The content of Four Swords is an sfc replica plus four Swords, and four Swords can only be played by many people online. So when you play Four Swords, you only play the replica version. Cap shrinking is specially developed for gba, and is generally called the strongest gba game in history. The screen is more refined and easy to use (sfc reproduces that, but it is not easy to use). The first contact must be to choose to shrink the cap. If you feel good, try four more swords.
