20090055611 | REORGANIZING A WAGERING GAME MACHINE'S NVRAM - This document discusses, among other things, systems and methods for managing the contents of NVRAM in a wagering game machine. A method copies a first data of an NVRAM module to a storage device, wherein the NVRAM module is associated with a wagering game machine and then copies a second data to the NVRAM module. | 02-26-2009 |
20100048297 | ELECTRONIC GAMING MACHINE SECURITY FOR SOFTWARE STORED IN NONVOLATILE MEDIA - An illustrative method provides security of software resident on electronic gaming machines (EGMs) that permit wagering on games. A determination is made if all software files stored on a partition of a nonvolatile storage device resident in an EGM are authenticated image type files prior to any attempt to execute any of the software files. Further processing by the EGM of all of the software files is terminated upon the determination that one of the software files is not an authenticated image type file. | 02-25-2010 |
20100130287 | MANAGING SECURITY FOR NETWORK-BASED GAMING - This document discusses, among other things, systems and methods for managing security for network-based gaming. A method and system download and install an image of wagering game content on a wagering game machine, wherein the wagering game machine is capable of receiving a wager input from a player. The image is validated and may be transformed to a virtual storage device, such that it appears to be a physical storage device. The files may be accessed and validated in a similar manner as if they were stored on a physical storage device. In some cases, the same image format for content in an image is the same as if the content was stored on a physical storage device. | 05-27-2010 |
20100137058 | WAGERING GAME MACHINE PROVIDING A WRITE ONCE RUN ANYWHERE ENVIRONMENT - Systems and methods include determining a hardware configuration in accordance with the detection of the presence or absence of hardware modules on a wagering game machine. Various services are selected base on the hardware configuration, where the service selected provides an interface to a wagering game. The services provide an abstraction of various functions provided by various hardware platforms upon which the wagering game may execute, and take into account differences in the platforms. | 06-03-2010 |
20100248819 | NVRAM MANAGEMENT IN A WAGERING GAME MACHINE - Systems and methods are used to manage the contents of NVRAM in a wagering game machine. NVRAM may be pre-allocated for various purposes prior to loading a first wagering game on a the wagering game machine. A second wagering may be loaded on the wagering game machine. The second wagering game reuses the pre-allocated NVRAM portions for the same purposes as the first wagering game. | 09-30-2010 |
20100298043 | WAGERING GAME MACHINE UPGRADE AND ROLLBACK - Systems and methods provide for the selective backup and rollback of software, firmware and data components of a wagering game machine. | 11-25-2010 |
20120295693 | DYNAMIC SIGNATURE MANAGEMENT - Apparatus, systems, and methods may operate to determine at least one signature associated with a static image stored in a storage medium housed within a wagering game machine operable to present a wagering game. Additional activity may include repetitively generating a signature image comprising a sorted list of signatures, some of the signatures in the sorted list being hardware signatures associated with a corresponding plurality of hardware components physically attached to the wagering game machine. Additional apparatus, systems, and methods are disclosed. | 11-22-2012 |
20120329562 | WAGERING GAME MACHINE PROVIDING A WRITE ONCE RUN ANYWHERE ENVIRONMENT - Systems and methods include determining a hardware configuration in accordance with the detection of the presence or absence of hardware modules on a wagering game machine. Various services are selected base on the hardware configuration, where the service selected provides an interface to a wagering game. The services provide an abstraction of various functions provided by various hardware platforms upon which the wagering game may execute, and take into account differences in the platforms. | 12-27-2012 |
20140087863 | Electronic Gaming Machine Configuration using an Impromptu Configuration Channel - An electronic gaming machine (EGM) may use a temporary network to perform configuration updates upon determining that a maintenance mode is active and that normal gaming operation is suspended. The temporary network may use cryptographically paired wireless devices that prevent man-in-the-middle attacks or eavesdropping. Alternatively, the temporary network may use an existing network that is utilized during normal gaming operation for accessories and/or loyalty data. Once the temporary, or ad hoc, network is established, a host electronic gaming machine or a standalone device may be used as a repository from which configuration information may be propagated to other electronic gaming machines, even if the other electronic gaming machines have a different games or configurations from that of the host. This capability may be particularly helpful in jurisdictions where EGM networking is prohibited during game play operation. | 03-27-2014 |
20140094319 | METHOD FOR MULTI MACHINE CRITICAL MEMORY VERSIONING, MIGRATION AND REPLICATION - A notification that the data in the critical memory is to be accessed may be received. The data in the critical memory may be reviewed to determine if a version update is required. It may be determined if the data in the critical memory requires a version update. If the data requires a version update, a related version algorithm may be used to retrieve the data from the critical memory. | 04-03-2014 |
