 Ocean developed and published a version for the Game Boy in 1990.In 1989, Ocean released a different "Robocop" game that only bore a loose resemblance to the arcade; this version was produced for the Commodore 64, MSX, ZX Spectrum, Tandy Color Computer 3 and Amstrad CPC, as well as PC compatibles, meaning that PCs ended up with two entirely different "Robocop" games for North American and European audiences.As with many Ocean C64 titles, both cassette and disk versions were released; the North American release (also published by Data East) was based on the disk version.
