Super Nintendo Entertainment System

The Super Nintendo Entertainment System, also known as Super Nintendo, Super NES or SNES, was a 16-bit video game console released by Nintendo in 1990. In Japan and South-East Asia, the equivalent was known as the Super Famicom (aka SFC).

The SNES was Nintendo's second home console, following the Nintendo Entertainment System. Whereas the earlier system had struggled in the PAL region and large parts of Asia, the SNES proved to be a global success, albeit one that could not match its predecessor's popularity in Southeast Asia and North America—due in part to increased competition from Sega's Mega Drive console (released in North America as the Genesis). Despite its relatively late start, the Super Nintendo Entertainment System became the best selling console of the 16-bit era.

Dragon Quest titles for the SNES

Dragon Quest I & II - a remake compilation of the Japanese Famicom games, Dragon Quest and Dragon Quest II.
Dragon Quest III - a remake of the Japanese Famicom game, Dragon Quest III.
Dragon Quest V
Dragon Quest VI

None of these received official English localizations until after the title had been remade for Game Boy/Game Boy Color or the Nintendo DS.

Other games

Torneko no Daibōken: Fushigi no Dungeon - this is a rogue-like spin-off of the Dragon Quest series starring the merchant Torneko from Dragon Quest IV in a quest to get the ultimate treasure by venturing forth into a large "Mysterious Dungeon" that is many floors deep. It also was the first game in the prolific Fushigi no Dungeon/Mysterious Dungeon series, which has long since expanded to include games outside of the Dragon Quest umbrella. It has never been released outside of Japan.

The Game Boy Color port of Dragon Quest I & II, as well as Dragon Quest Monsters and Dragon Quest Monsters 2 can also be played on the SNES through the use of the Super Game Boy cartridge.
