It had a Motorola 68000 CPU at 7.6 MHz and a Zilog Z80 at 3.58 MHz. In other regions, it was known as the '''Mega Drive'''. It had several add-ons, including the Sega CD (a CD add-on, called Mega CD outside America) and the 32X (a 32-bit, cartridge-based add-on).

The Sega CD was released on October 15, 1992 and retailed for {{Inflation|USD|299.99|1992}} and had a Motorola 68000 CPU at 12.5 MHz and 64 kbit of RAM. The Sega 32X was released on November 21, 1994 for {{Inflation|USD|159.99|1994}}. It had 2 SH-2 RISC CPUs at 23 MHz with 256KB of RAM and 256KB of VRAM. Genesis emulation is very good, with a high degree of game compatibility (many of them claiming nearly 100% compatibility with commercial games, including Virtua Racing). They are available on many platforms. Many Genesis emulators also feature compatibility with the [[Master System emulators|Sega Master System]] (SMS), and the [[Master System emulators|Game Gear]] (GG) as well as earlier Sega consoles. Genesis-based arcade boards and the Sega Pico are still sketchy, however.
