How to Install 2.2U on a Nintendo Wii

As of January 2011, the Wii system menu is version 4.3. The system menu needs to be updated for normal Wiis to be able to access the Shop Channel and play certain games. If you are looking into hacking your Wii to be able to play homebrew games or run homebrew applications, you will want to use an earlier release of the system menu. Version 2.2U is an old system menu version for the U.S. that is easy to install on your Wii as long as you have an SD card and some specific files.

Things You'll Need

SD Card
Soft modded Wii

Instructions

Download the Software

  Format your SD card to FAT32 if it's a new card. When you put in a new SD card it should give you formatting options. If not, select "Computer," and right-click your SD card choosing the "Format" option. Select FAT for file system and 32 for allocation unit size.
  
  If your Wii is already soft modded, your SD card should already be properly formatted and have files on it already.

  Download the firmware downgrade program (see Resources).
