       If  this option is not given, the user will be asked to choose the cartridge type when the
       emulator starts.

       -cart2 filename
              Insert piggyback cartridge (CART or raw format).  This  works  only  if  the  first
              cartridge is a pass-through (currently only SpartaDOS X 64KB and 128KB types).

       -cart2-type 0..67
              Select type of the cartridge inserted with the -cart2 option.  When inserting a raw
              ROM image its type cannot be detected automatically, and must be provided with this
              option.  The available values are the same as for the -cart-type option above.

       -cart-autoreboot
              Automatically  reboot  after  cartridge  inserting/removing  (this  is  the default
              setting).  This does not apply to the piggyback cartridge - inserting  or  removing
              it never causes automatic reboot.

       -no-cart-autoreboot
              Disable automatic reboot after cartridge inserting/removing.

       -run filename
              Run Atari program (EXE, COM, XEX, BAS, LST)

       -state filename
              Load saved-state file

       -tape filename

       -boottape filename
              Attach cassette image and boot it

       -tape-readonly
              Set the attached cassette image as read-only.

       -1400  Emulate the Atari 1400XL

       -xld   Emulate the Atari 1450XLD

       -bb    Emulate the CSS Black Box

       -mio   Emulate the ICD MIO board

       -nopatch
              Normally  the  OS is patched giving very fast I/O.  This options prevents the patch
              from being applied so that the OS accesses the serial port hardware directly.  This
              option will probably never be needed since programs that access the serial hardware
              should work even if the OS has been patched.

       -nopatchall
              Don't patch OS at all, H:, P: and R: devices won't work

       -H1 path
              Set path for H1: device

              Set path for H3: device

       -H4 path
              Set path for H4: device

       -Hpath path
              Set path for Atari executables on the H: device

       -hreadonly
              Enable read-only mode for H: device

       -hreadwrite
              Disable read-only mode for H: device

       -devbug
              Put debugging messages for H: and P: devices in log file

       -rtime Enable R-Time 8 emulation

       -nortime
              Disable R-Time 8 emulation

       -rdevice [dev]
              Enable R: device.  If dev is specified then it's used as host  serial  device  name
              (e.g.   /dev/ttyS0  on linux).  If there is no dev specified then R: is directed to
              network.

              Playback input events from filename. Watch an expert play the game.

       -refresh
              Controls  screen  refresh  rate.   A  numerical  value  follows  this  option which
              specifies how many emulated screen updates are required before the actual screen is
              updated.   This value effects the speed of the emulation: A higher value results in
              faster CPU emulation but a less frequently updated screen.

       -ntsc-artif mode, -pal-artif mode
              Set emulation mode of video artifacts in NTSC or PAL, respectively.  The  available
              values for mode are:
              none   Disable video artifacts.
              ntsc-old
                     Simple emulation of NTSC composite video artifacts. Fast but inaccurate.
              ntsc-new
                     Improved emulation of NTSC artifacts. May look better than ntsc-old.
              ntsc-full
                     Full  emulation of NTSC artifacts. Rather slow and available only in 16- and

       -paletten filename, -palettep filename
              Read Atari NTSC/PAL colors from ACT file

       -paletten-adjust, -palettep-adjust
              Apply colour adjustments (brightness, contrast etc.) to the loaded NTSC/PAL palette
              (by default the loaded palette is displayed unmodified).

       -screenshots pattern
              Set  filename  pattern  for screenshots.  Use to override the default atari000.png,
              atari001.png etc.  filenames.  Hashes are replaced with raising numbers.   Existing
              files are overwritten only if all the files defined by the pattern exist.

       -showspeed
              Show percentage of actual speed

       -sound Enable sound

       -nosound
              Disable sound

       -dsprate freq
              Set sound output frequency in Hz.  The default is 44100 Hz.

       -audio16
              Set sound output format to 16-bit

       -audio8
              Set sound output format to 8-bit

       -snd-fragsize size
              Set size of the hardware sound buffer (fragment size).  The value should be a power
              of 2.  Setting to 0 (the default) causes the size to be set automatically.   Higher
              values increase sound latency.  Automatic setting should be OK in most cases.

       -snddelay time
              Set  sound  latency in milliseconds.  Increase it if you experience gaps of silence
              during sound playback.

   Curses Options
       -left  Use columns 0 to 39

       -central
              Use columns 20 to 59

       -right Use columns 40 to 79

       -wide1 Use columns 0 to 79.  In this mode only the even character positions are used.  The
              odd locations are filled with spaces.

       -wide2 Use  columns 0 to 79.  This mode is similar to -wide1 except that the spaces are in
              reverse video if the previous character was also in reverse video.

   Falcon Options

   Java NestedVM Options
       -scale n
              Scale width and height by n

   SDL Options
       -fullscreen
              Start in fullscreen mode.  The default resolution  is  336x240  and  can  be  later
              changed.

       -windowed
              Start in a window (the default).

       -rotate90
              Rotate display (useful for devices with 240x320 screen).

       -no-rotate90
              Don't rotate display (the default).

       -fs-width number-of-pixels
              Host horizontal resolution for fullscreen.

       -fs-height number-of-pixels
              Host vertical resolution for fullscreen.

       -win-width number-of-pixels
              Set horizontal size of the window.  The window can be later resized manually.

       -win-height number-of-pixels
              Set vertical size of the window.  The window can be later resized nanually.

       -bpp number-of-bits
              Sets  image color depth when OpenGL acceleration is disabled.  Accepted values are:
              0 (use desktop depth; this is the default), 8, 16 and 32.  Depending on the type of
              graphics  hardware, the fullscreen setting and current desktop bit depth, either of
              the values might give the best performance.  Note that with bit  depth  set  to  16
              emulation of colors is slightly less accurate.

       -vsync Synchronize  the  display  with  the  monitor's  vertical  retrace, to remove image
              tearing artifacts.  This  improves  display  quality,  but  may  be  not  available
              depending   on   the   current   wideo   mode   (fullscreen/windowed),  the  chosen
              SDL_VIDEODRIVER and type of graphics hardware.  Synchronization  is  available  for
              some SDL videodrivers (directx, dga) but not for others.  In OpenGL this option has
              no effect - vertical synchronization must be instead enabled in the video  hardware
              driver's settings, if available.

       -no-vsync
              Disable synchronization with monitor's vertical retrace (the default).

       -horiz-area narrow|tv|full|number
              Set amount of visible screen horizontally:

              narrow Shows 320 pixels.
              tv     The default.  Shows area visible on a standard TV (336 pixels).
              full   Shows full overscan area (384 pixels).
              number An  exact  horizontal  size can be set by providing a number between 160 and
                     384.

       -vertical-area short|tv|full|number
              Set amount of visible screen vertically:

              short  Shows 200 pixels.
              tv     The default.  Shows area visible  on  a  typical  TV  (224  or  240  pixels,
                     depending on current TV system).
              full   Shows  full  overscan  area,  which  can  be up to 300 pixels in case of the
                     XEP80.
              number An exact number of visible scanlines  can  be  set  by  providing  a  number
                     between 100 and 300.

       Note  that  when  displaying  output of an XEP80 or Austin Franklin 80 column card, the tv
       setting will crop the top and bottom parts of text area, just like a real  TV  does  -  in
       such case setting the option to full would be more appriopriate.

       -horiz-shift number
              When  the  visible  horizontal  area  is not set to full, this option specifies the
              screen's area that will be visible.  Values higher than 0 will cause  showing  more
              of  the right side of the screen, while values lower than 0 will cause showing more
              of the left side.  The default is 0 (no shift).  -vert-shift number Analogically to
              -horiz-shift:  when  the  visible  vertical  area  is  not set to full, this option
              specifies the screen's area that will be visible.  Values higher than 0 will  cause
              showing more of the bottom part of the screen, while values lower than 0 will cause
              showing more of the top part.  The default is 0 (no shift).

       -stretch none|integral|full|number
              Choose method of stretching the image to fit the screen/window area:

              none   The image won't be stretched at all.
              integral
                     The default.  The image will fit the screen/window  but  will  be  stretched
                     only  by  an  integral multiplier.  This setting allows for nice output when
                     using scanlines in low screen resolutions.
              full   The screen will fit the entire screen/window area.  This setting looks  best
                     in high screen resolutions.
              number A  custom  multiplier  (floating  point  number)  can  be  also  provided to
                     precisely set the amount of stretching.

       -fit-screen width|heightWhen -stretch is set to integral or full, this parameter
              controls how the stretching is performed with relation to window/screen size:

              width  Fits the image's width while allowing it to be cropped vertically.
              height Fits the image's height while allowing it to be cropped horizontally.
              both   The default.  Fit both the image's width and height, avoiding cropping.

       -image-aspect none|square-pixels|real
              Choose how the image's aspect ratio should be maintained when stretching:

              none   Causes  the  image  to  be  stretched  without  restriction   to   fit   the
                     screen/window area fully.
              square-pixels
                     The  default.   Causes  the  image  to  be  stretched  by  the  same  amount
                     horizontally and vertically,  maintaining  square  pixels.   In  low  screen
                     resolutions this setting may produce the nicest result.
              real   Recreates the aspect ratio of a real TV display (pixels are not square), but
                     only if the -host-aspect-ratio option is set correctly.

       -host-aspect-ratio auto|x:y
              Set the aspect ratio of the host monitor on which the emulator's display is placed.
              Allowed  values  are  auto  for autodetection, or ratios like 4:3, 16:9, 1.25:1 ...
              This  value  is  used  to  properly  maintain  image's  aspect  ratio  when  having
              -image-aspect set to real.  The default value is auto.  Note that host aspect ratio
              detection works as expected only if the desktop resolution matches aspect ratio  of
              the  display  device (in other words, display pixels are square).  If, for example,
              desktop resolution is 800x600 on a 16:9 monitor, autodetection will fail  and  host
              aspect  ratio  will have to be set manually, by measuring physical width and height
              of the monitor and setting the parameter to width:height.

       -80column
              Shows output of an 80 column hardware, when it is available  (the  default).   This
              parameter  has  effect only if an 80 column hardware is activated, using one of the
              parameters -af80, -proto80 or -af80.

       -no-80column
              Deactivates showing output of an 80 column hardware.

       -nojoystick
              Do not initialize SDL joysticks

       -joy0 path-to-device
              Define path to device used in LPTjoy 0. Available on linux-ia32 only.

       -joy1 path-to-device
              Define path to device used in LPTjoy 1. Available on linux-ia32 only.

       -ntsc-filter-preset composite|svideo|rgb|monochrome
              Use one of predefined NTSC filter adjustments.

       -ntsc-sharpness n
              Set sharpness of the NTSC filter.

       -ntsc-resolution n
              Set resolution of the NTSC filter.

       -ntsc-artifacts n
              Set artifacts of the NTSC filter.

       -ntsc-fringing n
              Set fringing of the NTSC filter.

       -ntsc-bleed n
              Set bleed of the NTSC filter.

       -ntsc-burstphase n
              Set burst phase of the NTSC filter.  This changes colors of  artifacts.   The  best
              values are 0, 0.5, 1, 1.5.

       -scanlines n
              Set visibility of scanlines (0..100).  Scanlines are only visible when the screen's
              or window's vertical size is at least 480  (more  precisely,  at  least  twice  the
              number of scanlines given in -vert-area).

       -scanlinesint
              Enable scanlines interpolation (looks nicer).

       -no-scanlinesint
              Disable scanlines interpolation (in software modes may give better performance).

       -video-accel
              Use  OpenGL  hardware  acceleration for displaying and stretching of the emulator's
              display.  Using OpenGL improves performance.

       -no-video-accel
              Don't use OpenGL hardware acceleration (the default).

       -pixel-format bgr16|rgb16|bgra32|argb32
              Choose format of texture data when OpenGL acceleration is  enabled.   Depending  on
              the  type  of  the  graphics  hardware,  either  of  the values might give the best
              performance.  Note that with pixel format set  to  bgr16  or  rgb16,  emulation  of
              colors is slightly less accurate.

       -pbo   Use  Pixel  Buffer Objects when OpenGL acceleration is enabled (the default).  PBOs
              are available on newer graphics  hardware  and  when  used,  substantially  improve
              emulator's  performance.   However  in rare cases (some Intel on-board chips) using
              PBOs may actually descrease perfromance.

       -no-pbo
              Don't use Pixel Buffer Objects when OpenGL acceleration is used.

       -bilinear-filter
              Enable bilinear filtering of the screen in OpenGL modes.

       -no-bilinear-filter
              Disable bilinear filtering in OpenGL modes (the default).

       -opengl-lib path
              Provide a custom OpenGL shared library.  If not given, Atari800 will use a  default
              system-specific library (typically opengl32.dll or libGL.so).

       -proto80
              Emulate a prototype 80 column board for the 1090

       -xep80 Emulate the XEP80

       -xep80port n
              Use XEP80 on joystick port n

       -af80  Emulate the Austin Franklin 80 column daughterboard for Atari 800.

   X11 Options
       -small Run the emulator in a small window where each Atari 800 pixel is represented by one
              X Window pixel

       -large Runs the emulator in a large window where each Atari 800 pixel is represented by  a
              2x2 X Window rectangle. This mode is selected by default.

       -huge  Runs  the  emulator in a huge window where each Atari 800 pixel is represented by a
              3x3 X Window rectangle.

       -clip_x number-of-pixels
              Set left offset for clipping

       -clip_width number-of-pixels
              Set the width of the clipping-area

       The  following  keys  work  only  when  the  NTSC  filter  is  enabled (-ntsc-artif set to
       ntsc-full):
              LAlt+LShift+7  Decrease sharpness
              LAlt+7         Increase sharpness
              LAlt+LShift+8  Decrease resolution
              LAlt+8         Increase resolution
              LAlt+LShift+9  Decrease artifacts
              LAlt+9         Increase artifacts
              LAlt+LShift+0  Decrease fringing
              LAlt+0         Increase fringing
              LAlt+LShift+-  Decrease bleed
              LAlt+-         Increase bleed
              LAlt+LShift+=  Decrease NTSC burst phase (use this to change artifacting colours)
              LAlt+=         Increase NTSC burst phase

       LAlt+LShift+[  Decrease scanlines visibility
       LAlt+[         Increase scanlines visibility
       LAlt+]         Toggle NTSC composite/S-Video/RGB/monochrome settings

       LAlt+Shift+X   Enable/disable output of a 80 column hardware (use with -xep80, -proto80 or
                      -af80).

       Apart  from  standard  joysticks  (handled  by  the  SDL) up to two keyboard joysticks are
       supported. The keys used for joystick directions and the trigger can be freely defined  in
       the  config  UI  (Controller Config -> Define layout).  Keyboard joystick emulation can be
       enabled/disabled in the Controller Config.  By default, joy 0 is  enabled  and  joy  1  is
       disabled (to not steal normal AWDS keys in the emulator).

   X11
       Alt    Atari key (either Alt key will work)

       Joystick  0  is  operated  by the mouse position relative to the center of the screen. The
       mouse button acts as the trigger.  On Linux, standard joysticks are also supported.
