# Setting PPJoy global options

PPJoy has a number of global options that affects the operation of one or more interfaces. The options screen, shown below, can be activated by clicking on the Options button in the main PPJoy screen.

Currently PPJoy supports the following options:

- Debug PPM RC interface: Setting this option causes PPJoy to make a click (toggle speaker state) every time it detects an incoming pulse from PPM interface (LPT IRQ triggered). When the interface is working properly you should hear a steady tone.

- Debug Playstation interfaces: Setting this option causes PPJoy to make a click each time it reads an invalid/corrupted data packet from a playstation controller.

- Don't allocate ports to assigned joysticks: This option only affects PPJoy on Windows 2000, XP and 2003. When it is set PPJoy acts the same way is does on Windows 98, Me where it does not allocate a parallel port when a joystick is configured. Thus you do not have to disable PPJoy to use a printer connected to the parallel port.

  It is recommended that you do not turn on this option. Turning on this option may interfere with printing and will also disable the PPM RC interface. You need to restart your computer for changes to this option to take effect.
