Raiders Of The Lost Ark
Take the Chai and an optional parachute to the flying saucer
mesa area. Walk off the mesa and drop the Chai when Indy starts
to fall. Yar, from the game Yar's Revenge, will appear at the
top of the screen.
Enable the "Yar appearance" code. Then continue game play and
obtain a high score. "HSW2", the initials of programmer
Howard Scott Warshaw, will appear in the inventory after the
game has been completed. Note: The "2" indicates that this
was his second game.
