I'm sorry if this has been asked before, but I hope you understand that it's difficult to read through 125 pages of posts.
I'm running 3.3U (not sure which version...), I have the Homebrew Channel installed (v1.0.1). I have a D2PRO9 installed, but I recently discovered the USB Loader (as in, yesterday) and found out that many games run significantly smoother off of a hard drive. I was considering installing the preloader, both for brick-protection and for the simple feature of booting to the Homebrew channel first, since I'll be using the USB Loader primarily. I had two questions about it. First, with the latest version (.29) do I need to downgrade my Wii before I install it? Second, if I do, how do I go about doing that? Last, if I wanted to reverse the changes, how would I go about that, and would all my settings and IOS installations (I think I only installed 55 and the latest 36) be preserved?
An unrelated question, is Waninkoko's 4.0 safe to install? (Edit: I know this was asked, but I didn't see an answer)
Thanks in advance.
