For the Amstrad's two-button joysticks. The quality isn't spectacular, so most CPC users tended to use third-party sticks, with only 1-button, but better quality. The JY-2 version contains a connector for a second joystick (equivalent to a built-in Y-cable). == Official CPC+/GX4000, Amstrad seems to have also made Joypads (which == [[Image:Gx4000.jpg|50px|right]]The CPC+ and GX4000 were shipped with one or two digital joypads included. Technically, they work identically same as normal joysticks. But, they have two buttons. And, the GX4000 doesn't have a keyboard which could be used instead of a second fire button. In result, some CPC+/GX4000 games may rely on 2-button hardware, making them incompatible with regular 1-button joysticks).

All Atari-compatible digital joysticks with ''Single Fire Button and Four Direction switches'' should be usually working with the CPC. For example, classic Competition Pro joysticks. == CPC+/GX4000 Joypads == or the [[Image:Gx4000.jpg|50px|rightKonix Speedking]]The CPC+ and GX4000 were shipped with one or two digital joypads included.

In result, some CPC+/GX4000 games may rely on 2-button hardware, making them incompatible with regular 1-button joysticks.

The CPC+/GX4000 have two digital joystick ports (which work equivalent to the an incompletely implemented Y-cablewith only 8 diodes - there are no diodes in the fire button lines, so fire buttons '''do not work properly''' with two players).

There are some common keyboard configurations used: * [[Digital '''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) * '''Q,A,O,P,SPACE''' - (Q up, A down, O left, P right, SPACE fire) ** This is a good solution, and it's a sort of standard (used by many games). ** Note: On french keyboards it'd be A,Q,O,P - anyways, the "UP" key is always Row8.Bit3, no matter if it's locally called "Q" (english QWERTY keyboard), or "A" (french AZERTY keyboard). Best would be to support joysticks, plus the above two keyboard mappings. Best to support them all at once (without needing the user select which one to use). In addition, it is also nice if the keys could be redefined but that is not necessary. == Relevant locations in Keyboard Matrix == {|{{Prettytable|width: 700px; font-size: 2em;}}|''Direction''||''Joystick Related]]1''||''Joystick 2''||''Cursor,Space''||''Q,A,O,P,Space''|-|Up ||Row9.Bit0 ||Row6.Bit0 (6) ||Row0.Bit0 ||Row8.Bit3 (Q)|-|Down ||Row9.Bit1 ||Row6.Bit1 (5) ||Row0.Bit2 ||Row8.Bit5 (A)|-|Left ||Row9.Bit2 ||Row6.Bit2 (R) ||Row1.Bit0 ||Row4.Bit2 (O)|-|Right ||Row9.Bit3 ||Row6.Bit3 (T) ||Row0.Bit1 ||Row3.Bit3 (P)|-|Fire2 ||Row9.Bit4 ||Row6.Bit4 (G) ||Row5.Bit7 ||Row5.Bit7 (Space)|-|Fire1 (*) ||Row9.Bit5 ||Row6.Bit5 (F) ||(wherever) ||(wherever)|-|}(*) Mind that Fire1 isn't supported on normal 1-button joysticks. When using it, also provide an alternate key on the keyboard.
