Changes
It is not that easycan also support LightGuns or Lightpens, especially for the PLUS rangeand mousescan be achieved using it too. '''WHAT? The digital joystick should be same as ever? Theoretically, only the new analog joystick port is nonstandard?'''
But may put some difficulties with the PLUS range.
Amstrad aimed the console market (GX4000) and used some kind of 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). And of course the Atari standard was originally a 1 button solution (Atari 8 bit 2600 consoles) but could 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 specs is with Sega systems (Master System and Megadrive) as the Atari standard became Sega standard (most sold console using this standard) Yet simple re-cabling can be achieved thanks to get a 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 too may be to put such converter as a box with wires easily removable/changeable (not soldered, but inserted thank to proper solutions). (A clever move from Amstrad may have been to use SEGA standards). This would allows to configure more easily different configurations depending on the Game controllers you may find. *Sega Master system or MegaDrive/Genesis*Mais even be suitable with Sega LightGuns or Atari/Amiga mouses if you can find a proper Power source and perhaps cables with a bit of electronic composents integrated (diodes, resistors ?). As a result it may be a problem to find proper Joysticks for your PLUS/GX4000 with benefit from 2nd button, as Sega models won't often fit entirely but are often of a better quality/availability. Megadrive paddles use Start button as Amstrad fire1 and Button 1 as Amstrad Button 2. Other noable differences are compaired to Atari ST as the mouse can't fit unless powered.As a result, different Mouse standards appeared on Amstrad, using Joystick port Or Extension port.The same goes with lightphaser solutions. Both could use Joystick port (added power suplly) or Extension port, or even the special LightGun port on 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. ==Getting more buttons== Amstrad CPC does sport only one Joystick connector, yet a simple montage allows to dispatch 2 joysticks on the same connector. The Plus range features this internally. But as a result it is theorically possible to customise some kind of 6+ buttons Joystick quite easily, if only software would support this. *Simplest way : using the 4 directions of the second Joystick (on a plus or using a Y-double connector/cable on a CPC) as additionnal Fire Buttons, easy to use in 1 player games : you then put one joypad in each hand (the "nunchaku" technic). *Meaner way : re-cable a modern joystick/paddle/game controller sporting a shitton of buttons...a Playstation gamepad may be re-wired a such to allows a total of easily 10or12 buttons Explanation : 4 directions per joysticks (8), and 1-2 buttons per joysticks (+2 or +4)... Perhaps even more as the Fire3 is undocumented yet seems used in AMX mouse... but did it used such integrated joystick doubler...? Such a custom device would need 2 controllers connectors to be used on an Amstrad plus, but may be implemented directly for a CPC (old) usage. ==Finding proper joysticks== It is not that easy, especially for the PLUS range which may make full use of the 2-buttons features (Cartridges games) or when dealing with modern CPC/Plus games including this feature in gameplay. Some old CPC era games included a more flexible "redefine keys/controls" option so you could use the second button but post 1990 games rarely did actually... mostly because the gameplay was rarely conceived to include more than one button. Even games with a second button needed often relied on keyboard and you couldn't even re-define the 2nd button's function if you have the chance to get a compatible 2-button Joystick. And even some Cartridge games where stricts "CPC to cart ports" and didn't even featured the 2 button option in their gameplay. Or unless you properly rewire a modern Joystick (completly possible and not even that hard, just find a proper connector and rewire all thoses with some diodes or resistors perhaps... Not that Amstrad was uncompatible with most Atari Standard joysticks. Most traditionnal controllers (with 1 button) working on Amiga 500 or Atari ST will work just fine on a good old CPC. But few games made use of the possibility to have a second button, yet some controllers did feature this alongside Autofire. Even 16bit comuter such as Amiga or Atari ST rarely made use of a 2-button per joystick gameplay (often you had to add some Keys with the keyboard to complete the gameplay...for Pause or Quit game, but also for alternatives firing sometimes, just like on some CPC games...) The "not that easy" part comes from the fact one of the simpler way is to use SEGA joysticks and paddles. Sega ranges of consoles (Master system and Genesis/megadrive) were the most common Atari Standard 2+ buttons user Hardwares. In a way the "9-pin Atari standard" had become the "IBM PC 9-pin serial" (mouses) or the "Sega Joystick standard" The commonest available "retro-vintage" 2+ buttons joysticks remains the sega ones. They may need some kind of adaptator then (to be done here or in a DIY page). ==Sega ControllersControlers==

Fire buttons A becomes Fire2 on Amstrad, and Select button becomes Fire 1 on Amstrad.
Not always practical, yet usable. Also if the game allows to re-define joystick/controls (not only keyboard) with enough flexibility, and if it can stand with the 2nd button, then it is 100% compatible...really, just "redefine keys" each time you run the programm.
Also the 16bit SEGA paddle is a lot better than the poor and faulty Amstrad Pad, so it remains a nice choice for every gamers, often and quite often easy to find.
You may even also get your hands on the rare "Amstrad Megadrive paddle " thx to the Amstrad PC with the megadrive inside(Amstrad Mega-PC ?), a must -have to all of us...
''Each button (left, right, button 1 ect.) is in fact a voltage(very small), this voltage is grounded to result in movement, fire, jump ect. For standard master system controllers this is directly feed to the system via wires only (some other controllers use a micro chip) they also are not connected to voltage, while some others do.
''The Sega Genesis (in Europe sold as Sega MegaDrive) pads are an extension to the Sega Master System pads. They use more buttons (3+1, 5+1, 6+1). They use the one usnused pin as a select pin for reading more buttons.''''
Those SMS standard controlers may be used alsmot unchanged on a CPC if the software allows to redefine controls. As a result The only change is that the button2 on CPC is button 1 on SMS. So you may use only one button : , the fire use of 2 wich buttons would need a "re-wiring" solution (a "flexible" modular adaptator may be the button 1 fine) so it can't always fit unchanged on the controllerPlus range.
It seems the "Power" button on SMS controlers is used when the controler is fitted with AutoFire option (needs to be checked) or when using the Lightgun.
But an external adapter may include such power-supply feature too so may works well with some mouses or Lightguns if software support thoses.
==Nunchakus technique==
If the game allows to redefine controls and the use of 2 joysticks, then you use :
(using your thumb)
*Right Hand as firing one(direction+2 buttons), with a second paddle turned 90° Counterclockwise:Access to fire 1 and 2 with the thumb.
*Right hand easily achieve a 4 fire button config by using directional pad from the 2nd joypad (one for each thumb yet the cable would be a nuisance)
*or a fixed Joystick (any hand, directions) + a paddle (other hand, fires) may be fine too...
(pictures to come soon)
