I've got the arcade category setup in BigBox, and it is showing all games in the folder. Hundreds or thousands of games, I imported the full MAME set (with filters to get rid of casino, etc, all the default checked filters). Still, way too many games to be useful. I made a My Favorites playlist of just the MAME games I'm interested in. How can I get that playlist to be the only games that show up in BigBox under the "Arcade" platform?
