This is kind of a noob question, which has probably been answered before but I'm not finding it at the moment. Do you need a bluray burner if you download a PS3 ISO? Or is it possible to unpack it and either FTP it over or put on USB device for copy to internal drive and use something like multiman to play it? Can anyone point me to the some basic instructions? This is not for PSN/package installs. Thanks in advance!
