Could you elaborate a little on the two points? I’m slightly confused about what you’re saying exactly.
Sure thing, it’s more of an under the hood thing.
I’m trying to set up the scaling include file that everything uses so it can eventually be integrated into the existing shaders in the repository and people won’t have to adjust their existing presets which use these shaders

It’s best added instead one of the early passes which alter colors. Since it changes colors also it should be a decent replacement for one of those:
color-profiles.glsl
or
d65-d50.glsl
It’s easy doable from the menu and then the preset can be saved. Since it has many parameters and these are already too plenty in the shaders, it will not be included in the official version. 
With crt-guest-sm similar can be done with ease, since it already includes an aditional color pass which can be replaced.

Latest Mega Bezel Reflection shader update is up!
Changes:
- Added Positioning offset for screen and the bezel
4 Likes
Thanks for the update! The new options are very welcomed.
I’d like to point out some issues with the vertical orientation of the shader:
-
The right corner (and the bottom left) are a bit misaligned, as you can see from the bright line of the bezel.
-
The reflection goes above that line horizontally and below vertically.
-
The bezel is big enough horizontally but too thin vertically, making it look a bit unbalanced.
Not sure if these are easy to fix but that’s the only issue left with the shader IMO.

Yeah, this is an easy fix for the misalignment and the reflection match. This is why the automatic bezel generation would be helpful
So you feel the default bezel seems like it would look better with an even amount of space on top and sides?
Thanks for the feedback

GBA games look great on this shader. A version of GB/GBC would be neat as well. Is there a way to adjust one of the current version to match that system’s aspect ratio?
3 Likes
Why did you have to run image-adjustment after afterglow? Just curious.
Hi @Arviel, yes you can adjust the screen scale aspect ratio setting to what you like, the default is 1.33 for the 4/3 screen. You could also adjust the bezel x scale offset to squish the 3/4 aspect of the original bezel image to a 1/1 aspect but this is likely to look bad. For best results you probably want a new bezel image where the screen is already 1-1.
I can make this and provide a preset for it, but I’m a little concerned about how many images and how big it will end up being in the repo when it eventually goes there, as well as flooding it with too many presets.
@hunterk, do you have any suggestions on what’s appropriate for going into the repo eventually?

In my test, the shader loses the light trail effect.
I took this picture to show that the effect has been maintained as it does not appear in the screenshot.
Technically, I can’t explain why. Maybe @guest.r or @hunterk.

Would someone give us shader noobs some tips on installing this and its use? I would love to try this out.
We just want to keep things as small as possible. In the case of the console-borders, there are a bunch of obscure variations that aren’t in the repo to save space and are just distributed in a bundle on the forum, so that’s an option here, too. That is, put the most general-purpose variant or two into the repo and let people who need the others download them separately.

This is such a great looking shader but in the recent versions there is an issue with it when being used with the Stella core, it’s auto adjusting it to vertical orientation.
This happens on various occasions.
It’s best to force it’s aspect ratio option to “horizontal” and save an “auto” preset for MAME, either way only MAME has vertical games without any graphics to fill the left/right areas AFAIK.
The aspect ratio option is in the shader and it’s “auto” by default.

Thanks for letting me know
It looks like the atari 2600 output resolution is 160x192. It’s guessing that it should use a vertical aspect ratio because the ratio of horizontal resolution divided by vertical resolution is 0.83 and is less than 1.
You can always tell it which aspect ratio to use explicitly, but if it’s often choosing the wrong aspect ratio it’s defeating the purpose somewhat. I hope to figure out a better guess so it’s more accurate.
Anyone have any other examples of other cores/systems which have a horizontal aspect ratio display but who’s vertical resolution is higher than its horizontal resolution or games & systems where its choosing the wrong resolution? This could help me see how I could alter its guess to be more accurate.

Yeah I figured it had something to do with the 2600s weird resolution messing with the auto vertical stuff that you added, it was working great before you added that feature in. From my testing with other systems it was fine but I was only doing the mainstream stuff like NES, SNES, Genesis, PS1, Saturn and TG16, nothing exotic.

Thanks for the info @lordmonkus. I added the automatic option for Mame so it can change the aspect automatically for vertical games because trying to handle it manually forces you to choose and save a new setting for every vertical game you encounter, which I would love to avoid.
If the automatic aspect guess stays as it is, then you’ll want to make a copy of the preset and set scl_aspect_ratio_mode = 1 for the Stella core, this will set it to horizontal.

Thanks, that did the trick, just took me a minute to figure out where that setting was.
