Issue 116 - android-bluez-ime - Wiimote not working Droid Bionic - A Bluetooth IME system for connecting gamepads to your Android - Google Project Hosting
Now I'm running leaked ICS on my bionic and it DOES finally work to connect in emulators also.
It sounds though like you're unable to get connection to wiimote at all though, exactly which app are you using? Three to try:
Wiimote Controller (I like this the best) - turn app on, press initialize and connect, and immediately after press 1+2 on wiimote
If you are on an official motorola ICS update, maybe they locked it down again somehow, but I'd think you'd still be able to connect with app, maybe just not in emulator.
