yeah, that’s another possibility. There are many ways to adjust it to one’s taste.

BTW, @Starman99x, I’ve seen you have a great collection of packs for koko-aio. Is there any chance of some ports to uborder, mainly the arcade ones?

Maybe if I get more time in the future, but that won’t be soon, so I encourage anyone who wants to adapt them for uborder, to do so, but please keep the root folder names identical as they represent the original texture authors (and check the included credits).
You know, I do like that pack but man was it hard to make… I had to use many wildcards to have proper separate params to match the bezel color against some vertical vs horizontal textures, which are referenced inside the Presets-auto.
And there are not many “matching” vertical style textures so I made a separate exclusive Presets-horz folder. As I didn’t want to bother the amazing @soqueroeu with more requests
Anyways, maybe someone else can make an easier configuration, so good luck!
Btw, I particularly like these presets from the pack:

Nope. Integer Scaling is only available for presets with backgrounds.
And prepending a crt shader won’t work with uborder, because the mask grid will be messed up doing that. Any crt shader need a handcraft work to be compatible with uborder.

Whoops. Sorry, wasn’t aware of the technicalities. Thanks for replying!

Hi @Hyllian I hope everything is okay. version 0.3.4 is not on github, right? I found this latest version on Mega, and I just want to confirm that it’s the latest available so I can run some tests.

Hi, I’m fine, thanks. The 0.3.4 I posted earlier is the latest. It has a minor update only, so I didn’t make a new release on github. I’m taking a break on development for some time. The last three months were very intensive, so I’m a bit tired. I think the status for uborder is ok now and I don’t see many changes in the future.

I found working a lot on the presets and shaders can get a little taxing as well. I have slowed a little bit on them as anybody can see as well. Working on a few different things.

Yeah, it’s understandable. To be honest any kind of computer work eventually gives me what I call “config fatigue”.
At least for me, when tinkering too much it becomes a chore, and I end up “doing the chore” instead of playing the games! Like it’s easy to get carried away with improving the experience, and one forgets to have the experience.

This shader you made is really amazing. It works perfectly so far, greatly accelerating the loading speed of the reflection shader and lowering the usage threshold! But I found in the latest version 0.3.3, the three crt-guest-advanced filters in uborder\base_presets\uborder-koko-ambi\uborder-koko-ambi-crt-guest-advanced.slangp fail to load on both PC and Android devices. When you have time, could you please check it out? Also, my RA has been updated to the latest version 1.20.0.Thank you very much!

By the way, I found uborder\base_presets\uborder-koko-ambi\uborder-koko-ambi-crt-guest-advanced.slangp of version 0.3.1 works fine.

Make sure you’re using the latest guest shaders (only available in his thread). The one that comes with Retroarch is ancient and incompatible with uborder.

I am quite sure that I am using the latest guest shaders version. For testing, I placed both the 0.3.3 and 0.3.1 versions from GitHub into the same RetroArch, and the RetroArch version I downloaded is 1.20.0. The only difference is, for the 0.3.1 version , I added the suffix " 0.3.1".

Well, I just downloaded Retroarch 1.20.0, uborder-0.3.3 and latest guest’s pack (from 2025-03-30 in his thread). Unpacked all three and installed from the instructions and everything is working here, even all guest shaders.
You should recheck if you have latest guest shaders installed.
