Ds2vJoy determines in each mode, which vJoy or Xoutput number is its own.

- Limited to 4.
- for example if it is set to 3 and only one Ds2vJoy is active, it will be 1, so Joystick1/Player1, but if four Ds2vJoy are active at the same time, it will of course be Joystick3/Player3; and not depending on the launch order of Ds2vJoys.
