ExtrasThe Hit Squad release of this game for the Atari ST came with a sealed envelope containing game cheat codes "For emergency use only".
TRS-80 CoCo versionThe TRS-80 CoCo version was one of only two cartridges that Radio Shack/Tandy put out which used a ROM >32KB (the normal technical maximum for a CoCo 3 cartridge). Greg Zumwalt designed "super cartridge" hardware that included a built in MMU (Memory Management Unit) to break this barrier, and used 128KB of ROM with RoboCop .
The other game using this hardware was Predator, with 64KB of ROM. In an article explaining the hardware in Rainbow magazine (TRS-80 CoCo's largest and longest running dedicated magazine), Zumwalt explained that he had prototyped a second version of the super cartridge that could handle up to a 512KB ROM, but no games were ever released using this hardware (probably due to costs and the CoCo nearing the end of its life at Radio Shack).
