This is the first game in the series to be localized in the West and translated into English. It is also the second game in the series to be released on Game Boy Advance.
In the game exists four unused animations for spells. They are actually all from the game's predecessor Fire Emblem: Fuuin no Tsurugi, much like the Ballista animations. The animations that exist in the game and are yet unused are of Zephiel's ranged sword attack, Roy's Sword of Seals ranged attack, Fa's Divine Dragon breath, and Idunn's Dark Dragon breath, which is mirrored towards the player due to the weapon being enemy only in it's respective game.
The S-ranked bow Rienfleche has an incorrect description in the US localization, claiming it functions like a brave weapon in that it allows the user to attack more often, which is untrue. The European localization fixed this by giving it the correct description. This error is not present in the Japanese release.
In the Japanese release, certain functions in the game are unlocked by linking this game to a copy of Fire Emblem: Fuuin no Tsurugi and transferring data. As Fire Emblem: Fuuin no Tsurugi was not released outside Japan, this functionality was removed from international releases, and instead the content is either available by default or unavailable. Linking with Fire Emblem: Fuuin no Tsurugi achieves the following effects:
-Allows the player to skip Lyn's tale on their first playthrough of the game and start from Eliwood's tale instead. No counterpart function exists in the international versions.
-Two epilogue scenes are unlocked through linking, although both have alternate obtain criteria. A cleared Fire Emblem: Fuuin no Tsurugi save file which achieved the bad ending (where the game ended at Chapter 22) unlocks the first scene with Eliwood, Hector, Roy and Lilina, which can also be obtained by clearing the game nine times. A cleared save with the good endings (where the game ended at the Final Chapter) unlocks the second scene where Zephiel is confronted by Jahn, which can also be obtained by clearing the game eleven times. In the US release of the game, both scenes are in the epilogue by default, but in the European releases the scenes are removed entirely.
This game supports the ability to allow characters to wink and blink during dialogue, though the former is used once in the entire game by Matthew in his recruitment conversation with Guy. Because the wink animation plays at the same speed as the blink animation, most players miss it.
