This games is pehaps the only one on Amstrad GX4000/Plus range to enable the use of an [[Analog Joysticks| Analog Joystick]], for the 2nd player.
+
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:
* Player 1 can use Digital Joystick #1
+
* Digital Joystick #1 and Digital Joystick #2
* Player 2 can use Digital Joystick #2, or alternately, Analog Joystick #1
+
or alternately (selectable in Options),
* [uhhhh... that can't be correct since digital-stick1 and analog-stick1 use the same fire button...?]
+
* Analog Joystick #1 and Digital Joystick #2
The game converts the analog inputs to digital-joystick-style "on/off" signals, so it isn't actually supporting "fast/slow" analog inputs.
+
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).

Analog Joystick Support

This game is perhaps the only one on Amstrad GX4000/Plus range that supports an 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.
