In 1993, it was ported to Amiga and Mega Drive/Genesis. The Amiga floppy disk port is nearly identical in interface and game play to the PC version, albeit with less detailed graphics and frequent disk swapping (the game came on five disks). Save games are stored on a specially formatted disk and the game could also be installed to hard drive. In the Amiga version the player is limited to 32 units, but patches exist to allow the DOS version to have 255 units created and managed.
