Four Swords is a special case in that in requires at least two players to start, and from what I've heard, the stages are quite random. Supposedly, the setting of the stage is randomly chosen from a few different one, and then a specific part of that setting is also chosen at random. Mapping it would require playing through the game many, many times to cover all the potential stage settings and dungeon parts.
