Koko-aio shader discussions and updates

Batocera use a slightly older version.

As per the Duimon bezels, look at the first post, there is a linked repo with all of them.

Your shaders work beautifully everywhere. I noticed that the version on Batocera adapts to vertical or 4:3 games automatically, while on Windows I have to do an additional manual step. Grazie !

Weird, shaders are shaders, they do/should not depend on operating system.

What step?

I don’t know what to tell you, on Batocera the formats adapt to the vertical or horizontal game, on Windows I select the shaders format in the shaders setting, considering that I select the format in both cases with “Core Provider”

Hi kokoko3k , I have a problem with my favorite preset tv_pal_my_old. The RF option causes screen overlay flickering or a black screen. It seems to me that the problem also occurs in other prests that use RF noise. I use windows 11 and gl core display driver in retroarch. Would you mind taking a look at this?

I think it depends on the underlying retroarch configuration.

For vertical/horizontal games rotation guessing, koko-aio needs:

settings->core->allow rotation:on

Also, if you want ambient lights and borders to be visible, aspect needs to be set to “full”, not "core provided’.

Yeah, I remember to have fixed this bug in the past, before the latest release.

Can you try to update retroarch shaders via online updater and check again?

I constantly update shaders and retroarch

PS Video Driver GLCORE

I think you missed the reply.

I have the latest version. I changed the display driver to vulkan and it’s the same. I am currently testing the problem on the genesis plus gx core - sega mega drive, but it is the same on others. If the problem does not occur immediately, simply turn on a given preset or turn on RF noise several times in a row. Borders will flash or the screen will go black.

Works fine here with retroarch shipped shaders. If you’re 100% sure you updated shaders too, it has to be something else on your side, but i cannot imagine what.

This is what Sunset Riders looks like (the Sega Mega Drive version). Saved the tv_pal_my_old preset without any modifications for the entire core, then restarted the game. Retroarch latest version nightly. I’m using a 120 hz monitor under Retroarch, with all screen settings set to default except video output, and screen aspect ratio set to full. It would be good if someone else could check. It may be ok on Linux, but there is a problem on Windows 11.

The only solution is to turn off RF noise - only this option causes the problem.

edit: Adventures of Batman and Robin (pal version) here. Black screen at first. After a few moments, when the game changes screens (intro, menu, etc.), flickering appears. It’s hard to capture it on a screenshot.

Retroarch updated or not is not important, shaders updated are.

Please, post the content of the slangp preset you are using, the one you saved as default,under [retroarch root]/config/corename/something.slangp

Also, what’s your gpu?

Last thing you ,0may want to try is the upstream/in development version on github repo linked in the opening post.

This is Mame Core Option

I deleted the koko-aio folder several times and downloaded the latest version via retroarch shader updater. I’m using rtx 370ti and have the latest drivers available on the nvidia website. In the Genesis Plus GX.slangp file I have the following: #reference “:/shaders/shaders_slang/bezel/koko-aio/Presets-4.1/tv-PAL-my-old.slangp” I’ll check the github versions soon.

edit: First, I downloaded via github: koko-aio-slang-NG-1.9-Hotfix-2-slim I tested Sunset Riders and Adventures of Batman… no problems with RF noise. Then koko-aio-slang-NG-1.9.13 and here the problem occurs, the same as I described.

WAIT !

Not work :frowning:

What’s your retroarch version? What’s the core and have you updated cores? Also please try with retroarch aspect set to full.

Retroarch 1.17.0 Mame Core is 0.197 but I can’t update the Mame core as I would have problems with the roms. I update all the cores, shaders and whatnot but not the mame core

It appears like the core is telling the shader to use a wrong aspect ratio, that’s why i suggested you to set aspect full and not core provided.

it’s under video/scaling.
