Updating wii wiikey
A Wii System Update will add new features to upgrade your Wii console.
Click the blue arrow to access the Wii System Settings 2 menu.
Click "I accept" to install the latest system upgrade.
If you are running the Homebrew Channel or have modified your Wii in any way, you must be careful when installing system updates.
However, you may realize that, at times, you are better off running an old software version than upgrading to a new version with unseen problems.
In these cases, you may want to stop your Wii from receiving updates.
If you are running Wii firmware version 3.4, Nintendo can automatically update your system without your approval using the Wii Connect24 service.
