To play your legal backup on an original Nintendo Wii console, you must use a softmodded system equipped with a homebrew USB loader.

Today, when you encounter a file named Super Mario Galaxy 2 -SB4E01-.wbfs , you are looking at a compressed backup of this masterpiece, formatted for use with custom Wii hardware or PC emulation.
