Sensor bar

[linkmaster811]

Does anybody know of a way or any apps that emulate a sensor bar onto my screen so i dont need to get a physical one?

This is not possible. You can only simulate a sensor bar using physical objects (like candles), not programs that run on your computer.

Dolphin simulates the existence of a sensor bar with fully emulated Wii remotes.

A controller with gyroscopes and a supported DSU Server would give you the behavior you are asking for.
