during gameplay and released otherwise (in menu, videos, console or if
game is paused).
**in_sdlbackbutton**: Defines which button is used in the gamepad or
joystick as the `Esc` key, that is, to be able to access the menu
and 'cancel'/'go back' on its options. When set to `0` (the default)
the Back/Select/Minus button is used. Set this to `1` to use the
Start/Menu/Plus button, and to `2` to use the Guide/Home/PS button.
Requires a game restart when changed.
* **singleplayer**: Only available in the dedicated server. Vanilla
Quake II enforced that either `coop` or `deathmatch` is set to `1`
when running the dedicated server. That made it impossible to play
