M3 simply card won't play your files

Hi there
I Have an M3 Simply card which won't play your files, it says they are all invalive file formats.
Is there a download I can put on the card to allow the system to read the games?
you may have to spell out instructions in steps as i am 30 and new to computers!!!! lol

You need to extract the roms.https://www.romulation.org/forum/index.php?topic=3880.0
