Wii Play: Motion

Wii Play: Motion, known in Japan as Wii Remote Plus Variety (Wiiリモコンプラス バラエティ, Wii Rimokon Purasu Baraeti), is a party game for the Wii video game console and the sequel to the 2006 game Wii Play and a member of the Wii Game Series. All retail copies of Wii Play: Motion are bundled with a Wii Remote Plus controller. Like its predecessor, Wii Play: Motion is a minigame collection that features Miis as playable characters. Twelve minigames are available to play with both single-player and multiplayer modes. All the minigames require use of the Wii MotionPlus accessory, which allows Wii Remote movement to be detected with greater accuracy.

Wiimote Speaker
The Spooky Search mini game uses the Wiimote speaker as a radar, emiting bips to guide the player, but Wiimote speaker isn't emulated properly on Dolphin, making this mini game very hard or impossible to pass. Without clearing this mini game, you can't make any further progress on Wii Play Motion. Disabling "Alternate Wiimote Timing" on ISO properties and enabling DSP LLE partially fix this issue, you'll get crackling sound mixed with high noises on Wiimote speaker and the Wiimote itself will randomly disconnect.
