Multiple playlists can be generated based on the Base ROM Path
setting.
In order to generate multiple playlists simultaneously, all of your ROMs need to be organized as subfolders of a “base ROM” folder. The names of their subfolders should be the names you want for each playlist.
For example, on this screenshot, I could generate playlists for these 16 systems simultaneously (although there would be some extra steps for the PlayStation). In order to generate these playlists I would set the Base ROM Path
to f:\Lakka Buildout\roms
