* The steering wheel works. * The pedals work. * The side panel (joystick and buttons) can be used and some buttons can be freely assigned. * Not all switches and functions are natively supported. You’ll need to map some buttons yourself, and certain functions of the panel cannot be used in BS21 or require additional software. (e.g. JoyToKey or similar tools). There is no official 100% support for the side panel in Bus Simulator 21.
