There are some common keyboard configurations used:
* '''Joystick''' - This configuration is compatible with all Amstrad machines, even the GX4000 and you need to scan only one keyboard line (this means you can't be faster)
* '''Cursor keys & SPACE''' - This configuration is often used and is great for the CPC6128 and Plus and playing using emulators. This is '''not''' good for CPC 464 and 664 (which have uncomfortably arranged cursor keys)
