Dragon Slayer I is another entry in the Dragon Slayer series and appeared on the Nintendo Game Boy in Japan. As a Game Boy game, it is likely an action RPG that would have had to adapt its gameplay to the hardware's technical limitations. The game would likely share narrative and gameplay elements with other titles in the franchise, but with a scale and style tailored for the portable platform.
