Hey, these all look so nice but I am so confused on where to place the “koko-aio-slang-main” and “koko-aio_packs” folders. It looks like some of these presets are calling ofr resources that isn’t where it is looking, so it is throwing the failure to load error. Would you please be kind enough, @kokoko3k , to tell me where each folder belongs and the correct structure (like in the “\path\to\retroarch\shaders\more\shaders” format? Thank you and I am sorry you need to hold my hand with this. I swear, I am not always this competent!
Excellent work, I really like the work you have done and what a good update. Now it’s time to update the Duimon presets https://github.com/kokoko3k/koko-aio-slang-presets-and-overlays/tree/main/Duimon

The shader update to NG is available via official reteoarch update, so just do the normal update process and select a preset from bezel/koko-aio.
Where koko-aio_packs come from btw?
edit
Ah, gotcha, those from @starman99x need to be updated by him to point to new folder structure, so broken atm.
Just noticed that retroarch update process does not clean the folder from old files.
As a result, after the update, bezel/koko-aio is a bit messy, because contains a mix of 4.1 and ng versions. Both still works, but new stuff (and old stuff ported to new code) live in subfolders now, all the extra stuff is useless and the whole folder should look like this:
To cleanup, delete bezel/koko-aio folder and run the update process again, maybe there is another way @hunterk?

hello I had a question I wanted to play The Ninja Warriors but the screen remains only in 4:3 is it possible to create 3 screens with your work?

no, that’s the best way to handle it, unfortunately.

If you see it distorted, you can use options to force a 4*3/3=12:3 aspect ratio, if you see right proportions, you can use options to zoom out (global zoom option).
Let me know how it goes!

Perfect you managed to do it.
I was about to suggest you to disable bezel, curvature and scanlines, but it seems you preceded me 
For reference, that worked for me on 1080p:
- Aspect ratio: Numerator:12 Denominator:3
- bezel disabled
- curvature disabled
- Global shift/zoom: zoom = 0.44
- Scanlines: 0

thank you for your advice it will be useful to me if I come across a game like the ninja warrior has 3 screens

Trying the “Slot Mask - Overmask” preset with FXAA activated: what do you think? However, I believe that very bright screens are needed for “Overmask”, or am I wrong?
PS these games are the Neo Geo CD version

Overmask works by pushing the source color and highering the mask contrast.
That means picture brightness can be lower because you cant push the brightest colors, so yes, overmask may still need a brighter display and higher resolutions (to mitigate moire), but still, are very attractive to me somehow.

All my koko-aio packs should be working with the latest koko-aio now. But I didn’t try the new NG presets yet, so no new stuff yet. And I hope @kokoko3k won’t make the 4.1 presets obsolete in future releases, that would really suck.

I’m sorry @kokoko3k I need my hand to be held for this process. I can’t figure out where to put these folders. They keep failing when I try to apply them. In my mind, this is because it is not in the correct location. I placed koko-aio-packs and koko-aio-slang-main inside “retroarch\shaders\slang”. I figured these are different from koko-aio, found in the bezel folder.
EDIT: @Starman99x Hey man, thanks for commenting, I downloaded your update but it seems that no matter where I place the koko-aio_packs folder, it errors out on me. I fixed the issue with koko-aio-slang-main by replacing the koko-aio folder found in “shaders\bezel”. I tried placing the Duimon, Starman and Exodus folders in all of the differen the preset folders inside koko-aio but still they fail to load.
No plans to do that, thanks for the update!

Thank you so very much @bactino 
Edit: One more question, do I place the folder koko-aio_packs in the same bezel directory?
Hey bud, yes they do work correctly now, thank you, you are awesome! Though I went back to @Starman99x github page and read that the “koko-aio_packs” folder needs to be placed directly into the retroarch\shader folder, so I did that and left a copy of it in my bezel folder as well…just in case. It is getting late and I am sleepy, so I will do more thorough testing tomorrow morning (it’s after 1am here).
