Pimp my Wii 1.3.2
This program rules. The easiest way to trucha sign ios, gain nand access (to install cIOS), and upgrade all your IOS at the same time. I included all the IOS that you need if you do not have an internet connection. If you do have an internet connection you can also upgrade your system menu to 4.1 install the newest shop channel and the newest mios. Thanks to the creators!
Just click run the test and fix problems, say yes to all the ios updates and you are good to go.
