Dolphin 5.0 pointer mouse?

[Anbar48]

Hello, so I'm using a version of Dolphin 5.0 made portable (by the dudes at PortableApps.com), and I   recently started playing Super Mario Galaxy. So, I have a huge amount of trouble getting the IR pointer to go where i want. I tried setting the controller vales i.e., Up: Axis Y-, Down, Axis Y+, and when i move the mouse it snaps back to the center of the screen. Is there any way to make this work better?
