Wii Menu version 4.1 is now available for your Wii console. To update your Wii Menu to the latest version, please select the Update button at the bottom of the screen or select the System Update option in Wii System Settings.
This update provides behind-the-scenes fixes that will not affect features but will improve the overall system performance.
Because unauthorized modifications to save files may impair game play or the Wii console, updating to Wii Menu version 4.1 will also check for and automatically remove such save files.
**Please note:
If you've updated your Wii Menu after 7/15/09, you may not need to update again.
Thank you for updating your Wii console!
