 To make one, simply create a text file with the same filename as your intended game name (this is what will appear in your game list. It could be anything, really).

 +If creating the playlist file with Windows, be aware of the [[https://wiki.batocera.org/github-desktop#note_for_windows_users|line ending limitations]]. For most systems, this does not matter, but some will only read playlist files if they use Linux-style line terminators.

 +Batocera will automatically hide duplicated entries showing in the gamelist when using playlists to define which discs are a part of a single game. However, this will only work when the playlists are referencing just the filenames; relative pathing will override this behaviour and show all discs. To put it simply:
 +
 +  * ''filename.cue'' -> hide this disc
 +  * ''./filename.cue'' -> don't hide this disc
