NAME

       MAME - The Multiple Arcade Machine Emulator

SYNOPSIS

       mame [options] gamename

DESCRIPTION

       Started  in 1997 by Nicola Salmoria, MAME was originally intended as a series of emulators
       for individual games, which were later combined into a single multi-game emulator. In  the
       following  years,  MAME  grew  over  and  over  up  to the actual size, with more than 100
       contributors to the project.

OPTIONS

   Core commands
       -help, -?
              Displays current MAME version and copyright notice.

       -validate, -valid
              Performs internal validation on  every  driver  in  the  system.  Run  this  before
              submitting  changes  to  ensure  that  you  haven't violated any of the core system
              rules.

   Configuration commands
       -createconfig, -cc
              Creates the default mame.ini file in the current directory. All  the  configuration
              options  (not  commands) described below can be permanently changed by editing this
              configuration file.

       -showconfig, -sc
              Displays the current configuration settings.

       -showusage, -su
              Displays a summary of all the command  line  options.  For  options  that  are  not
              mentioned here, the short summary given by mame -showusage is usually sufficient.

   Frontend commands
       NOTE: By default, all the '-list' commands below write info to the screen.  If you wish to
       write  the  info  to  a  textfile  instead,  use  redirection,  e.g.   mame   -listxml   >
       ~/mamelist.xml  writes  the  full list of supported game to file mamelist.xml in your home
       directory.

       -listxml, -lx [gamename|wildcard]
              List comprehensive details for all of the supported  games.  The  output  is  quite
              long,  so  it is usually better to redirect this into a file.  The output is in XML
              format. By default all games are listed;  however,  you  can  limit  this  list  by
              specifying a driver name or wildcard after the -listxml command.

       -listfull, -ll [gamename|wildcard]
              Displays  a  list  of  game driver names and descriptions. By default all games are
              listed; however, you can limit this list by specifying a driver  name  or  wildcard
              after the -listfull command.

       -listsource, -ls [gamename|wildcard]
              Displays  a  list  of  drivers and the names of the source files their game drivers
              live in. Useful for finding which driver a game runs on in order to  fix  bugs.  By
              default  all  games  are  listed;  however, you can limit this list by specifying a
              driver name or wildcard after the -listsource command.

       -listclones, -lc [gamename|wildcard]
              Displays a list of clones. By default all clones are listed; however, you can limit
              this list by specifying a driver name or wildcard after the -listclones command.

       -listbrothers, -lb [gamename|wildcard]
              Displays  a  list  of "brothers" or other drivers from same sourcefile.  By default
              all games are listed; however, you can limit this list by specifying a driver  name
              or wildcard after the -listbrothers command.

       -listcrc
              Displays  a  full  list  of CRCs of all ROM images referenced by all drivers within
              MAME code.

       -listroms gamename
              Displays a list of ROM images referenced by the specified game.

       -listsamples gamename
              Displays a list of samples referenced by the specified game.

       -verifyroms [gamename|wildcard]
              Checks for invalid or missing ROM images. By default all drivers  that  have  valid
              ZIP  files  or directories in the rompath are verified; however, you can limit this
              list by specifying a driver name or wildcard after the -verifyroms command.

       -verifysamples [gamename|wildcard]
              Checks for invalid or missing samples. By default all drivers that have  valid  ZIP
              files  or  directories  in the samplepath are verified; however, you can limit this
              list by specifying a driver name or wildcard after the -verifyroms command.

       -romident
              Attempts to identify ROM files, if they are known to MAME, in  the  specified  .zip
              file or directory. This command can be used to try and identify ROM sets taken from
              unknown boards. On exit, the errorlevel is returned as one of the following:
              0  all files were identified
              7  all files were identified except for some "non-ROM" files
              8  some files were identified
              9  no files were identified

       -listdevices, -ld
              Output the list of devices referenced by a given game or set of games.

       -listmedia, -lm
              Output the list of available media for the system.

       -listsoftware
              Output the list of known software for the system.

   Configuration options
       -[no]readconfig, -[no]rc
              Enables or disables the reading of the config files. When  enabled  (which  is  the
              default), MAME reads the following config files in order:
              1. mame.ini
              the main configuration file
              2. [name].ini
              where  name  is  your executable name, i.e. mame unless you changed it (e.g. if you
              renamed mame to mame0137, the parsed file will be mame0137.ini)
              3. debug.ini, if the debugger is enabled
              4. vector.ini, for vector games only
              5. [driver].ini
              based on the source filename of the game driver
              6. [parent].ini
              for clones only, may be called recursively
              7. [gamename].ini
              note this sometimes resolves to the same of the source driver
              The settings in the later ini's override those  in  the  earlier  ini's.   So,  for
              example,  if  you  wanted  to  disable overlay effects in the vector games, you can
              create a vector.ini with the "effect  none"  line  in  it,  and  it  will  override
              whatever effect value you have in your mame.ini. The default is ON (-readconfig).

   Search path options
       IMPORTANT:  Please  use  the path, directory and file options in mame.ini ONLY. Otherwise,
       the outcome may be unpredictable and not consistent across releases.

       -rompath, -rp, -biospath, -bp, pathname
              Specifies a list of paths within which to find ROM or hard disk  images.   Multiple
              paths  can  be specified by separating them with semicolons.  The default is 'roms'
              (that is, a directory "roms" in the same directory as the MAME executable).

       -samplepath, -sp pathname
              Specifies a list of paths within which to find sample files. Multiple paths can  be
              specified  by separating them with semicolons. The default is 'samples' (that is, a
              directory "samples" in the same directory as the MAME executable).

       -artpath, -artwork_directory pathname
              Specifies a list of paths within which to find artwork files. Multiple paths can be
              specified  by separating them with semicolons. The default is 'artwork' (that is, a
              directory "artwork" in the same directory as the MAME executable).

       -ctrlrpath, -ctrlr_directory pathname
              Specifies a list of paths within which to  find  controller-specific  configuration
              files.  Multiple  paths  can  be  specified by separating them with semicolons. The
              default is 'ctrlr' (that is, a directory "ctrlr" in the same directory as the  MAME
              executable).

       -inipath pathname
              Specifies  a  list  of paths within which to find .INI files. Multiple paths can be
              specified by separating them with semicolons. The default is '/etc/mame/'.

       -fontpath pathname
              Specifies a list of paths within which to find .BDF font files. Multiple paths  can
              be  specified  by  separating  them  with  semicolons. The default is '.' (that is,
              search in the same directory as the MAME executable).

       -cheatpath pathname
              Specifies a list of paths within which to find cheat files. Multiple paths  can  be
              specified  by  separating  them with semicolons. The default is 'cheat' (that is, a
              directory "cheat" in the same directory as the MAME executable).

       -crosshairpath pathname
              Specifies a list of paths within which to find crosshair files. Multiple paths  can
              be  specified  by separating them with semicolons. The default is 'crosshair' (that
              is, a directory "crosshair" in the same directory as the MAME executable).  If  the
              Crosshair  is  set  to  default  in  the menu, MAME will look for gamenamespecified
              crosshairpath, where # is the player number.  Failing that, MAME will use  built-in
              default crosshairs.

   Output Directory Options
       -cfg_directory pathname
              Specifies  a  single directory where configuration files are stored.  Configuration
              files store user configurable settings that are read at startup  and  written  when
              MAME  exits. The default is 'cfg' (that is, a directory "cfg" in the same directory
              as the MAME executable). If this directory does not exist, it will be automatically
              created.

       -nvram_directory pathname
              Specifies  a  single  directory where NVRAM files are stored. NVRAM files store the
              contents of EEPROM and non-volatile RAM (NVRAM) for games which used this  type  of
              hardware.  This data is read at startup and written when MAME exits. The default is
              'nvram'  (that  is,  a  directory  "nvram"  in  the  same  directory  as  the  MAME
              executable). If this directory does not exist, it will be automatically created.

       -memcard_directory pathname
              Specifies  a single directory where memory card files are stored. Memory card files
              store the contents of removable memory cards for games  which  used  this  type  of
              hardware.  This  data is read and written under control of the user via the "Memory
              Card" menu in the user interface. The default is 'memcard' (that  is,  a  directory
              "memcard" in the same directory as the MAME executable). If this directory does not
              exist, it will be automatically created.

       -input_directory pathname
              Specifies a single  directory  where  input  recording  files  are  stored.   Input
              recordings  are  created  via  the -record option and played back via the -playback
              option. The default is 'inp' (that is, a directory "inp" in the same  directory  as
              the  MAME  executable).  If this directory does not exist, it will be automatically
              created.

       -state_directory pathname
              Specifies a single directory where save state files are stored.  Save  state  files
              are  read and written either upon user request, or when using the -autosave option.
              The default is 'sta' (that is, a directory "sta" in the same directory as the  MAME
              executable). If this directory does not exist, it will be automatically created.

       -snapshot_directory pathname
              Specifies  a  single directory where screen snapshots are stored, when requested by
              the user. The default is 'snap' (that is, a directory "snap" in the same  directory
              as the MAME executable). If this directory does not exist, it will be automatically
              created.

       -diff_directory pathname
              Specifies a single directory where hard drive differencing files are  stored.  Hard
              drive  differencing files store any data that is written back to a hard disk image,
              in order to preserve the original image. The  differencing  files  are  created  at
              startup  when  a  game  with  a  hard disk image. The default is 'diff' (that is, a
              directory "diff" in the same directory as the MAME executable). If  this  directory
              does not exist, it will be automatically created.

       -comment_directory pathname
              Specifies  a  single  directory  where debugger comment files are stored.  Debugger
              comment files  are  written  by  the  debugger  when  comments  are  added  to  the
              disassembly  for a game. The default is 'comments' (that is, a directory "comments"
              in the same directory as the MAME executable).  If this directory does  not  exist,
              it will be automatically created.

   State/playback options
       -state slot
              Immediately  after  starting  the  specified game, will cause the save state in the
              specified slot to be loaded.

       -[no]autosave
              When enabled, automatically creates  a  save  state  file  when  exiting  MAME  and
              automatically  attempts  to  reload it when later starting MAME with the same game.
              This only works for games that have explicitly enabled save state support in  their
              driver. The default is OFF (-noautosave).

       -playback, -pb filename
              Specifies a file from which to play back a series of game inputs. This feature does
              not work reliably for all games, but can be used to  watch  a  previously  recorded
              game  session  from start to finish. In order to make things consistent, you should
              only record and playback with all configuration (.cfg),  NVRAM  (.nv),  and  memory
              card files deleted. The default is NULL (no playback).

       -record, -rec filename
              Specifies  a  file  to  record  all  input from a game session. This can be used to
              record a game session for later playback. This feature does not work  reliably  for
              all  games,  but can be used to watch a previously recorded game session from start
              to finish. In order to make things consistent, you should only record and  playback
              with  all  configuration  (.cfg),  NVRAM  (.nv), and memory card files deleted. The
              default is NULL (no recording).

       -snapname name
              Describes how MAME should name files for snapshots. name is a string that  provides
              a  template  that  is  used  to generate a filename. Three simple substitutions are
              provided: the / character represents the path  separator  on  any  target  platform
              (even  Windows);  the string %g represents the driver name of the current game; and
              the string %i represents an  incrementing  index.  If  %i  is  omitted,  then  each
              snapshot  taken will overwrite the previous one; otherwise, MAME will find the next
              empty value for %i and use that for a filename. The default is %g/%i, which creates
              a  separate  folder  for  each game, and names the snapshots under it starting with
              0000 and increasing from there.

       -snapsize widthxheight
              Hard-codes the size for snapshots and movie recording. By default, MAME will create
              snapshots at the game's current resolution in raw pixels, and will create movies at
              the game's starting resolution in raw pixels. If you specify this option, then MAME
              will  create  both  snapshots  and  movies at the size specified, and will bilinear
              filter the result. Note that this size does not automatically rotate if the game is
              vertically oriented. The default is 'auto'.

       -snapview viewname
              Specifies the view to use when rendering snapshots and movies. By default, both use
              a special 'internal' view, which renders a separate snapshot per screen or  renders
              movies  only  of the first screen. By specifying this option, you can override this
              default behavior and select a single view that will  apply  to  all  snapshots  and
              movies.   Note  that  viewname does not need to be a perfect match; rather, it will
              select the first view whose name matches all the characters specified by  viewname.
              For  example,  -snapview native will match the "Native (15:14)" view even though it
              is not a perfect match.  viewname can also be 'auto', which selects the first  view
              with all screens present. The default value is 'internal'.

       -mngwrite filename
              Writes each video frame to the given filename in MNG format, producing an animation
              of the  game session. Note that -mngwrite only writes video  frames;  it  does  not
              save  any  audio data. Use -wavwrite for that, and reassemble the audio/video using
              offline tools. The default is NULL (no recording).

       -aviwrite filename
              Stream video and sound data to the given  filename  in  AVI  format,  producing  an
              animation  of  the  game  session  complete  with  sound.  The  default is NULL (no
              recording).

       -wavwrite filename
              Writes the final mixer output to the given filename in  WAV  format,  producing  an
              audio recording of the  game session. The default is NULL (no recording).

       -[no]burnin
              Tracks brightness of the screen during play and at the end of emulation generates a
              PNG that can be used to simulate burn-in effects on other games. The resulting  PNG
              is  created  such  that  the  least used-areas of the screen are fully white (since
              burned-in areas are darker, all other areas of  the  screen  must  be  lightened  a
              touch).   The  intention  is that this PNG can be loaded via an artwork file with a
              low alpha (e.g, 0.1-0.2 seems to work well) and blended over the entire screen. The
              PNG     files     are     saved     in     the    snap    directory    under    the
              gamename\burnin-<screen.name>.png. The default is OFF (-noburnin).

   Performance options
       -[no]autoframeskip, -[no]afs
              Automatically determines  the  frameskip  level  while  you're  playing  the  game,
              adjusting  it  constantly  in  a  frantic  attempt to keep the game running at full
              speed. Turning this on overrides the value you have set for -frameskip  below.  The
              default is OFF (-noautoframeskip).

       -frameskip, -fs value
              Specifies  the frameskip value (autoframeskip must be disabled). This is the number
              of frames out of every 12 to drop when running. For example, if you say  -frameskip
              2,  then MAME will display 10 out of every 12 frames. By skipping those frames, you
              may be able to get full speed in a game that requires  more  horsepower  than  your
              computer has. The default value is 0, which skips no frames.

       -seconds_to_run, -str value
              This  option  can  be used for benchmarking and automated testing. It tells MAME to
              stop execution after a fixed number of seconds. By combining this with a fixed  set
              of  other  command  line  options,  you  can  set  up  a consistent environment for
              benchmarking MAME performance. In addition, upon exit, the -str option will write a
              screenshot called final.png to the game's snapshot directory.

       -[no]throttle
              Configures  the  default thottling setting. When throttling is on, MAME attempts to
              keep the game running at the game's intended speed. When throttling  is  off,  MAME
              runs the game as fast as it can. Note that the fastest speed is more often than not
              limited by your graphics card, especially  for  older  games.  The  default  is  ON
              (-throttle).

       -[no]sleep
              Allows  MAME  to  give  time  back to the system when running with -throttle.  This
              allows other programs to have some CPU time, assuming that the  game  isn't  taxing
              100%  of  your  CPU  resources.  This  option  can  potentially  cause  hiccups  in
              performance if other demanding programs are running.  The default is ON (-sleep).

       -speed Controls the speed of gameplay, relative to realtime; smaller numbers  are  slower.
              Default is 1.00.

       -refreshspeed, -rs
              Automatically adjusts the -speed parameter to keep the effective refresh rate below
              that of the lowest screen refresh rate.

       -multithreading, -mt
              Enable multithreading; this enables rendering and blitting on  a  separate  thread.
              The default is OFF.

       -numprocessors, -np
              Set number of processors; this overrides the number the system reports.

       -sdlvideofps
              Show SDL video performance.

   Rotation options
       -[no]rotate
              Rotate  the game to match its normal state (horizontal/vertical). This ensures that
              both vertically and horizontally oriented games show up correctly without the  need
              to rotate your monitor. If you want to keep the game displaying 'raw' on the screen
              the way it would have in the arcade, turn  this  option  OFF.  The  default  is  ON
              (-rotate).

       -[no]ror | -[no]rol
              Rotate  the  game  screen  to  the  right  (clockwise) or left (counter- clockwise)
              relative to either its normal state (if -rotate is specified) or its  native  state
              (if  -norotate  is specified). The default for both of these options is OFF (-noror
              -norol).

       -[no]autoror | -[no]autorol
              These options are designed for use with pivoting  screens  that  only  pivot  in  a
              single direction. If your screen only pivots clockwise, use -autorol to ensure that
              the game will fill the screen either horizontally  or  vertically  in  one  of  the
              directions  you  can  handle.   If  your  screen only pivots counter-clockwise, use
              -autoror.

       -[no]flipx

       -[no]flipy
              Flip (mirror) the game screen either horizontally (-flipx) or vertically  (-flipy).
              The  flips  are  applied  after  the -rotate and -ror/-rol options are applied. The
              default for both of these options is OFF (-noflipx -noflipy).

   Artwork options
       -[no]artwork_crop, -[no]artcrop
              Enable cropping of artwork to the game screen area only. This option  can  also  be
              controlled  via  the  Video  Options menu in the user interface. The default is OFF
              (-noartwork_crop).

       -[no]use_backdrops, -[no]backdrop
              Enables/disables the display of backdrops. The default is ON (-use_backdrops).

       -[no]use_overlays, -[no]overlay
              Enables/disables the display of overlays. The default is ON (-use_overlays).

       -[no]use_bezels, -[no]bezel
              Enables/disables the display of bezels. The default is ON (-use_bezels).

       -[no]use_cpanels, -[no]cpanel
              Enables/disables the display of cpanels. The default is ON (-use_bezels).

       -[no]use_marquees, -[no]marquee
              Enables/disables the display of marquees. The default is ON (-use_bezels).

   Screen options
       -brightness value
              Controls the default brightness, or black level, of the game screens.  This  option
              does  not affect the artwork or other parts of the display.  Using the MAME UI, you
              can individually set the brightness for each game screen; this option controls  the
              initial  value  for  all visible game screens. The standard value is 1.0. Selecting
              lower values (down to 0.1) will produce a darkened display, while selecting  higher
              values (up to 2.0) will give a brighter display. The default is 1.0.

       -contrast value
              Controls  the  contrast,  or white level, of the game screens. This option does not
              affect the artwork or other parts of the  display.  Using  the  MAME  UI,  you  can
              individually  set  the  contrast  for  each  game  screen; this option controls the
              initial value for all visible game screens. The standard value  is  1.0.  Selecting
              lower  values  (down  to 0.1) will produce a dimmer display, while selecting higher
              values (up to 2.0) will give a more saturated display. The default is 1.0.

       -gamma value
              Controls the gamma, which produces a potentially nonlinear black to white ramp, for
              the  game  screens.  This  option does not affect the artwork or other parts of the
              display. Using the MAME UI, you can  individually  set  the  gamma  for  each  game
              screen;  this  option  controls the initial value for all visible game screens. The
              standard value is 1.0, which gives a linear ramp from  black  to  white.  Selecting
              lower  values  (down  to  0.1)  will  increase the nonlinearity toward black, while
              selecting higher values (up to 3.0) will push the nonlinearity  toward  white.  The
              default is 1.0.

       -pause_brightness value
              This controls the brightness level when MAME is paused. The default value is 0.65.

   Vector rendering options
       -[no]antialias, -[no]aa
              Enables   antialiased   line   rendering  for  vector  games.  The  default  is  ON
              (-antialias).

       -beam width
              Sets the width of the vectors. This is a scaling factor against the standard vector
              width.  A value of 1.0 will keep the default vector line width. Smaller values will
              reduce the width, and larger values will increase the width. The default is 1.0.

       -flicker value
              Simulates a vector "flicker"  effect,  similar  to  a  vector  monitor  that  needs
              adjustment.  This  option  requires  a  float  argument in the range of 0.00-100.00
              (0=none, 100=maximum). The default is 0.

   Video options
       -video [soft|opengl|opengl16|none]
              Specifies which video subsystem to use for drawing:
              soft  uses software rendering, which is slower but more compatible.
              opengl  uses OpenGL and your graphics accelerator  to  speed  up  many  aspects  of
              drawing  MAME  including  compositing  artwork,  overlays,  and  bezels, as well as
              stretching the image to fit your screen.
              opengl16  uses alternate OpenGL code, which should provide faster  output  on  some
              cards.
              none  does no drawing and is intended for CPU benchmarking.
              Default is SOFT.

       -numscreens
              Reserved for future use.

       -[no]window, -[no]w
              Run  MAME  in  either full screen or a window. This is a fully-featured window mode
              where the window resizes as necessary to track what the game  does.   And  you  can
              resize  it   yourself  with your OS's standard window controls.  The default is OFF
              (-nowindow).

       -[no]maximize, -[no]max
              Controls initial window size in windowed mode. If it is set  on,  the  window  will
              initially be set to the maximum supported size when you start MAME. If it is turned
              off, the window will start out at the smallest supported size. This option only has
              an effect when the -window option is used. The default is ON (-maximize).

       -keepaspect, -ka
              Forces  the  correct  aspect  ratio.  This means when you're resizing the window in
              windowed mode the actual game image will resize in discrete steps to  maintain  the
              proper  shape  of the game graphics. If you turn this off you can resize the window
              to anything you like and get funny squishing and stretching.  The same applies  for
              full-screen. Default is ON (-keepaspect).

       -unevenstretch, -ues
              Allow  non-integer  stretch  factors.  Video purists should stay far, far away from
              this option, while everyone else will be happy to know that it lets  you  fill  the
              screen properly in full-screen mode. Default is ON (-unevenstretch).

       -effect
              Name of a PNG file to use for visual effects, or 'none'. Default is 'none'.

       -centerh
              Center horizontally within the view area. Default is ON (-centerh).

       -centerv
              Center vertically within the view area. Default is ON (-centerv).

       -waitvsync
              Enable  waiting  for  the  start of VBLANK before flipping screens; reduces tearing
              effects.

   Software video rendering subsystem options
       NOTE: All the options in this group  are  available  only  with  softare  video  rendering
       subsystem, i.e -video soft.

       -prescale
              Scale screen rendering by this amount in software. Default is 1.

       -scalemode, -sm [none|async|yv12|yuy2|yv12x2|yuy2x2]
              Hardware scaling mode.
              none    use software rendering.
              async   async overlay.
              yv12    yv12 overlay.
              yuy2    yuy2 overlay.
              yv12x2  yv12 overlay using x2 prescaling.
              yuy2x2  yuy2 overlay using x2 prescaling.
              Default is NONE.

   OpenGL video rendering subsystem options
       NOTE:  All  the  options  in  this  group  are  available only with OpenGL video rendering
       subsystem, i.e -video opengl or -video opengl16.

       -filter, -glfilter, -flt
              Enable bilinear filtering on screen output. Default is ON (-filter).

       -prescale
              Scale screen rendering by this amount in software. Default is 1.

       -gl_forcepow2texture
              Force power of two textures. Default is NO.

       -gl_notexturerect
              Don't use OpenGL GL_ARB_texture_rectangle. Default is ON: turn off (set this to  0)
              if corruption occurs in OpenGL mode, at cost of some performance loss.

       -gl_vbo
              Enable  OpenGL  VBO, if available, for a performance increase.  Default is ON: turn
              off (set this to 0) if corruption occurs.

       -gl_pbo
              Enable OpenGL PBO, if available, for a performance increase.  Default is  ON:  turn
              off (set this to 0) if corruption occurs.

       -gl_glsl
              Enable OpenGL GLSL, if available, for a performance increase.

       -gl_glsl_filter
              Enable  OpenGL GLSL filtering instead of FF filtering 0=plain, 1=bilinear.  Default
              is 1: bilinear.

       -glsl_shader_mame[0-9]
              Preferred custom OpenGL GLSL shader set mame bitmap (from 0 to 9).

       -glsl_shader_screen[0-9]
              Preferred custom OpenGL GLSL shader screen bitmap (from 0 to 9).

       -gl_glsl_vid_attr
              Enable OpenGL GLSL handling of brightness and contrast. Better RGB game performance
              for free. Default is ON.

       -resolution, -r
              Select  the  resolution to use in full-screen mode.  -switchres must be enabled for
              this to work.

       -screen

       -aspect, -screen_aspect

       -view

       -screen[0-3]

       -aspect[0-3]

       -resolution[0-3], -r[0-3]

       -view[0-3]
              All these options are reserved for future use.

   Full screen options
       -[no]switchres
              Affects full screen mode only. Chooses  if  MAME  can  try  to  change  the  screen
              resolution  (color  depth is normally left alone) when in full-screen mode. If it's
              off, you always get your desktop resolution  in  full-screen  mode  (which  can  be
              useful for LCDs).

       -useallheads
              Split full screen image across monitors.

   Sound options
       -[no]sound
              Enable or disable sound altogether. The default is ON (-sound).

       -samplerate, -sr value
              Sets  the  audio sample rate. Smaller values (e.g. 11025) cause lower audio quality
              but faster emulation speed. Higher values (e.g. 48000) cause higher  audio  quality
              but slower emulation speed. The default is 48000.

       -[no]samples
              Use samples if available. The default is ON (-samples).

       -volume, -vol value
              Sets  the startup volume. It can later be changed with the user interface (see Keys
              section). The volume is an attenuation in dB: e.g., "-volume -12" will  start  with
              -12dB attenuation. The default is 0.

       -audio_latency value
              This  controls  the  amount of latency built into the audio streaming.  The latency
              parameter controls the lower threshold. The default is  1  (meaning  lower=1/5  and
              upper=2/5). Set it to 2 (-audio_latency 2) to keep the sound buffer between 2/5 and
              3/5 full. If you crank it up to 4, you can definitely notice the lag.

   Input options
       -[no]coin_lockout, -[no]coinlock
              Enables simulation of the "coin lockout" feature that is implmeneted on a number of
              game  PCBs.  It was up to the operator whether or not the coin lockout outputs were
              actually connected to the  coin  mechanisms.  If  this  feature  is  enabled,  then
              attempts  to  enter a coin while the lockout is active will fail and will display a
              popup message in the user interface. If this feature is disabled, the coin  lockout
              signal will be ignored. The default is ON (-coin_lockout).

       -ctrlr controller
              Enables  support  for  special controllers. Configuration files are loaded from the
              ctrlrpath. They are in the same format as the .cfg files that are saved,  but  only
              control  configuration  data  is  read  from  the  file.  The  default  is NULL (no
              controller file).

       -[no]mouse
              Controls whether or not MAME looks for a mouse controller to use. Note that in many
              cases,  lightguns  are  treated as mice by the operating system, so you may need to
              enable this to enable lightgun support. When this is enabled, you will not be  able
              to use your mouse while playing a game. If you want to get control of your computer
              back, you will need  to  either  pause  the  game  or  quit.  The  default  is  OFF
              (-nomouse).

       -[no]joystick, -[no]joy
              Controls  whether  or not MAME looks for joystick/gamepad controllers.  The default
              is ON (-joystick).

       -[no]lightgun, -[no]gun
              Controls whether or not MAME makes use of lightgun  controllers.   Note  that  most
              lightguns  map  to  the  mouse,  so using -lightgun and -mouse together may produce
              strange results. The default is OFF (-nolightgun).

       -[no]multikeyboard, -[no]multikey
              Determines whether MAME differentiates between multiple  keyboards.   Some  systems
              may report more than one keyboard; by default, the data from all of these keyboards
              is combined so that it looks like a single keyboard. Turning this  option  on  will
              enable  MAME to report keypresses on different keyboards independently. The default
              is OFF (-nomultikeyboard).

       -[no]multimouse
              Determines whether MAME differentiates between  multiple  mice.  Some  systems  may
              report  more  than one mouse device; by default, the data from all of these mice is
              combined so that it looks like a single mouse. Turning this option on  will  enable
              MAME  to  report mouse movement and button presses on different mice independently.
              The default is OFF (-nomultimouse).

       -[no]steadykey, -[no]steady
              Some games require two or more buttons to be pressed at exactly the  same  time  to
              make  special  moves.  Due  to  limitations  in the PC keyboard hardware, it can be
              difficult or even  impossible  to  accomplish  that  using  the  standard  keyboard
              handling. This option selects a different handling that makes it easier to register
              simultaneous button presses, but has  the  disadvantage  of  making  controls  less
              responsive. The default is OFF (-nosteadykey).

       -[no]offscreen_reload, -[no]reload
              Controls  whether  or  not  MAME  treats a second button input from a lightgun as a
              reload signal. In this case, MAME will report the gun's position  as  (0,MAX)  with
              the  trigger  held, which is equivalent to an offscreen reload. This is only needed
              for games that required you to shoot offscreen to reload, and then only if your gun
              does not support off screen reloads. The default is OFF (-nooffscreen_reload).

       -joystick_map, -joymap map
              Controls   how   joystick   values   map   to   digital   joystick  controls.   See
              /usr/share/doc/mame/config.txt for full details on map format.

       -joystick_deadzone, -joy_deadzone, -jdz value
              If  you  play  with  an  analog  joystick,  the  center   can   drift   a   little.
              joystick_deadzone  tells how far along an axis you must move before the axis starts
              to change. This option expects a float in the range of 0.0 to 1.0. Where 0  is  the
              center of the joystick and 1 is the outer limit. The default is 0.3.

       -joystick_saturation, -joy_saturation, -jsat value
              If you play with an analog joystick, the ends can drift a little, and may not match
              in the +/- directions. joystick_saturation tells how far  along  an  axis  movement
              change  will be accepted before it reaches the maximum range. This option expects a
              float in the range of 0.0 to 1.0, where 0 is the center of the joystick  and  1  is
              the outer limit.  The default is 0.85.

       -natural, -nat
              Specifies whether to use a natural keyboard or not.

       -uimodekey, -umk
              Specifies the key used to toggle between full and partial UI mode.

       -keymap
              Enable keymap for non-QWERTY keyboards. Used in conjuction with -keymap_file.

       -keymap_file keymap_file
              Specifies  the full path to the keymap file to be used. Shipped keymap files lie in
              /usr/share/games/mame/keymaps.

       -joy_idx1 joystick

       -joy_idx2 joystick

       -joy_idx3 joystick

       -joy_idx4 joystick

       -joy_idx5 joystick

       -joy_idx6 joystick

       -joy_idx7 joystick

       -joy_idx8 joystick
              With these options you can assign a joystick to a specific index in MAME.  Even  if
              the kernel will list the joysticks in a different order on the next boot, MAME will
              still see the joystick as e.g. "Joystick 2". Use mame -v to see which joysticks are
              recognized.  Default is AUTO.

       -sixaxis
              Use special handling for PS3 Sixaxis controllers.

       -videodriver, -vd x11|directfb|auto
              SDL video driver to use; auto selects SDL default.

       -audiodriver, -ad alsa|arts|auto
              SDL audio driver to use; auto selects SDL default.

       -gl_lib alsa|arts|auto
              Alternative libGL.so to use; auto selects SDL default.

   Input automatic enable options
       -paddle_device, -paddle [none|keyboard|mouse|lightgun|joystick]

       -adstick_device, -adstick [none|keyboard|mouse|lightgun|joystick]

       -pedal_device, -pedal [none|keyboard|mouse|lightgun|joystick]

       -dial_device, -dial [none|keyboard|mouse|lightgun|joystick]

       -trackball_device, -trackball [none|keyboard|mouse|lightgun|joystick]

       -lightgun_device [none|keyboard|mouse|lightgun|joystick]

       -positional_device [none|keyboard|mouse|lightgun|joystick]

       -mouse_device [none|keyboard|mouse|lightgun|joystick]
              Each of these options controls autoenabling the mouse, or joystick depending on the
              presence of a particular class  of  analog  control  for  a  particular  game.  For
              example,  if  you specify the option -paddle mouse, then any game that has a paddle
              control will automatically enable mouse controls just  as  if  you  had  explicitly
              specified  -mouse.   Note  that  these  controls override the values of -[no]mouse,
              -[no]joystick, etc.

   Debugging options
       -[no]log
              Creates a file called error.log which contains all of  the  internal  log  messages
              generated by the MAME core and game drivers. The default is OFF (-nolog).

       -[no]verbose, -[no]v
              Displays  internal  diagnostic  information.  This  information  is very useful for
              debugging problems with your configuration. IMPORTANT: when reporting bugs,  please
              run  with  mame  -verbose and include the resulting information. The default is off
              (-noverbose).

       -update_in_pause
              Enables updating the screen bitmap while the game is paused.  This  is  useful  for
              debuggin in some scenarios (and gets in the way in others).

       -[no]debug, -[no]d
              Activates  the integrated debugger. By default, the debugger is entered by pressing
              the tilde (~) key during emulation. It is also entered immediately at startup.  The
              default is OFF (-nodebug).

       -debugscript filename
              Specifies  a  file that contains a list of debugger commands to execute immediately
              upon startup. The default is NULL (no commands).

       -debug_internal, -di
              Use the internal debugger for debugging.

       -[no]oslog
              Outputs the error.log data to the system debugger. This can be  used  at  the  same
              time  as  -log  to  output  the  log  data to both targets as well.  Default is OFF
              (-nooslog).

   Misc options
       -bios biosname
              Specifies the specific BIOS to use with the current game,  for  game  systems  that
              make  use  of  a BIOS. The -listxml output will list all of the possible BIOS names
              for a game. The default is 'default'.

       -[no]cheat, -[no]c
              Enables the reading of the cheat database, if present, and the Cheat  menu  in  the
              user interface. The  default is OFF (-nocheat).

       -[no]skip_gameinfo
              Forces  MAME  to  skip  displaying  the  game  info  screen.  The  default  is  OFF
              (-noskip_gameinfo).
