Many thanks dink! Unfortunately, it looks like this batch file removes many non-mature games as well, E.G. the Goldenaxe and Metal Slug games as well as others.
Here is the list of games removed with DELETER:

Prior to posting this thread I googled for ways to remove mature ROMs from FBA and found some helpful results, but they were all regarding MAME and not FBA, like this post, for example:
https://retropie.org.uk/forum/topic/18692/removing-hiding-adult-gamesI assumed the ROM file names differ from MAME to FBA. Also, I assumed that FBA has games which are not emulated by MAME.
However, if, as I now suspect, both of these assumptions were incorrect, then I can use the removal methods I found for MAME. For example, I found the file mature.ini here:
https://www.progettosnaps.net/catver/So I just added all the ROM files in it to a batch file with a "del" command and the resulting files that were removed seem to be actually all mature games. Here is the list of games removed with mature.ini del.bat:

But now my question is, were both of my previous assumptions wrong? Are the MAME and FBA file names all identical?
