Hey all, I'll cut right to the chase. Long story short, I finally decided to install the back-up launcher on my Wii. I got the custom cIOS (the one with the Sonic icon) all ready and I went to install it. All 15 parts downloaded but then I got some kind of error message and when I try to launch a game in the back-up launcher I get a error code telling me I have no IOS to run it. I currently have Wii version 3.3U. Do I need to downgrade in order to install the cIOS? How would I go about doing that? Also, would it be safe to upgrade back to 3.3U after the cIOS is installed? I only ask because my friend also has 3.3U and the back-up launcher, but he installed it prior to upgrading to to 3.3U. Any help you can give would be greatly appreciated! Thank you!
