I have been out of the game for a long time so not sure on a few things.
I have a Japanese Wii that was bought in Dec 2006, it is fitted with a Wiikey 1. I haven't updated the Wii for at least 2 years (it's been in the cupboard for ages).
Can I update this via the system menu to the latest firmware (4.3) or will this affect the Wiikey and playing backups?
Can anyone give me any general tips?
