Hello,
I just want to say that Borg8401 is correct about Dolphin not running in true fullscreen and also mention that there's a simple solution to this with the latest version(s) of Shadowplay. It is now possible to choose "Allow desktop capture" in the Shadowplay settings which will allow you to record footage from Dolphin just like any other game.
I only registered to post this reply since this was one of the first hits when googling for "Dolphin Shadowplay" :-)
