I don't know a whole lot about using the Wii, aside from playing it, but the other day while playing super mario bros, my Wii froze. I thought nothing of it and restarted it, but since then, it is unable to load past the health and safety warning screen. It doesn't tell me to press "A" to continue as it usually does. After restarting it multiple times, the press a message did appear once or twice, but once I press A, it goes to a black screen and won't load. Please help me !
