Legend of the Mana Sword
Seiken Densetsu: Final Fantasy Gaiden · 聖剣伝説 ～ファイナルファンタジー外伝～ · Mystic Quest
A long-running improvement project for Final Fantasy Adventure that fixes many of the original's bugs, revises the script with the Japanese text and later Mana lore in mind, and adds an optional colorization.
What it changes
Legend of the Mana Sword takes its name from the Japanese title of the game and aims to bring the first Mana game closer to the rest of the series. The script is revised using the Japanese original and the lore of the later games, and a long list of bugs is fixed, including the notorious Heal spell bug. The hack also adds a new title screen and a Super Game Boy border, and it is built on a community disassembly of the game, which made larger changes possible.
Latest release
The October 2026 release keeps polishing: more puzzle-room glitches are prevented, extra damage no longer carries over from one boss to the next, healing ponds now cure status effects, Stone is cured after the Medusa fight, dialog speed is more consistent, the Select menu no longer covers the status bar, and many small graphical and sound issues are fixed.
Versions
There are separate patches for playing with the hero named Duke or the heroine named Amanda, and each comes in a Game Boy Color version with colorization that is still in beta.
