Yeah, the only time the batteries in the VMU are used is when the DC is off. When the DC is on, it gets it's power from the DC. So you don't need batteries in the VMU unless you plan on using it by itself, like playing a minigame. The only problem by not having batteries is the very annoying beep that the VMU emits when you turn the DC on.Quote: from Shaneus on 3:35 am on Oct. 4, 2001
took the batteries out... still operates exactly the same... ie. images appear during games etc.
