I had a small idea: why not to make some points of options management as in emulator VisualBoy Advance? After all if there will be this option it will not be necessary to recustomize each time management for other games. An example: Call of Duty and Metroid Prime: Hunters. Has simply switched type of management and all. Or add possibility of preservation of configurations as in the emulator seag - gens. For each game there will be a file of configurations.
