ATARI800(1)

NAME
atari800 - Atari 800 Emulator, Version 0.3.0

SYNOPSIS
atari800 [options] [diskfiles...]

DESCRIPTION
atari800 emulates the Atari 800, Atari 800 XL and Atari 130 XE.

  Options

-a  Use Atari OS/A.

-b  Use Atari OS/B.

-xl Emulate Atari 800 XL.

-xe Emulate Atari 130 XE - but Antic accesses the same bank the CPU is using.

-ffp
    Replace standard floating point with a set of fast floating point routines implemented within the emulator without using 6502 CPU emulation.

-emuos
    Enables emulation of Operating System. The Original Atari ROMs are not required when this option is selected, however the emulation is nowhere near 100% complete. This option also implies the -ffp option.

-rom
    The following file is a standard 8K ROM cartridge.

-rom16
    The following file is a standard 16K ROM cartridge.

-oss
    The following file is an OSS super-cartridge.

-db The following file is a DB super-cartridge.

-c  Enable RAM between $c000 and $d000.

-h  The following argument is used as the directory for the H: device.

-v  Print emulator version.

-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.

-countdown
    Controls the number of instructions that are executed in the vertical blank period. The default value is 4000.

  SVGALIB Options

-sound
    Enable sound using the Network Audio System.

-interlace
    Enable screen interlace option

  X Window Options

-small
    Runs 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 rectange. 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 rectange.

-sound
    Enable sound using the Network Audio System.

  Amiga Options

-ocs
    Used for OCS based Amigas. It has not been tested on a real OCS based computer and there could be problems with regard to Workbench versions.

-ecs
    Used for ECS based Amigas. It has not been tested on a real ECS based computer and there could be problems with regard to Workbench versions.

-aga
    Used for AGA based Amigas. It has been tested on an Amiga 1200 with 68030 + 4Mb Fast RAM.

-grey
    Produce a grey scale display.

-colour
    Produce a full colour on AGA machines and up to 32 simultaneous colours on OCS and ECS machines.

-wb Runs the emulator in a Workbench Window. Use a screen mode with a minimum of 16 colours for best results.

  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.

FILES

BUGS
A few programs cause the emulator to enter its built in debugger. The reason for this is unknown at the moment. Antic Modes 2, 3 and f display two true colours and not one colour with two luminances. Should this be called a bug or feature, and should it be corrected?
