PS2 controller not working on Wii games

[Averist]

Hello, this is my fisrt time using Dolphin Emu.
I have a PS2 to USB controller, it works fine playing GC games but nothing works when playing Wii games.
I can map the controller but it still not working. ie : in fatal frame 4 it said controller not connected

I have set the wiimote setting to Emulated Wiimote and use the Classic Extension.

This is my Wii Classic controller setup


And i leave the Wiimote controller mapping blank.


Should i mapped the wiimote 1st before i can use the Classic controller??

Can someone show me a proper wiimote setting & classic controller button mapping?
I have a X360 controller but the left analog is a bit broken so i use a PS2>USB controler.


Sorry for my bad english, im from indonesia
