Neo Geo (MVS), it was the first and only SNK
hardware set capable of
rendering in
3D, conceived to bring SNK into the 3D era that had arisen during the mid-1990s.
The system never managed to match the huge success of the 16-bit Neo Geo. Only seven games were produced, none of which proved particularly popular, and only one of them, ''
Fatal Fury: Wild Ambition'', has been ported to home systems. A home console version was rumored to be in development but was never confirmed by SNK.
History
The system was first announced in late 1995, and planned for release in late 1996. 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
''Samurai Shodown 64'', known as in Japan, is a 3D fighting game produced by SNK for its Hyper Neo-Geo 64 system. It was SNK's first 3D fighting game. After having released four ''Samurai Shodown'' games on the Neo-Geo, SNK announced that th ...
'', which SNK announced would be the first game for the system. By mid-1997 test units were on display in Japan.
The system was released, only in arcade form, in September 1997, featuring a custom
64-bit RISC processor, 4

s of program memory, 64 megabytes of 3D and texture memory, and 128 megabytes of memory for 2D characters and backgrounds. 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 and by 1999 was discontinued, with only seven games released in total. SNK resumed releasing games on their older Neo Geo system.
