Sensor bar problem

[nintendo13wii]

I want to play twillight princess(wii) in dolphin. but there are many in game actions that require sensor bar, such as shooting a target etc. so i want to ask few questions:-

1. can these tasks/actions be performed without using the sensor bar? maybe emulating sensor bar or using mouse cursor
2. if not then is there any way i can use my old wii sensor
3. or i should buy something called dolphinBar
