SUMMARY
Joyflt.exe is a driver that represents two filter drivers in one. The first driver sits on top of the joystick driver and examines the data returned by the joystick driver. The second filter sits on top of the keyboard class driver. If the filter detects that a button has been pressed, it adds the appropriate raw keystroke to the keyboard buffer.
For example, pressing button two on the joystick adds the letter "g" to the keyboard buffer. In a flight simulation, the letter "g" is often used to raise and lower the landing gear. Now you do not have to remove your hand from the joystick to press the letter "g". Instead, you can accomplish this by pressing button two on the joystick. The joystick filter detects this and the keyboard filter pushes the "g" onto the keyboard buffer.
