In response to criticism of the Neo Geo CD's long load times, SNK planned to produce a model with a double speed CD-ROM drive for North America, compared to the single speed drive of the Japanese and European models. The Neo Geo CD had met with limited success due to it being plagued with slow loading times that could vary from 30 to 60 seconds between loads, depending on the game. The CDZ was released on Decem as the Japanese market replacement for SNK's previous efforts (the 'front loader' and the 'top loader'). The front-loading version is the original console design, with the top-loading version having been developed shortly before the Neo Geo CD launch as a scaled-down, cheaper alternative model. The Neo Geo CDZ, an upgraded, faster-loading version, released in Japan only.A top-loading version, marketed worldwide, as the most common model.A front-loading version, only distributed in Japan, with 25,000 total units built.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 system is also capable of reading Redbook standard Compact Disc audio. Co-Processor: Zilog Z80 running at 4 MHz.This is essentially a Motorola 68000 clone. The most common CPU is the TMP68HC000 manufactured by Toshiba. Although the 68000 CPU was designed by Motorola, there were many other clones of this CPU found in the Neo Geo hardware.Main Processor: Motorola 68000 running at 12 MHz.The King of Fighters '96 Neo Collection.While the Neo Geo CD library consists primarily of ports ofВ MVSВ and AES titles, there are a few MVS arcade games which were not officially released for the Neo Geo AES and ported instead to the Neo Geo CD.ДЄ few games which were unreleased in MVS and AES formats were also released exclusively for the Neo Geo CD. Today, they can be found sporadically on the internet, especially through auction sites such as eBay. However its lack of a 'region lock-out' feature and the fact that it could play games from other regions made it a popular import item for enthusiasts in Europe and North America. Like the original front-loading model Neo Geo CD system, the CDZ was officially sold only in Japan during its production. The CDZ console was the third of three generations of the Neo Geo CD system offered by SNK, the first two being the 'front-loader' CD system and the 'top-loader' CD system. This was a result of a lack of ventilation in the cramped housing of the smaller unit and more heat generated by the newer drive, which could damage the circuit board. The console had a design flaw that sometimes caused it to overheat after certain periods of time, breaking the console in the process and making it hard to repair. Though the CD-ROM motor in the CDZ may have been more efficient than the one in the original, it was still a 1x speed CD-Rom. The truth of the matter, is that the CDZ had a larger cache. Popular rumor suggests that SNK made several changes to the CD hardware to end up with the CDZ, most prominent is the rumor that they increased the CD-ROM drive speed from 1x to 2x. Although SNK's American home entertainment division quickly acknowledged that the system simply wasn't capable of competing with 3D-capable powerhouse systems of the day like the Sega Saturn and Sony PlayStation, SNK corporate of Japan felt they could continue to maintain profitable sales in the Japanese home market by shortening the previous system's load-times. The Neo Geo CD had met with limited success because it was plagued by slow loading times that could vary from 30 to 60 seconds between levels, depending on the game. The Neo Geo CDZ was released in 1996 as the Japanese market replacement for the Neo Geo CD. The Neo Geo CDZ, a redesigned version of the console featuring a faster 2x CD drive.A 'top-loading' version that was marketed worldwide (the most common model).A 'front-loading' version (only distributed in Japan, 25,000 total units were manufactured).Three versions of the Neo Geo CD have been released:
