Three versions of the Neo Geo CD were released:
SNK planned to release Neo Geo CD versions of every Neo Geo game still in the arcades. The console uses the same CPU set-up as the arcade and cartridge-based Neo Geo systems, facilitating conversions. The Neo Geo CD was first unveiled at the 1994 Tokyo Toy Show. The CDZ was only released in Japan and featured faster CD loading than the previous models.
