Hello! I got a wii but it was already modded so Im not too sure about wat stuff was installed. The wii is a korean set with a us firmware of 3.2u, I have gamma backup launcher 003 on one of my channel. I have the homebrew channel. And I was told cios35.wad and cios36.wad were installed (dunno how to check for that.). Is it safe for me to just install the usbloader 1.5? I dont need to install/update any other cios? thanks!! Edit: forgot to mention, havent had any problem playing backup games on dvd on the set, but it wouldnt direct boot when I insert them. I have to launch them thru the backup channel. Dunno if this help or not.
