How many different NGCD models are there?
There are three versions, the front loader, the standard top loader and the CDZ. The front loader was the first NGCD model initially released in Japan, followed by the standard top loader that made its way to the US and Europe. In 1996, SNK released the CDZ, a revised top loading model with faster cache RAM to decrease load times. Like the standard top loader, the CDZ got released world-wide.
