In 2005 Intellivision Productions announced that new Intellivision cartridges were to be produced. "Deep Pockets and Illusions will be the first two releases in a series of new cartridges for the Intellivision. The printed circuit boards, the cartridge casings, the boxes are all being custom manufactured for this special series." "Illusions" was completed at Mattel Electronics' French office in 1983 but never released. "Deep Pockets Super Pro Pool & Billiards" was programmed for INTV Corporation in 1990 and only released as a ROM file in 1998. However, no cartridges were produced. Previously, in 2000, Intellivision Productions did release new cartridges for the Atari 2600 and Colecovision. "Sea Battle" and "Swordfight" were Atari 2600 games created by Mattel Electronics in the early 1980s but not previously released. "Steamroller" (Colecovision) was developed for Activision in 1984 and not previously released.
