After a ton of reading, I might be more confused now than before. lol. I am trying to figure out how a banner brick happens. From what I read, it is due to a bad "banner" ie;wrong size, etc, and then corrupts the system menu. My questions: 1)When does the banner brick happen? When rebooting the Wii after installing the bad wad? Or can it happen anytime after? 2)If it can happen later, is it preventable by running from the SD in the new 4.0 feature? 3)Is there a way to tell if the Wad is safe/correct BEFORE I install it? Thanks!!
