Hello, I'm new to Wii hacking and right now I'm unsure of some things. My Wii system was 3,4E when I tried the Twilight hack. Everything went well including the installation of the Homebrew channel. But then I tried to install the Wad manager. It said I had to downgrade my wii. I installed some unknown wads (everything I can recall was ISO in their names). Then I accidentaly lost all my wads. So I don't know what is installed in my wii. WiiWare and VC games can be found easily but I don't remember what ISO wads I was installing. I plan installing the Backup launcher gamma. So my question is, it is okay to install the backup launcher (and some including ISO wads again) without uninstalling the old ones?
