If this option is not given, the user will be asked to choose the cartridge type when the emulator starts.
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).
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.
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.
Disable automatic reboot after cartridge inserting/removing.

Run Atari program (EXE, COM, XEX, BAS, LST)
Load saved-state file
Attach cassette image (CAS format or raw file)
Attach cassette image and boot it
Set the attached cassette image as read-only.

-1400
Emulate the Atari 1400XL
Emulate the Atari 1450XLD
Emulate the CSS Black Box
Emulate the ICD MIO board

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

Set path for H1: device
Set path for H2: device
Set path for H3: device
Set path for H4: device
Set path for Atari executables on the H: device
Enable read-only mode for H: device
Disable read-only mode for H: device
Put debugging messages for H: and P: devices in log file

Enable R-Time 8 emulation
Disable R-Time 8 emulation

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.

Do not use mouse
Emulate paddles
Emulate Atari Touch Tablet
Emulate Koala Pad
Emulate Light Pen

Record all input events to filename. Can be used for gaming contests (highest score etc).
Playback input events from filename. Watch an expert play the game.

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:
Disable video artifacts.
Simple emulation of NTSC composite video artifacts. Fast but inaccurate.
Improved emulation of NTSC artifacts. May look better than ntsc-old.
Full emulation of NTSC artifacts. Rather slow and available only in 16- and 32-bit video modes.
Simple emulation of PAL chroma blending, without composite artifacts. Fast but inaccurate.
Accurate emulation of PAL chroma blending, without composite artifacts. Available only in 16- and 32-bit video modes.
Set artifacting mode 0-4 (0 = disable). Only for tv effects ntsc-old and ntsc-new.

Use one of predefined colour adjustments
Set screen color saturation (like TV Colour control)
-ntsc-saturation n, -pal-saturation n
Set saturation only for NTSC or PAL, respectively
Set screen contrast (also called white level)
-ntsc-contrast n, -pal-contrast -fIn
Set contrast only for NTSC or PAL, respectively
Set screen brightness (also called black level)
-ntsc-brightness n, -pal-brightness n
Set brightness only for NTSC or PAL, respectively

Set GTIA color delay for NTSC system. This emulates adjusting the potentiometer existing at the bottom of Atari computers, which adjusts hues of colors produced by the computer.
-pal-colordelay n
Set GTIA color delay for PAL system.

Read Atari NTSC/PAL colors from ACT file
Apply colour adjustments (brightness, contrast etc.) to the loaded NTSC/PAL palette (by default the loaded palette is displayed unmodified).

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.

Show percentage of actual speed

Enable sound
Disable sound
Set sound output frequency in Hz. The default is 44100 Hz.
Set sound output format to 16-bit
Set sound output format to 8-bit
Set length of the hardware sound buffer in milliseconds. Setting to 0 (the default) causes the length to be set automatically. Higher values increase sound latency. Automatic setting should be OK in most cases.
Set sound latency in milliseconds. Increase it if you experience gaps of silence during sound playback.

Curses Options

Use columns 0 to 39
Use columns 20 to 59
Use columns 40 to 79
Use columns 0 to 79. In this mode only the even character positions are used. The odd locations are filled with spaces.
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

Generate Falcon screen only every x frame
Direct VIDEL programming (Falcon/VGA only)
Double the screen size on NOVA
Delta screen output (differences only)

SDL Options

Start in fullscreen mode. The default resolution is 336x240 and can be later changed.
Start in a window (the default).
Rotate display (useful for devices with 240x320 screen).
Don't rotate display (the default).
Host horizontal resolution for fullscreen.
Host vertical resolution for fullscreen.
Set horizontal size of the window. The window can be later resized manually.
Set vertical size of the window. The window can be later resized nanually.
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.
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.
Disable synchronization with monitor's vertical retrace (the default).
Set amount of visible screen horizontally:

Shows 320 pixels.
The default. Shows area visible on a standard TV (336 pixels).
Shows full overscan area (384 pixels).
An exact horizontal size can be set by providing a number between 160 and 384.
Set amount of visible screen vertically:

Shows 200 pixels.
The default. Shows area visible on a typical TV (224 or 240 pixels, depending on current TV system).
Shows full overscan area, which can be up to 300 pixels in case of the XEP80.
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.

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).
Choose method of stretching the image to fit the screen/window area:

The image won't be stretched at all.
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.
The screen will fit the entire screen/window area. This setting looks best in high screen resolutions.
A custom multiplier (floating point number) can be also provided to precisely set the amount of stretching.
When -stretch is set to integral or full, this parameter controls how the stretching is performed with relation to window/screen size:

Fits the image's width while allowing it to be cropped vertically.
Fits the image's height while allowing it to be cropped horizontally.
The default. Fit both the image's width and height, avoiding cropping.
Choose how the image's aspect ratio should be maintained when stretching:

Causes the image to be stretched without restriction to fit the screen/window area fully.
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.
Recreates the aspect ratio of a real TV display (pixels are not square), but only if the -host-aspect-ratio option is set correctly.
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.
Deactivates showing output of an 80 column hardware.

Do not initialize SDL joysticks
Define path to device used in LPTjoy 0. Available on linux-ia32 only.
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.
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).
Enable scanlines interpolation (looks nicer).
Disable scanlines interpolation (in software modes may give better performance).
Use OpenGL hardware acceleration for displaying and stretching of the emulator's display. Using OpenGL improves performance.
Don't use OpenGL hardware acceleration (the default).
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.
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.
Don't use Pixel Buffer Objects when OpenGL acceleration is used.
Enable bilinear filtering of the screen in OpenGL modes.
Disable bilinear filtering in OpenGL modes (the default).
Provide a custom OpenGL shared library. If not given, Atari800 will use a default system-specific library (typically opengl32.dll or libGL.so).
Emulate a prototype 80 column board for the 1090
Emulate the XEP80
Use XEP80 on joystick port n
Emulate the Austin Franklin 80 column daughterboard for Atari 800.
Sets global volume of Atari 800.
