--- Comment #3 from Esme Povirk madewokherd@gmail.com --- Looks like monoDX has this field, but it's not found because it's missing modopt(Microsoft.VisualC.IsConstModifier).
I checked the launcher's inports, and it also uses the following unimplemented methods from Microsoft.DirectX.DirectInput: new Device(System.Guid) KeyboardState Device.GetCurrentKeyboardState() bool KeyboardState.get_Item(Key) DeviceInstance Device.get_DeviceInformation() void Device.Acquire() void Device.Unacquire() Device.operator=(Device, Device) JoystickState Device.get_CurrentJoystickState() int JoystickState.get_X() int JoystickState.get_Y() int JoystickState.get_Z() int JoystickState.get_Rx() int JoystickState.get_Ry() int JoystickState.get_Rz() int[] JoystickState.GetSlider() new JoystickState() byte[] JoystickState.GetButtons() int[] JoystickState.GetPointOfView()
