After downloading the older nes games, when I turn on the game, the picture is kinda of "flashy". I can't play the game becaus of it. I use an HDTV for it and can't figure out why. I have also hooked up our old Super nes 64 and playstation one, and all the game do the same thing. The Wii and Gamecube plays just fine. Does anyone know why this happens and what can be done?
