"Dragon Slayer IV: The Drasle Family" was first released for the MSX2 home computer on July 10, 1987, developed and published by Nihon Falcom. The game is sometimes misattributed to Quintet due to a reference in the game's ending credits, but composer Yuzo Koshiro has confirmed this is pure coincidence, since the company wasn't formed until two years later.
