The game was ported to several home systems, including the Apple II, Atari ST, Amiga, Amstrad CPC, Commodore 64, ZX Spectrum, MSX and PC DOS in 1988. Most of the ports were done by UK-based Imagine Software; Quicksilver Software developed the Apple II and PC ports. On July 14, 1989, a NES/Famicom port was developed by Data East and published in Japan by Namco as "DragonNinja". In North America, the same version was released the same year by Data East USA simply as "Bad Dudes", featuring an illustration by Marc Ericksen. In Europe, it was released in 1990 by Ocean Software as "Bad Dudes Vs. DragonNinja", although the ""Bad Dudes Vs."" was heavily de-emphasised in the cover art, and the home versions (excluding the NES version) were simply titled "Dragon Ninja" in-game, resulting in the game commonly being known by the latter title (including among the European gaming press of the time).
