MAME / Final Burn Neo bezels

[CapSwey]

I'm using Duimont shaders in RetroArch for my systems and plan to keep on using them. But for some systems, like Final Burn Neo, I would like to use bezels as well. Since there are black pillar borders around the monitor screen. There are no MAME or Final Burn Neo bezels present in the RetroArch/overlays/GameBezels directory at the moment. So I would like to combine the Duimont shaders with an extra bezel overlay for FBNeo.

For standalone MAME I'm using the amazing 'Lights Out!' bezels by Mr. RetroLust (https://forums.launchbox-app.com/files/file/2225-mr-retrolusts-mame-4k-lights-out-realistic-bezels-artwork/?tab=reviews&sort=newest#review-3059). I want to keep those intact, so I'm a bit afraid when importing/updating bezels with LB's import function, and NOT selecting "keep existing metadata", that Mr. RetroLust bezels will get overwitten.

How do I find the proper MAME and/or Final Burn Neo bezels, so I can place them in, for example RetroArch/overlays/GameBezels/MAME or RetroArch/overlays/GameBezels/FinalBurnNeo folder, and configure them manually in RetroArch?

Or is there maybe another/better way to approach this?

Cheers for all the help in advance!
