ALttP on the GBA is just about what you would expect: same experience for the most part but with lesser music, less buttons, and a smaller screen. Voice samples were also put on Link in this edition (to the displeasure of many), and some new content related to Four Swords as a reward.

Speaking of Four Swords, this is Zelda's first foray into multiplayer. It's actually a great romp with friends with an interesting combination of co-op and fighting each other over loot, if you have three link cables and four GBAs to facilitate it. Just remember to hold off until you've obtained the Master Sword in ALttP.

Tired of the pink haired Link? It was previously done on SNES, but it hasn't been done on GBA so here it is. The Link on the save menu will still have pink hair, though. Once in ALTTP, he will be dark blonde. This will affect his rabbit color too. Aghanim's palette has also been updated so it matches his artwork. It will also change the King's palette seen in the intro.
