Ikari Warriors/Versions

Amstrad CPC
Ported and published in the United Kingdom by Elite Systems in 1987. Comparable to the Elite Commodore 64 version in quality.

Atari 2600
Ported and published by Atari in 1989, primarily in the United Kingdom, but in limited amounts around the United States. Poorly received, this was just too great a stretch for the limited machine.

Atari 7800
Ported by Imagineering Inc. and published by Atari in 1989. This version was actually fairly well received, in some cases reviewed more favorably than the more common NES version, particularly on account of its much more responsive controls.

Atari ST
Ported and published in the United Kingdom by Elite Systems in 1988. Comparable to the Commodore Amiga version in quality.

Commodore 64
Two different versions of the game were made. Data East obtained the computer publishing rights to the game in the United States and developed a conversion for the Commodore 64 and IBM-PC in 1987 when the game was popular. However, it was quickly outshined by the substantially higher quality version developed by Elite Systems for the United Kingdom in 1988. Players generally consider the Elite version to be the only version worth playing.

Commodore Amiga
Ported and published in the United Kingdom by Elite Systems in 1988. Comparable to the Atari ST version in quality.

Famicom / NES
SNK published the game first in Japan in 1986, and in the United States in 1987, and later in Europe in 1989. The game's conversion was actually handled by Micronics, the infamous group behind other notorious ports such as Ghost 'n Goblins and 1942. In general, this conversion is plagued by its slow gameplay and poor controls. To compensate for the lack of a rotary joystick, the characters had to actually turn through every available direction. As result, they are incapable of turning "on a dime"; they tend to move slowly around some point on the ground. Massive build up of enemies and mines create inescapable situations, and three more stages were added on to the already long stage present. However, more power-ups and varieties of enemies are present, and the ability to pilot a helicopter was added to the game.

The version has included a cheat code,, that allows you to respawn after you died (but only until the end of stage 3. At the title screen, you can also enter a stage select code:  and.

MSX
Ported and published by SNK themselves in Japan in 1987, and is the only game that SNK would ever publish for this platform. The game requires MSX2 hardware to run, and is considered a pretty good conversion.

MS-DOS
As mentioned above, Data East obtained the computer publishing rights to the game in the United States and developed a conversion for the Commodore 64 and IBM-PC in 1987 when the game was popular. The PC conversion ran on MS-DOS machines and could be played in 4 color CGA or 16 color EGA.

Sinclair ZX Spectrum
Ported and published in the United Kingdom by Elite Systems in 1988. Generally the weakest looking of all the Elite conversions, due to hardware limitations.
