For quite a while I'd had my wii up and running, I'm not sure quite what happened as I didn't update my IOS's or alter anything, but about 6 months back, everything stopped working except retail disks. No wiiware, no gamecube backups, no wii backups. Nothing. I tried everything I knew how to do, reinstalling my IOS's, virginizing and re-bannerbombing, formatting my HDD and reinstalling every single game to my drive. But nothing, so eventually, after a couple months of fighting with it, I just gave up.
However, last night I found this site and noticed that the methods used were slightly different and contained newer versions of IOS's so I was like "Hey. What could it hurt?" After dusting off my Wii and giving these guides a go, I'm happy to say that last night I got wiiware to run, this morning I got GCN backups to run and this evening I got Wii backups running again and enjoyed some New Super Mario Bros. through CFG USB Loader. I want to thank all of the authors of the guides on this site for their hard work, you've saved me from spending money on a flatmii, another hdd, or just another wii altogether. Great work and very, very detailed as well! I can't thank you enough. :D
