How do you play Xbox games on 360?

Answer 1

Here is the full list of backward compatible games-http://www.xbox.com:80/en-US/games/backwardcompatibilitygameslist.htm

To play any of them, you must either have your 360 updated by conecting it to the itnernet, or use an official Xbox Magazine Disc, which occasionaly comes with the Backwards compatible Compat discs. Or you can order a CD from Microsoft themselve (its free i believe), but i am not exactly show how..

Answer 2

You play original Xbox games the same way you play 360 games, however be aware that not all original Xbox games are supported.

Go to the Xbox website to check the list if your original game doesn't play
