@BillHopeItWorks Delete all .xml files pertaining to FB Neo along with the Metadata, Images, Roms, etc. When you go back to import the games make sure you **DO NOT** select "This is a full MAME set." I had this same roadblock with my MAME romset for almost 2 weeks until I finally gutted it and figure out this work around on the Android version. It's worth a shot!
