Changes

Some modification occured in the Amstrad "Atari" standard, 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.  Not that it was changed compaired to Old CPC generation (yet few CPC games actually supported the 2 button feature, despite available. Of course the Atari standard was originally a 1 button solution (Atari 8 bit consoles) but cxould easily be improuved to more buttons. Sega Megadrives managed easily 6-8 button (Street Fighter 2 standard). The most notable differences with other consoles using the Atari spec is with Sega systems (Master System and Megadrive).Yet simple re-cabling can be achieved thanks to proper adapter made simply :* a pair of "Atari / 9 pin serial" connectors (one male and one female) *and simply rewire between both as fit. This allows to keep the original configuration of Sega compatible Pads/joysticks and benefit from the higher quality level from them. A clever move may be to put such converter as a box with wires easily removable/changeable (not soldered, but inserted thank to proper solutions). This would allows to configure more easily different configuration *Sega Master system or MegaDrive/Genesis*Mais even be suitable with Seag LightGuns if you can find a proper Power source.  As a result is may be a problem to find proper Joysticks for your PLUS/GX4000 with benefit from 2nd button, as Sega models won't often fit and are often of a better quality/availability. Other noable differences are compaired to Atari ST as the mouse can''WHAT? t fit unless powered.As a result, different Mouse standards appeared on Amstrad, using Joystick port Or Extension port.The digital joystick should be same as ever? Theoreticallygoes with lightphaser solutions. Both could use Joystick port (added power suplly) or Extension port, only or even the new analog joystick special LightGun port is nonstandardon Plus range (Is it powered ?). by adding a power derivation on their Joystick port, Amstrad could have standardised it'''s technology and ease the CPC community.
