Rygar/Versions

Amstrad CPC
Ported by Probe Software and published by U.S. Gold for the United Kingdom in 1987.

Atari LYNX
Ported by Haehn Software Productions and published by Atari in 1990. Aside from the considerably smaller screen resolution, this conversion was considered quite faithful to the arcade game. It contains 23 levels as opposed to the original's 27.

Commodore 64
Ported by Probe Software and published by U.S. Gold for the United Kingdom in 1987.

Sega Master System
Ported by Salio and published by Sega for Japan in 1988 as Argus No Juujiken. Not exactly a direct port of the arcade game, but much closer in gameplay to the original than the NES conversion. The lower tunnel on the screen can be run through on occasion. Fights against the Giant Demons occur as boss fights.

Sinclair ZX Spectrum
Ported by Probe Software and published by U.S. Gold for the United Kingdom in 1987.
