I'm sorry if I missed anything that shows the solution to this, but I've looked around for hours and I can't find anything on this. I had upgraded my Wii to System Menu 4.0 through official means and later found out that I needed an earlier version to use the Twilight Hack. However, yesterday I saw Bannerbomb and I was overjoyed. So I work my way through and install the homebrew launcher. My ultimate goal is to get a USB Loader working. For that, it seems I need a custom IOS installed. So I downloaded the Custom IOS38 rev13b installer (found here: http://gbatemp.net/index.php?download=6127). I follow the instructions but when I run the installer, I am unable to select IOS249. I think IOS256 or something similar is the closest that I can pick and that doesn't work at all. I greatly appreciation any help I can get. If you need any more information on my situation, just ask.
