[[Image:Joy-Y.jpg|thumb|Joystick Y-cable]]
These Y-cables for [[Digital Joysticks]] were made by 3rd party vendors as a replacement to the original [[Amstrad JY-1/JY-2 joysticks|JY-2 joystick]] for the Amstrad CPC computers.
In order to push sales of Amstrad's own joysticks, Amstrad designed the CPC with one joystick port only which had two common signal pins. The idea was to sell one joystick which forwarded the second common signal to a built-in joystick port, to which the second joystick could be connected.
For example, if Player 1 moves UP-'''and'''-RIGHT then UP and RIGHT are shortcut with each other. In result, without the diodes, Player 2 would automatically move UP-'''and'''-RIGHT whenever trying to move UP-'''or'''-RIGHT.
'''Caution:''' The diodes are, CPC+ has some kind of course, needed built-in Y-cable with only on one connector (eg8 diodes. Joystick But, for properly supporting the included 2 only). The schematics with -button joypads it would require 12 diodes on both Joystick 1 and 2 connectors are a bit overcomplicated. Normally only 5 diodes are required (or 7 when implementing the extra fire buttons).
