Pitfall II: The Lost Caverns
is probably the most technically advanced
of all the Atari 2600
games ever written. It features an extremely large, well designed scrolling
cavern with well-animated creatures and colorful backdrops.
Pitfall II was written by David Crane of Activision. He incorporated a separate sound chip into the cart, which is used to generate the extremely catchy game music. It is the only 2600 game that utilized this sound chip. As a result, 2600 emulators have to emulate this chip specifically for the game.
The Atari 5200 version of Pitfall II features an additional level.
