Everything you need is part of the standard Android SDK directional pad support, start/select buttons shoulder pad buttons and joystick support
An existing game can be switched to use the physical buttons with minimal work... This isn't a rewrite, more like connecting another source event to the functions that handle user interactions. I expect most games to need less than a couple of hours of work to support this device.
