1. I re-modded my Wii about a year or so ago with Modmii. After I followed the guide and installed everything, I noticed there was a channel on my system menu called USB loader channel with a grey-black background and a spinning USB hard drive icon. What exactly does this channel do? 2. I've been wanting to install some new channel wads to increase the usefulness of my Wii console. This isn't something I've ever done before (besides during the modmii guide) I'm not sure what sort of precautions to take to make sure I don't brick my wii. (I found a reputable source for wads so that shouldn't be an issue) I was not able to install bootmii as boot2 during my modding process so that is not a possible recovery option if I get a brick. Because of this I am very cautious and have not modified anything on the NAND since I modded. (I do have a NAND backup) What should I do to make sure my wads are safe to use, and that I am installing them properly? Thank you.
