Describe your system:

Describe the problem:
 Currently playing Zelda no Densetsu: Mujura no Kamen. I have run into a trouble with
feedback from my controller.
 My Wii Classic Controller Pro is mapped correctly (I have played through approximately
3/4 of the game with no issues). Suddenly, after finishing a dialogue in Ikana canyon
(composer brother Sharp after lifting his curse), Mupen64plus behaves as though it
is constantly receiving input from the joystick causing Link to walk forward in game.
I am using Wjoy 0.7.1 Wiimote driver for Mac OSX.
 I have tried the following methods to fix the problem to no avail:
    1. Restart Mupen64plus
    2. Restart Wjoy
    3. Restart Terminal
    4. Un-pair Wiimote via Bluetooth system preferences, then re-pair
    5. Restart computer

None of the above attempts have worked, I checked to see if it was dependent on that
particular save-state, the problem occurs now even for new games. For the time being
I'm a little stumped. I will keep fiddling with it to try and find a fix, but in the
meantime, if anyone has some experience fixing this issue I'm all ears.

[UPDATE]
So this is pretty odd...

I installed a second copy of Mupen64plus in a separate folder and started up the same
rom file: This fixed the problem temporarily (new game no longer has the issue described
above)! I then loaded up my save state and the problem immediately came back!

I find this interesting because it seems that something about that particular sequence
in the game breaks whatever Mupen64plus uses to communicate with the Bluetooth controller
drivers!

I'll work my way back to that point in the game and make a save BEFORE that cutscene,
and then I'll go through the cutscene with the rice video plugin to see if the same
thing occurs, I'll also try it without a controller to see if the same thing occurs.
So there should be an update a little later, or tomorrow depending on how fast I can
do this hahahahaha.

[UPDATE 2]
This is going to take longer than I thought, it's looking like this MIGHT actually
be due to some damage in the electrical contacts within the Wiimote itself (despite
it being brand new -_-), I need to run to the hardware store to pick up a triwing driver
so I can take apart the Wiimote and clean it with rubbing alcohol.

After further testing, it has become apparent that this is indeed a hardware issue,
not a software issue. 

Fixed
