Made explanation of interaction between device class enable options (-[no]mouse, -[no]joystick, -[no]lightgun) and automatic device class enable options (-*_device) more explicit. Also documented that -mouse_device mouse is set by default in both relevant places. Provided a better explanation of the purpose of -dual_lightgun.

Windows-Specific Command-line Options
|
|
=====================================
|
|
|
|
This section contains configuration options that are specific to the native
|
|
(non-SDL) Windows version of MAME.
|
|
|
|
|
|
|
|
Performance options
|
|
-------------------
|
|
|
|
.. _mame-wcommandline-priority:
|
|
|
|
**-priority** *<priority>*
|
|
|
|
Sets the thread priority for the MAME threads. By default the priority is
|
|
left alone to guarantee proper cooperation with other applications. The
|
|
valid range is -15 to 1, with 1 being the highest priority. The default is
|
|
*0* (*NORMAL priority*).
|
|
|
|
.. _mame-wcommandline-profile:
|
|
|
|
**-profile** *[n]*
|
|
|
|
Enables profiling, specifying the stack depth of *[n]* to track.
|
|
|
|
|
|
Full screen options
|
|
-------------------
|
|
|
|
.. _mame-wcommandline-triplebuffer:
|
|
|
|
**-[no]triplebuffer** / **-[no]tb**
|
|
|
|
Enables or disables “triple buffering”. Normally, MAME just draws directly
|
|
to the screen, without any fancy buffering. But with this option enabled,
|
|
MAME creates three buffers to draw to, and cycles between them in order. It
|
|
attempts to keep things flowing such that one buffer is currently displayed,
|
|
the second buffer is waiting to be displayed, and the third buffer is being
|
|
drawn to. **-triplebuffer** will override **-waitvsync**, if the buffer is
|
|
successfully created. This option does not work with **-video gdi**. The
|
|
default is OFF (**-notriplebuffer**).
|
|
|
|
.. _mame-wcommandline-fullscreenbrightness:
|
|
|
|
**-full_screen_brightness** *<value>* / **-fsb** *<value>*
|
|
|
|
Controls the brightness, or black level, of the entire display. The
|
|
standard value is 1.0. Lower values (down to 0.1) will produce a darkened
|
|
display, while higher values (up to 2.0) will give a brighter display. Note
|
|
that not all video cards have hardware to support this option. This option
|
|
does not work with **-video gdi**. The default is *1.0*.
|
|
|
|
.. _mame-wcommandline-fullscreencontrast:
|
|
|
|
**-full_screen_contrast** *<value>* / **-fsc** *<value>*
|
|
|
|
Controls the contrast, or white level, of the entire display. The standard
|
|
value is 1.0. Lower values (down to 0.1) will produce a dimmer display,
|
|
while higher values (up to 2.0) will give a more saturated display. Note
|
|
that not all video cards have hardware to support this option. This option
|
|
does not work with **-video gdi**. The default is *1.0*.
|
|
|
|
.. _mame-wcommandline-fullscreengamma:
|
|
|
|
**-full_screen_gamma** *<value>* / **-fsg** *<value>*
|
|
|
|
Controls the gamma, which produces a potentially nonlinear black to white
|
|
ramp, for the entire display. The standard value is 1.0, which gives a
|
|
linear ramp from black to white. Lower values (down to 0.1) will increase
|
|
the nonlinearity toward black, while higher values (up to 3.0) will push the
|
|
nonlinearity toward white. Note that not all video cards have hardware to
|
|
support this option. This option does not work with **-video gdi**. The
|
|
default is *1.0*.
|
|
|
|
|
|
|
|
Input device options
|
|
--------------------
|
|
|
|
.. _mame-wcommandline-duallightgun:
|
|
|
|
**-[no]dual_lightgun** / **-[no]dual**
|
|
|
|
Controls whether or not MAME attempts to track two lightguns that appear as
|
|
a single mouse. This option requires the :ref:`lightgun option
|
|
<mame-commandline-nolightgun>` to be on and the :ref:`lightgunprovider
|
|
option <mame-commandline-lightgunprovider>` to be set to *win32*.
|
|
|
|
This option supports certain older dual lightgun setups that work by setting
|
|
the mouse pointer location at the moment a lightgun trigger is activated.
|
|
The primary and secondary triggers on the first lightgun correspond to the
|
|
first and second mouse buttons, and the primary and secondary triggers on
|
|
the second lightgun correspond to the third and fourth mouse buttons.
|
|
|
|
If you have multiple lightguns connected, you will probably just need to
|
|
enable the :ref:`lightgun option <mame-commandline-nolightgun>`, use the
|
|
default :ref:`lightgunprovider option <mame-commandline-lightgunprovider>`
|
|
of *rawinput*, and configure each lightgun individually.
|
|
|
|
The default is OFF (**-nodual_lightgun**).
