My Wii hasn't been used in a while, and I haven't really been paying attention to the homebrew scene much lately, so please be easy on me. I have a Wii with firmware 3.1U and a WiiKey v1 with 1.9s installed on it. I installed the HBC and am able to use WAD Manager to install WADs. The majority of them, however, spit out "this channel cannot be used" and refuse to work. I assume I need to upgrade to a newer firmware, but I've heard some bad things about 3.4. Can/should I upgrade manually to another firmware besides 3.4? I don't want to give up the ability to install WADs and such. Thanks all.
