A
Game Boy version was developed by Xanth, and published in 1991 by
Bullet-Proof Software, with the title
Faceball 2000. James Yee, owner of Xanth, had the idea of porting the 520ST application to the Game Boy. George Miller was hired to rewrite the AI-based drone logic, giving each drone a unique personality trait. This version allows two players with a
Game Link Cable, or up to four players with the Four Player Adapter. It is often rumored that the Game Boy version would allow up to 16 players by daisy-chaining Four Player Adapters, which is not the case. According to programmer Robert Champagne, the original game's code does contain a 16-player mode, but it required a special adapter that was planned to be bundled with the game, to create a "chain" of link cables. The 16-player mode and the adapter were announced in the April 1991 issue of
Nintendo Power; however, Nintendo did not allow the adapter's release, so the 16-player mode cannot be enabled using original Game Boy systems. Later, a method was discovered to daisy-chain Game Boy Advance link cables to allow up to 15 players. In 2024, electrical engineer Zarithya was able to produce a 16-player adapter that replicated the functionality of the original adapter intended for the game, discovering that due to an
off-by-one error, more than 15 players would never have been possible in the original release of the game even with compatible hardware. She was then able to modify the ROM to support up to 16 simultaneous players, and successfully start a 16-player match. She and others created two patches for the game, one to fix the 16-player functionality only, and another to upgrade the game to include Super Game Boy and Game Boy Color support (called "Faceball 2000 DX"), and released them on GitHub. A
Super NES version, also titled
Faceball 2000, was released in 1992, supporting two players in split-screen mode. This version features completely different graphics and levels from the earlier Game Boy version. A variety of in-game music for this version was composed by
George "The Fat Man" Sanger. A
Game Gear version, also titled
Faceball 2000, was released to the
Japanese market by
Riverhill Soft. It is a colorized version of the monochrome Game Boy version, supporting two players with two handheld consoles connected by the Gear-to-Gear Cable. A
PC Engine CD-ROM version, titled only
Faceball (フェイスボール), was released in Japan by Riverhill Soft.
Unreleased ports A port of
MIDI Maze for
Atari 8-bit computers was developed by Xanth, but cancelled circa 1989. A prototype was eventually found and the ROM was released. According to Robert Champagne, other unreleased ports were worked on at Xanth, including IBM PC and NES. A port for Nintendo's
Virtual Boy console, to be titled
NikoChan Battle (ニコちゃんバトル) in Japan, was almost completed, but canceled as the system was discontinued in late 1995. A prototype was found in 2013, and the ROM was subsequently released. ==Reception==
