I've been getting this problem recently where the message "System files are corrupted" comes up when I power it on. I used to get it every once in a while randomly, but now its very common, I just tried 6 times in a row and its the same thing, it goes back eventually. I have not done any hacking recently when this started, I had the USB loader installed months ago it was the last thing I did and no problems. No recent updates installed from games or anything. My brother has been playing MH3 like a madman 8 hours a day on the Wii this past week. Since school is out, I don't know if hes just running it too much, I don't know why it would cause this message to come up, but its the only thing unusual going on my with my Wii recently. I only have bootmii installed as a super back up. Maybe I should install preloader too (so I can get into homebrew channel anytime right, this would let me get in and fix it even if I was getting this message). Anyone know what this is or gotten it before and know what to do?
