if you have dvdx installed, it can mount the dvd. using an ftp client on your computer, you can browse through the dvd and get the file
Can confirm you can do it this way. DVDx normal install will let me read backups in FTPii, DVDx PatchMii install lets me read my originals. I don't know the specifics on why, but that's how it works for me.
and my Wii-Fit didn't have MIOS8, I believe newer versions might though. Wii Music definitely has MIOS8
