The Atari 2600 games market in Brazil in the 1980’s was very large and very active. However it was overwhelmingly populated by bootlegs and the bootlegging companies tended to play free and loose with American brand names. One such company, Canal 3, released most of their titles under the brand name “Intellivision” (same logo and everything) even though the games were for the Atari 2600. Miner 2049er was one of the games they bootlegged and is almost certainly the source of the (false) rumor that there was an Intellivision version of the game.
Another was released by “Pop Video”
