Running Newer Super Mario Bros. Wii

First, open your "Wii Options".

In order to proceed, update your Wii to version 4.3. If you don't want to update, follow THIS guide instead.

Note down which letter appears after 4.3 - where the hand is pointing to in the picture - as you'll need it for LetterBomb!

If your console is fully updated, go into your "Internet" settings, and then to "Console Information". Write down the MAC Address.

Next, go HERE. Input your MAC address, select the System Menu version and fill in the Captcha. Make sure "Bundle the hackmii installer for me" is checked. Cut the red wire.

A zip file will begin downloading. Save it.

Plug in your SD card and locate a folder named "private". If it exists, rename it to "private_old". Then, unpack the zip file onto the root of your SD Card. Delete the .txt files, they're not needed.

(Make sure that the SD is formatted to FAT).
