Yo bro. What do you need help with? I would suggest a guide, but I need to know your firmware version. Check your Wii settings. Should 4.2U or something along those lines.
You doubt there's any? It's pretty simple if you google it, I doubt there's anyone who can actually write the firmware or figure out exploits (e.g. the Twilight method) on clraik, but wii modding is easy (last time I checked, circa 2008).
