No, don't upgrade to 4.2. Use the guide from here - http://www.wiihacks.com/recommended-...d-any-wii.html - and this will get your system to 4.1 and softmodded to play off a usb drive.
My Wii is version 3.2u and I have a WiiKey 2 Chip Clip installed. I also have updated to the most recent version of HomeBrew (previously installed with Twilight Hack about a year ago).
My big question is, "Should I upgrade to version 4.2?" I've read a lot of stories that I should and that I should not, but which is it and why?
My biggest goal is to softmod my wii to play backups off a usb drive. I'm tired of storing a ton of DVDs - some of which don't work well, like Mario Bros Brawl or other duel layer games.
My second biggest question is HOW? How should I go about upgrading safely (if that is the thing to do) and HOW do I set up to use a USB hard drive (Which loader should I use, can I get it on it's own channel, etc?
To tell the truth, since I installed homebrew on my 3.2U I kinda stopped paying attention to all the new mods, hacks, etc. Now, that my brother bought a new Wii (4.2u) I started looking into what I have to do to mod his system. WOW! There is a lot of new mods and other information. It's a bit of an overload. I think I can mod his system to have homebrew easily enough, and I think I have a good idea on how to add a USB loader on his system, too. But, when I was first hacking my system, the USB loaders weren't even an option. So, I am at a complete loss where to begin (or pickup and continue) on my wii.
Thanks to all that help.
P.S. Please, if you have instructions for me, make them clear step-by-step. Things like, "upgrade your IOS 60 and apply the most current channel patch." leaves me with more questions than answers.
4.2 will restrict your Wiikey2 to playing in region backups only. 4.2 only provided some anti-homebrew and anti-modchip changes and anything below 4.2 is 'better'.
3.2 is good, but a little old school. 4.1 is nice because you have the SD channel.
Not really doing much Wii stuff these days.
