The hardware for these games consisted of a laserdisc player linked to a processor configured with interface software that assigned a jump-to-chapter function to each of the controller buttons at each decision point. Much as a "Choose Your Own Adventure" book might say "If you turn left, go to page 7. If you turn right, go to page 8", the controller for "Dragon's Lair" or "Cliff Hanger" was programmed to go to the next chapter in the successful story if a player activated the correct control, or to go to the death chapter if they activated the wrong one. Because laserdisc players of the day were not robust enough to handle the wear and tear of constant arcade use, they required frequent replacement. The laserdiscs that contained the footage were ordinary laserdiscs with nothing special about them save for the order of their chapters and, if removed from the arcade console, would play their video on standard, non-interactive laserdisc players.
