Digital Joysticks
From CPCWiki - THE Amstrad CPC encyclopedia!
AMSTRAD CPC Joystick
"As Amstrad CPC do sport only one Joystick connection, it is possible to customise some kind of 6 button Joystock quite easily, using the 4 directions of the second button as additionnal fire, for use in 1 player games. Such a custom device would need 2 controllers connectors to be used on an Amstrad plus." Huh?
Is this true?
Some modification occured, especially for the PLUS range as Amstrad aimed the console market (GX4000) and used a politic of "Exclusive Hardware" like all console manufacturers of the time.
As a result is may be a problem to find proper Joysticks for your PLUS/GX4000 WHAT? The digital joystick should be same as ever? Theoretically, only the new analog joystick port is nonstandard?
