ABSTRACT:
A method and device implementing a downloadable operatively connected to a plurality of gaming machines either by a direct communications link or through the use of one or more site controllers or PCs. Each gaming machine and site controller or PC contains two executable spaces, one of which typically contains the software image currently being implemented by the device. The other executable space is designated to receive from the central system a new software image that will be utilized by the device. The central system transfers a new image to be executed, via packet encrypted communications, to a networked device which stores the image in an executable space, while continuing to run the currently designated image. Upon instruction from the central system, the device switches over to the new image, allowing one or more machines to implement a software upgrade on a continuous basis.
