So if I update my Wii on the 3.2 firmware to 4.0 using Waninkoko's 4.0 uploader, what will I be able to do that I wouldn't be able to do if I used the Nintendo server's to update? Will I be able to install Wads, cIOS's, and still be able to using the Backup loader Gamma? Also, do I need to install the cIOS rev 8 with it? And what the hell does a cIOS do anyway?
