Every battery has a voltage curve though; even alkaline batteries will drop off the 1.5v region after some time. Comparatively, ni-mh rechargeables will hold 1.2v more consistently and for longer than an alkaline, where it's voltage drops pretty quickly as the battery dies.

If the game has native support for controllers, maybe the USB pack could act as a controller and you "mirror" the controller input between both the pack and the deck itself?
