You can use dolphin emulator on PC with any controller connected. But on the wii, wii mote designed games better to be played using wii mote. It can save you a lot of headaches. From my own experience.... wii mote uses different sort of controls in different ways shake/ gyroscope sensor/ pointer/. For example, in kirby game shake was required to enhance inhale to move heavy barrier and I couldn't proceed. And also in "sakura wars so long my love" there was a scene where you asked to point using wii mote and I couldn't proceed because I was on wii u gamepad which only emulates classic controller.
