List of Sega Arcade System Boards - Sega Chihiro

The Sega Chihiro system is a Sega arcade system board based on the architecture of the Xbox. The 733 MHz Intel Pentium III CPU and the Nvidia XChip graphics processor are common to both. Unlike the Xbox, Chihiro can support up to 512MB RAM through add-in memory modules. Chihiro games are distributed on Sega GD-ROM media, instead of standard DVD-ROM used by the Xbox.

Because the Chihiro and Xbox share the same hardware architecture, porting from the Chihiro is theoretically easier than porting from a different arcade platform. In practice, the much smaller memory capacity of the Xbox (64MB), presents a formidable challenge for home conversions of arcade titles which use Chihiro's larger memory configuration, however the Xbox release of OutRun 2 was able to retain the look and feel of the original 512 MB arcade version.
