Hyper Neo Geo 64

The Hyper Neo Geo 64 is an arcade system board created by SNK and released in 1997. Planned as a successor of the popular Neo Geo, it never managed to match its success.<ref>Template:Cite web</ref> Only seven games were produced, none of which proved particularly popular.<ref>Template:Cite web</ref> It was the only SNK arcade board capable of 3D rendering, conceived to bring SNK into the 3D era that had arisen during the mid-1990s.

History

The system was first announced in late 1995, and planned for release in late 1996.<ref>Template:Cite magazine</ref> It was officially unveiled at the February 1997 AOU show, though all that was demonstrated at the show was a videotape containing a few seconds of footage of Samurai Shodown 64, which SNK announced would be the first game for the system.<ref>Template:Cite magazine</ref> By mid-1997 test units were on display in Japan.<ref>Template:Cite magazine</ref>

The system was released, only in arcade form, in September 1997, featuring a custom 64-bit RISC processor, 4 megabytes of program memory, 64 megabytes of 3D and texture memory, and 128 megabytes of memory for 2D characters and backgrounds.<ref>Template:Cite magazine</ref> The first title released for the system was Road's Edge, with Samurai Shodown 64 following soon after. Neither was particularly well received. The system was a failure<ref>Template:Cite web</ref> and by 1999 was discontinued, with only seven games released in total. SNK resumed releasing games on their older Neo Geo system.<ref>Template:Cite web</ref>

A home console version was rumored to be in production,<ref>Template:Cite magazine</ref> but was never confirmed by SNK.Template:Cn
