Bitman's Uborder Presets

Uborder Preset Collection

Uborder

Uborder is a shader that can run on modest hardware. It’s intended as a faster, simpler alternative to Mega Bezel and Koko-aio. It allows you to port your own overlays easily.

Uborder shaders

Uborder shaders Latest release: Uborder-v0.1.0 Blur refletions done in linear gamma; Added a param to control blur reflections quality/performance. What’s this? It’s a simple and fast alternative to more complex bezel shaders like Mega Bezel or Koko-aio. Why? I really appreciate the features offered by Mega Bezel and, more recently, Koko-aio shaders. Being complex shaders, they tend to require a powerful machine to run. This made me wonder if it might be possible to create something simp…

Collection

Since it’s relatively simple to create presets, there are already a number of choices to pick from. Besides Hylian’s own packs, one of them is @Boz1978’s, that includes edited Retrolust Arcade overlays:

Another is a few of my own presets:

[Generic arcade]

[70s Night]

[90s]

[koko-like]

[Generic Arcade - Vertical]

Installation

1. Download whichever you want:

Generic Arcade:

https://mega.nz/folder/aegwmKBA#a6hCwasJThG-01GqxJb_pQ

Mr. Retrolust TV Bezels:

https://mega.nz/folder/afh0TLLA#vkiCmBbK5hfc2XwTVC35GA

2. Unizip

3. Go to your Retroarch’s shader folder, and create a directory called “uborder_packs”. (Do not create it in shader_slang, but on its parent folder, “shaders”.)

4. Paste the unziped folder you downloaded, and load the desired preset in Retroarch.

5. Enjoy!

Edited 90s the best I could with GIMP, to remove the light on the lower bezel and make it reflective:

[bitman]

Hylian dropped an ambient light feature (!!).

So I have added a [90s bitman ambientlight] to the presets, along with its border brightened in GIMP. I’ve also re-done the lower bezel edit so it retains its shape.

If you want the border to be darker, like in “bitman 90s”, just go to Shader Parameters in Retroarch and lower “Border to Ambient-Light Weight” to something like 0.25 or 0.30

[bitman]

• Made a [90s bitman ambientlight BRIGHT] variant for the default “Border to Ambient-Light Weight”, which is 0.50.

• The base [90s bitman ambientlight] is set to 0.25 like in the last image.

[bitman]

• Added a third variant, and made it the default [90s bitman ambientlight]. It uses the “Lights off” option. This way the screen really looks turned off when there is black content.

and it lights up just the right amount, giving it a more natural look with the base image

So this is the new default. The previous default has been renamed to BRIGHT, and the other preset to BRIGHTEST. I hope this is not too confusing.

[bitman]

To clear things up:

• [90s bitman ambientlight]

@bitman

• [90s bitman ambientlight BRIGHT]

@bitman

• [90s bitman ambientlight BRIGHTEST]

@bitman

I’m not sure if I should add separate presets for koko-ambi or change the defaults again

[Hyllian]

One advice, choose the one you like the most. Giving support to two is very demanding.

[bitman]

Added new [90s AMBILIGHT], along with another edited border to work better with it:

Screenshots don’t really do it justice. This looks amazingly good when transitioning from black screens!

[bitman]

Since Hylian will drop support for his own version of “ambient-light”, I’ll probably have to remove the presets that use it.

I may use it as a chance to declutter. I have way too many variants of the same 90s preset!

If anyone downloads when I do this, I recommend deleting the entire folder and starting fresh so there aren’t so many items on the list.

On a side note, I’m trying to make a copycat of @kokoko3k’s GBA Night

However, I get a strange rainbow effect, whenever I try to tamper with either the integer scaling, zoom or aspect ratio.

The only way it looks correct is with integer scaling at default size, which is very big

Perhaps you know what causes this, @Hyllian? Happens with “dot” too

[kokoko3k]

Can’t help with that specifically, but you have to consider that you’d need 3x core horizontal resolution to hope to display full mask RGB and avoid rainbows, (one triad per core pixel).

Differently, you’ve to sacrifice it somehow, depending on the shader params; see here, even at 1080p, is not that “steep”:

Koko-aio shader discussions and updates

This is possibly the new/tweaked gba preset instead; previous one was too bloomy, even there adding ghosting (about 2 frames) [Screenshot_20241211_180229] [Screenshot_20241211_181228]

@bitman

Since Hylian will drop support for his own version of “ambient-light”, I’ll probably have to remove the presets that use it.

Why? Koko-ambi is still there with uborder. You just need to change your path.

[bitman]

Thank you for your answer. I think I’ll settle for crt-nobody for the time being

@Hyllian

Why? Koko-ambi is still there with uborder. You just need to change your path.

You mean move them to koko-ambi? I probably will move the base ones (70s 80s); but the only ones that are using the “ambient-light” are 90s variants at the moment. Since I only really need to keep one, and it’s already converted, I might delete the rest (unless someone is still using them over the last preset I made)

[Hyllian]

Uborder-koko-ambi.

It does the same thing as uborder-ambient-light. That’s the reason I’ll drop the last.

[Hyllian]

It’s already available on uborderv0.2.2

[bitman]

Yes, “90s AMBILIGHT” uses uborder-koko-ambi

The gba screenshot for the preset I’m doing is using it as well

[Hyllian]

@bitman

Perhaps you know what causes this, @Hyllian? Happens with “dot” too

As already said, some shaders need a bigger size to work properly.

[bitman]

• Added a new “Handheld” foler, though at the time it will only be for GBA.

https://mega.nz/folder/bLp0kDSQ#4yWB0Y7B3nILCk15XpSvmQ

Updated the preset

[bitman]

• Added a copycat of @kokoko3k’s, [koko-like AMBILIGHT]

I will probaly stop for the time being, as I’m getting config fatigue

[bitman]

Remembered I wanted my arcade presets to use ambilight, so here they are:

[Cabinet AMBILIGHT]

[Cabinet Vertical AMBILIGHT]

I highly recommend deleting your local “generic-arcade” folder. I re-structured it and renamed the files to be more intuitive. To change which preset you want, change it from the corresponding “CORE-ASPECT-ORIENT-XX” slangp file. To load them, use AUTOLOADER.slangp

Remember, this is the link: https://mega.nz/folder/aegwmKBA#a6hCwasJThG-01GqxJb_pQ

Additionally, I have added a more subdued TV ambilight preset

[90S AMBILIGHT SOBER]

Okay, now I can stop in peace

[Boz1978]

Awesome stuff pal! great progress
