Other aspects of the game remain unchanged in the GBA port the difficulty level is the same as in Dawn of Souls.
In addition, just like in the GBA version, a bestiary and a BGM music player may be unlocked. There is a brand new dungeon that has been given the name “Arcane Sanctuary.” The jail uses a “word memory system,” based on the word that is selected, a different set of foes and an entirely new experience will be presented to the player. In addition to that, it features illustration galleries created by Yoshitaka Amano. Additionally, the CG opening sequence from the PlayStation edition has been remade in a 16:9 aspect ratio. Still, it also has new and enhanced graphics, a 16:9 screen format with letters that are easier to see, and higher-quality music and sound. Dissidia 012 is the precursor to Square Enix’s title Dissidia: Final Fantasy, released in 2009, and it also includes the tale of the original game, which has been retold to accommodate the game’s new mechanics.
It includes all the bonuses available in the Game Boy edition, including Soul of Rebirth. This makes this remake similar to the previously re-released Final Fantasy, also based on the Game Boy Advance version. This remake of the original Final Fantasy II is built around the Game Boy Advance version of the game, which was based on the earlier WonderSwan Color remake.
