ok thanks
I installed the cios
but I still get the error.
this is obviously because I'm using dvd-rw and can't change the booktype.
although I'm still not sure if my wii is to new to play backups.
I'll get a dvd-r later to find out
I also tried to backup my nand and no, the file was still not on my sd card
so i tried it on a different sd card and it backed up correctly, however the key file isn't there.
am I doing it right?
