Ok, this is how to add The Homebrew channel onto an unmodded Nintendo Wii.
What you need is:
One Copy Of The Legend Of Zelda Twilight Princess With Save Data (Although this will be
lost. Save it to another SD card if you want to save the data.)
An SD Card.
An SD Card Reader for the computer
WinZip
Ok, the first step is to Download the Twilight Hack, this is basically the safest and
easiest way to add it to the wii.

The link above is the download for the twilight hack.
Once it is done downloading, unzip it. You will find three different Files.
It is the hack but for three different regions.
Copy and paste the hack for your region onto the SD card.
Now take out the Twilight Princess CD, Flip it over to the side WITHOUT The picture of
Link on it.
Look at the And Look at the Inner Circle of the CD, And look at the serial, depending on
what it is, you must use a different save. If you have the Japanese or European/Australia
version, just use the only save there. But for the American version, there are three
different codes.
America (USA) RVL-RZDE-0A-0 JPN  TwilightHack0
America (USA) RVL-RZDE-0A-0 USA  TwilightHack0
America (USA) RVL-RZDE-0A-2 USA  TwilightHack2
The files are in /private/wii/title/rzde/data.bin
Ok, now that that was taken care of, now its time to put it on to the wii.
Step 1: Start by making sure the SD format was FAT, If it isn't that format. Then change
the form to FAT. http://www.sdcard.org/about/downloads/
Step two: Copy the Private Folder From the download to the SD card.
Step three: Take the Elf or Dol file from the download and add it to the SD card
directory, and name it Boot.elf or Boot.dol if its either an elf or dol file.
Opps, I Accidentally pressed submit... xDDDD
Ok, now I Messed up, The SD Formater is for formating it if you get a message saying
Failed to read boot.elf (-1)!
Then you use the formater.

(This will delete all files.)
Now when all this is finished, take the SD card and insert it into the wii.
Turn it on, and go to the wii menu and select Wii Options, then Data Management, Then Save
Data, Then Wii.
Find your Zelda save, and delete it.
Then go to the SD card in it. And copy The Twilight hack for your region to the wii.
now insert the game, and start it up.
In Part one I Put what save you should use.
So select the one that you are supposed to use, if you select the wrong one don't worry.
It will make a noise but, It won't hurt the wii.
So once you choose the right one, turn around and run, or talk to the guy.
Enjoy!
