I would go get an old Ultracade or Arcade Legends. Quality parts, not 2500 games, but the classics and well laid out menu. Having done many of these by hand I find that while the number of games is held out as the success metric, you really won’t play most, and they clutter the ones you do want to play. Most standard renditions of newer built multicades use a Hyperspin front end that in heavy use seems to crash more often than not.
