Abstract
Novel wager gaming systems, machines, and methods for ensuring that wager game code on a game disc executes on an authorized wager gaming machine are described. To prevent an unauthorized copy of a wager game disc or other storage medium is not able to execute on a gaming machine, the machine checks whether an authorization code has been previously written to the disc. If the disc does not have a code, the gaming machine generates a first segment of an authorization code which is used, along with other data, by a game provider to generate a final authorization code. This is done after the game provider verifies that the machine operator has permission, such as a license, to execute that game code contained on that specific disc. The final authorization code is transmitted to the gaming machine, equipped with a writeable optical disc drive, where it is written or “burned” onto the game disc. At this stage the game disc is tied to or associated with the gaming machine and can execute on that machine.
