? what are you on about reaperofwar7 ?
not "every" xbox game is playable on the 360 - but check out on the offical 360 website, it has a list of old games you can play on the 360 - unfortunatley, this is mainly done via internet updates through the 360, if you dont have a connection, then you have to do it via CD, which i havent done before, but cant see why that wouldnt work.
I played BLACK - that cool shooter from EA, the guys who made burnout on my 360, and it worked a treat!
however, i dont know about the "elite" 360 version, althought if the elite doesnt let you play old xbox games, then how on earth is it elite!
anyways, check their website, and search something along the lines of "backwards compatablity" - and youll find a nice list of old games you can play.
