In this edition of Four Swords, is it different than the GBA version? Or is it the same?
Kai said the main difference in that the DS version (anniversary edition) is playable in single-player. Other differences, most of which are mentioned on the Wiki page:
- Not paired with a game (A Link to the Past)
- Multiplayer done through DS Wireless Communications instead of link cable
- Two new stages: the Realm of Memories and the Hero's Trial, each with three doors. Each door in the Realm of Memories is based on a previous Zelda game and has more challenging puzzles compared to the other levels. The Hero's Trial is considerably more difficult than the other stages, functioning as a "hard mode." Completing these rewards the Master Sword and Hurricane Spin, respectively, which could previously only be unlocked with A Link to the Past.
- Some sound effects and tracks were improved
