Gaming machines and systems having a universal interface layer linking a gaming platform to a hardware platform are disclosed. In particular, the universal interface layer is configured such that the gaming platform is hardware platform independent and such that the hardware platform is gaming platform independent. Platform independence can facilitate the interchangeability of one platform without a corresponding need to modify the other platform. The gaming platform can include various gaming modules and an operating system, while the universal interface layer can include firmware, various additional gaming modules, hardware specific drivers and various APIs to facilitate communication between the gaming platform and other universal interface layer components. A safe storage manager can be included to utilize a non-volatile storage component to store data regarding a gaming machine state, with the state being recoverable after a substantial interruption to the machine.
