So what you want can be achieved by:
And for FBNEO turn off vertical mode.
One last note is that you need to set the Rotate CRT Tube parameter to 1
In the presets/variations folder there is a preset already set up like this named FBNEO-Vertical__STD.slangp
Don’t forget Flip Core Image Vertical and Horizontal have to be set to 1 as well.
On my end I have to set both to 1 because if I don’t than it’s upside down. Found that you only have to do it on select games, ie it had to be done for Dig Dug but not 1942.
only with the configurations in retroarch, when launching the game it looks like this, before applying shader
Load the Shader Preset, apply the correct settings to rotate the game then Save the preset as a game preset.
If you keep all of your vertical games in the same folder, you can save a Directory preset instead.
I see that “Up” is on the left and in my case “Up” is on the right. I have not been able to try another game
Yeah, I tried Donkey Kong and it was the same way as Dig Dug. I did do the 1942 game and it was the same way as you had it. I think it is a game by game situation.
I found this and it will help me to generate an exclusive folder for that type of games

Mega Bezel is updated to V 1.0.003 2022-07-28 Rev 1
Changes:
HERE ARE THE LINKS!
Extra Examples Package (Examples haven’t been updated in a while, but should get updated soon)
INSTALLATION INSTRUCTIONS
If you have a previous Mega Bezel install:
Inside the .zip is a bezel folder, copy the bezel folder into your Retroarch/shaders/shaders_slang folder
Retroarch/shaders/shaders_slang/bezel/Mega_Bezel
Retroarch/shaders/Mega_Bezel_Community_Collections/HSM_Mega_Bezel_Examples
Set video driver to Vulcan
Open the Settings Menu and Set:
For FB Neo
Load a preset in the shaders menu, Mega Bezel shader presets are found in:
shaders/shaders_slang/bezel/Mega_Bezel/PresetsWhen you save a preset make sure you have the Simple Presets feature set to ON
Tube-Effects__Night__ADV.slangp preset showing fixed stuff including masking and reflection
Gel on top of Tube Diffuse
STD Preset
Old SMOOTH-ADV
New SMOOTH-ADV
This has now been merged to the libretro repo so you can also get it with Update Slang Shaders
Yeah it’s looking good. I’ll make the necessary changes and include them among the rest of my preset updates when they are ready.
@HyperspaceMadness Thanks for the game screen radius as well. 
Very nice work!
Hello! Wonderful! Is there an option to change the aspect ratio without altering the tube structure? For example, changing the aspect to 3:2 (GBA) within a 4:3 tube, consequently giving it some black borders, I want that because it would be more accessible to set up GBA Player Border without messing with the tube structure.
So my idea is:
Create an option to change the aspect ratio of the game within the tube without altering the structure (even if it gives black borders).
Add the colored gel border.
Add empty space to correct position of the border image.
Hmm, so it’s sort of possible to do this already, basically you increase the tube empty thickness until the tube is as tall as you want it, then increase the tube extra thickness scale x which will widen it.
But I’ll think on this to see if there’s a better solution, perhaps a parameter to enforce a specific aspect ratio on the tube
Yeah, but when I alter the scale x the tube structure changes a bit, it gets thinner on the sides and other changes in the corners of the tube.
Could you post some screenshots to show how it’s looking thinner and weird reflection in the corners?
Hi! Here:
No matter what I try, I can’t make the tube look the same. I know I can do that with some work and maybe some calculations.
What is the recommended image size of the Tube Colored Gel Image?
If you make it 2880x2160 then it will be sharp on any screen up to 4k.
Hello everyone, very much enjoying this bezel pack. I especially appreciate the automatic scaling and aspect ratio, all of the systems look great. There’s one small issue I’m having though, specifically with two systems only so far, the TurboGrafx-16, and the Sega Dreamcast.
Where is my other systems/cores fill up a good portion of my laptop screen, which is a 1440p display with a 16:10 aspect ratio, leaving only a small amount of extra space outside of the onscreen bezel edges, these two systems only have a very small display comparatively in the center of my screen and appears that there is much more extra room they could be using. Please see the picture.
Is there any way to make them larger, taking up most of my screen like the other systems without ruining anything? The only settings I have changed in the shader relate to the shadow mask and other things regarding the CRT features like brightness, etc., nothing relating to the bezel.
