    I'm trying to to trim a few romsets, mainly zx80 and commodore amiga roms, following this guide: https://www.reddit.com/r/RetroPie/comments/5njtvs/guide_how_to_trim_your_romset_of_duplicate_roms/

    A part of the guide states this:
    Click on "1G1R Mode" under "Region / Language Mode" down at the bottom. Note that if you have the wrong DatFile XML this option will be greyed out.

    I made sure that I got the correct parent-clone dat file from https://datomatic.no-intro.org/ but it still won't let me trim it. Is there something that can be done about this? as there are several old computer or game console romsets that I can't trim even though I have the right dat files.
