That is the usual errors that come with path error. I broke a path to check.

This says no.
I have temporarily uploaded new screen decals. When the shader is updated with a fix I will replace them again.
I’m still thinking about the ADV and doing some testing.
ok, sorry for the bother, it’s the only one that i have encountered with this problem.
i have chosen advanced for all others but they are on vulkan which may mean my gl drivers are not good enough on AMD for advanced set
Hey I am still unable to apply a preset, I got this error in the log.

Sorry for the jumbled mess, and sorry for filling this forum with useless questions, but any help would be appreciated.
Which preset exactly were you trying to load and did you try more than 1?
Edit: I just re-read your post. Weird that the ADV gives you an error and the STD does not.
No need to apologize. 
What are your hardware specs?
Duimon files are supposed to be at Retroarch/shaders/Mega_Bezel_Community
No, just
shaders\Mega_Bezel_Community
The paths are relative. The shaders folder can even be on a separate drive.
But you are correct. The files are in the wrong location.
I have a 3600x and a 2070 Super, with 32 GB RAM
Oh my goodness I hadn’t even realised! Is this a better location?
RetroArch\shaders\Mega_Bezel_Community\Duimion-Mega-Bezel
i tried the advaced gce vectrex set not all but about 4 or 5 and all did the same error
Yes but you can keep the Retroarch-new or whatever you like. It’s just shaders/Mega-Mezel_Community/Duimon... that is important
Actually you could change the Mega_Bezel_Community folder name and/or the Duimon-Mega-Bezel as long as the path depth stays the same and the Community folder is in the root shaders folder.
Well sadly no preset works still
Yeah I’m kind of stumped. You could try setting your RA Video driver to Vulkan. As long as you have the RA “Core>>>Allow Cores to Switch the Video Driver” set to on it makes no difference…
Let’s get another log and you can add you can select the log contents and press the “formatted text” button or add ` a backtick before and after the text to make it legible.

Do you have the Mega Bezel installed still?
You had the Mega Bezel path correct in your last log. Maybe you moved it with my presets?
Ah it did, I messed it up moving this preset!
It works now, thanks so much, and sorry for bothering you!
YAY! Make sure to play around with the CRT shader settings to make it your own. You can save a core, content directory, or a game preset when you like it.
Most of all have fun. And be sure to try a “Night” preset with the lights out in your room.
i guess its the AMD gl drivers, everyone knows they aren’t very good, my guess is it can’t handle the advanced set but the standard ones work, that’ll do for me. Look forward to getting the corrected orientation ones when you’ve done them 
Thanks for all the help and again thanks for the awesome work you’ve done with these
