Hey there, it's UmbraWitchJeanne. You may know me from YouTube or DeviantArt. If not, well, that's okay too.
I've been using Dolphin since the past year or so, and I can easily say that it is a far better Wii emulator than Nintendo's official one for the Wii U. Not just because it actually upscales Wii games to HD (which the Wii U's Wii emulator can't do, for some reason), but because of the vast amount of features it has to offer, such as 60FPS hacks, texture hacks, etc.
I'll try to contribute to this wiki as much as I can.
