When I went to the hack for Waluigi over king dedede, it led me to this
http://www.mediafire.com/?kqvjatjmq7g44mh. I clicked download and waited for it to open. It opened up adobe reader and said this-
"Adobe Reader could not open up 'Dedede-1.rar because it is either not a supported file or because the file has been damaged (for example, it was sent as an e-mail attachment and wasn't properly decoded."
If you know why this happened what I can do to solve it, please send me a message.
P.S. I don't have an SD card is it fine to use a USB?
Also do I need any specific channels on the wii like homebrew channel?
