i shall still answer even though op is out of here failed to authorise a game generally means the backup has been trunctuated in most cases .

 

1. A copy of the game burnt either by truncating or overburning which can be installed on a storage device.
2. A copy of the game burnt using the burnermax payload tool.
3. A storage device to install the truncated or overburnt copy. This can be either your console or an external USB
