Ok, all my tech nerds. I just got a used Dreamcast. It has power. It has sound, like I can hear the start up music. But there is no video. Any idea's? I am hoping for an easy solution cause I am not tech savy. But I bought this in hopes of putting a GDEMU in it. I don't suppose there is any chance of by putting a GDEMU in it the video comes back, huh? Help me out y'all.
