I got this Super Famicom from the forum member DARK ANDY recently, and he said it had a minor graphical problem. When I got it today, it had an NES AC adapter with it. Is this safe to use, and could it be the cause of the prescribed problem?
(BTW, I checked vidgame.net already and it didn't help much... if the webmaster is reading this, you should know that the picture you have for a SFC exercise bike actually has a Famicom in the picture.)
