I have a wireless sensor bar for my wii due to the cat chewing threw the cord of the one that came with the system. While playing NSMBW I turned the sensor bar off. I was still able to pull up with the controller and it did the jumpy spin you do when you pull your controller up. I'm wondering how much you can do without your sensor bar being turned on/hooked up.
You should be able to do everything that only relies on shaking/turning the controller, but not things that involve pointing the controller at anything. Without the sensor bar, the system will be able to tell how you move the controller, but not it's position relative to the TV.
The Wii-remote has three technologies that make it work.
Firstly it has an accelerometer which detects "acceleration". They put these things in digital cameras so when you take a portrait it knows that you took a portrait and they also have it in the iPhone. In a nutshell it detects tilting and waggle.
Then there is Wii Motion Plus which is a gyro. Basically it can figure out how much the remote has rotated from its origin so if you sit it on the table and spin it 90 degrees it will know that it has been spun about 90 degrees. Without it the Wii Remote would think "I moved but now I have stopped and up is still up".
Lastly it has an IR camera on the end of the remote which picks up the sensor bar. This works via line of sight so if you cover the end of the remote it will stop working. Also, if you point it out a window it will "think" its seeing a very, very shaky sensor bar. Because Wii Motion Plus uses this for orientation its really important with things like Swordplay on Resort that you close your curtains!
but yeah, if you are doing just buttons, tilt and waggle (like New SMB Wii) you don't need the sensor bar
