-.\" *******************************************************
-.TP
-.B \-state \fIslot
-Immediately after starting the specified system, will cause the save
-state in the specified slot to be loaded.
-.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 \fIfile
-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 \-record, \-rec \fIfile
-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 \-snapname \fIname
-Describes how MESS should name files for snapshots.
-.I name
-is a string that provides a template that is used to generate a file name.
-Three simple substitutions are provided:
-.RS
-.TP
-.B /
-represents the path separator on any target platform (even Windows)
-.TP
-.B %g
-represents the driver name of the current system
-.TP
-.B %i
-represents an incrementing index. If omitted, then each snapshot taken
-will overwrite the previous one; otherwise, MESS will find the next
-empty value for %i and use that for a file name.
-.P
-The default is '%g/%i', which creates a separate folder for each system,
-and names the snapshots under it starting with 0000 and increasing
-from there.
-.RE
-.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|\fIview
-Specifies the view to use when rendering snapshots and movies.
-.RS
-.TP 12
-.B internal
-renders a separate snapshot per screen or renders movies only of the
-first screen using the special 'internal' view.
-.TP
-.B auto
-selects the first view with all screens present
-.TP
-.I view
-select the first view whose name matches all the characters.
-For example,
-.B mame \-snapview native
-will match the "Native (15:14)" view even though it is not a perfect
-match.
-.P
-The default value is 'internal'.
-.RE
-.TP
-.B \-mngwrite \fIfile
-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 \fIfile
-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 \fIfile
-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 \-[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).

-.TP
-.B \-[no]autoframeskip, \-[no]afs
-Automatically determines the frameskip level while you're playing the
-system, adjusting it constantly in a frantic attempt to keep the system
-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).
-.TP
-.B \-speed
-Controls the speed of gameplay, relative to realtime; smaller numbers are
-slower. Default is 1.00.
-.TP
-.B \-refreshspeed, \-rs
-Automatically adjusts the \-speed parameter to keep the effective refresh
-rate below that of the lowest screen refresh rate.

-.B \-[no]rotate
-Rotate the system to match its normal state (horizontal/vertical). This
-ensures that both vertically and horizontally oriented systems show up
-correctly without the need to rotate your monitor. If you want to keep
-the system displaying 'raw' on the screen the way the actual machine would
-have, turn this option off. The default is ON (\-rotate).
-.TP
-.B \-[no]ror
-.TP
-.B \-[no]rol
-Rotate the system screen to the right (clockwise) or left
-(counter\-clockwise) relative to either its normal state (if \-rotate

-default for both of these options is OFF (\-noror \-norol).
-.TP
-.B \-[no]autoror
-.TP
-.B \-[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 system 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.
-.TP
-.B \-[no]flipx
-.TP
-.B \-[no]flipy
-Flip (mirror) the system screen either horizontally (\-flipx) or

-mechanisms. If this feature is enabled, then attempts to enter a coin

-Enables support for special controllers. Configuration files are
-loaded from the ctrlrpath. They are in the same format as the .cfg

-.TP
-.B \-[no]mouse
-Controls whether or not MESS 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 running
-MESS. If you want to get control of your computer back, you will need
-to either pause MESS or quit. The default is OFF (\-nomouse).

-.B \-[no]joystick, \-[no]joy
-Controls whether or not MESS looks for joystick/gamepad controllers.
-The default is ON (\-joystick).
-.TP
-.B \-[no]lightgun, \-[no]gun
-Controls whether or not MESS 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).
-.TP
-.B \-[no]multikeyboard, \-[no]multikey
-Determines whether MESS 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 MESS to report keypresses
-on different keyboards independently. The default is OFF
-(\-nomultikeyboard).
-.TP
-.B \-[no]multimouse
-Determines whether MESS 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 MESS to report mouse
-movement and button presses on different mice independently. The
-default is OFF (\-nomultimouse).
-.TP
-.B \-[no]steadykey, \-[no]steady
-Some systems 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).
-.TP
-.B \-[no]offscreen_reload, \-[no]reload
-Controls whether or not MESS treats a second button input from a
-lightgun as a reload signal. In this case, MESS 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 systems 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).

-.B \-joystick_deadzone, \-joy_deadzone, \-jdz \fIvalue
-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.
-.TP
-.B \-joystick_saturation, \-joy_saturation, \-jsat \fIvalue
-If you play with an analog joystick, the ends can drift a little,
