HATARI(1)

NAME
hatari - Atari ST/STE/TT/Falcon emulator

SYNOPSIS
hatari [options] [directory|diskimage|program]

DESCRIPTION
Hatari is an Atari ST/STE/TT/Falcon emulator for Linux, FreeBSD, BeOS and other Systems which are supported by the SDL library.

With hatari one can run games, demos or applications written for Atari ST, STE or Falcon. Atari TT support is experimental. Hatari supports the commonly used *.st and *.msa disk images and hard disk emulation.

To run the emulator a TOS ROM image is needed. EmuTOS, a free implementation of TOS is shipped with hatari. Since it is not yet fully compatible with the original TOS, some programs won't run correctly with it. Because of this it is recommended to use a TOS ROM from a real Atari.

As an argument one can give either a name of a directory that should be emulated as a virtual GEMDOS hard disk, a floppy disk image or an Atari program that should be autostarted. In the last case the program's directory will be used as the C: drive from where this program will be started.

Note that autostarting a program might not work if you've also specified a floppy image for drive A: (on command line or in config file) which contains a desktop.inf/newdesk.inf/emutos.inf file on it.

Booting will be done from the disk image or directory that's given last on the command line as an option or the argument (and which corresponds to A: or C:).

OPTIONS
Hatari options are split into several categories:

General options

-h, --help
    Print command line options and terminate

-v, --version
    Print version information and terminate

--confirm-quit <bool>
    Whether Hatari confirms quitting

-c, --configfile <filename>
    use the given file as configuration file instead of ~/.hatari/hatari.cfg

-k, --keymap <file>
    load keyboard mapping from <file>

--fast-forward <bool>
    On fast machine helps skipping (fast forwarding) Hatari output

Common display options

-m, --mono
    Start in monochrome mode instead of color

--monitor <x>
    Select monitor type (x = mono/rgb/vga/tv)

-f, --fullscreen
    Start the emulator in fullscreen mode

-w, --window
    Start the emulator in window mode

--grab
    Grab mouse (also) in window mode

--frameskips <x>
    Skip <x> frames after each displayed frame to accelerate emulation (0=disabled, >4 uses automatic frameskip with given value as maximum)

--statusbar <bool>
    Show statusbar (with floppy leds etc etc)

--drive-led <bool>
    Show overlay drive led when statusbar isn't shown

--bpp <bool>
    Force internal bitdepth (x = 8/15/16/32, 0=disable)

ST/STE specific display options

--borders <bool>
    Show ST/STE screen borders (for low/med resolution overscan demos)

--spec512 <x>
    Hatari uses this threshold to decide when to render a screen with the slower but more accurate Spectrum512 screen conversion functions (0 <= x <= 512, 0=disable)

-z, --zoom <x>
    Zoom (double) low resolution (1=no, 2=yes)

Falcon/TT specific display options
Zooming to sizes specified below is internally done using integer scaling factors. This means that different Atari resolutions may show up with different sizes, but they are never blurry.

--desktop <bool>
    Whether to use desktop resolution on fullscreen to avoid issues related to resolution switching. Otherwise fullscreen will use a resolution that is closest to the Hatari window size

--max-width <x>
    Preferred / maximum window width

--max-height <x>
    Preferred / maximum window height

--aspect <bool>
    Whether to do monitor aspect ratio correction (enabled by default)

VDI options

--vdi <bool>
    Whether to use VDI screen mode

--vdi-planes <x>
    Use extended VDI resolution with bit depth <x> (x = 1, 2 or 4)

--vdi-width <w>
    Use extended VDI resolution with width <w> (320 < w <= 1280)

--vdi-height <h>
    Use extended VDI resolution with height <h> (200 < h <= 960)

Screen capture options

--crop <bool>
    Remove statusbar from the screen captures

--avirecord
    Start AVI recording

--avi-vcodec <x>
    Select avi video codec (x = bmp/png)

--avi-fps <x>
    Force avi frame rate (x = 50/60/71/...)

--avi-file <file>
    Use <file> to record avi

Devices options

-j, --joystick <port>
    Emulate joystick with cursor keys in given port (0-5)

--joy<port> <type>
    Set joystick type (none/keys/real) for given port

--printer <file>
    Enable printer support and write data to <file>

--midi-in <filename>
    Enable MIDI support and write MIDI data to <file>

--rs232-in <filename>
    Enable serial port support and use <file> as the input device

--rs232-out <filename>
    Enable serial port support and use <file> as the output device

Disk options

--disk-a <file>
    Set disk image for floppy drive A

--disk-b <file>
    Set disk image for floppy drive B

--protect-floppy <x>
    Write protect floppy image contents (on/off/auto). With "auto" option write protection is according to the disk image file attributes.

--protect-hd <x>
    Write protect harddrive <dir> contents (on/off/auto). With "auto" option the protection can be controlled by setting individual files attributes as it disables the file attribute modifications for the GEMDOS hard disk emulation.

    Emulate harddrive partition(s) with <dir> contents

--acsi <file>
    Emulate an ACSI hard disk with an image <file>

--ide-master <file>
    Emulate an IDE master hard disk with an image <file>

--ide-slave <file>
    Emulate an IDE slave hard disk with an image <file>

--slowfdc <bool>
    slow down FDC emulation (deprecated)

Memory options

-s, --memsize <x>
    Set amount of emulated RAM, x = 1 to 14 MiB, or 0 for 512 KiB

-t, --tos <imagefile>
    Specify TOS ROM image to use

--cartridge <imagefile>
    Use ROM cartridge image <file> (only works if GEMDOS HD emulation and extended VDI resolution are disabled)

--memstate <file>
    Load memory snap-shot <file>

CPU options

--cpulevel <x>
    Specify CPU (680x0) to use (use x >= 1 with EmuTOS or TOS >= 2.06 only!)

--cpuclock <x>
    Set the CPU clock (8, 16 or 32 Mhz)

--compatible <bool>
    Use a more compatible, but slower 68000 CPU mode with better prefetch accuracy and cycle counting

Misc system options

--machine <x>
    Select machine type (x = st, ste, tt or falcon)

--blitter <bool>
    Enable blitter emulation (ST only)

--dsp <x>
    Falcon DSP emulation (x = none, dummy or emu, Falcon only)

--mic <bool>
    Enable/disable (Falcon only) microphone

--sound <x>
    Sound frequency: 6000-50066. "off" disables the sound and speeds up the emulation. To prevent extra sound artifacts, the frequency should be selected so that it either matches evenly with the STE/TT/Falcon sound DMA (6258, 12517, 250033, 50066 Hz) or your sound card frequencies (11025, 22050, 44100 or 6000...48000 Hz). Check what your sound card supports.

--sound-buffer-size <x>
    SDL's sound buffer size: 10-100, or 0 to use default buffer size. By default Hatari uses an SDL buffer size of 1024 samples, which gives approximatively 20-30 ms of sound depending on the chosen sound frequency. Under some OS or with not fully supported sound card, this default setting can cause a bigger delay at lower frequency (nearly 0.5 sec). In that case, you can use this option to force the size of the sound buffer to a fixed number of milliseconds of sound (using 20 is often a good choice if you have such problems). Most users will not need this option.

--ym-mixing <x>
    Select a method for mixing the three YM2149 voice volumes together. "table" uses a lookup table of audio output voltage values measured on STF and "linear" just averages the 3 YM voices.

--timer-d <bool>
    Patch redundantly high Timer-D frequency set by TOS. This about doubles Hatari speed (for ST/e emulation) as the original Timer-D frequency causes most of the interrupts.

--rtc <bool>
    Enable real-time clock

Debug options

-D, --debug
    Toggle whether CPU exceptions invoke the debugger

--bios-intercept
    Toggle Bios/XBios call interception and BIOS CON: output (e.g. EmuTOS console) redirection to host terminal. Needed for Bios/XBios call tracing. Allows Atari programs to modify Hatari state through XBios 255 calls.

--trace <trace1,...>
    Activate debug traces, see --trace help for available tracing options

--trace-file <file>
    Save trace output to <file> (default=stderr)

--parse <file>
    Parse/execute debugger commands from <file>

--saveconfig
    Save Hatari configuration and exit. Hatari UI needs Hatari configuration file to start, this can be used to create it automatically.

--no-parachute
    Disable SDL parachute to get Hatari core dumps. SDL parachute is enabled by default to restore video mode in case Hatari terminates abnormally while using non-standard screen resolution.

--control-socket <file>
    Hatari reads options from given socket at run-time

--log-file <file>
    Save log output to <file> (default=stderr)

--log-level <x>
    Log output level (x=debug/todo/info/warn/error/fatal)

--alert-level <x>
    Show dialog for log messages above given level

--run-vbls <x>
    Exit after X VBLs

COMMANDS
The shortcut keys can be configured in the configuration file. The default settings are:

AltGr + a
    record animation

    enable/disable sound recording

AltGr + k
    save memory snapshot

AltGr + l
    load memory snapshot

F11 toggle between fullscreen and windowed mode

F12 activate the hatari options GUI
    You may need to hold SHIFT down while in windowed mode.

Pause
    Pauses the emulation

AltGr + Pause
    Invokes the internal Hatari debugger

Emulated Atari ST keyboard
All other keys on the keyboard act as the normal Atari ST keys so pressing SPACE on your PC will result in an emulated press of the SPACE key on the ST. The following keys have special meanings:

Alt will act as the ST's ALTERNATE key

left Ctrl
    will act as the ST's CONTROL key

Page Up
    will emulate the ST's HELP key

Page Down
    will emulate the ST's UNDO key

AltGr will act as Alternate as well as long as you do not press it together with a Hatari hotkey combination. The right Ctrl key is used as the fire button of the emulated joystick when you turn on joystick emulation via keyboard. The cursor keys will act as the cursor keys on the Atari ST as long as joystick emulation via keyboard has been turned off.
