ok, my stupid idea of the day is...

How hard would it be to wire in a switch and an extra battery (9V). THe
switch would allow me to, in a game, switch between the 9v and the AA's that
are standard. Basically add a backup battery.

My question is, how would i wire that so that it doesnt drain on the 9v when
im not using it.
