SYNOPSIS

9       mess system [media software] [options]
10

DESCRIPTION

12       MESS documents the hardware for a wide variety of (mostly vintage) com‐
13       puters, video game consoles, and calculators  through  software  emula‐
14       tion.  As  a nice side effect, MESS allows software and games for these
15       hardware platforms to run on modern PCs.
16

SOFTWARE

18       A software entry may be specified to attach an image file to  the  emu‐
19       lated  system. In such a case, the appropriate media switch is also re‐
20       quired:
21
22       -cart, -cart1
23              Cartrigde, used mainly by game consoles
24
25       -cass  Cassette (tape), widely used by old home computers
26
27       -flop, -flop1
28              Floppy disk
29
30       -cdrom CD-Rom
31

OPTIONS

33   Core commands
34       -help, -?
35              Displays current MESS version and copyright notice.
36
37       -validate, -valid
38              Performs internal validation on every driver in MESS.  Run  this
39              before  submitting  changes  to ensure that you haven't violated
40              any of the core system rules.
41
42   Configuration commands
43       -createconfig, -cc
44              Creates the default mess.ini file in the current directory.  All
45              the  configuration options (not commands) described below can be
46              permanently changed by editing this configuration file.
47
48       -showconfig, -sc
49              Displays the current configuration settings.
50
51       -showusage, -su
52              Displays a summary of all the command line options. For  options
53              that  are  not  mentioned  here,  the  short  summary  given  by
54              -showusage is usually sufficient.
55
56   Frontend commands
57       All the list commands below write info to the screen.  If you  wish  to
58       write  the  info  to a textfile instead, use redirection.  For example,
59       mess -listxml > ~/messlist.xml writes the full list of  supported  sys‐
60       tems to messlist.xml in your home directory.
61
62       -listxml, -lx [system|wildcard]
63              List comprehensive details for all of the supported systems. The
64              output is quite long, so it is usually better to  redirect  this
65              into  a  file.  The output is in XML format. By default all sys‐
66              tems are listed; however, you can limit this list by  specifying
67              a driver name or wildcard after the -listxml command.
68
69       -listfull, -ll [system|wildcard]
70              Displays  a list of system driver names and descriptions. By de‐
71              fault all systems are listed; however, you can limit  this  list
72              by specifying a driver name or wildcard after the -listfull com‐
73              mand.
74
75       -listsource, -ls [system|wildcard]
76              Displays a list of drivers and the names  of  the  source  files
77              their  system drivers live in. Useful for finding which driver a
78              system runs on in order to fix bugs. By default all systems  are
79              listed;  however, you can limit this list by specifying a driver
80              name or wildcard after the -listsource command.
81
82       -listclones, -lc [system|wildcard]
83              Displays a list of clones. By default  all  clones  are  listed;
84              however,  you can limit this list by specifying a driver name or
85              wildcard after the -listclones command.
86
87       -listbrothers, -lb [system|wildcard]
88              Displays a list of "brothers" or other drivers from same source‐
89              file.  By default all systems are listed; however, you can limit
90              this list by specifying a driver  name  or  wildcard  after  the
91              -listbrothers command.
92
93       -listcrc
94              Displays a full list of CRCs of all ROM images referenced by all
95              drivers within MESS code.
96
97       -listroms, -lr system
98              Displays a list of ROM images referenced by the  specified  sys‐
99              tem.
100
101       -listsamples system
102              Displays a list of samples referenced by the specified system.
103
104       -verifyroms [system|wildcard]
105              Checks for invalid or missing ROM images. By default all drivers
106              that have valid ZIP files or directories in  the  rom  path  are
107              verified;  however,  you  can  limit  this  list by specifying a
108              driver name or wildcard after the -verifyroms command.
109
110       -verifysamples [system|wildcard]
111              Checks for invalid or missing samples. By  default  all  drivers
112              that  have  valid ZIP files or directories in the samplepath are
113              verified; however, you can  limit  this  list  by  specifying  a
114              driver name or wildcard after the -verifyroms command.
115
116       -romident
117              Attempts  to  identify  ROM files, if they are known to MESS, in
118              the specified .zip file or directory. This command can  be  used
119              to try and identify ROM sets taken from unknown boards. On exit,
120              the errorlevel is returned as one of the following:
121              0  all files were identified
122              7  all files were identified except for some "non-ROM" files
123              8  some files were identified
124              9  no files were identified
125
126       -listdevices, -ld
127              Output the list of devices referenced by a given system  or  set

139
140       -verifysoftware, -vsoft [gamename|wildcard]
141              Checks for invalid or missing ROM images in your software lists.
142              By  default all drivers that have valid ZIP files or directories
143              in the rompath are verified; however, you can limit this list by
144              specifying a specific driver name or wildcard.
145
146       -getsoftlist, -glist
147              Retrieve software list by name.
148
149       -verifysoftlist, -vlist [softwarelistname]
150              Checks a specified software list for missing ROM images if files
151              exist for issued softwarelistname. By default, all drivers  that
152              have valid ZIP files or directories in the rompath are verified;
153              however, you can limit this list by specifying a specific  soft‐
154              warelistname (without .XML).
155

161
162   Configuration options
163       -[no]readconfig, -[no]rc
164              Enables  or  disables  the reading of the config files. When en‐
165              abled (which is the default), MESS reads  the  following  config
166              files in order:
167              1. mess.ini
168              the main configuration file
169              2. [driver].ini
170              based on the source file name of the system driver
171              3. debug.ini, if the debugger is enabled
172              4. vector.ini, for vector games only
173              5. [driver].ini
174              based on the source filename of the game driver
175              6. [parent].ini
176              for clones only, may be called recursively
177              4. [system].ini
178              note this sometimes resolves to the same of the source driver
179
180       The  settings  in  the later ini's override those in the earlier ini's.
181       The default is ON (-readconfig).
182
183       -[no]writeconfig, -[no]wc
184              Write configuration to [driver].ini on  exit.   Default  is  OFF
185              (-nowriteconfig).
186
187   Search path options
188       Be  careful  to  use  the  path, directory and file options in mess.ini
189       ONLY. Otherwise, the outcome may be unpredictable  and  not  consistent
190       across releases.
191
192       -rompath, -rp, -biospath, -bp pathname
193              Specifies  a list of paths within which to find ROM or hard disk
194              images.  Multiple paths can be specified by separating them with
195              semicolons.   The default is 'roms' (that is, a directory 'roms'

206              Multiple paths can be specified by separating  them  with  semi‐
207              colons. The default is 'samples' (that is, a directory 'samples'
208              in the same directory as the MESS executable).
209
210       -artpath, -artwork_directory pathname
211              Specifies a list of paths within which to  find  artwork  files.
212              Multiple  paths  can  be specified by separating them with semi‐
213              colons. The default is 'artwork' (that is, a directory 'artwork'
214              in the same directory as the MESS executable).
215
216       -ctrlrpath, -ctrlr_directory pathname
217              Specifies  a  list of paths within which to find controller-spe‐
218              cific configuration files. Multiple paths can  be  specified  by
219              separating  them  with  semicolons. The default is 'ctrlr' (that
220              is, a directory 'ctrlr' in the same directory as the  MESS  exe‐
221              cutable).
222
223       -inipath pathname
224              Specifies  a list of paths within which to find .ini files. Mul‐
225              tiple paths can be specified by separating them with semicolons.
226              The default is '/etc/mess'.
227
228       -fontpath pathname
229              Specifies  a list of paths within which to find .bdf font files.
230              Multiple paths can be specified by separating  them  with  semi‐
231              colons.  The  default is '.' (that is, search in the same direc‐
232              tory as the MESS executable).
233
234       -cheatpath pathname
235              Specifies a list of paths within which to find cheat files. Mul‐
236              tiple paths can be specified by separating them with semicolons.
237              The default is 'cheat' (that is, a directory 'cheat' in the same
238              directory as the MESS executable).
239
240       -crosshairpath pathname
241              Specifies  a list of paths within which to find crosshair files.
242              Multiple paths can be specified by separating  them  with  semi‐

244              'crosshair' in the same directory as the MESS  executable).   If
245              the  Crosshair is set to default in the menu, MESS will look for
246              system/cross#.png and then cross#.png  in  the  specified  path,
247              where  #  is  the  player  number.   Failing that, MESS will use
248              built-in default crosshairs.
249
250       -pluginspath pathname
251              Specifies a single path within which to find  plugins.  The  de‐
252              fault  is  'plugins' (that is, a directory 'plugins' in the same
253              directory as the MESS executable).
254
255       -languagepath pathname
256              Specifies a single path within which to find language files. The
257              default  is  'language'  (that is, a directory 'language' in the
258              same directory as the MESS executable).
259
260   Output Directory Options
261       -cfg_directory pathname
262              Specifies a  single  directory  where  configuration  files  are
263              stored.   Configuration  files  store user configurable settings
264              that are read at startup and written when MESS  exits.  The  de‐
265              fault is 'cfg' (that is, a directory 'cfg' in the same directory
266              as the MESS executable). If this directory does  not  exist,  it
267              will be automatically created.
268
269       -nvram_directory pathname
270              Specifies a single directory where NVRAM files are stored. NVRAM
271              files store the contents of EEPROM and non-volatile RAM  (NVRAM)
272              for  systems which used this type of hardware. This data is read
273              at startup and written when MESS exits. The default  is  'nvram'
274              (that  is, a directory 'nvram' in the same directory as the MESS
275              executable). If this directory does not exist, it will be  auto‐
276              matically created.
277
278       -input_directory pathname
279              Specifies  a  single  directory  where input recording files are
280              stored.  Input recordings are created via the -record option and
281              played back via the -playback option. The default is 'inp' (that
282              is, a directory 'inp' in the same directory  as  the  MESS  exe‐
283              cutable). If this directory does not exist, it will be automati‐
284              cally created.
285
286       -state_directory pathname
287              Specifies a single directory where save state files are  stored.
288              Save  state files are read and written either upon user request,
289              or when using the -autosave option. The default is  'sta'  (that
290              is,  a  directory  'sta'  in the same directory as the MESS exe‐
291              cutable). If this directory does not exist, it will be automati‐
292              cally created.
293
294       -snapshot_directory pathname
295              Specifies  a single directory where screen snapshots are stored,
296              when requested by the user. The default is 'snap'  (that  is,  a
297              directory  'snap' in the same directory as the MESS executable).
298              If this directory does not exist, it will be automatically  cre‐
299              ated.
300
301       -diff_directory pathname
302              Specifies a single directory where hard drive differencing files
303              are stored. Hard drive differencing files store any data that is
304              written  back  to  a  hard  disk image, in order to preserve the
305              original image. The differencing files are  created  at  startup
306              when  a  system  with  a  hard disk image. The default is 'diff'
307              (that is, a directory 'diff' in the same directory as  the  MESS
308              executable).  If this directory does not exist, it will be auto‐
309              matically created.
310
311       -comment_directory pathname
312              Specifies a single directory where debugger  comment  files  are
313              stored.  Debugger comment files are written by the debugger when
314              comments are added to the disassembly for a system. The  default
315              is  'comments'  (that is, a directory 'comments' in the same di‐
316              rectory as the MESS executable).  If this directory does not ex‐
317              ist, it will be automatically created.
318
319   State/playback options
320       -state slot
321              Immediately  after starting the specified system, will cause the
322              save state in the specified slot to be loaded.
323
324       -[no]autosave
325              When enabled, automatically creates a save state file when exit‐
326              ing  MESS  and  automatically  attempts  to reload it when later
327              starting MESS with the same system. This only works for  systems
328              that have explicitly enabled save state support in their driver.
329              The default is OFF (-noautosave).
330
331       -playback, -pb filename
332              Specifies a file from which to play back a series of system  in‐
333              puts.  This  feature does not work reliably for all systems, but
334              can be used to watch a previously recorded system  session  from
335              start  to finish. In order to make things consistent, you should
336              only record and playback with all  configuration  (.cfg),  NVRAM
337              (.nv),  and  memory  card files deleted. The default is NULL (no
338              playback).
339
340       -[no]exit_after_playback
341              If play back is enabled (see -playback option) the program exits
342              when end of file is reached. Otherwise the machine will continue
343              to run.  Default is OFF (-noexit_after_playback).
344
345       -record, -rec filename
346              Specifies a file to record all input from a system session. This
347              can  be used to record a system session for later playback. This
348              feature does not work reliably for all systems, but can be  used
349              to watch a previously recorded system session from start to fin‐
350              ish. In order to make things consistent, you should only  record
351              and  playback  with  all  configuration (.cfg), NVRAM (.nv), and
352              memory card files deleted. The default is NULL (no recording).
353
354       -[no]record_timecode
355              Specify whether to create a timecode file. It  contains  a  line
356              with  elapsed  times on each press of timecode shortcut key (de‐
357              fault is F12).  This option works only when  recording  mode  is
358              enabled (-record option).  The file is saved on inp folder.  De‐
359              fault is OFF (-norecord_timecode).
360
361       -mngwrite filename
362              Writes each video frame to the given file in MNG format, produc‐
363              ing  an  animation  of  the system session.  Note that -mngwrite
364              only writes video frames; it does not save any audio  data.  Use
365              -wavwrite for that, and reassemble the audio/video using offline
366              tools. The default is NULL (no recording).
367
368       -aviwrite filename
369              Stream video and sound data to the given  file  in  AVI  format,
370              producing  an  animation  of  the  system  session complete with
371              sound. The default is NULL (no recording).
372
373       -wavwrite filename
374              Writes the final mixer output to the given file in  WAV  format,
375              producing an audio recording of the system session.  The default
376              is NULL (no recording).
377
378       -snapname string
379              Describes how MESS should name files for snapshots. string  pro‐
380              vides a template that is used to generate a filename. Three sim‐
381              ple substitutions are provided: the / character  represents  the
382              path  separator  on any target platform (even Windows); the lit‐
383              eral %g represents the driver name of the  current  system;  and
384              the  literal %i represents an incrementing index. If %i is omit‐
385              ted, then each snapshot taken will overwrite the  previous  one;
386              otherwise,  MESS  will  find the next empty value for %i and use
387              that for a filename. The default is %g/%i, which creates a sepa‐
388              rate  folder  for  each system, and names the snapshots under it
389              starting with 0000 and increasing from there. In addition to the
390              above,  for  drivers using different media, like carts or floppy
391              disks, you can also use the %d_[media] indicator.  Replace  [me‐
392              dia]  with  the media switch you want to use. A few examples: if
393              you use mess nes -cart robby -snapname %g/%d_cart snapshots will
394              be  saved  as  snaps/nes/robby.png;  if  you use mess c64 -flop1
395              robby  -snapname  %g/%d_flop1/%i  snapshots  will  be  saved  as
396              snaps/c64/robby/0000.png.
397
398       -snapsize widthxheight
399              Hard-codes  the  size  for snapshots and movie recording. By de‐
400              fault, MESS will create snapshots at the system's current  reso‐
401              lution  in  raw  pixels,  and will create movies at the system's
402              starting resolution in raw pixels. If you specify  this  option,
403              then  MESS  will  create  both  snapshots and movies at the size
404              specified, and will bilinear filter the result. Note  that  this
405              size  does  not automatically rotate if the system is vertically
406              oriented. The default is 'auto'.
407
408       -snapview internal|auto|viewname
409              Specifies the view to use when rendering snapshots  and  movies.
410              By  default, both use a special 'internal' view, which renders a
411              separate snapshot per screen or renders movies only of the first
412              screen. By specifying this option, you can override this default
413              behavior and select a single view that will apply to  all  snap‐
414              shots and movies.  Note that viewname does not need to be a per‐
415              fect match; rather, it will select the  first  view  whose  name
416              matches  all  the characters specified by viewname. For example,
417              -snapview native will  match  the  "Native  (15:14)"  view  even
418              though  it is not a perfect match.  viewname can also be 'auto',
419              which selects the first view with all screens present.  The  de‐
420              fault value is 'internal'.
421
422       -[no]snapbilinear
423              Specify  whether  snapshot/movie  should have bilinear filtering
424              applied.  Default is ON (-snapbilinear).
425
426       -statename string
427              Describes how MESS should store save state  files,  relative  to
428              the  state_directory  path.  string  provides a template that is
429              used to generate a relative path. Two simple  substitutions  are
430              provided:  the  / character represents the path separator on any
431              target platform (even Windows); the literal  %g  represents  the
432              driver name of the current game. The default is '%g', which cre‐
433              ates a separate folder for each game. In addition to the  above,
434              for  drivers  using different media, like carts or floppy disks,
435              you can also use the %d_[media] indicator. Replace [media]  with
436              the  media  switch  you  want to use. A few examples: if you use
437              mess nes -cart robby -statename %g/%d_cart save states  will  be
438              stored  inside  sta/nes/robby/; if you use mess c64 -flop1 robby
439              -statename  %g/%d_flop1  save  states  will  be  stored   inside
440              sta/c64/robby/.
441
442       -[no]burnin
443              Tracks  brightness  of  the screen during play and at the end of
444              emulation generates a PNG that can be used to  simulate  burn-in
445              effects on other systems. The resulting PNG is created such that
446              the least-used areas  of  the  screen  are  fully  white  (since
447              burned-in  areas  are darker, all other areas of the screen must
448              be lightened a touch).  The intention is that this  PNG  can  be
449              loaded  via an artwork file with a low alpha (e.g, 0.1-0.2 seems
450              to work well) and blended over the entire screen. The PNG  files
451              are    saved    in   the   snap   directory   under   the   sys‐
452              tem/burnin-<screen.name>.png. The default is OFF (-noburnin).
453
454   Performance options
455       -[no]autoframeskip, -[no]afs
456              Automatically determines the frameskip level while you're  play‐
457              ing  the system, adjusting it constantly in a frantic attempt to
458              keep the system running at full speed. Turning this on overrides
459              the  value you have set for -frameskip below. The default is OFF
460              (-noautoframeskip).
461
462       -frameskip, -fs value
463              Specifies the frameskip value (autoframeskip must be  disabled).
464              This  is  the number of frames out of every 12 to drop when run‐
465              ning. For example, if you say -frameskip 2, then MESS will  dis‐
466              play  10  out  of every 12 frames. By skipping those frames, you
467              may be able to get full speed in a  system  that  requires  more
468              horsepower than your computer has. The default value is 0, which
469              skips no frames.
470
471       -seconds_to_run, -str value
472              This option can be used for benchmarking and automated  testing.
473              It tells MESS to stop execution after a fixed number of seconds.
474              By combining this with a fixed set of  other  command  line  op‐
475              tions,  you can set up a consistent environment for benchmarking
476              MESS performance. In addition, upon exit, the -str  option  will
477              write a screenshot called final.png to the system's snapshot di‐
478              rectory.
479
480       -[no]throttle
481              Configures the default thottling setting. When throttling is on,
482              MESS  attempts  to  keep  the system running at the system's in‐
483              tended speed. When throttling is off, MESS runs  the  system  as
484              fast  as  it can. Note that the fastest speed is more often than
485              not limited by your graphics card, especially for older systems.
486              The default is ON (-throttle).
487
488       -[no]sleep
489              Allows  MESS  to  give time back to the system when running with
490              -throttle.  This allows other programs to have  some  CPU  time,
491              assuming  that  the  system  isn't  taxing  100% of your CPU re‐
492              sources. This option can potentially cause  hiccups  in  perfor‐
493              mance  if  other demanding programs are running.  The default is
494              ON (-sleep).
495
496       -speed value
497              Controls the speed of gameplay, relative  to  realtime;  smaller
498              numbers are slower. Default is 1.00.
499
500       -[no]refreshspeed, -[no]rs
501              Automatically adjusts the -speed parameter to keep the effective
502              refresh rate below that of the lowest screen refresh rate.   De‐
503              fault is OFF (-norefreshspeed).
504
505       -numprocessors, -np value
506              Set  number  of processors; this overrides the number the system
507              reports.
508
509       -bench value
510              Benchmark for the given  number  of  emulated  seconds;  implies
511              -video none -sound none -nothrottle.
512
513       -[no]sdlvideofps
514              Show SDL video performance. Default is OFF (-nosdlvideofps).
515
516   Rotation options
517       -[no]rotate
518              Rotate  the  system to match its normal state (horizontal/verti‐
519              cal). This ensures that both vertically  and  horizontally  ori‐
520              ented  systems show up correctly without the need to rotate your
521              monitor. If you want to keep the system displaying 'raw' on  the
522              screen  the  way the actual machine would have, turn this option
523              off. The default is ON (-rotate).
524
525       -[no]ror -[no]rol
526              Rotate the system  screen  to  the  right  (clockwise)  or  left
527              (counter-clockwise) relative to either its normal state (if -ro‐
528              tate is specified) or its native state (if -norotate  is  speci‐
529              fied).  Default for both is OFF (-noror -norol).
530
531       -[no]autoror -[no]autorol
532              These  options  are  designed for use with pivoting screens that
533              only pivot in a single direction. If  your  screen  only  pivots
534              clockwise,  use -autorol to ensure that the system will fill the
535              screen either horizontally or vertically in one  of  the  direc‐
536              tions you can handle.  If your screen only pivots counter-clock‐
537              wise, use -autoror.  Default for both is OFF (-noautoror  -noau‐
538              torol).
539
540       -[no]flipx -[no]flipy
541              Flip  (mirror) the system screen either horizontally (-flipx) or
542              vertically (-flipy). The flips are applied after the -rotate and
543              -ror/-rol   options  are  applied.   Default  for  both  is  OFF
544              (-noflipx -noflipy).
545
546   Artwork options
547       -[no]artwork_crop, -[no]artcrop
548              Enable cropping of artwork to the system screen area only.  This
549              option  can also be controlled via the Video Options menu in the
550              user interface. The default is OFF (-noartwork_crop).
551
552       -[no]use_backdrops, -[no]backdrop
553              Enables/disables the display of backdrops.  The  default  is  ON
554              (-use_backdrops).
555
556       -[no]use_overlays, -[no]overlay
557              Enables/disables  the  display  of  overlays.  The default is ON
558              (-use_overlays).
559
560       -[no]use_bezels, -[no]bezel
561              Enables/disables the  display  of  bezels.  The  default  is  ON
562              (-use_bezels).
563
564       -[no]use_cpanels, -[no]cpanel
565              Enables/disables  the  display  of  cpanels.  The  default is ON
566              (-use_bezels).
567
568       -[no]use_marquees, -[no]marquee
569              Enables/disables the display of  marquees.  The  default  is  ON
570              (-use_bezels).
571
572   Screen options
573       -brightness value
574              Controls  the  default brightness, or black level, of the system
575              screens.  This option does not affect the artwork or other parts
576              of the display.  Using the MESS UI, you can individually set the
577              brightness for each system screen; this option controls the ini‐
578              tial value for all visible system screens. The standard value is
579              1.0. Selecting lower values (down to 0.1) will produce  a  dark‐
580              ened  display,  while  selecting  higher values (up to 2.0) will
581              give a brighter display. The default is 1.0.
582
583       -contrast value
584              Controls the contrast, or white level, of  the  system  screens.
585              This  option  does  not affect the artwork or other parts of the
586              display. Using the MESS UI, you can individually  set  the  con‐
587              trast  for  each system screen; this option controls the initial
588              value for all visible system screens. The standard value is 1.0.
589              Selecting  lower values (down to 0.1) will produce a dimmer dis‐
590              play, while selecting higher values (up to 2.0) will give a more
591              saturated display. The default is 1.0.
592
593       -gamma value
594              Controls the gamma, which produces a potentially nonlinear black
595              to white ramp, for the system screens. This option does not  af‐
596              fect  the  artwork or other parts of the display. Using the MESS
597              UI, you can individually set the gamma for each  system  screen;
598              this  option  controls  the initial value for all visible system
599              screens. The standard value is 1.0, which gives  a  linear  ramp
600              from  black  to white. Selecting lower values (down to 0.1) will
601              increase the nonlinearity toward black, while  selecting  higher
602              values  (up to 3.0) will push the nonlinearity toward white. The
603              default is 1.0.
604
605       -pause_brightness value
606              This controls the brightness level when MESS is paused. The  de‐
607              fault value is 0.65.
608
609       -effect [none|filename[.png]]
610              Name of a PNG file to use for visual effects, or 'none'. Default
611              is 'none'.
612
613   Vector rendering options
614       -beam_width_min value
615
616       -beam_width_max value
617              Sets the minimum and maximum width of the  vectors.  This  is  a
618              scaling  factor  against the standard vector width, which is in‐
619              terpolated between minimum and maximum according to  the  beam's
620              intensity.  A  value  of  1.0  will keep the default vector line
621              width. Smaller values will reduce the width, and  larger  values
622              will increase the width. The default is 1.0.
623
624       -beam_intensity_weight value
625              Applies  an  exponential  weight to the minimum and maximum beam
626              width. For positive values the interpolated scaling factor  will
627              affect  lines  with  higher intensity more than lines with lower
628              intensity. The default is 0.0.
629
630       -flicker value
631              Simulates a vector "flicker" effect, similar to a vector monitor
632              that  needs adjustment. This option requires a float argument in
633              the range of 0.00-100.00 (0=none, 100=maximum). The  default  is
634              0.
635
636   Video options
637       -video [soft|opengl|bgfx|none]
638              Specifies which video subsystem to use for drawing:
639              soft  uses software rendering, which is slower but more compati‐
640              ble.
641              opengl  uses OpenGL and your graphics accelerator  to  speed  up
642              many  aspects  of  drawing  MAME  including compositing artwork,
643              overlays, and bezels, as well as stretching  the  image  to  fit
644              your screen.
645              bgfx  uses the bgfx renderer which supports portable shaders and
646              multiple graphics APIs including OpenGL, OpenGL ES and DirectX.
647              none  does no drawing and is intended for CPU benchmarking.
648              Default is 'soft' on Linux or 'opengl' on macOS.
649
650       -numscreens [1-4]
651              Number of screens to create; usually, you want just one. Default
652              is '1'.
653
654       -[no]window, -[no]w
655              Run MESS in either full screen or a window. This is a fully-fea‐
656              tured window mode where the window resizes as necessary to track
657              what  the system does.  And you can resize it yourself with your
658              OS's standard window controls.  The default is OFF (-nowindow).
659
660       -[no]maximize, -[no]max
661              Controls initial window size in windowed mode. If it is set  on,
662              the  window  will initially be set to the maximum supported size
663              when you start MESS. If it is turned off, the window will  start
664              out  at the smallest supported size. This option only has an ef‐
665              fect when the -window option is used. The default is ON  (-maxi‐
666              mize).
667
668       -[no]keepaspect, -[no]ka
669              Forces the correct aspect ratio. This means when you're resizing
670              the window in windowed mode the actual system image will  resize
671              in  discrete  steps  to  maintain the proper shape of the system
672              graphics. If you turn this off you can resize the window to any‐
673              thing you like and get funny squishing and stretching.  The same
674              applies for full-screen. Default is ON (-keepaspect).
675
676       -[no]unevenstretch, -[no]ues
677              Allow non-integer stretch factors.  Video  purists  should  stay
678              far,  far  away  from  this  option, while everyone else will be
679              happy to know that it lets  you  fill  the  screen  properly  in
680              full-screen mode. Default is ON (-unevenstretch).
681
682       -[no]unevenstretchx, -[no]uesx
683              Act as -[no]unevenstretch on horizontal basis only.
684
685       -[no]intoverscan, -[no]ios
686              Allow overscan on integer scaled targets.
687
688       -intscalex, -sx
689              Set horizontal integer scale factor.
690
691       -intscaley, -sy
692              Set vertical integer scale factor.
693
694       -[no]centerh
695              Center  horizontally  within the view area. Default is ON (-cen‐
696              terh).
697
698       -[no]centerv
699              Center vertically within the view area.  Default  is  ON  (-cen‐
700              terv).
701
702       -[no]waitvsync, -[no]vs
703              Enable  waiting for the start of VBLANK before flipping screens;
704              reduces tearing effects. Default is OFF (-nowaitvsync).
705
706       -[no]syncrefresh, -[no]srf
707              Enable using the start of VBLANK for throttling instead  of  the
708              game time.  Default is OFF (-nosyncrefresh).
709
710   Software video rendering subsystem options
711       NOTE:  All  the  options  in this group are available only with softare
712       video rendering subsystem, i.e -video soft.
713
714       -prescale [value]
715              Scale screen rendering by this amount in software. Default is 1.
716
717       -scalemode, -sm [none|async|yv12|yuy2|yv12x2|yuy2x2]
718              Hardware scaling mode.
719              none    use software rendering.
720              async   async overlay.
721              yv12    yv12 overlay.
722              yuy2    yuy2 overlay.
723              yv12x2  yv12 overlay using x2 prescaling.
724              yuy2x2  yuy2 overlay using x2 prescaling.
725              Default is NONE.
726
727   OpenGL video rendering subsystem options
728       NOTE: All the options in this group  are  available  only  with  OpenGL
729       video rendering subsystem, i.e -video opengl.
730
731       -[no]filter, -[no]glfilter, -[no]flt
732              Enable bilinear filtering on screen output. Default is ON (-fil‐
733              ter).
734
735       -prescale [value]
736              Scale screen rendering by this amount in software. Default is 1.
737
738       -[no]gl_forcepow2texture
739              Force power of two textures. Default is OFF (-nogl_forcepow2tex‐
740              ture).
741
742       -[no]gl_notexturerect
743              Don't  use  OpenGL GL_ARB_texture_rectangle. Turn off if corrup‐
744              tion occurs in OpenGL mode, at cost of  some  performance  loss.
745              Default is ON (-gl_notexturerect).
746
747       -[no]gl_vbo
748              Enable  OpenGL  VBO,  if  available, for a performance increase.
749              Turn off if corruption occurs. Default is ON (-gl_vbo).
750
751       -[no]gl_pbo
752              Enable OpenGL PBO, if available,  for  a  performance  increase.
753              Turn off if corruption occurs. Default is ON (-gl_pbo).
754
755       -[no]gl_glsl
756              Enable  OpenGL  GLSL,  if available, for a performance increase.
757              Default is OFF (-nogl_glsl).
758
759       -gl_glsl_filter value
760              Enable OpenGL GLSL filtering instead of  FF  filtering  0=plain,
761              1=bilinear.  Default is 1: bilinear.
762
763       -glsl_shader_mame[0-9]
764              Preferred  custom  OpenGL GLSL shader set mame bitmap (from 0 to
765              9).
766
767       -glsl_shader_screen[0-9]
768              Preferred custom OpenGL GLSL shader screen bitmap (from 0 to 9).
769
770       -gl_glsl_vid_attr
771              Enable OpenGL GLSL handling of brightness and  contrast.  Better
772              RGB system performance for free. Default is ON.
773
774       -screen
775              Explicit  name  for  all screens; 'auto' here will try to make a
776              best guess.
777
778       -aspect, -screen_aspect
779              Aspect ratio for all screens; 'auto' here will  try  to  make  a
780              best guess.
781
782       -resolution, -r
783              Preferred   resolution   for  all  screens;  format  is  widthx‐
784              height[@refreshrate] or 'auto'.
785
786       -view  Preferred view for all screens
787
788       -screen[0-3]
789              Explicit name of the  first|second|third|fourth  screen;  'auto'
790              here will try to make a best guess.
791
792       -aspect[0-3]
793              Aspect  ratio  of  the  first|second|third|fourth screen; 'auto'
794              here will try to make a best guess.
795
796       -resolution[0-3], -r[0-3]
797              Preferred resolution for the  first|second|third|fourth  screen;
798              format is widthxheight[@refreshrate] or 'auto'.
799
800       -view[0-3]
801              Preferred view for the first|second|third|fourth screen.
802
803   BGFX post-processing options
804       NOTE:  All the options in this group are available only when BGFX video
805       post-processing is enabled, i.e -video bgfx.  For  full  info  on  BGFX
806       please visit official MAME documentation page:
807       http://docs.mamedev.org/advanced/bgfx.html
808
809       -bgfx_path pathname
810              This is where your BGFX shader files are stored.  The default is
811              'bgfx' (that is, a directory "bgfx" in the same directory as the
812              MESS executable).
813
814       -bgfx_backend auto|opengl
815              Selects  a  rendering  backend  for  BGFX to use. The default is
816              'auto', which will let MESS choose the best selection for you.
817
818       -bgfx_debug
819              Enables BGFX debugging features. Most users will not need to use
820              this.
821
822       -bgfx_screen_chains default|unfiltered|hlsl[,...]
823              This  dictates how to handle BGFX rendering on a per-display ba‐
824              sis.  For each display specify one of the possible choices:
825              default     default bilinear filterered output
826              unfiltered  nearest neighbor unfiltered output
827              hlsl        HLSL display simulation through shaders
828              Separate directives for each window with a  comma  (,)  and  for
829              each  physical screen with a colon (:). For example, for an emu‐
830              lated game with 3 displays emulated on 3 windows on  your  moni‐
831              tor, -bgfx_screen_chains default,unfiltered,default specifies to
832              apply default filter on what is been rendered on the  first  and
833              third  window  and leave the content of the second window unfil‐
834              tered.
835
836       -bgfx_shadow_mask filename
837              This specifies the shadow  mask  effect  PNG  file.  Default  is
838              'slot-mask.png'.
839
840       -bgfx_avi_name filename
841              This specifies a filename for BGFX output logging.
842
843   Full screen options
844       -[no]switchres
845              Affects full screen mode only. Chooses if MESS can try to change
846              the screen resolution (color depth is normally left alone)  when
847              in  full-screen  mode.  If it's off, you always get your desktop
848              resolution in full-screen mode (which can be useful  for  LCDs).
849              Default is OFF (-noswitchres).
850
851       -[no]useallheads
852              Split full screen image across monitors. Default is OFF (-nouse‐
853              allhead).
854
855   Sound options
856       -sound [sdl|portaudio|coreaudio|dsound|xaudio2|none]
857              Specifies which sound subsystem to use for audio output:
858              sdl  uses the Simple DirectMedia Layer audio output system  (not
859              available on Windows by default).
860              portaudio  uses the PortAudio library which supports low-latency
861              output and multiple audio APIs.
862              coreaudio  uses the Core Audio API  which  supports  low-latency
863              output and AudioUnit effects (only available on macOS).
864              dsound  uses the DirectSound API (only available on Windows).
865              xaudio2   uses the XAudio2 API which supports low-latency output
866              (only available on Windows).
867              none  produces no audio output.
868              Default is 'dsound' on Windows, 'coreaudio' on macOS or 'sdl' on
869              other platforms.
870
871       -samplerate, -sr value
872              Sets  the  audio  sample rate. Smaller values (e.g. 11025) cause
873              lower audio quality but faster emulation  speed.  Higher  values
874              (e.g.  48000)  cause  higher  audio quality but slower emulation
875              speed. The default is 48000.
876
877       -[no]samples
878              Use samples if available. The default is ON (-samples).
879
880       -[no]compressor
881              Enable audio compressor. It temporarily reduces the overall vol‐
882              ume  when  the  audio  output  is  overdriven. The default is ON
883              (-compressor).
884
885       -volume, -vol value
886              Sets the startup volume. It can later be changed with  the  user
887              interface  (see  Keys  section). The volume is an attenuation in
888              dB: for example, '-volume -12' will start  with  -12dB  attenua‐
889              tion.  The default is 0.
890
891       -audio_latency value
892              This controls the amount of latency built into the audio stream‐
893              ing.  The exact behavior depends on the  selected  audio  output
894              module (see the -sound option).  Smaller values provide less au‐
895              dio delay while requiring  better  system  performance.   Higher
896              values increase audio delay but may help avoid buffer under-runs
897              and audio interruptions.  The default is 1.
898
899   Input options
900       -[no]coin_lockout, -[no]coinlock
901              Enables simulation of the "coin lockout" feature that is  imple‐
902              mented  on a number of arcade game PCBs. It was up to the opera‐
903              tor whether or not the coin lockout outputs were  actually  con‐
904              nected  to the coin mechanisms. If this feature is enabled, then
905              attempts to enter a coin while the lockout is active  will  fail
906              and  will display a popup message in the user interface. If this
907              feature is disabled, the coin lockout signal  will  be  ignored.
908              The default is ON (-coin_lockout).
909
910       -ctrlr controller
911              Enables support for special controllers. Configuration files are
912              loaded from the ctrlrpath. They are in the same  format  as  the
913              .cfg  files  that are saved, but only control configuration data
914              is read from the file. The default is NULL (no controller file).
915
916       -[no]mouse
917              Controls whether or not MESS looks for  a  mouse  controller  to
918              use.  Note  that in many cases, lightguns are treated as mice by
919              the operating system, so you may need to enable this  to  enable
920              lightgun  support. When this is enabled, you will not be able to
921              use your mouse while running MESS. If you want to get control of
922              your  computer back, you will need to either pause MESS or quit.
923              The default is OFF (-nomouse).
924
925       -[no]joystick, -[no]joy
926              Controls whether or not MESS  looks  for  joystick/gamepad  con‐
927              trollers.  The default is ON (-joystick).
928
929       -[no]lightgun, -[no]gun
930              Controls  whether or not MESS makes use of lightgun controllers.
931              Note that most lightguns map to the mouse,  so  using  -lightgun
932              and  -mouse together may produce strange results. The default is
933              OFF (-nolightgun).
934
935       -[no]multikeyboard, -[no]multikey
936              Determines whether MESS  differentiates  between  multiple  key‐
937              boards.   Some systems may report more than one keyboard; by de‐
938              fault, the data from all of these keyboards is combined so  that
939              it looks like a single keyboard. Turning this option on will en‐
940              able MESS to report keypresses on different  keyboards  indepen‐
941              dently. The default is OFF (-nomultikeyboard).
942
943       -[no]multimouse
944              Determines  whether  MESS  differentiates between multiple mice.
945              Some systems may report more than one mouse device; by  default,
946              the  data  from  all  of these mice is combined so that it looks
947              like a single mouse. Turning this option on will enable MESS  to
948              report mouse movement and button presses on different mice inde‐
949              pendently. The default is OFF (-nomultimouse).
950
951       -[no]steadykey, -[no]steady
952              Some systems require two or more buttons to be  pressed  at  ex‐
953              actly the same time to make special moves. Due to limitations in
954              the PC keyboard hardware, it can be difficult or even impossible
955              to  accomplish  that  using the standard keyboard handling. This
956              option selects a different handling that makes it easier to reg‐
957              ister  simultaneous  button presses, but has the disadvantage of
958              making controls less  responsive.  The  default  is  OFF  (-nos‐
959              teadykey).
960
961       -[no]ui_active
962              Enable  MESS  user  interface  on  top  of emulated keyboard (if
963              present).  User interface may be  toggled  during  execution  by
964              pressing  the  key  defined  with  -ui_modekey.   Default is OFF
965              (-noui_active).
966
967       -[no]offscreen_reload, -[no]reload
968              Controls whether or not MESS treats a second button input from a
969              lightgun  as a reload signal. In this case, MESS will report the
970              gun's position as (0,MAX) with the trigger held, which is equiv‐
971              alent  to  an  offscreen reload. This is only needed for systems
972              that required you to shoot offscreen to reload, and then only if
973              your gun does not support off screen reloads. The default is OFF
974              (-nooffscreen_reload).
975
976       -joystick_map, -joymap map
977              Controls how joystick values map to digital  joystick  controls.
978              See  /usr/share/doc/mame-common/config.txt  for  full details on
979              joymap format.
980
981       -joystick_deadzone, -joy_deadzone, -jdz value
982              If you play with an analog joystick, the center can drift a lit‐
983              tle.   joystick_deadzone  tells  how  far along an axis you must
984              move before the axis starts to change.  This  option  expects  a
985              float  in  the range of 0.0 to 1.0. Where 0 is the center of the
986              joystick and 1 is the outer limit. The default is 0.3.
987
988       -joystick_saturation, -joy_saturation, -jsat value
989              If you play with an analog joystick, the ends can drift  a  lit‐
990              tle,  and  may not match in the +/- directions. joystick_satura‐
991              tion tells how far along an axis movement  change  will  be  ac‐
992              cepted  before it reaches the maximum range. This option expects
993              a float in the range of 0.0 to 1.0, where 0 is the center of the
994              joystick and 1 is the outer limit.  The default is 0.85.
995
996       -[no]natural, -[no]nat
997              Allows user to specify whether or not to use a natural keyboard.
998              This allows you to start your game or system in a 'native' mode,
999              depending  on  your  region, allowing compatibility for non-"QW‐
1000              ERTY" style keyboards.  The default is OFF (-nonatural).
1001
1002       -[no]joystick_contradictory, -[no]joy_contradictory
1003              Enable contradictory direction digital  joystick  input  at  the
1004              same time.  Default is OFF (-nojoystick_contradictory).

1028
1029       -[no]keymap
1030              Enable keymap for non-QWERTY keyboards. Used in conjunction with
1031              -keymap_file. Default is OFF (-nokeymap).
1032
1033       -keymap_file keymap_file
1034              Specifies  the  full  path  to the keymap file to be used. A few
1035              keymap files are available in /usr/share/games/mess/keymaps.
1036
1037       -joy_idx[0-8] joystick
1038              With these options you can assign a joystick to a specific index
1039              in MESS. Even if the kernel will list the joysticks in a differ‐
1040              ent order on the next boot, MESS will still see the joystick  as
1041              e.g. "Joystick 2". Use mame -v to see which joysticks are recog‐
1042              nized.  Default is 'auto'.
1043
1044       -[no]sixaxis
1045              Use special handling for PS3 Sixaxis  controllers.   Default  is
1046              OFF (-nosixaxis).

1073       -positional_device [none|keyboard|mouse|lightgun|joystick]
1074
1075       -mouse_device [none|keyboard|mouse|lightgun|joystick]
1076              Each of these options controls automatically enabling the mouse,
1077              or joystick depending on the presence of a particular  class  of
1078              analog  control  for  a  particular  system. For example, if you
1079              specify the option -paddle mouse, then any  system  that  has  a
1080              paddle  control will automatically enable mouse controls just as
1081              if you had explicitly specified -mouse.  Note  that  these  con‐
1082              trols override the values of -[no]mouse, -[no]joystick, etc.
1083

1158              fall back to its built-in UI font. On  some  platforms  fontname
1159              can  be  a  system font name instead of a BDF font file. The de‐
1160              fault is 'default' (use the OSD-determined default font).
