I purchased a halo 2 game online thinking it was for the XBox 360. It is for the original XBox. The "support.xbox.com" states that it is an original XBox game that should play on the XBox 360. It does not on my machine.
I made sure that Halo 2 is compatible = yes.
It is North American version = NTSC with the proper Microsoft Label.
I made sure my XBox has the latest (June 20, 2012) update.
The XBox sees the disk because the "home screen" shows "Play Halo 2".
When selected the screen goes blank and about 15 seconds later comes up with "unable to play game. Redownload game."
I have replaced the 20gb original hard drive with a 250GB 7200rpm drive and synced via transfer cable.
I make sure I am NOT signed into my profile on XBox LIve.
All my other games work just fine. Including the ones downloaded from the marketplace and reside only on the hard drive.
I only have the one original XBox game of Halo 2 so I cannot try a different original XBox game to see if that will work.
I am out of ideas. Please assist.
