There were two versions of Theme Park sold for Amiga computers. One was an AGA version of the game with 256 color graphics and was pretty much the same as the PC version. The other version was a trimmed down version for non AGA stock Amigas like the A500.
CD version of the game contains several enhancements in regard of disk version. Introduction sequence is played in full screen and during the game there are 15 animation cutscenes presenting possibilities of the facilities you may build. They can be played after using magnifying glass icon over the buildings. Also, the animation for the Flight Simulator Ride contains gameplay footage from another Bullfrog game, Magic Carpet (1994).
While the original Mac version of Theme Park can be started even on late Macs with OSX 10.4 "Tiger", the game has no speed restraints, so that a year in-game may pass in a few seconds.
