Hello, I have a theme from an old version of Batocera that I would like to use in Batocera 43, however, although everything else works fine, it does not work on the Main Menu, I wanted it to do the same as several other themes, editing the background color, font color, font type, etc., would it be possible to create an xml just for this and place it in the root folder or place it in some folder within the theme folder and use include in the main xml?
