INTELLIVISION CARTRIDGE [ #8800]
Based on the Namco arcade game
Produced by Atari
Release version prepared by Realtime Associates for INTV Corporation
Program: Mark Kennedy
The Intellivision version of Dig Dug had been programmed at Atari by former Mattel Electronics programmer Mark Kennedy (). The game had not been fully debugged, though, when Atari closed up their Intellivision division in 1984. INTV Corp. negotiated the rights three years later to release the cartridge for the first time.
The source code no longer existed, but Producer Dave Warhol uploaded the code from a prototype of the game still in Mark's possession. Working with the disassembled code, Mark fixed the game's remaining bugs and removed the Atari title screen.
