Tectoy S.A. (formerly Tec Toy Indústria de Brinquedos S.A.) is a Brazilian electronics company founded in 1987. They are best known as Sega's representative for the Brazilian market.
In 1997, Tectoy developed and published a port of Street Fighter II for Sega's Master System console. This was the only authorized port of the game for a third generation home console.
Tectoy also co-created (with telecom giant Qualcomm) the Zeebo console, which received a port of Resident Evil 4 (based on the game's mobile version). A port of Street Fighter Alpha was also announced, but it was cancelled due to the system's commercial failure.
