I did a few of these earlier, and got a "system files corrupt" error on one of them. So I had to unbrick through preloader/HBC/anytitledeleter.
It's not for me to say, but I advise you to get the emulators and maybe forwarder channels for them instead.
This is what one of them could look like.
The emulators are found on wiibrew.org
Forwarder channels are found on lots of forums, and on wadder.net
If not, you could try one of these links:
