The Sega Model 2 is an arcade system board released by Sega in 1993. Like the Model 1, it was developed in cooperation with Martin Marietta, and was a further advancement of the earlier Model 1 system. The most noticeable improvement was texture mapping, which enabled polygons to be painted with bitmap images, as opposed to the limited monotone flat shading that Model 1 supported.
Despite its high pricetag, the Model 2 platform was very successful. It featured some of the highest grossing arcade games of all time: Daytona USA, Virtua Fighter 2, Cyber Troopers Virtual-On, The House of the Dead, and Dead or Alive, to name a few.
Model 2 has four different varieties, commonly referred to as Model 2, Model 2A-CRX, Model 2B-CRX and Model 2C-CRX. While Model 2 and 2A-CRX use a custom DSP with internal code for the geometrizer, 2B-CRX and 2C-CRX use well documented DSPs and upload the geometrizer code at startup to the DSP. This, combined with the fact that some games were available for both 2A-CRX and 2B-CRX, led to the reverse engineering of the Model 2 and Model 2A-CRX DSPs.

Famous quotes containing the word model:
“She represents the unavowed aspiration of the male human being, his potential infidelity—and infidelity of a very special kind, which would lead him to the opposite of his wife, to the “woman of wax” whom he could model at will, make and unmake in any way he wished, even unto death.”
—Marguerite Duras (b. 1914)
