I have had a hacked wii for quite a while, and I have gotten pretty good at updating and fixing problems I run across, so I do not consider myself a newbie exactly. I use USBLoaderGX to manage my backups, but there are 2 words that I see a lot, but have never taken the time to learn what they are, NAND and EMUNAND. Could someone please explain what they are to me, or at least point me in the right direction?
