"No devices found": Your roms folder path is incorrect. Check the mame.ini configuration file to ensure the rompath variable points to your folder.
Black Screen on Launch: Press Tab > Video Options. Sometimes MAME defaults to a resolution your monitor doesn't support.

Version Matching: A critical hurdle is that ROM sets must match the specific version of the MAME emulator being used; older sets often have "spotty compatibility" with newer MAME releases. User Experience: "The Filter Problem"
