Abstract
A device for controlling electronic gaming machines comprises a single board computer (SBC) having a microprocessor, memory means, storage means and a ROM (Read Only Memory). The ROM includes: a loader program; verification program; an authentication program; and a presentation program. Additional Mass storage media in communication with the SBC store pre-verified and approved gaming software (program files) and related data files, each of which have a verification signature appended to them. Prior to usage of the gaming software, the program file software or data file is retrieved by the loader program and checked by the verification program which compares the verification signature with a newly calculated verification signature. If the newly calculated signature matches the verification signature, the requested file is deemed to be intact (a validated image).
