Heres something suprising about the XBOX 360

2005-11-18 17:34:21
The Xbox 360 comes in two versions: the hard drive-less "core" system for $299 and the premium package for $399. But those who buy the lower-cost version are in for a surprise - they won't be able to play any of the Xbox games they already own.

???????????????????????????????

Which part of the hardware in the xbox360 controls the backward compatibility ???
