Controls should work now. Input panel remapping is needed, also make sure mouse is not mapped to either port. PC mouse is needed for light gun emulation.
ALG joystick port usage:
Port 1:
- Joy Up = Service mode
- Joy Down = Start
- Joy Left = Left Coin
- Joy Right = Right Coin
Port 2:
- Light Gun
- 3rd button = Trigger
- Joy Up = Holster (Reload)
Not that it helps much, game is totally unplayable without visible targets.. But at least calibration screen works
