Just thought I'd add this for completeness' sake:

Seiken Densetsu: Final Fantasy Gaiden - GB
JP: 08 June 1991
NA: 01 November 1991 (released as Final Fantasy Adventure)
EU: no release
It was released in Europe as "Mystic Quest" (no Final Fantasy in the title) in 1993. This is the reason why "Final Fantasy Mystic Quest" (SNES) was renamed "Mystic Quest Legend" in Europe.
