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 or the [[Konix Speed King.Speedking]].

The CPC+/GX4000 have two digital joystick ports (which work equivalent to the an incompletely implemented Y-cable). == Other hardware that can be connected to with only 8 diodes - there are no diodes in the CPC joystick port == The CPCs digital joystick port is occasionally also misused to connect other hardwarefire button lines, known examples are:Some Lightguns: ([[Gunstick]], [[Loriciel Phaser (West Phaser)|West Phaser]]).Amstradso fire buttons 's Lightpen ([[Amstrad LP-1 light pen]]).And, various mouse interfaces ([[AMX Mouse]], [[Atari-ST mouse adapter]], [[dk'tronics Mouse Interface|Dk'tronics Mouse Interface]], [[CPC-Mousepack 2.0]], [[GEOS mouse|GEOS mouse]]). On the original CPCs, the direction/button inputs can be reprogrammed as outputs (via PSG/PPI config). However, this will NOT do not work on the CPC+/GX4000properly's dual joystick ports - which include diodes (like normal joystick Y-cables'' with two players).

In the CPC world it is more common that a game supports both keyboard and digital joystick and keyboard for those users who don't own joysticks.In addition, it is also nice if the keys could be redefined but that is not necessary.

* '''Cursor keys & SPACE''' - ** This configuration is often used and is great for the CPC6128 and Plus and playing using emulators. ** This is '''notgood''' 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). It ** Note: On french keyboards it'd be A,Q,O,P - anyways, the "UP" key is best for always Row8.Bit3, no matter if it's locally called "Q" (english QWERTY keyboardskeyboard), on 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'd 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 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 (but because the decoding of the keys is done in softwareG) ||Row5.Bit7 ||Row5.Bit7 (Space)|-|Fire1 (*) ||Row9.Bit5 ||Row6.Bit5 (F) ||(wherever) ||(wherever)|-|}(*) Mind that Fire1 isn't supported on normal 1-button joysticks.
