Here guys, some tools to test your wiimote. It made me realize that problem is not in Dolphin, so you should also try them. http://wiimotelib.codeplex.com/ - To test wiimote response. (Keep it on to see if something goes rong or just freezes)
http://onakasuita.org/wii/index-e.html - that one will allow you to use wiimote like mouse. Use it and see if disconnects or stop response, or don't operate properly.
