A video game distribution network for use in airlines, trains, hotels, cruise ships, set top boxes, cable television systems, satellite and other wireless systems or other communications systems, distributes special purpose game binary image files to general purpose computing/display devices. Software emulators running on the general purpose computing/display devices model the game source platform and interpret and/or compile the game files to provide interactive video game play. Software emulators for emulating a handheld video game platform such as GAME BOY®, GAME BOY COLOR® and/or GAME BOY ADVANCE® on a low-capability target platform (e.g., a seat-back display for airline or train use, a personal digital assistant, a cell phone) may provide any number of features and optimizations to provide high quality graphics and sound that nearly duplicates the game playing experience on the native platform.

The invention provides numerous methods and devices for enhancing the use of gaming machines. Some embodiments of the invention provide enhanced functionality for legacy gaming machines. Alternative embodiments of the invention may be implemented in an entirely new gaming machine and/or in gaming machines that are not yet in existence. Some such implementations are directed to the use of non-native gaming software in gaming machines that include (a) different peripheral devices and/or (b) a different CPU from that of the gaming machine for which the gaming software was written. These implementations may use software emulation and hardware abstraction methods and devices.

A software simulation method and program storage device for software defect detection and obtaining insight into software code is disclosed, where simulation consists of executing target software program code for multiple input values and multiple code paths at the same time, thus achieving 100% coverage over inputs and paths without actually running the target software. This allows simulation to detect many defects that are missed by traditional testing tools. The simulation method runs a plurality of algorithms where a plurality of custom defined and pre-defined rules are verified in target software to find defects and obtain properties of the software code.

A simulacrum security device and methods. In one embodiment, a simulacrum or likeness of a physical security device is provided for use in conjunction with a software emulation of the security device. In one implementation, a “faux SIM card” is provided that does not contain Subscriber Identification Module (SIM) information itself, but instead enables a user to download Electronic SIM (eSIM) information (e.g., from a network or eSIM server) which is loaded into a software emulation of a Universal Integrated Circuit Card (UICC) device. The faux card is printed with an activation code, scan pattern, or other activation or access information. The subscriber purchases the faux card, and enters the activation code into a device; the entered activation code enables the device to log onto a network, and download the appropriate eSIM data. Delivery of eSIM information as enabled by the faux card addresses deficiencies in existing SIM distribution schemes, provides users with an enhanced perception of security, and further addresses various legal requirements.

Multiple versions of a runtime system, such as a software emulation application that emulates a legacy hardware architecture, are allowed to co-exist in the memory of a new hardware architecture. The operating system software of the new hardware architecture reads configuration data from a database or table to decide which version of the runtime system is desirable for an application program or game that is being loaded or is currently running, and, if a match is found, only that runtime system is invoked. To reduce storage footprint, the different versions of the runtime system may be stored using “differential patching” techniques. In this configuration, the operating system will always launch the same basic runtime system binary, but it will select a different differential patch to apply at run-time based on the title as determined during the database lookup. In this fashion, future changes to the runtime system to correct software bugs, incompatibility issues, and the like only need to be tested for the relevant target application programs or games.

Programs on a non-native platform are executed by executing plural programs in first and second software emulators. During execution of the programs at least one program monitors or controls at least one other program's threads or processes using an interface. A program on the platform is debugged by executing a debugging program on the first emulator and executing the program on the platform on the second emulator. The debugging program makes calls into the processes and threads of the program on the platform. The calls are transmitted from the first to the second emulator via an interface.

A data structure of readily accessible units of memory is provided as computer useable media having computer readable program code logic providing information tables and a software emulation program to enable hardware to run new software that uses transactional memory and a bit associated with a transaction for executing transactional memory constructs. The data structure with Guest PTRAN bit is used in emulation of software written for a given computer on a different computer which executes a different set of instructions. The emulating instructions are used to provide transactional memory instructions on a computer which does not support those instructions natively

A system and method is provided to improve software simulation. A software emulator is used in conjunction with a hardware simulator. A special snapshot instruction is included in the software code that is emulated. When the snapshot instruction is encountered, values such as register, memory, and program stack values, are stored creating an initial snapshot. Code continues to be emulated and, when the next snapshot instruction is encountered, the values are written to create a second snapshot. The initial values are used to set an initial state in a hardware model that is simulated on a hardware simulator. The results of the hardware simulation are compared to the second snapshot to uncover software errors and/or hardware errors so that the software can be modified or the hardware design can be modified. Multiple sets of snapshots can be taken to analyze multiple sections of the software program.

A system and method for implementing a software emulation environment is provided. In one example, a mobile application can interface with an emulation environment that can be used to test whether the mobile application includes malware that can compromise the security and integrity of an enterprise's computing infrastructure. When the mobile application issues a call for data, a device mimic module can intercept the call and determine if the call includes a call for one or more checkable artifacts that can reveal the existence of the emulation environment. If such a call for data occurs, the device mimic module can provide one or more spoofed checkable artifacts that have been recorded from a real-world mobile device. In this way, the existence of the emulation environment can be concealed so as to allow for a more thorough analysis of a mobile application for potential hidden malware.
