Deep Pockets: Super Pro Pool and Billiards
Programming pool was a challenge: with 16 balls on the table, the game requires more than the Intellivision's 8 moving objects. At Mattel Electronics, Marketing had rarely allowed programmers to multiplex objects because they objected to the resulting screen flicker (the one exception had been the fireballs in Masters of the Universe: The Power of He-Man, since it made sense for them to flicker). But for pool, it was the only practical solution.
Producer Dave Warhol tapped math-whiz Rick Koenig (Motocross) to work out the multiplexing and movement of the balls. Steve Ettinger (Hover Force) did the overall game design and program, becoming an expert in all the variations of pool and billiards in the process.
By the time the game was completed, however, INTV Corporation had fallen into financial difficulties and was unable to pay for it. Realtime Associates retained ownership of the game and it was never released. The last game for the Intellivision system completed, it carries a 1990 copyright date, making Intellivision the only cartridge-based game system to have software produced for it in three separate decades (the earliest games carry a 1978 copyright date).
Intellivision Productions included the ROM image on the Intellivision Lives! CD-ROM.
In 2019, Blue Sky Rangers, Inc, finally issued an official cartridge release.
