Sorry to continue this old thread, but I’m not the savvy with this.
I’ve been using this pack for a while, but recently I updated the assets and shaders with retroarch and it messed it up. It now has this weird white glow around the letters and everything, I don’t know if I can fix this in the shader’s parameters or I have to do something about the updated assets.
Hi, “SirCharlesV”. 
You might be able to fix this problem by re-downloading a previous version of the emulator that was released around the same time as this shader, 6-11-2023.
Version 1.15 fits the bill: windows - buildbot.libretro.com > stable > 1.15.0 > windows (you can navigate to another version).
Alternatively, see if replacing the current shader folder with v1.15’s shader folder resolves the issue.
The folder is usually here, \RetroArch-Win64\shaders\shaders_slang
My suggestion is not to update the emulator unless there is a new feature or shader that you want to try out – cores are OK to update, though. I hope this is useful.
That fixed it. Thanks!

Yep, lesson learned!
Best thing is to revert to the version of Mega Bezel Reflection Shader you were using before you updated, or just stick with the version that @Zombeaver used when designing the Preset Pack. Next time backup before updating.
love these shaders!
The triple screen works perfectly 
However, using the double screen, it seems
like it’s too stretched. In fact, it seems very much like the triple screen.
Is anyone able to assist?

the strange thing is, the double screen (exactly the same shader presets) work fine for arescue.zip (mame). Seems like it’s a problem when turning it on for cyberbal.zip
What core does cyberbal.zip use? (Since you don’t mention mame after it.)
sorry, mame (current), so the 0.277 core on retroarch.
I am thinking there is a file somewhere in the pack which references the game title (no-intro) and instructs which Zomb’s Mega Bezel screen (single, double or triple) to load the rom in, maybe?
There is no such thing as a (no-intro) MAME romset. 
He probably has the aspect ratio hard defined. You could try setting it to PAR in the shader parameters, and save a game preset if it looks correct.
