If you can string a sentence together and READ (an understand what you're reading) then Modmii CAN'T go wrong. The system menu will still be there, you can still play your retail games as normal but you will have the added bonus of having a USB loader if you wish. If you want the menu to look the same, simply choose no when Modmii asks you about installing DarkRedWii Theme. This app is tried and tested, probably thousnads of people have used it to mod their Wii
