so i just got a couple of black wiimotes - they could possibly be fakes but they seem legit - and they work absolutely fine except in metroid prime 3 they constantly beep. it basically sounds like a modem and it is faint but very irritating. it only seems to happen in MP3 thus far. i tested in several other games and it works perfect. both wiimotes do this with mp3, my original white ones don't. it's not a huge issue since i can just use white one for mp3, but i'm curious if anyone else has this issue or could test.
