The Neo Geo (Greek for 'New World'), stylized as NEO•GEO, is a video game platform released in 1990 by Japanese game company SNK Corporation. It was initially released in two ROM cartridge-based formats: an arcade system board (Multi Video System; MVS) and a home video game console (Advanced Entertainment System; AES). A CD-ROM-based home console iteration, the Neo Geo CD, was released in 1994. The arcade system can hold multiple cartridges that can be exchanged out, a unique feature that contrasted to the dedicated single-game arcade cabinets of its time, making it popular with arcade operators.
The Neo Geo was marketed as the first 24-bit system; its CPU is actually a 16/32-bit 68000 with an 8-bit Z80 coprocessor, while its GPU chipset has a 24-bit graphics data bus. It was a very powerful system when released, more so than any video game console at the time, and many arcade systems such as rival Capcom's CPS, which did not surpass it until the CP System II in 1993.
