Wii System Update 4.0
Feature additions on your Wii console when it is updated to version 4.0:

SD Memory Card Functionality

The SD Memory Card functionality of the Wii console has been enhanced to support the following features:

• An SD Card Menu has been added to the Wii Menu. This allows you to launch a Virtual Console game, WiiWare title or Wii Channel from an SD Memory Card (SD Card or SDHC Card).
• It is now possible to download games, titles and Channels directly to an SD Memory Card (SD Card or SDHC Card) from the Wii Shop Channel.
• The Wii Shop Channel and Photo Channel 1.1 now support the use of the high-capacity SDHC Memory Card format.

Please note that at the time the Wii System Update 4.0 was released, Nintendo made available an updated version of the Wii Speak Channel that supported the SDHC Memory Card format. However, the Wii Speak Channel is no longer available for download from the Wii Shop Channel, and it cannot be transferred to Wii U.

Wii Shop Channel

• The Wii Shop Channel now includes Virtual Console Arcade.

Important: Save files created by unauthorised modifications may cause damage to your Wii console. This Wii Menu update will detect and automatically delete such files. Please note that these deletion measures will not affect Wii consoles that contain only normal save files.

Wii System Update 3.1

Feature additions on your Wii console when it is updated to version 3.1:

You can now use a USB keyboard with your Wii. Please note that some USB keyboards may not function correctly. Nintendo recommends the Classic Keyboard 200 from Logitech.
