Hyper Neo Geo 64

(Redirected from Hyper Neo-Geo 64)

The Hyper Neo Geo 64 is an arcade system board created by SNK, and released in September 1997. As the successor of the popular 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.[1] Only seven games were produced, none of which proved particularly popular,[2] 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.[3]

History

edit

The system was first announced in late 1995, and planned for release in late 1996.[4] 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.[5] By mid-1997 test units were on display in Japan.[6]

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.[7] The first title released for the system was Road's Edge, with Samurai Shodown 64 and Fatal Fury: Wild Ambition following soon after. None were particularly well received. The system was a failure[8] and by 1999 was discontinued, with only seven games released in total. SNK resumed releasing games on their older Neo Geo system.[9]

Reportedly, SNK had been working on a successor hardware. This was reported in 2021 and dubbed SNK Millennium.[10][11]
