How many Wii remotes can be hooked up at once with the basic sensor bar? Can you use the Wii remotes on the Game Cube games? Do you need an adapter to hook up the old style controllers/wireless controllers? What does it mean when the cursor/mouse disappears on the screen when you are starting up a game? Sorry if these are redundate questions, I tried to find the answers. I'm a single mom of a 10 year old boy so I don't get a lot of time to research things.
