History and Trivia


The Sega Master System or SMS for short, is an 8-bit cartridge-based video game console that was manufactured by Sega.

Its original Japanese incarnation was the SG-1000 Mark III, which was released in Japan in 1985, as a successor of the SG-1000 Mark I and Mark II. The system had a second release in Japan, in 1987, under the new Master System name: this Japanese Master System included a built-in 3D glasses adapter, rapid fire, and a Yamaha YM2413 FM sound chip, all of which were separate accessories for the Mark III.

In the United States, the system was released under the name Sega Master System in June 1986, with a redesigned case compared to the SG-1000 Mark III. Having been released less than a year after the Nintendo Entertainment System, the Master System became its natural competitor in the 8-bit consoles market. However, despite being a more technically advanced piece of hardware than the NES, the Master System did not attain the same level of popularity among U.S. consumers.

In early '90s, Sega designed the Master System II, a newer console which was smaller and sleeker but which, to keep production costs low, lacked the reset button and the card slot of the original system. In an effort to counter Nintendo's "Super Mario Bros.", the new system included "Alex Kidd in Miracle World", or later "Sonic the Hedgehog", playable without any cartridges. Sega marketed the Master System II heavily; nevertheless, the unit sold poorly in North America.

In Europe, the Master System was very successful with Sega marketing the console in many countries, including several in which Nintendo was not selling its consoles. As a result, while SMS support was dropped around 1992 in North America and Japan, it was supported until 1996 in Europe.

The system ultimately failed to topple its Nintendo competitor, but has enjoyed over a decade of life in secondary markets, especially in Brazil where it was manufactured by TecToy which also released many exclusive conversions.

== Media input ==

One of the most unique features of the Sega Master System was its dual media inputs: one cartridge slot and one card slot. The card slot accepted small cards about the size of a credit card. Most cards were games, but one card served an entirely different purpose; indeed, the 3-D glasses plugged into the console via the card slot, and allowed 3-D visual effects for specially designed cartridge games.

Peripherals

* Standard controllers: The Master System controller was considered extremely durable. However, there were only 2 buttons, one of which additionally performed the function of the traditional "Start" button; the pause button was on the game console itself. The original controllers, like Sega's previous systems, had the cord emerging from the side; during 1987 they changed the design to the now-typical top emerging cord. These early controllers also included a screw-in thumbstick; these were later omitted and the D-pad on the controller was redesigned without a screwhole for the thumbstick. When the game Street Fighter II was released (in Brazil only), a new six-button controller similar to the Sega Mega Drive controller was also released. The current Brazilian Master System consoles comes with two of those six-button controllers. The controller used a standard Atari-style 9-pin connector and could be connected without modification to all other machines compatible with that standard, including the Atari 2600, Commodore Amiga, Atari ST, Commodore 64, Amstrad CPC and ZX Spectrum with Kempston interface or similar.

* Light Phaser: The Light Phaser is a light gun which can be used with a limited number of games.

* 3-D Glasses: The 3-D Glasses used a shutter system to close the left and right lens rapidly to create a 3D effect. Such a system allows 3-D graphics in full color. A disadvantage is that it halves the effective frame-rate, which some users can perceive as flicker. The Master System glasses can only be used in the original Master System since they hook up directly to the card port not found in the Master System II. Only six Master System games were 3-D compatible.
