Microsoft and NVIDIA reach deal for Xbox 360 backward compatibility

Microsoft has licensed some Nvidia tech for use in the Xbox 360 so that Microsoft can provide backwards compatibility for users to play (some) Xbox games. It's even been rumored that backwards compatibility wasn't even supposed to be a feature of the Xbox 360 but they decided at the last minute to throw it in there. It looks like it's been a big headache for them since it doesn't even seem like they have it down yet.
