4.0.2 x64 Problema wii motion plus "WII SPORT RESORT"

[netsonic]

I'm sure that I had used my real wiimote with motion plus(build-in) to play WII SPORT RESORT in dolphin 4.0.X successfully several days ago, but now when in game the game asks me to add the motion plus on. However, I can play this game or other motion plus needed games (e.g. Wii Play Motion) in dolphin 3.5.x without any problem. I don't know why, dose my real wiimote have some problem or the emulator above 4.0 have some problem? If my real wiimote has problem, why can I play with dolphin 3.5.x ? if the emulators above 4.0 have problem, why had I played with them several day ago? This is really strange!
