What you will need:
-A computer with at least 4GB of empty space and a good Internet connection
-An SD card with at least 4GB of empty space
-A retail copy of the game New Super Mario Bros Wii
-Lots of patience
Step 1: Downloading the Hack
Step 2: Installing the Homebrew Channel (Part 1)
Next, go back to your computer and go here. Input your Wii's MAC address, select the System Menu version and fill in the Captcha. Be sure that the button labeled, "Bundle the hackmii installer for me" is checked. Cut the red wire. A .zip file will begin to download, save it.
Windows users can use an archiving tool like 7Zip or WinRar to unzip the LetterBomb file. Mac users have archiving utilities built in. Just double click on the .zip and it will extract. Once extracted, the .txt files in the newly created LetterBomb folder can be deleted, they are not needed for the hack.
Step 3: Installing the Homebrew Channel (Part 2)
Now, take the contents of the LetterBomb folder and place them in the SD card. This should only take a few seconds. Remember, only copy the contents of the LetterBomb folder, not the actual folder itself. Once the files have been copied to the SD card, you can delete the LetterBomb folder, it will not be used again in this tutorial.
Properly eject the SD card from your computer and place it into the SD slot in your Wii. Next, go to the Wii Message Board. Scroll a few pages back until you see a red envelope with a bomb shape inside and an SD icon hovering over it. Click on the icon. Scroll to the bottom of the message and click confirm. After about 10 seconds, a page that looks similar to image 9 should show up. It may take a minute or two for the "Press 1 to continue" to show up, but be patient. When it does, press 1. Next, press A to continue. On the next page, use the D-Pad and A to choose to install the Homebrew Channel. When the Homebrew Channel has finished installing, select "Exit" and go back to the Wii Menu. A new channel should have appeared in the next empty space on the Menu, that channel should be the Homebrew Channel.
Step 4: Setting Up Riivolution
You should already have downloaded Newer Super Mario Bros Wii from the site. In case you haven't, here's a link. As I said earlier, the download may take a few hours, so be patient. Now, extract NewerSMBW.zip. This process will take a few seconds. The extracted .zip should produce two folders. One should be called "NewerSMBW" and the other "riivolution". Move these two folders onto the root of the SD card. It will take a few minutes to copy the files. When completed, the SD card should have either 3 or 4 folders in it. The folders are "NewerSMBW" "riivolution" "apps" and "private". Please note, the "private" folder is not required.
Step 5: Launching the Game
Step 6: Just a Quick Note
Newer Super Mario Bros Wii was made by a non-profit group that just wanted to make a hack of the original game for fun. I do not own LetterBomb, Riivolution, or Newer Super Mario Bros Wii. I'm just trying to help people out.
