Modmii Instructions

[h=1]ModMii Wizard Usage[/h] You can use the ModMii Wizard to softmod any Wii. Even if the Wii is already softmodded you can update all your softmods (overwriting existing softmods) by telling ModMii that it is the first time you're modding your Wii, even though its not. You can also use this wizard to setup up a USB-Loader instead of having to later use the USB-Loader Setup Guide
[h=1]Abstinence Wizard[/h] This wizard allows you to enjoy many of the benefits of a softmodded Wii without installing any unofficial content (ie. should not void warranty).
[h=1]USB-Loader Setup Guide Usage[/h] Set up a USB-Loader to saveplay backups of your games tofrom an external hard drive.

[h=1]HackMii Solutions Usage[/h] Fix the Upside-Down Homebrew Channel and no Vulnerable IOS errors that sometimes occur when using the Hackmii Installer. You should only need thisfunction if you experience one of the errors due to an old softmod which was not performed by ModMii.
[h=1]sysCheck Updater[/h] You can supply ModMii with your unique sysCheck.csv log and ModMii will analyze it then notify you which specific softmods you're missing. It will download only the files required to update your softmod as well as build a custom guide for you to follow. You can analyze a log by dragging it onto ModMii.exe or a shortcut for it.
