Zone was ported to the Sega Master System, MSX, Nintendo Entertainment System, Sharp X68000, and PC Engineall with similar gameplay. For example, the Master System version lacks some features such as the radar that indicates the location of the bases or a gauge that indicates energy level, and two of the bosses were replaced by original ones. Two different versions were released for the Famicom and NES. The Japanese version was released in 1987, developed and published by Sunsoft. The American version was released in 1989, developed by Pixel and published unlicensed by Tengen. In 1997, Fantasy Zone was released in the Sega Ages series in Japan for the Sega Saturn. Fantasy Zone was re-released as an enhanced remake for the PlayStation 2, again in the Sega Ages series. Although similar in appearance to the arcade version (even incorporating the original arcade sounds), this version uses polygons instead of sprites and adds some stages, including bonus levels with the viewpoint behind Opa-Opa as he tries to collect coins from any boss that was defeated at the moment; this game mode is very similar to Space Harrier, or the unreleased Space Fantasy Zone. This version was released in North America in the Sega Classics Collection. Fantasy Zone was released for mobile phones in 2002 in Japan and in August 2003 in the United States. Due to hardware limitations, this version was divided in three different parts. The Master System version was re-released in Japan for the Virtual Console on March 11, 2008, for Europe and Australia on April 11, and in North America on April 14. On September 18 , the final Sega Ages disc was devoted to the series, Fantasy Zone Complete Collection. Instead of a 3D remake, it compiles all of the games in the series, including spin-offs, all of Sega's own versions, and a remake of Fantasy Zone II for System 16 hardware. The original arcade version is unlockable in Sonic's Ultimate Genesis Collection. A 3D port of the game was released on March 19, 2014 for the Nintendo 3DS titled 3D Fantasy Zone: Opa-Opa Bros. New features of the 3DS port involve stereoscopic 3D visuals, adjustable difficulty settings, the ability to save the game, the ability to switch to the Japanese versions and US versions of the game, a Stage Select feature, and a new mode which involves the player playing as Upa-Upa, Opa-Opa's brother.
