How to play for two?? (Micro Machines World Series)

The joystick is connected, well, the game does not see it.
On the keyboard you can play only 1 player, no where to set the controls for the second player.

The developers themselves have written that you can play on 1 screen up to 4 players!
[On one screen (HotSeat):(4 players, keyboard + gamepad)]
