Changes
* Connector for second joystick (JY-2 only)
* JY-1 has only one single fire button (at the top), plus connector for second joystick, the JY-1 doesn't use microswitches
* JY-2 has two fire buttons (one at top and one for the trigger), plus connector for second joystick
* JY3 had a different design, the "trigger" button was moved to the bottom, ''unknown if it featured a connector for 2nd joystick (?)''
