Sega Master System Console

Online emulated version of Sonic the Hedgehog was originally developed for the Sega Master System a third-generation 8-bit home video game console manufactured by Sega. It was originally a remodeled export version of the Sega Mark III, the third iteration of the SG-1000 series of consoles, which was released in Japan in 1985 and featured enhanced graphical capabilities over its predecessors. The Master System launched in North America in 1986, followed by Europe in 1987.
The original Master System models use both cartridges and a credit card-sized format known as Sega Cards. Accessories for the consoles include a light gun and 3D glasses that work with a range of specially designed games. The later Master System II redesign removed the card slot, turning it into a strictly cartridge-only system and is incompatible with the 3D glasses.

The Master System's main CPU is a Zilog Z80A, an 8-bit processor running at 4 MHz. It has 8 kB of ROM, 8 kB of RAM and 16 kB of video RAM. Video is provided through an RF switch and displays at a resolution of 256 × 192 pixels and up to 32 colors at one time from a total palette of 64 colors; the graphics chip was designed by Sega for the Mark III.
