I'm a little new to Dolphin, I downloaded it to play around on my PC the games that I already own. I have both a Wii, and several games (I own all of the ones that I have a copy of). I have not figured out the whole NAND thing yet. Hell, I'm not sure if I even know what that is. However, I have been able to play Super Mario Bros (Which, once again, I own) on Dolphin without a Nand. On the other hand, when I try Brawl, it says something about a nand dump in the menu screen when I press "Continue without saving."
Why do some require it and some dont?
