How to use Ocarina codes on Wii channels?

[Hyperstar96]

I have codes, but I don't know how to add the channels to Gecko OS. How do I do this? ???

You'll need the newest Gecko OS and Code Manager.

I know how to add codes. I asked how to add the channels to Gecko OS.

[REDSOXROX]

That wasn't what I meant.
The channels should already be there, just select load channel, you don't need to add anything.
That's why I thought you might need a newer Gecko OS version

Oh, I get what you mean. I read that I had to downgrade, but I don't want to. Do you have to downgrade (my version is 4.0U)? I don't want to, but I will if I can still play games off of an SD card...

[REDSOXROX]

Yeah, that would be the problem.
You can fix it and still be on 4.0,
follow Link's "downgrade instructions" here: http://wiird.l0nk.org/forum/index.php/topic,3296.msg33175.html#new

You can skip the last step of actually downgrading, everything will work fine.
