I had plenty of trouble with this, trying to get it to work I eventually cause almost all of my Homebrew Channels Apps to stop working. Managed to recover, back to the point I was at before trying this out. I haven't decided yet if I'm going to take another crack at it.
A question, I haven't touched the Wii Backup Loader, and don't really plan too, I don't really have any Wii games I'm worried about backing up. I do have several Gamecube games that I'd like backup copies of though which is why I eventually decided to try getting this running. So the question is -- if I have a patched MIOS that allows DVD reading, do I need DVDx as well (or another method of allowing for DVD reading?) If all I want to use DVDs for is the Gamecube backup launcher, is the MIOS enough?
