Updating wii system menu
If the hidden EULA channel isn't installed, it's impossible to accept it, and online features of some games won't work.
To fix this, perform an online update through System Settings or go to File = Change Disc and select the ISO of a game which has an update partition, then go to the Disc Channel to perform the update. The Wii Menu will initially appear without any channels, except for the Disc Channel.
The grid is customizable; users can move channels (except for the Disc Channel) amongst the menu's 47 customizable slots by pressing and holding the A and B button while hovering over the channel the user wants to move.
Dolphin does not include the Wii Menu by default, and it doesn't need it; it is able to launch games straight from the Dolphin GUI.
(December 19, 2006): Activated the functionality of the Forecast Channel, as data had not been sent to it before this point.A workaround was to create the title data directory manually on the NAND.Now that allows installing the channel properly, the channel will remain broken until reinstalled.This is because Dolphin doesn't come with channels preinstalled as the Wii does; it's up to the user to install them, using the same process that was used to install the Wii Menu.
The import handling in Dolphin's IOS HLE was broken until and caused channels not to install properly.Modifying your Wii's software will void your Wii system's warranty and can potentially damage your console if done incorrectly. You either did it wrong or downloaded the wrong files. If your Wii stays frozen and will not boot, it means your Wii has suffered an unrecoverable brick, which is very rare, but not impossible.
