Yea sort of, but its quite confusing. There are two different games, which has been renamed in each region causing many confusion on the long run which game is which.
First of you have the gameboy title, called final fantasy adventures. Its the one that plays like a zelda game and its also the one that has been remade into the first mana game. It has been released under the names:
JP -> Seiken Densetsu: Final Fantasy Gaiden
USA -> Final Fantasy Adventures
EU -> Mystic Quest
Then you also have an RPG with a battle system like final fantasy itself. This one is released for the SNES and has bee released under the names:
JP -> Final Fantasy USA Mystic Quest
USA -> Final Fantasy Mystic Quest
EU -> Mystic Quest Legend
