"The Neo Geo Pocket Color (shortened NGPC), is a 16-bit color handheld game console by SNK. It was their last console ever. It was released on March 16, 1999 in Japan, August 6, 1999 in North America, and some time in 1999 in Europe.

The Neo Geo Pocket Color was designed to replace SNK's original Neo Geo Pocket monochrome handheld, which debuted in 1998 in Japan. In 2000, following SNK's purchase by Japanese pachinko manufacturer Aruze, the Neo Geo Pocket Color was dropped from both the North American and European markets. It did, however, last until 2001 in Japan, with a total of 2 million units sold."
