Games for the console came in two formats; ROM cartridges and SEGA Game Cards. The cards held only 256 kilobits of data (cartridges held at least 4 times that amount, e.g. the early "mega cartridge" games with 1 Mbit / 128 kbit), but were cheaper to manufacture and sold for less than the carts did. The console also featured games built into the system BIOS that played whenever a cart or card was not inserted; the different models of the console each featured different built-in titles. The Mark III was also backwards compatible with SG-1000 software.
In 1986 and 1987, a redesigned version of the console, now branded as the Master System, was released in North America, Europe, Brazil and South Korea, and featured the addition of a built-in Yamaha YM2413 FM sound chip, a rapid fire unit and 3-D glasses; all of these had been separate accessories for the SG-1000 Mark III.
Despite a strong start, selling 1 million units in its first year on sale in Japan, neither the Mark III nor its Master System variant ever posed a serious challenge to Nintendo's near-total domination of the Japanese console market.
The last licensed title in Japan was Bomber Raid, released by SEGA on February 4, 1989.
Technical details[edit | edit source]
The system was backwards compatible with earlier SG-1000 titles. As well as the standard cartridge slot, it had a built-in slot, formerly known as expansion slot for SEGA Game Cards, which were physically identical to the cards for the SG-1000 "Card Catcher" add-on. While in Japan there were many titles in this format published for both the SG-1000 and Mark III, only a few were published in the West.
Master System game cartridges released outside Japan had a different shape and pin configuration from the Japanese SG-1000 Mark III cartridges. This may be seen as a form of regional lockout.
