The Master System III was released in 2003 by Brazilian toy manufacturer Tec Toy. It is exclusive to the Brazilian market where it is still a popular system. Externally the console is the same as the [Master System II](/museum/sega-master-system-ii/) apart from the colour, which is a very light grey instead of being dark grey.

In fact the Master System III is still on sale to this day. The current version, Master System 3 - 120 Super Jogos Na Memória, comes with 120 games built in.
