During the 1980s, the Brazilian government required outside-developed technology to be re-developed within the country for soverignty reasons. Details of the deal made with US-based Mattel are not known, but Digiplay was the entity responsible for localization of hardware labels and references, game text, boxes, overlays, and advertising.
Digiplay had a "pirate competitor" in the Carioca company distributing the IntelliGame bootleg games, manufactured by VLS. Foundd in 1984, it sold photocopied manuals and Portuguese-summarized materials for rental stores. The price was much less than official Digiplay content, and the games were exactly the same (some were even multicarts with hardware switches).
