Emulator

What's the problem?
Trying to play the "Pickup Game" in the menu "Basketball" of Wii Sports Resort, but when you want to throw the ball, button B of the real wiimote doesn't do anything.

Dolphin version with the problem (as it appears in the title bar, Ex.: "R
4779" or "R 6403M"):
from r5777 included (maybe r5776 too, but couldn't find a build to test it) every dolphin version has this problem.

(optional) Dolphin version that does not have the problem:
in r5775 the B button during the "Pickup Game" works perfectly!

Operating system and version:
32-bit or 64-bit:
WinXP SP3 32-bit

Game ID (as it appears in game properties, Ex.: "GZ2P01" or "RSBE01"):
RZTE01

Build command-line (not on Windows):

Was the ISO a plain dump from disc, compressed and/or scrubbed?
normal iso

Please provide any additional information below.
B button works in the menus and other resort games, but once you try to play the basketball Pickup Game from r5777(6?)on it doesn't respond anymore...
