Zero Wing was first ported to the Sega Mega Drive by Toaplan and was first published in Japan on 31 May 1991 and later in Europe by Sega in July 1991. The game was later converted to the PC Engine CD-ROM² add-on and was published exclusively in Japan by Naxat Soft on 18 September 1992. The Japanese release is able to play fine on American Sega Genesis consoles. Like most early titles it had no region protection, nor had the European release been PAL-optimized. To expand the plot, the Mega Drive version added an introductory sequence to the game. This introduction does not appear in the arcade original nor in the PC Engine CD-ROM² versions; rather, a different intro takes place with a blue-windowed ZIG. The PC Engine CD-ROM² added two new levels — 5th (Deeva) and 10th (Vacura).
