Koko-aio shader discussions and updates

yes, it could be that. Also, could you check the current version of mame (0.251)?

definitely not tated, you can see by phosphors, will check mame 0.251

Have you already tried to switch from/to vulkan?

Yeah, also use Vulkan when I can.

mame 0.251, working fine in forced or even auto mode: image

Odd…on amd vulkan? Using the latest repo code?

Hello @kokoko3k, and hello everyone. I think I found the ultimate configuration by going through the “Monitor-ScreenLevel-HmaskWide-Corelevel-Slotmask” preset. Here are some images that you can see through links taken from the arcade version of “Marvel Super Heroes”. I think that just a little more brightness is missing, if you have any advice or shortcuts for me please let me know, as well as your feedback. Compared to the reference preset, I activated the FXAA and the CBVS, the latter had the strength modification at the value of 0.30. The rest is unchanged from the author’s settings.

Premise: I’m looking for smoothing the image with a retro style. Unfortunately the FXAA, although very good and light, does not guarantee the results of a ScaleFX, which on the contrary is extremely expensive. Playing with the blurs I managed to get a style very close to what I’m looking for, except for some small details. The koko-aio Shaders allow you to have great results with minimal effort, and this is a miracle for those who currently do not have very powerful machines, for those who want to run them on lighter hardware, and in any case as a fantastic alternative to complement the others. Thanks always to Kokoko3k for his invaluable work.

It seems already bright to me, trying to squeeze more is going to ruin the mask, and since you’re using an *oled screen with your smartphone, increasing its brightness is the way to go (blacks stay black and power consumption will not be affected).

Better late than never,
other than the dumb deconvergence obtained by just offsetting the whole texture channels around, now you can offset single phosphors too, this is how it happen in the real thing:

Main difference over the previous method is that the ideal scanlines gap will be now filled by the phosphors you stagger, and indeed the new settings live in the scanlines section, because have no meaning outside of it, here you can see a cloesup of having staggered the red phosphor down alot:

Keep in mind that for more accurate result, you should use the old deconvergence setting so that it matches vertically the phosphors one, it is not mandatory tho.

Hi, some advice. In my case, do you advise me to stay with the old active setting (which I find active by default in your preset with the relative parameters) or try to use this new method? Always grateful for your work.

Thanks. I set strenght at .30 (up from .25 on my old settings) with rest as above. Looks good - Altered Beast Arcade shows the effect really nicley with the White Wolf (power up).

Play with the offset and see if you like it, i don’t think it would make difference on tiny screens anyway :slight_smile:

Hey bud, sorry for my vast ignorance but, Do you have any recommended preset from yours (if possible with crt Monitor overlay included) to use for DOS games ? Couldn’t find many suggestions around.

Would appreciate any help.

Always love to use your reflections feature for Sega Genesis. Thanks a lot for making all of this possible!

No luck, I was an Amiga fanboy, and I hated everything around the world of mSdOs back in the day, the look of it was colorful on VGA, but was blocky as I remember with no visible scanlines, right?

You can give that some life by using the preset from the dev repo which uses the new ambient light wide modes, if you can stand a 1084S from Commodore :slight_smile:

It should look similar to this (can’t take exact picture from preset right now, preset has changed a bit meantime), taken from some posts ago:

Monitor-Ambilight-immersive.slangp
under /presets-ng/Safe-to-use/ directory.

where could i get those overlays please?

It is just one overlay, the color changes following the content.

it is the default koko aio overlay, shipped with it, you just need to load the preset I pointed you, but you’ve to download the development version of koko-aio, see first post for the link.

@estefan3112, have you exploited that led internalness setting in your overlay repo?

Just went there and they are fantastic!
