In Europe, Konami released ports of "Jackal" for the ZX Spectrum, Amstrad CPC and Commodore 64 in 1988. An MS-DOS version was released in North America in 1989 alongside a different Commodore 64 port. These versions were roughly based on the arcade game. A ROM image of the NES "Jackal" is included in the Windows PC compilation "Konami Collector's Series: Castlevania & Contra" released in 2002 in North America. However, the game is inaccessible by legitimate means and can only be found by extracting it from the executable. The game is virtually identical to the original NES release, aside from the updated copyrights date.
