The Master System 3 Collection from 2007 is a version of the Sega Master System released by Tectoy exclusively in Brazil in 2007. While similar in apperance to previous units (sharing a plastic shell with the redesigned Master System II, dating back to 1990), this version lacks support for game cartridges, meaning only the "131" built-in games are playable. The cartridge slot cover still exists, but if opened it will reveal an empty space. Tectoy would abandon this design with the release of the Master System 3 the following year. In order to count 131 games, Pense Bem counts as 10 and 20 em 1 counts as 20 games.
