Hardware System files corrupted

[yabasi]

so I was playing a retail copy of a game and when i went back to the wii menu i get the "Systems files corrupted" message and i jsut reset. though i am still able to play backups of games and still have my save files on my wii o.o. So is there any problem with it and what caused this? O-o should i stop playing retail copies? i believe i have a wiikey v2 o.o
thnx.

Maybe a badly burned DVD at some point.

Doubt your wii `d have come back to life if ever`d have some corrupted system files, though.

DO A NAND BACKUP AS FAST AS YOU CAN, just to prevent a tragedy xD
