No, its a totally different format.
it plays some old xbox games
All of the Xbox 360s may play games. They are priced differently because of either memory space or package deals.
You can play some Xbox games on the 360 but on April 14th Microsoft will be ending that feature for Xbox live but you will still be able to play them off line. go to Xbox.com to find the list of games that you can play.
No.
You can not play xbox games on a playstation 2
no
Probably not
The Xbox is not designed to play PlayStation 2 games. A serious modification would be required to accomplish this feat, however, with the use of an Emulator one could play a PlayStation 1 game on an Xbox, but the legality of this is very questionable.
Of course not, are you stupid?
Hell naw
Yes. All original Xbox games are compatible with the Xbox 360. However, you cannot play an Xbox 360 game on an original Xbox, or course.
it is simple impossible Games are not converted they are designed to be exclusively used for the system they are designed for. A console or PC would have too be changed to play a game with an emulator program, not that you could run one on a Xbox to play games for a Playstation, but a PC could run different emulator programs that would let it play Playstation and Xbox games.
