This section contains configuration options that are specific to any build supported by SDL (including Windows when built with SDL instead of native).
.. _mame-scommandline-sdlvideofps:
-[no]sdlvideofps
Enable output of benchmark data on the SDL video subsystem, including your
system’s video driver, X server (if applicable), and OpenGL stack in
**-video opengl** mode.
.. _mame-scommandline-centerh:
-[no]centerh
Center horizontally within the view area. Default is ON (**-centerh**).
.. _mame-scommandline-centerv:
-[no]centerv
Center vertically within the view area. Default is ON (**-centerv**).
.. _mame-scommandline-scalemode:
-scalemode
Scale mode: none, async, yv12, yuy2, yv12x2, yuy2x2 (**-video soft** only).
Default is *none*.
.. _mame-scommandline-keymap:
-keymap
Enable keymap. Default is OFF (**-nokeymap**)
.. _mame-scommandline-keymapfile:
-keymap_file <file>
Keymap file name. Default is ``keymap.dat``.
.. _mame-scommandline-enabletouch:
-enable_touch
Enable support for touch input. If this option is switched off, mouse input
simulated from touch devices will be used instead. Default is OFF
(**-noenable_touch**)
.. _mame-scommandline-sixaxis:
-sixaxis
Use special handling for PlayStation 3 SixAxis controllers. May cause
undesirable behaviour with other controllers. Only affects the ``sdljoy``
joystick provider. Default is OFF (**-nosixaxis**)
.. _mame-scommandline-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 *sdl*.
This option supports 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.
The default is OFF (**-nodual_lightgun**).
.. _mame-scommandline-lightgunindex:
| | -lightgun_index1 <name> | -lightgun_index2 <name> | ... | -lightgun_index8 <name> |
Device name or ID mapped to a given lightgun slot.
.. _mame-scommandline-videodriver:
-videodriver <driver>

.. _mame-scommandline-audiodriver:
-audiodriver <driver>
SDL audio driver to use ('alsa', 'arts', ... or '*auto*' for SDL default)
.. _mame-scommandline-gllib:
-gl_lib <driver>
Alternative **libGL.so** to use; '*auto*' for system default
