Phantasy Star Fukkokuban © 1994 SEGA Enterprises, Ltd.
GAME ID: G-4534
Released on April 02, 1994 in Japan. It was never exported outside Japan.
This Mega Drive version of Phantasy Star is in fact nothing more than the Mark III ROM in a Mega Drive cartridge, with enough start-up code to put the system into its Mark III backwards compatibility mode; it can be regarded as a Mark III converter integrated into the game.
