I was downloading a game in wup installer and suddenly it froze and I turn it off the console. That day I tried to see if I could possibly fix it but I couldn't so I disconnected everything from the wii uand left there for months and now I wanna fix it to play games from my childhood. I tried the av and hdmi but my last option was to put all 256 combinations for the gamepad to connect to the wii. I don't no what to do now. Please help me guys
