-.B \-state \fIslot
-Immediately after starting the specified system, will cause the save

-.TP
-.B \-[no]autosave
-When enabled, automatically creates a save state file when exiting MESS
-and automatically attempts to reload it when later starting MESS with
-the same system. This only works for systems that have explicitly enabled
-save state support in their driver. The default is OFF (\-noautosave).
-.TP
-.B \-playback, \-pb \fIfilename
-Specifies a file from which to play back a series of system inputs. This
-feature does not work reliably for all systems, but can be used to watch
-a previously recorded system 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).
-.TP
-.B \-[no]exit_after_playback
-If play back is enabled (see \-playback option) the program exits when
-end of file is reached. Otherwise the machine will continue to run.
-Default is OFF (\-noexit_after_playback).
-.TP
-.B \-record, \-rec \fIfilename
-Specifies a file to record all input from a system session. This can be
-used to record a system session for later playback. This feature does not
-work reliably for all systems, but can be used to watch a previously
-recorded system 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).
-.TP
-.B \-[no]record_timecode
-Specify whether to create a timecode file. It contains a line with elapsed
-times on each press of timecode shortcut key (default is F12).
-This option works only when recording mode is enabled (\-record option).
-The file is saved on inp folder.
-Default is OFF (\-norecord_timecode).
-.TP
-.B \-mngwrite \fIfilename
-Writes each video frame to the given file in MNG format, producing
-an animation of the system 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).
-.TP
-.B \-aviwrite \fIfilename
-Stream video and sound data to the given file
-in AVI format, producing an animation of the system session complete
-with sound. The default is NULL (no recording).
-.TP
-.B \-wavwrite \fIfilename
-Writes the final mixer output to the given file
-in WAV format, producing an audio recording of the system session.
-The default is NULL (no recording).
-.TP
-.B \-snapname \fIstring
-Describes how MESS should name files for snapshots. \fIstring\fP
-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 literal \fB%g\fP
-represents the driver name of the current system; and the literal \fB%i\fP
-represents an incrementing index. If \fB%i\fP is omitted, then each
-snapshot taken will overwrite the previous one; otherwise, MESS will
-find the next empty value for \fB%i\fP and use that for a filename. The
-default is \fB%g/%i\fP, which creates a separate folder for each system,
-and names the snapshots under it starting with 0000 and increasing
-from there. In addition to the above, for drivers using different
-media, like carts or floppy disks, you can also use the
-\fB%d\fP\fI_[media]\fP indicator. Replace \fI[media]\fP with the media
-switch you want to use. A few examples: if you use
-.B mess nes \-cart robby \-snapname %g/%d_cart
-snapshots will be saved as \fBsnaps/nes/robby.png\fP; if you use
-.B mess c64 \-flop1 robby \-snapname %g/%d_flop1/%i
-snapshots will be saved as \fBsnaps/c64/robby/0000.png\fP.
-.TP
-.B \-snapsize \fIwidth\fRx\fIheight
-Hard\-codes the size for snapshots and movie recording. By default,
-MESS will create snapshots at the system's current resolution in raw
-pixels, and will create movies at the system's starting resolution in
-raw pixels. If you specify this option, then MESS 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
-system is vertically oriented. The default is 'auto'.
-.TP
-.B \-snapview internal\fR|\fBauto\fR|\fIviewname
-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 \fIviewname\fP does not need to be a perfect match; rather, it
-will select the first view whose name matches all the characters
-specified by \fIviewname\fP. For example, \-snapview native will match the
-"Native (15:14)" view even though it is not a perfect match.
-\fIviewname\fP can also be 'auto', which selects the first view with all
-screens present. The default value is 'internal'.
-.TP
-.B \-[no]snapbilinear
-Specify whether snapshot/movie should have bilinear filtering applied.
-Default is ON (\-snapbilinear).
-.TP
-.B \-statename \fIstring
-Describes how MESS should store save state files, relative to the
-state_directory path. \fIstring\fP provides a template that
-is used to generate a relative path. Two simple substitutions are
-provided: the / character represents the path separator on any target
-platform (even Windows); the literal \fB%g\fP represents the driver name of
-the current game. The default is '%g', which creates a separate folder
-for each game. In addition to the above, for drivers using different
-media, like carts or floppy disks, you can also use the
-\fB%d_\fP\fI[media]\fP indicator. Replace \fI[media]\fP with the media
-switch you want to use. A few examples: if you use
-.B mess nes \-cart robby \-statename %g/%d_cart
-save states will be stored inside \fBsta/nes/robby/\fP; if you use
-.B mess c64 \-flop1 robby \-statename %g/%d_flop1
-save states will be stored inside \fBsta/c64/robby/\fP.
-.TP
-.B \-[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 systems. 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 system/burnin\-<screen.name>.png. The default is OFF (\-noburnin).

-running at full speed. Turning this on overrides the value you have set
-for \-frameskip below. The default is OFF (\-noautoframeskip).
-.TP
-.B \-frameskip, \-fs \fIvalue
-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 MESS will display 10 out of every 12 frames. By
-skipping those frames, you may be able to get full speed in a system that
-requires more horsepower than your computer has. The default value is 0,
-which skips no frames.
-.TP
-.B \-seconds_to_run, \-str \fIvalue
-This option can be used for benchmarking and automated testing. It tells
-MESS 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 MESS performance. In addition,
-upon exit, the \-str option will write a screenshot called final.png
-to the system's snapshot directory.
-.TP
-.B \-[no]throttle
-Configures the default thottling setting. When throttling is on, MESS
-attempts to keep the system running at the system's intended speed. When
-throttling is off, MESS runs the system as fast as it can. Note that the
-fastest speed is more often than not limited by your graphics card,
-especially for older systems. The default is ON (\-throttle).
-.TP
-.B \-[no]sleep
-Allows MESS to give time back to the system when running with \-throttle.
-This allows other programs to have some CPU time, assuming that the
-system 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).
