Kuka on kehittänyt Sega Dreamcast -konsolin?
As early as 1995, reports surfaced that Sega would collaborate with Lockheed Martin, The 3DO Company, Matsushita, or Alliance Semiconductor to create a new graphics processing unit, which conflicting accounts said would be used for a 64-bit "Saturn 2" or an add-on peripheral. Development of the Dreamcast was wholly unrelated to this rumored project. In light of the Saturn's poor market performance, Irimajiri decided to start looking outside of the company's internal hardware development division to create a new console. In 1997, Irimajiri enlisted the services of IBM's Tatsuo Yamamoto to lead an 11-man team to work on a secret hardware project in the United States, which was referred to as "Blackbelt". Accounts vary on how an internal team led by Hideki Sato also began development on Dreamcast hardware; one account specifies that Sega of Japan tasked both teams, while another suggests that Sato was bothered by Irimajiri's choice to begin development externally and chose to have his hardware team begin development. Sato and his group chose the Hitachi SH-4 processor architecture and the VideoLogic PowerVR2 graphics processor, manufactured by NEC, in the production of their mainboard. Initially known as "Whitebelt", this project was later codenamed "Dural", after the metallic female fighter from Sega's "Virtua Fighter" series.
