Hi! I like to show you a really easy instructable to how to run the Homebrew Channel which is actually called Homebrew Launcher on the Wii U.

You'll need:

Let's go!

Step 1: Prepare SD Card

You'll need to format your SD card, and the data on the card will be lost. If you want the data, back it up.

So, you'll need to format the SD card with the settings on the picture/these settings:

We are half ready with the SD card!

Step 2: Copying Files & Inserting the SD Card

Now, we'll need the Homebrew Launcher files from GitHub.

First, you'll need to download it from here.

Click on the first .zip file(not the webserver).

Next, copy the contents of the .zip file to the SD card.

And... we are done with the card!

Insert it into the Wii U, and power it on.

Launch the Internet Browser, and type in loadiine.ovh, and select the latest Homebrew Launcher on the dropdown list.

For the final move, press Submit, and wait.

After approx. 5 secs, you'll be on the loading screen of the Mii Maker, and then BOOM! You're in!
