Sorry if this question has been asked before..
I tried to play a backup of epic Mickey & my wii wants to do a system update.I am currently running system 4.2E & only play PAL games. Goldeneye works perfectly on my wii as it stands.
So is it safe to do the update as I dont want my backups to stop working..?
If not,how do I play Mickey without upgrading?
Thanks in advance for any help...
