I just installed the Backup Launcher on my Wii v3.3E. It works as expected but I have a few questions: 1. If my Wii dies will Nintendo still fix if they see the Backup Launcher loaded? Anyone ever had problems with that situation? 2. Is there a point in upgrading to the latest 3.4 system update or even downgrading? Will my backup launcher stop working if its upgraded to 3.4? Are there any games that require or auto install 3.4? 3. Is there a recommended method for installing DVD movie support? 4. Most of the guides mention IOS16, 248, 247, 249. What are those?
