Dynamite Cop [Model 2C] ~ Sega Model 2 dynmcopc
2The Sega Model 2 is an arcade system board originally debuted by Sega in 1993 as a successor to the Sega Model 1 board. It is an extension of the Model 1 hardware, most notably introducing the concept of texture-mapped polygons, allowing for more realistic 3D graphics for its time.
Designed by Sega AM2's Yu Suzuki, he stated that the Model 2's texture mapping chip originated "from military equipment from Lockheed Martin, which was formerly General Electric Aerial & Space's textural mapping technology. It cost $2 million to use the chip. It was part of flight-simulation equipment that cost $32 million."
"I asked how much it would cost to buy just the chip and they came back with $2 million. And I had to take that chip and convert it for video game use, and make the technology available for the consumer at 5,000 yen ($50)" ($85 in 2017) per machine. He said "it was tough but we were able to make it for 5,000 yen. Nobody at Sega believed me when I said I wanted to purchase this technology for our games."
There were also issues working on the new CPU, the Intel i960-KB, which had just released in 1993. Suzuki stated that when working "on a brand new CPU, the debugger doesn't exist yet. The latest hardware doesn't work because it's full of bugs. And even if a debugger exists, the debugger itself is full of bugs. So, I had to debug the debugger. And of course with new hardware there's no library or system, so I had to create all of that, as well. It was a brutal cycle."
The Model 2 board was an important milestone for the arcade industry, and helped launch several key arcade franchises of the 1990s, including Daytona USA, Virtua Cop, Sega Rally Championship, Dead or Alive, Virtua Striker, Cyber Troopers Virtual-On and The House of the Dead.
Despite its high pricetag, the Model 2 platform was very successful, and in early 1996 Sega began licensing the board to its competitors. The Model 2 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,[citation needed] and Dead or Alive.
Model 2 has four different varieties: Model 2 (1993), Model 2A-CRX (1994), Model 2B-CRX (1994) and Model 2C-CRX (1996). 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.
