Here is "Pimp My Wii", an homebrew that will install missing and outdated titles from your Wii console.The program will detect missing or outdated IOS and check that you have the latest version of the Wii System Menu. It also checks if you have the latest Wii Shop Channel.If you don't have the latest versions of those titles, the program will download them, or read them from USB or SD to install them. When using this program, you will have all advantages from 4.1 cumulated from those of 3.2, and this without drawbacks!
The homebrew is displayed automatically in english or french depending of your Wii's language. It is also compatible with NTSC-U, NTSC-J and PAL Wii consoles. (Korean Wii theoricaly compatibles but IOSes specific to this version will not be installed).
Warning: I do not take any responsibility for any damage in your wii because of a improper usage of this software.
