I guess something like this could do the trick? But I guess it needs further tweaking for database files.
fbneo_libretro.info
display_name = "Arcade (FB Neo)"
authors = "Team FinalBurn Neo"
supported_extensions = "zip|7z"
corename = "FB Neo"
manufacturer = "Various"
categories = "Emulator"
systemname = "Arcade (various)"
systemid = "fb_alpha"
database = "FB Alpha - Arcade Games"
database_match_archive_member = "true"
license = "Non-commercial"
permissions = ""
display_version = "v0.2.97.44"
supports_no_game = "false"
notes = "(!) The BIOS files must be inside the ROM directory.|(!) You need a copy of neocdz.zip and neogeo.zip in your libretro system directory for neocd"
