"killer instinct" is the first arcade game to use an internal hard disk drive in addition to the game's roms. this allows it to store massive amounts of data thereby giving it the ability to have more detailed graphics than other games of this genre. the game uses pre-rendered sprites and backgrounds, created with silicon graphics computers. the backgrounds are stored as a "movie" which adjusts frames based on the players' movements. "killer instinct"s r4600 processor is clocked at 100 mhz. unlike most arcade games of the time, "killer instinct" does not display which version number of the game is being played.
