MegaBoy by Dynacom many overseas companies during the classic game era thrived on selling ripoff pirate games in their native countries.
A few companies, however, managed to innovate, and Brazil-based Dynacom was one of them.
Much like other companies in South America, Dynacom got its start in the early 80's by selling (illegal) 2600 clones and ripoff games in Brazil. Later in the decade, however, they briefly test marketed a handheld Atari 2600 clone named Megaboy. Their aim was to market this system for children's learning purposes. This was evident by the pack-in cartridge, which was a 4-in-1 educational game.
