Only normal Xbox games can be played on the original Xbox, original Xbox games can work on the Xbox 360 thought...
no but you can use xbox games on the 360
yes you can but you have to have a pro 360 or elite 360
yes all xbox360 controllers are the same but if you use just a xbox not a 360 then it will not work
no it has to be on an xbox360
no you cant use it on xbox 360 but you can on orignal xbox
Nope.
You need a internet connection on your Xbox to download games on the marketplace. You could use ethernet but you can also use wifi (wireless).
Simply remove the Elite hard drive from the Xbox360 Elite and insert it into the Xbox360's.
Yes, but not on every computer. You also need an Xbox 360 controller. Most Xbox games that I know have a PC version, so you wouldn't need to worry about the wrong system.
i think they use xbox360 or playstation3
id think so i know you cant use a cricket aircard on the xbox360 for xbox live
no because the original xbox does not have the wireless sensor need for xbox360 controllers.
