Abstract: An open architecture for gaming machines that includes a gaming subsyst em implemented as an add-on card which enables the hardware functionality of a gaming machine to be implemented on a general purpose or industrial computer platform. In one embodiment, the add-on card is compatible with a standard bus interface, suc h as a peripheral component interconnect (PCI) bus interface. As such, gaming machi ne upgrades are greatly facilitated relative to current technology. In accordance with another aspect of the invention an add-on card is provided that can be connected to a general purpose or industrial computer to form a gaming machine simulator to enable third party software developers to develop game software for gaming machines without an actual gaming machine.

Abstract: A disclosed gaming machine has a plurality of "gaming peripherals," eac h communicating with a master gaming controller via a standard peripheral interface such as the USB (Universal Serial Bus). Further, the gaming peripherals empl oy a standard peripheral controller and one or more specialized "peripheral devices" (e.g., the actual lights, bill validators, ticket printers, etc. that perform the specific functions of the gaming peripherals). Much of the hardware associated with the peripheral controller is identical from one gaming peripheral to the next. Only a porti on of the peripheral controller hardware is specific to the different types of gaming peripherals.

Abstract: A system for authenticating software is disclosed. In one embodiment, the invention is utilized in conjunction with a gaming machine to authenticate the software utilized by the gaming machine or loaded onto the gaming machine. To achieve authentication, one exemplary mode of operation is used to authenticate the contents of a removable media, the removable media being used to perform any desired operation on the gaming machine. Use of a removable media provides means to store large amounts of software on a single media to thereby access and perform numerous tasks including software install, software update, diagnosis, authentication, or configure. Prior to use of the removable media in the gaming machine, an authentication file is created. The authentication file contains a listing of each file on the removable media and an associated hash value calculated with a known hash function. These hash values are calculated and stored in an authentication file when the files on the removable media are known to be trusted. Encryption of the one or more hash values may occur. At a later date when the removable media is used in the gaming machine, a hash value re-calculation is performed on each file to determine the hash value at the time of use. The re-calculated hash values are compared to the decrypted hash values stored in the authentication file on the removable media on a file-by-file basis. If the values match, the removable media authenticates. If the values do not match, the removable media does not authenticate.

Abstract: A disclosed gaming machine provides a gaming machine with a non-volatil e memory storage device and gaming software that allows the dynamic allocation and de-allocation of memory locations in a non-volatile memory. The non-volatile memory storage devices interface to an industry standard peripheral componen t interface (PCI) bus commonly used in the computer industry allowing communication between a master gaming controller the non-volatile memory. The master gamin g controller executes software for a non-volatile memory allocation system tha t enables the dynamic allocation and de-allocation of non-volatile memory locations. I n addition, the non-volatile memory allocation system enables a non-volatile memory file system. With the non-volatile memory file system, critical data stored in the non- volatile memory may be accessed and modified using operating system utilitie s such as word processors, graphic utilities and compression utilities.
