I just found out about all this Wii stuff and this site ROCKS!
I am getting a little confused determining what I need to install and what I have already installed.....

I am on version 3.4 U
I have installed Twilight Hack
Then installed Home Brew
Then installed USB Loader GX - Totally ROCKS!!!

I didn't pay attention to what IOs etc I installed at the beginning...I just followed instructions. Everything works great.

How can I tell what I have installed so far?

Thanks!
