Ok does the game need the remotes to calibrate? or are the remotes not registering on the Wii and not working? I will give you answers to both problems.
Thanks for the help, but after I posted, we searched a lot of gaming sites where this problem was discussed. We tried a number of them, but the one that worked for us is below:
You need to open up the calibration and start the test. You won't be able to see where you are aiming, so to fix this, you have to use the "Home" button to guide the shots.
Assess where you need to aim and then pause the game using the Home button.
Position the cursor over the assessed target area and hit the Home button to return to the game.
Without moving the controller, hit the fire button. Another target will then appear. Do the same for that target to complete the test.
After completing this calibration, the aiming will work perfectly! (You have to do this for both HotD2 & HotD3.)
We had to do this once or twice to start for each remote, and everytime we restart the game, but it does work. It was the only thing we tried that did.
