Things You'll Need
Instructions
Download and install a copy of a respected Xbox emulator like the Xeon or Cxbx emulator.
Reboot your computer and insert the Xbox game you'd like to play into your computer's disc drive.
Dismiss any Autoplay dialog that appears and open a session of your new emulator program.
Click the "File" menu and choose "Open" from the options.
Find the drive your game disc is in and select it. Click "OK", and your emulator will run the game disc as if it were in an Xbox.
