Have had this problem for a while, and not sure what's best here.
Half the time, when the Wii is turned on, I get the error 'System Files are corrupted. Please refer to the Wii Operations Manual for help troubleshooting', right after hitting the A button on the health warning screen.
It has seemed to be happening more often lately, and I'm trying to decide what's best.
First, is there actually a fix for this besides erasing everything off of the system??
I have a ton of VC games that cost money, and don't want to lose all of that. Plus, you can't back up Smash Bros Brawl and Mario Kart (of all the games it had to be these 2...).
At this point, the most important thing is saving those VC games (all that money...). If possible, I would be fine with transferring all of that (along with the Brawl and Kart data if possible) over to my new Wii U in a few weeks, but, if I would do that, do you guys think it could cause issues for my Wii U then??

I'm sorry
