Ok, I just picked up a dreamcast at an auction with several games and 3 controllers. When I turn it on, it wants me to put in the date and such. I guessing the internal battery is dead. Anyways, I plug in the controller and nothing happens. I tried all three in all four ports and nothing. I have never used a dreamcast as I was going to let my kids use it. Is there a way to figure out what is wrong? Do the controllers take batteries? Please help!!!
