Hyper NeoGeo 64 © 1997 SNK Corp.
Released in September 1997. 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 Spirits 64, which SNK announced would be the first game for the system. By mid-1997 test units were on display in Japan.
Seven games were released for this platform.
