Well, if you know me from the SSBC then you know that my wii never accepts my brawl disk and the disk is perfect, but still take over 100 tries before it works. I though my wii was just retarted, and then I found this on the nintendo support page. It says how brawl doesn't work on some wiis and that they will fix it for free if you send it in. So I'm sending my wii in soon, wish me luck!

Update:

I sent it in already and got it back within a week. now brawl works flawlessly. Yay!!(although i suck now since i havn't played in so long...)
