Am aflat de curand ca exista asa ceva. Citat din Wikipedia:
"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, but the Chihiro has a different MCPX chip with unique bootloader keys. The main system memory, at 128 MB, is twice that of a retail Xbox. In addition to this memory, the Chihiro also has additional RAM used for media storage - this was initially 512 MB but is upgradable to 1 GB. When the system is booted, the required files are copied from the GD-ROM to the RAM on the media board.
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, there are a number of challenges - the first being that the half-size main memory restricts the size of your working set and the second being that fetching assets from Xbox DVD drive is orders of magnitude slower than fetching them from the 512MB/1GB of RAM on the media board. These challenges are not insurmountable, though - for example, the Xbox release of OutRun 2 was able to retain the look and feel of the original arcade version."
