Is there a way to make a backup copy of halo 2 on a dvdr and still play it on xbox live because i tried it twice and the game works fine but it wont sign in to xbl. when you try it just goes back to the main menu

To play a backup game you need your mod enabled yes?

If you sign onto live with your mod enabled you will get banned no?

For the most part yes, but that should be changing soon. Very recently, the samsung drive was hacked, allowing for the xbox to play modified firmware. It will just be a matter of time for the word to spread, and for average hackers to begin to do it.

not possible as of yet and when it is it wont be allowed to be talked about in a halo context... sorry
