SG-1000

Sega Computer Video Game SG-1000 or simply SG-1000, is a video game console developed and manufactured by Sega and released in Japan, Australia, and New Zealand.

This console was Sega's first entry in the video game console business and provided the basis for the more successful Master System. The SG-1000 was released the same day as the Nintendo Famicom in Japan. The SG-1000 was available in several different variations, including the SC-3000 microcomputer and the redesigned SG-1000 II, also known as the Mark II released in 1984.

Developed in a rensponse to a decline in arcade popularity around 1982, the SG-1000 was created on the advice of Hayao Nakayama, president of Sega Enterprises, Ltd. Shortly after this console release, Sega Enterprises was sold to the CSK Corporation, which was later than followed by the release of the SG-1000 II.

The SG-1000 and its later models support the library of 68 standard ROM cartridge as well as 29 Sega Card games, all of which are fully compatible with the Mark III and the Master System. Due to the release of the Famicom, and the excessively number of consoles present in the market at the time, the SG-1000 was not commercially successful.

List of Sonic games
There's only one Sonic game was ever released for this system. While logically this game wasn't a Sonic game, but this game still technically a Sonic since it was one of the first ever game to include a now-canon Sonic character, Flicky.
