Although, as you stated quite brilliantly, a clever individual could make use of a separate button and reuse one of the inputs already available. But, you know, a programmer type could maybe make it work without adding anymore external wiring/switches. There are games that you can still control with the controller after a game ends (think space invaders), but it's not like it has reason to HAVE to be that way. Hmmm.... something that could determine an end of game event and control a switch (I may say switch, whether or not the switch is a mechanical type or a transistor, but you know what I mean), that would switch the controller inputs to a different function.... Gonna have to think on that one...
