если б всё ограничивалось сеговской, нинтендовской и писишной версией
Была ж ведь ещё как минимум на 3DO, PC-CDROM, Sega CD, Acorn Archimedes, Amiga, Apple Macintosh, Atari Jaguar, CD-i, FM Towns. И это оффициально. А ещё точно был порт на GBA (который вроде уже считается оффициальным), на смартфоны, ну и на PC не так давно выходил римейк с поддержкой высоких разрешений
Где-то об отличиях читал но не помню где, вот какие-то мелочи нашёл :
By default, the MS-DOS version has an extended introductory sequence and more minor cut scenes than the Amiga version (such as when picking up items). In the Amiga version the user can see these scenes by enabling them (although with few seconds of delay every time the animations load) or by playing the game entirely from the hard drive. The game was originally released on 3.5" floppy disk for MS-DOS, re-releases on CD-ROM for systems such as 3DO, CD-i, Jaguar, PC and Sega CD featured redone cinematics with new graphics as well as audible dialogue throughout and new sounds and music.
In North America, the Sega Genesis, Sega CD and Super Nintendo versions featured a Marvel Comics comic book within the manual in order to explain the initial story. The European release on Sega Mega Drive, Sega Mega-CD and Super Nintendo omitted the comic and featured a textual story instead.
