Most games (should) also support keyboard controls for users who don't own joysticks. Most commonly used keys are:
* [['''Cursor keys & SPACE]] ''' - This is '''not''' good for CPC 464 and 664 (which have uncomfortably arranged cursor keys) (only the 6128 and CPC+ do have modern cursor keys; as do emulators with PC keyboards)* [['''Q,A,O,P,SPACE]] ''' - This is a good solution, and it's sorts of standard (used by many games)
Best would be to implement both of the above solutions. Q-A-O-P is of course for english QWERTY keyboards, on french AZERTY it'd be A-Q-O-P (either way, the bits in the keyboard matrix are the same).
