== Analog Joystick Support ==
	 
This game is perhaps the only one on Amstrad GX4000/Plus range that supports an [[Analog Joysticks|Analog Joystick]], however, it converts the analog signals to digital signals by software. In two-player mode, the game can be controlled by:
* Digital Joystick #1 and Digital Joystick #2
or alternately (selectable in Options),
* Analog Joystick #1 and Digital Joystick #2
That feature is intended for people who own one digital stick, and one analogue stick (rather than two digital ones). In the "analog" mode, Digital Joystick #1 is not used (because its button inputs would conflict with Analog Joystick #1).

The keyboard is read to determine the state of the digital joysticks and the P button (pause button on gx4000 console).

The routine reads analogue input channel 0 and 1 for the analogue joystick and performs some checking to see the range of the numbers. Based on this it sets the direction pressed.
