Mattel Electronics, the maker of the Intellivision, sold its Atari 2600 games under the M Network label, and most of them are listed on that page. The two games here are Mattel 2600 titles that were finished around 1983 but shelved, partly because they needed two players.

Intellivision Productions finally released both on cartridge in 2000.
