Emulator

Try to use the alternate wiimote timing in game properties

It does not work. In the description noted that it is for real wiimote, not emulated.

Between 7271 and 7272 is something about changes in wiimote, maybe cause in that.

I can confirm the findings and that ra80429b02093 seems responsible. Emulated wiimote z shake doesn't work since that rev.(real wiimote works fine)

After some testing with reverting stuff none of the changes below are responsible:
/Data/Sys/totaldb.dsy
/Source/Core/Core/Src/ConfigManager.cpp
/Source/Core/Core/Src/ConfigManager.h
/Source/Core/Core/Src/HLE/HLE.cpp
/Source/Core/Core/Src/HLE/HLE_Misc.cpp
/Source/Core/Core/Src/HLE/HLE_Misc.h
/Source/Core/Core/Src/IPC_HLE/hci.h
/Source/Core/Core/Src/HW/WiimoteEmu/EmuSubroutines.cpp
/Source/Core/Core/Src/HW/WiimoteEmu/Speaker.cpp
/Source/Core/Core/Src/HW/WiimoteEmu/WiimoteEmu.h
/Source/Core/Core/Src/HW/WiimoteReal/IOWin.cpp

So what left is:
/Source/Core/DolphinWX/Src/ConfigMain.cpp
/Source/Core/DolphinWX/Src/ConfigMain.h
/Source/Core/Core/Src/Boot/Boot.cpp
/Source/Core/Core/Src/HW/WiimoteReal/WiimoteReal.cpp
/Source/Core/Core/Src/HW/WiimoteReal/WiimoteReal.h
/Source/Core/Core/Src/IPC_HLE/WII_IPC_HLE_Device_usb.cpp
/Source/Core/Core/Src/IPC_HLE/WII_IPC_HLE_Device_usb.h

One of the changes above seems to be responsible. I will try to track it further down if i can....

If real wiimote works fine, then it won't be in WiimoteReal.cpp.

That said, maybe the emulated shake needs to have it's values adjusted?

I can't track it down further since there are conflicts :-/, anyway hope it helps.

Renamed it a bit.

I have this same exact issue. I'm using my PS3 controller to play these games. Shake works in Mario Kart Wii and it works in New Super Mario Bros. But not in Wario Shake It.
