Abstract
A disclosed gaming machine provides methods and apparatus of verifying the authenticity of gaming software stored in and executed from RAM on the gaming machine. When presenting a game on the gaming machine, a master gaming controller may dynamically load gaming software applications into RAM and dynamically unload gaming software applications from RAM. The authenticity of the gaming software applications temporarily stored in RAM may be verified by using methods to compare it with certified gaming software stored on one or more local or remote file storage devices accessible to the master gaming controller on the gaming machine. The verification process may be used to satisfy gaming regulatory entities within various gaming jurisdictions that require certified gaming software to be operating on the gaming machine at all times as well as to prevent tampering with the gaming machine.
