A version of Hook for the Sega Master System was developed, but not released. In terms of graphics, it is mostly identical to the Game Gear version. A ROM image made from a prototype cartridge is available on the Internet.
Hook is the 1991 Steven Spielberg movie which tells the story of a bureaucratic grown-up Peter Pan (Robin Williams) in need to rescue the magic of younger years to in order to defeat Captain James Hook (Dustin Hoffman) and save his children. To accomplish this task, he has the help of Tinkerbell (Julia Roberts) the lost boys.
Between 1991 and 1992 a series of Hook conversions to games were born, developed by different game companies.
Hook was released for PC and Amiga in 1991 by Ocean as a Monkey Island-like graphic adventure game. Ocean also released an action game for NES and Game Boy, which were basically the same.
In 1992, Sony ImageSoft developed another action game named after the movie. Hook for Super NES, Sega CD and Genesis were 16-bit, colorful games. An 8-bit version of the Sony Imagesoft game was also released for Game Gear (and were totally different from NES and Game Boy versions).
There was even an Arcade (coin-op) version of Hook, released in 1992 by Irem. It was a beat 'em up side-scrolling game, just like Final Fight and Double Dragon. It supported 4 simultaneous players (characters available were Peter Pan, Rufio, Ace and Pockets, each one with his own characteristics) for beating up the pirates.
In all of them, the player takes control of middle-aged Peter Pan in his mission to find Captain Hook and save his children. In spite of that, all the three versions have totally distinct graphics, sounds and gameplay.
