-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.

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|heightR|both

When -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
