This teeny-tiny article needs some work. You can help us by expanding it.

The Sega NAOMI 2 is an arcade board developed by Sega and is a successor to Sega NAOMI hardware. It was originally released in 2000, and stands as a beefed up version of the NAOMI specification. It is also fully backwards compatible with its predecessor.

The NAOMI 2 is by and large a more powerful version of the NAOMI, adding a secondary CPU and GPU, as well as increasing the graphics memory. This leads to games with roughly twice as many polygons as a NAOMI game with faster rendering times, though everything else remains largely the same.

As with the NAOMI, the NAOMI 2 was also available in GD-ROM and Satellite Terminal variants.
