I haven't played any new Wii games for a while or updated my Wii. I tried to play MadWorld but was met by a blank screen (I have a PAL Wii), I researched and found that I need to install an IOS. I had no idea what an IOS is and my Wii is on 3.2E. There are all sorts of loaders and stuff now and I'm very confused and would like some guidance to get my Wii to run all the latest games and be on the latest version that supports homebrew. Thanks in advance .
