How can I fix these bezels/overlays use my own?

I realize RetroBat uses decorations and here is my test so far with notes.
I have my own .cfg and .png but I can't even use it inside retroarch? How can I add my own bezel/over files and force Retrobat to use it. I tried placing .cfg/png (retropie) this was straight forward. Just need some guidance or simply add proper bezel in retrobat please for these systems.

Computer MSX2 roms/msx2 - missing decoration/bezel
Handheld Gameboy Advance roms/gba - no decoration/bezel
Handheld Wonderswan roms/wonderswan - no decoration/bezel
Handheld Wonderswan Color roms/wonderswancolor - no decoration/bezel
Console Coleco Vision roms/coleco - no decoration/bezel
Console Family Computer/Famicom roms/famicom - no decoration/bezel
Console Sega Genesis/Megadrive roms/megadrive - wrong decoration/bezel need genesis
Console Nintendo Entertainment System roms/nes - wrong decoration/bezel
Console Sega Genesis 32x roms/sega32x - wrong decoration/bezel
Console Sega SG-1000 roms/sg-1000 - no decoration/bezel
Console Sega CD/Mega CD roms/megacd - wrong decoration/bezel

No one want s to explain how we can change it ourselves?

Consider this resolved and I will be using my own bezels - it will all be fixed . Reach out to me if you want bezel pack I'm 100% using from pi days.

Hello,

Bezels in RetroBat use along with the png a json config file with info extension. By editing it you can set the dimension of the overlay and the X/Y proportion of the screen.

You can sort your bezels by systems and by games by following this structure:

decoration\<name of your bezel set>\system\<system name>.png for systems sorted bezels

or

decoration\<name of your bezel set>\games\<system name>\<game name>.png

along with their *.info file.

Is there any way for the arcade emulator to recognize if the game is vertical or horizontal to use the correct bezel? On the regular Mame it works but not in retrobat.(at least for me)

Thanks

We found that for most arcade games and emulators setting Aspect Ratio as Core Provided was the right choice.

The problem is not the ratio. Games look correct. The issue is with the bezels overlay. For example in name doesn't adjust to vertical games(like normal name does). Or for example in gameboy, the game is covered by the bezels
