The Namco System 22 is the successor to the Namco System 21 arcade system board co-designed with the assistance of graphics & simulation experts Evans & Sutherland. It was first released in 1993 with the game Ridge Racer. It was essentially a continuation of the System 21 hardware design, where the main CPU provides a scene description to a bank of Digital signal processor|DSP chips which perform all necessary 3-D computer graphics|3D calculations. Additional graphical improvements included texture mapping, Gouraud shading, Transparency (optics)|transparency effects, and depth cueing thanks to the Evans & Sutherland 'TR3' chip/chipset, which stands for: Texture Mapping, Real-Time,Real-Visual, Rendering System.[1]

A variant of the system, called the Super System 22, was released in 1995. The hardware was largely similar to the System 22, but with a slightly higher polygon rate and more special effects possible.[2]

Game List

Each game has a 2 or 3 digit letter code assigned to it. Then a number 1 or 2, Then a Rev. A/B/C/D which denotes the software revision. The 1 denotes a Japanese version. 2 denotes a World version. So far there are no other numbers used other than 1 or 2. For World versions, usually only the main program uses a '2', the rest of the ROM labels use the Japanese region code '1'. There is one exception so far. The World version of Alpine Racer 2, which uses a World version DATA ROM, and also one of the WAVE ROMs is a World version, but one Japanese WAVE ROM is also used.[3]
