Geekdoc,

Sorry, but there is no way to turn off the default action of the Home key without modifying one of the osso binaries that ships with the firmware, and you can't do that without having root access (besides needing to change the source code). So basically, the Home key isn't for application use. Perhaps you should use the the zoom in and zoom out buttons for buttons 1 and 2, respectively. The action button (in between the arrow buttons) could be used for both the start and coin buttons. The coin button would correspond to a short button press, and the start button would correspond to a long button press (i.e. the button is held down for longer). Alternatively, add a toolbar that can be enabled/disabled, and the toolbar would have buttons for start and coin. And, don't forget the fullscreen button, which you might want to use if your application is always in fullscreen mode. And there is also the menu button.
