Duimon koko-aio Presets

Duimon · 4 April 2025 01:47

Thank you. I opened the file and curated what I hope is all the two character shortcuts.

koko_shortcuts.txt

Color correction ----------------------------- (co)
NTSC color artifacting ----------------------- (nt)
YIQ/YUV bandwidth limited chroma bleeding. --- (cv)
Input Blur / light glowing ------------------- (gl)
Pixel Grid ----------------------------------- (ph)
Halo ----------------------------------------- (ha)
Bloom ---------------------------------------- (bl)
Curvature ------------------------------------ (cu)
Bezel related -------------------------------- (be)
Background Image ----------------------------- (ba)
Vignette and spot ---------------------------- (vi)
Tilt ----------------------------------------- (ti)

In case anyone else is interested in a list.

FYI… just in case anyone is unfamiliar. Once in the shader parameters dialog, you can press the “S” key on the keyboard (Search) and search for one of these “shortcuts”. ( i.e. search for (be to jump to the bezel section.) The first three characters should suffice.

Hey there, I think this preset performs a bit better than the one used now as a base for your arcade presets; it uses the dehive function not yet released tho.

See, maybe you want to add it to the commented options if not makong it the new default.

Sounds good. I am working on an update and will wait until it’s available to make the final changes.

I still have a lot of testing to do anyway.

@kokoko3k

Turns out I am using the 1.9.63-Hotfix1 and it has that preset. Even if it’s not exactly the same as the development version, it has the same name.

I can just enable that base preset in the arcade systems.

I’m going to test it right now.

kokoko3k · 5 April 2025 10:10

Yeah, there is; I think just not as good as the one as of today.

A thing I did not considered is how the preset behaves at 1080p when is zoomed out due to more bezel visible… I’ll need to check that.

-edit-

Right, at least till 640px height (content), it wins the moire roulette:

Which preset would you suggest for high res arcade systems like Naomi? without interlacing?

kokoko3k · 6 April 2025 09:49

Maybe one of tv* ones? They do not draw scanline gaps (they are not visible on interlaced screens).

You can then choose if and how much flickering effect you want; that was indeed visible instead, but is a matter of taste.

In the latest dev code, the flickering is also automagically lowered when the shader detects 30fps content too, so is more consistent now.

Starman99x · 6 April 2025 22:55

I did more research and tests and settled with:

Monitor-Screen_Hmask-Aperturegrille.slangp

This preset works well with interlacing off if one is trying to mimic a progressive signal via a clean RGB monitor like the ones found on real Naomi candy cabs.

VGA presets are relevant in this case aswell.

But I think I’ll use the aperture grill hmask one with all hi-res systems from now on.

Starman99x · 6 April 2025 23:01

While we are on the subject, I want to suggest trying the PSP preset with 3DS and DS, I felt it was more suited for higher res or multi-screen handhelds.

Starman99x · 8 April 2025 05:48

@Duimon It seems the recent Dosbox-pure versions introduced the dreaded glcore flip issue, it’s especially bad with DOSBox [Monitor] presets and IBM_5150.

Since they can’t use the same flip fix as the [Bezel] presets.

Duimon · 8 April 2025 13:30

Interesting. They must have developed hardware rendering.

No worries, they can still use the wildcards, they will just need some tweaks. I’ll probably use the $PRESET$ wildcard to take care of it.

Duimon-aio-small

* * * The repo and release are updated to v0.6.2.0. * * *

Changes:

Rerendered all custom bezels so that they don’t have any default shading. (Legacy rotated images are still present, just in case. )
Changed all paramters to accommodate the new bezel methods.
Updated base preset paths and added a method to use unlisted/alternate base presets. (This effects nearly 100% of the presets in some way.)
Added tilted cabinet versions of MAME, FB-Neo, and Arcade presets.
Added NDS Book and Hybrid presets.
Added missing variants of Camputers Lynx presets.
Added Sampo 9519, Sony TH20-B8, TV5 (RCA GJR641PR), and TV6 (Ambassador_26) presets. (In the “TV” presets folder.)
Added auto flip wildcard params for LRPS2. (LRPS2 (alpha) is still present to accommodate users who have yet to update.)
Added auto flip wildcard params for DOSBox-pure.
Renamed misspelled graphics that broke homebrew Vectrex presets.

The link to the current release and installation instructions are in the first post.

I fully expect this to have bugs. Please post here when you find them and we can work together to make everything right.

Software renderer + glcore = flipped textures (melon ds ds)

This was not an issue in the previous version. It’s not a big deal but I’ll report unexpected behavior as I go.

Duimon · 25 April 2025 00:13

This has always been an issue with cores that give a choice between hardware and software rendering.

There is no wildcard to detect software rendering, so if you use it, and glcore, the auto flip wildcard settings will detect glcore and flip the textures. This is a feature limitation, not a bug.

I could create a preset that doesn’t reference the wildcard stuff, and name it “software_glcore” or something, but I think it would be easier to just have the user flip it and save the preset.

I am pretty sure I posted about this while I was creating the book preset.

Thanks for chiming in with the issue.

Starman99x · 27 April 2025 02:41

Not sure if the problem is on my side, but the book preset works flipped upside-down if used with your recommended core option [RotatedRight]:

I was able to solve this by using RotatedLeft + BG_IMAGE_ROTATION = "-1.000000"

Also I would like to request a HybridBottom preset please, there’s no way to get bottom screen focused games to look right with the HybridTop preset alone:

I tried many modes and options, the small screen area cutout needs to be on top for this mode to look right.

Like this for example:

Duimon · 27 April 2025 15:15

This is related to the glcore flipping.

When you switch to software mode it uses the driver that is currently selected. So, if you start with Vulkan everything works as expected. If you start with glcore things get wonky.

As I said before, there is no elegant way to take care of this with wildcards.

I’m glad you found the right settings.

I see no reason to not do one. I’ll put it on the future update list.

No ETA, my koko-aio update was all that was standing in the way of doing a few new graphics, so I will be concentrating on that in the near future.

Starman99x · 27 April 2025 15:51

I’m actually using D11 with this one, I also turned off “Allow cores to switch the video driver”. The D11 has no flipping issue as far as I know, it works just like Vulkan.

Duimon · 27 April 2025 18:34

I checked, and you are correct. Something must have changed since I created the preset. I’ll fix it in a future update.

That being said…

It seems you are actually trying to break my presets by using unusual settings.

I cannot and won’t try to accommodate these scenarios. In the future, please try it on Vulkan before you report an issue.

Thanks for the report.

Starman99x · 28 April 2025 02:18

I’m not trying to break your presets intentionally, I got koko-aio set-up on an older laptop with no Vulkan support. Only glcore and D11 (both with their own shortcomings). The other option “Allow cores to switch the video driver” was off just in case the cores were kicking me back from D11 to glcore (a good safety measure for your presets).

Duimon · 28 April 2025 14:35

Fair enough.

Thanks again. Feedback has always been essential to my projects.
