Omg, Four Swords Adventures was so much fun!! <3 I really wanna play it again as well, I've been tempted to buy another GBA SP just so I can go back with my siblings. :'D
One of the fondest memories of mine was, after we finished the gane, we'd go back to play around in some of the levels, like in town, or in a dungeon we liked exploring. PLUS getting into 'sword-fights' to see who the better Link was was just hilarious! xD Man, I miss it so much.. :')
