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, emitting bips to guide the player. Wiimote speaker isn't emulated properly, you'll get crackling and delayed sound, sometimes mixed with high noises and causing the Wiimote itself to randomly disconnect (influenced directly by the bluetooth adapter/stack). As result, this mini game is almost impossible to pass and you can't make any further progress on Wii Play Motion. A workaround is using or newer with Hybrid Wiimote option, making the Wiimote Speaker sounds be redirected to the system speakers.
