Changes
* Both digital joysticks should be selectable to use. The Amstrad plus has both connectors, the CPC can have a second joystick using a joystick splitter or using one of the official Amstrad Joysticks.
* Analogue joystick on Plus should be selectable if Plus machine is used. You can detect if a Plus machine exists programatically. Analogue joystick can be used as an alternative to a digital joystick (this avoids "Keyboard Clash" when used in 2 player games in conjunction with keyboard or another digital joystick)or to their full analogue ability where it makes sense in the game.
* It should be possible to select "No Sound", "Music", "Sound Effects" or "Music and Sound Effects" (where possible).
