Instructions
Navigate to HackMii (see Resources) and click on "Download" to save the Homebrew Channel to your computer. Navigate to WiiBrew (see Resources) and pick Bannerbomb v1 or Bannerbomb v2 depending on your console version and save to your computer.
Format your SD card by going to "Start," "Computer," and right-click on your SD card. Scroll down and select "Format," and "Start."
Copy the downloaded Homebrew and Bannerbomb files into the "apps" on your SD card. Load any applications, emulators or other files that you may have into the "apps" folder as well.
Insert the SD card into your Wii once the files are copied correctly onto the SD card. The SD card slot on the Wii is in the front of the console. There is a small white cover you flip open to reveal the slot. Power your Wii on.
Navigate to the Wii memory menu, go to the SD card and open the SD card menu. Locate the Bannerbomb exploit and press A on your remote. Follow the on-screen instructions and you will have the Homebrew Channel installed.
Power off your Wii, and power it back on.
Go to the Homebrew Channel and open it by clicking on it and pressing "Start." Once the channel loads, your applications will also load and you'll have access to them. You have now successfully cracked your Wii without a mod chip.
