Asmik Corporation published and ported several notable titles in the late 1980s, including the Sega Genesis RPG Super Hydlide and the NES first-person RPG Dungeon & Magic. They also published the 3D shooter Cosmic Epsilon, the PC Engine port of Shinobi, and Deep Dungeon. The company introduced its dinosaur mascot, Boomer, in the 1989 Game Boy title Boomer's Adventure in Asmik World.
Established in 1985 as a joint venture between Sumitomo Corporation, Tokyo Broadcasting System, and Oricon, the publisher initially targeted Japanese home computers and consoles. The company's early software catalog featured sports simulations, including
Tennis (1984) and
Tennis (1986), which helped secure a foothold in the emerging domestic gaming market.
Asmik quickly diversified into role-playing and action genres. They published the influential first-person RPG
Deep Dungeon (1986) for the Famicom Disk System, establishing a template for their later localization and release of
Dungeon & Magic (1989). The company frequently collaborated with external developers to bring technically ambitious projects to market. This included the pseudo-3D rail shooter
Cosmic Epsilon (1989) and the Sega Genesis action-RPG
Super Hydlide (1989).
Through licensing agreements, Asmik also brought major arcade properties to home consoles, notably publishing the PC Engine port of Sega's
Shinobi (1989). To unify their brand across these diverse genres, the publisher introduced a signature character with
Boomer's Adventure in Asmik World (1989), positioning the titular dinosaur as a corporate mascot across subsequent puzzle and platforming releases.
