Eiyuu Densetsu Saga

Fearing the wrath of the dragon, the king sends a young girl to the Northern Valley as a sacrifice in hopes to appease it. The Northern Valley is unknown to most, but there is one brave man who is willing to step up and save the girl called Linda. However it is said that only a legendary weapon can slay the creature...

Not to be confused with Falcom's Eiyuu Densetsu RPG series, Eiyuu Densetsu Saga (Legendary Hero Saga) was originally a PC98 game developed by Arrowsoft and published by Microcabin back in 1984. Although known as a graphic adventure game (or 'Role Venture Comic' as Microcabin calls it), it is probably more accurate to call it a dungeon crawler as you spend the entire game navigating through a labyrinth. The game was released for several computer platforms with some differences between them, such as a different map layout.
