Emulator

What's the problem?
I'm using emulated Wiimote. In one section of the game, it asks to Tilt the Wiimote backwards "toward yourself". Tilting back won't work. Shaking Z axis does produce the wanted output, but the character is supposed to move backwards continuously, and it only walks one step at a time as it is.
In another section, I'm supposed to move the Wiimote forward. No button produces the wanted output. Both problems make the game unplayable at a certain point.
