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, *.msa and *.stx 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. It boots faster than original TOS versions, but some buggy (floppy only) programs won't work
correctly with it. For best compatibility, 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. These
shortcuts correspond to "-d <dir>", "--disk-a <floppy image>" and "-d <dir> --auto C:<program>" options.
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:). If you want to give floppy image name with an
autostarting program name, give it with --disk-a option before the program name.
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>
Read additional configuration values from <file>, these override values read from the global and
user configuration files
-k, --keymap <file>
Load keyboard mapping from <file>
--fast-forward <bool>
On fast machine helps skipping (fast forwarding) Hatari output
--auto <program>
Autostarts given program, if TOS finds it. Program needs to be given with full path it will have
under emulation, for example "C:\DIR\PROGRAM.PRG". This is implemented by providing TOS a virtual
INF file, including that path as what TOS should start automatically
Common display options
-m, --mono
Start in monochrome mode instead of color
--monitor <x>
Select monitor type (x = mono/rgb/vga/tv)
--tos-res <x>
Select TOS resolution for color monitors (x = low/med/high/ttlow/ttmed)
-f, --fullscreen
Start the emulator in fullscreen mode
-w, --window
Start the emulator in windowed mode
--grab Grab mouse (also) in windowed mode
--resizable <bool>
Allow window resizing
NOTE: this is supported only by Hatari SDL2 build
--borders <bool>
Show ST/STE/Falcon screen borders (for low/med resolution overscan demos)
--frameskips <x>
Skip <x> frames after each displayed frame to accelerate emulation (0=disabled, >4 uses automatic
frameskip with given value as maximum)
--slowdown <x>
Slow down emulation by factor of x (used as multiplier for VBL wait time)
--mousewarp <bool>
To keep host mouse better in sync with Atari mouse pointer, center it to Hatari window on cold
reset and resolution changes
--statusbar <bool>
Show statusbar (with floppy leds etc etc)
--drive-led <bool>
Show overlay drive led when statusbar isn't shown
--max-width <x>
Preferred / maximum window width for borders / zooming
--max-height <x>
Preferred / maximum window height for borders / zooming
--bpp <bool>
Force internal bitdepth (x = 8/15/16/32, 0=disable)
--disable-video <bool>
Run emulation without displaying video (audio only)
ST/STE specific display options
--desktop-st <bool>
NOTE: this has effect only for SDL1 Hatari build. In SDL2 build, --desktop option controls also
ST/STe mode.
Whether to use desktop resolution on fullscreen to avoid issues related to resolution switching
(messing multi-screen setups, several seconds delay needed for resolution switching by some LCD
monitors and the resulting sound break). Otherwise fullscreen will use a resolution that is
closest to the Hatari window size.
As Hatari ST/STe display code doesn't support zooming (except low-rez doubling), it doesn't get
scaled (by Hatari or monitor) when this is enabled, and you may get large black borders around
ST/STe screen. Therefore this is mainly useful only if you suffer from the described effects, but
still want to grab mouse and remove other distractions from the screen just by toggling fullscreen
mode. (disabled by default)
--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)
--video-timing <x>
Wakeup State for MMU/GLUE (x=ws1/ws2/ws3/ws4/random, default ws3). When powering on, the STF will
randomly choose one of these wake up states. The state will then affect the timings where border
removals and other video tricks should be made, which can give different results on screen. For
example, WS3 is known to be compatible with many demos, while WS1 can show more problems.
TT/Falcon 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. (enabled by
default)
--force-max <bool>
Hatari window size is forced to specified maximum size and black borders used when Atari
resolution doesn't scale evenly to it. This is most useful when recording videos of Falcon demos
that change their resolution. (disabled by default)
--aspect <bool>
Whether to do monitor aspect ratio correction (enabled by default)
VDI options
--vdi <bool>
Whether to use VDI screen mode. Doesn't work with TOS v4. TOS v3 memory detection isn't
compatible with larger VDI modes (i.e. you need to skip the detection at boot)
--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 <= 2048)
--vdi-height <h>
Use extended VDI resolution with height <h> (200 < h <= 1280)
TOS and some popular GEM programs add extra restrictions for the VDI screen size. In total screen can
take at maximum 300kB, width needs to be multiple of 128/planes, and height multiple of 16 pixels (or 8,
depending on system font height). That translates to following maximum standard resolutions for the VDI
mode:
monochrome
FullHD (1920×1080), WUXGA (1920x1200) and QWXGA (2048x1152)
2 plane mode (4 colors)
HD (1280x720), WXGA (1280x768) and XGA+ (1152x864)
4 plane mode (16-colors)
qHD (960x540), DVGA (960x640) and WSVGA (1024x600)
Screen capture options
--crop <bool>
Remove statusbar from the screen captures
--avirecord
Start AVI recording. Note: recording will automatically stop when emulation resolution changes.
--avi-vcodec <x>
Select AVI video codec (x = bmp/png). PNG compression can be much slower than using the
uncompressed BMP format, but uncompressed video content takes huge amount of space.
--png-level <x>
Select PNG compression level for AVI video (x = 0-9). Both compression efficiency and speed
depend on the compressed screen content. Highest compression level (9) can be really slow with
some content. Levels 3-6 should compress nearly as well with clearly smaller CPU overhead.
--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 <bool>
Whether to enable MIDI support (PortMidi only)
--midi-in <filename>
Enable MIDI support and write raw MIDI data to <file> (Linux only)
--midi-out <filename>
Enable MIDI support and read raw MIDI data from <file> (Linux only)
--rs232-in <filename>
Enable MFP serial port support and use <file> as the input device
--rs232-out <filename>
Enable MFP serial port support and use <file> as the output device
--scc-b-out <filename>
Enable SCC channel B serial port support and use <file> for the output (only for Mega-STE, TT and
Falcon)
Floppy drive options
--drive-a <bool>
Enable/disable drive A (default is on)
--drive-b <bool>
Enable/disable drive B (default is on)
--drive-a-heads <x>
Set number of heads for drive A (1=single sided, 2=double sided)
--drive-b-heads <x>
Set number of heads for drive B (1=single sided, 2=double sided)
--disk-a <file>
Set disk image for floppy drive A
--disk-b <file>
Set disk image for floppy drive B
--fastfdc <bool>
speed up FDC emulation (can cause incompatibilities)
--protect-floppy <x>
Write protect floppy image contents (on/off/auto). With "auto" option write protection is
according to the disk image file attributes
Hard drive options
-d, --harddrive <dir>
GEMDOS HD emulation. Emulate harddrive partition(s) with <dir> contents. If directory contains
only single letter (C-Z) subdirectories, each of these subdirectories will be treated as a
separate partition, otherwise the given directory itself will be assigned to drive "C:". In the
multiple partition case, the letters used as the subdirectory names will determine to which
drives/partitions they are assigned. If <dir> is an empty string, then harddrive's emulation is
disabled
--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
--gemdos-case <x>
Specify whether new dir/filenames are forced to be in upper or lower case with the GEMDOS HD
emulation. Off/upper/lower, off by default
--gemdos-time <x>
Specify what file modification timestamps should be used, emulation internal (atari) ones, or ones
from the machine (host) on which the machine is running. While Atari emulation and host clocks are
in sync at Hatari startup, they will diverge while emulation is running, especially if you use
fast forward. Default is "atari". If you modify files accessed by the Atari side, directly from
the host side while Hatari is already running, you may want to use "host" option
--gemdos-conv <bool>
Whether GEMDOS file names with 8-bit (non-ASCII) characters are converted between Atari and host
character sets. On Linux, host file name character set is assumed to be UTF-8. This option is
disabled by default, in case you have transferred files from Atari machine without proper file
name conversion (e.g. by zipping them on Atari and unzipping on PC)
--gemdos-drive <drive>
Assign (separately specified) GEMDOS HD to given drive letter (C-Z) instead of default C:, or use
"skip" to specify that Hatari should add GEMDOS HD after IDE and ACSI drives (assumes Hatari and
native HD driver parse same number of partitions from the partition tables in HD images)
--acsi <id>=<file>
Emulate an ACSI hard disk with given BUS ID (0-7) using image <file>. If just a filename is
given, it is assigned to BUS ID 0
--scsi <id>=<file>
Emulate a SCSI hard disk with given BUS ID (0-7) using image <file>. If just a filename is given,
it is assigned to BUS ID 0
--ide-master <file>
Emulate an IDE 0 (master) hard disk with an image <file>
--ide-slave <file>
Emulate an IDE 1 (slave) hard disk with an image <file>
--ide-swap <id>=<x>
Set byte-swap option <x> (off/on/auto) for given IDE <id> (0/1). If just option is given, it is
applied to IDE 0
Memory options
--memstate <file>
Load memory snap-shot <file>
-s, --memsize <x>
Set amount of emulated ST RAM, x = 1 to 14 MiB, or 0 for 512 KiB. Other values are considered as
a size in KiB
-s, --ttram <x>
Set amount of emulated TT RAM, x = 0 to 512 MiB (in 4MB steps)
ROM options
-t, --tos <imagefile>
Specify TOS ROM image to use
--patch-tos <bool>
Use this option to enable/disable TOS ROM patching. Experts only! Leave this enabled unless you
know what you are doing!
--cartridge <imagefile>
Use ROM cartridge image <file> (only works if GEMDOS HD emulation and extended VDI resolution are
disabled)
Common 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
WinUAE CPU core options
--cpu-exact <bool>
Use cycle exact CPU emulation (cache emulation)
--addr24 <bool>
Use 24-bit instead of 32-bit addressing mode (24-bit is enabled by default)
--fpu <x>
FPU type (x=none/68881/68882/internal)
--fpu-softfloat <bool>
Use full software FPU emulation (Softfloat library)
--mmu <bool>
Use MMU emulation
Misc system options
--machine <x>
Select machine type (x = st, megast, ste, megaste, tt or falcon)
--blitter <bool>
Enable blitter emulation (ST only)
--dsp <x>
Falcon DSP emulation (x = none, dummy or emu, Falcon only)
--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.
--fast-boot <bool>
Patch TOS and initialize the so-called "memvalid" system variables to by-pass the memory test of
TOS, so that the system boots faster.
Sound options
--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.
--sound-sync <bool>
The emulation rate is nudged by +100 or 0 or -100 micro-seconds on occasion. This prevents the
sound buffer from overflowing (long latency and lost samples) or underflowing (short latency and
repeated samples). The emulation rate smoothly deviates by a maximum of 0.58% until synchronized,
while the emulator continuously generates every sound sample and the crystal controlled sound
system consumes every sample.
(on|off, off=default)
--ym-mixing <x>
Select a method for mixing the three YM2149 voice volumes together. "model" uses a mathematical
model of the YM voices, "table" uses a lookup table of audio output voltage values measured on STF
and "linear" just averages the 3 YM voices.
Debug options
-W, --wincon
Open console window (Windows only)
-D, --debug
Toggle whether CPU exceptions invoke the debugger
--debug-except <flags>
Specify which exceptions invoke debugger, see --debug-except help for available (comma separated)
exception flags.
--bios-intercept <bool>
Enable/Disable XBios command parsing. Allows Atari programs to use all Hatari functionality and
change Hatari state through Hatari specific XBios(255) calls. XBios(20) printscreen calls produce
also Hatari screenshots. XBios(11) Dbmsg call can be used to invoke the debugger.
--conout <device>
Enable console (xconout vector functions) output redirection for given <device> to host terminal.
Device 2 is for the (CON:) VT52 console, which vector function catches also EmuTOS panic messages
and MiNT console output, not just normal BIOS console output.
--disasm <x>
Set disassembly options. 'uae' and 'ext' select the dissasembly engine to use, bitmask sets
output options for the external disassembly engine and 'help' lists them.
--natfeats <bool>
Enable/disable (basic) Native Features support. E.g. EmuTOS uses it for debug output.
--trace <flags>
Activate debug traces, see --trace help for available (comma separated) tracing flags
--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 <path>
Hatari connects to given local socket file and reads commands from it. Use when the control
process life-time is longer than Hatari's, or control process needs response from Hatari
--cmd-fifo <path>
Hatari creates the indicated FIFO file and reads commands from it. Commands can be echoed to FIFO
file, and are same as with the control socket. Hatari outputs help for unrecognized commands and
subcommands
--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
--benchmark
Start in benchmark mode (use with --run-vbls). Allows measuring the speed of the emulation in
frames per second by running at maximum speed (don't wait for VBL). Disable audio/video output to
have as little OS overhead as possible
INPUT HANDLING
Hatari provides special input handling for different purposes.
Emulated Atari ST joystick
Joystick can be emulated either with keyboard or any real joystick supported by your kernel / SDL
library. First joystick button acts as FIRE, second as SPACE key.
Emulated Atari ST mouse
Middle button mouse click is interpreted as double click, this is especially useful in Fast Forward mode.
Mouse scrollwheel will act as cursor up and down keys.
Emulated Atari ST keyboard
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. How the PC keys are mapped to Atari key codes, can be changed
with keyboard config file (-k option).
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
Print will emulate the ST's HELP key
Scroll lock
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.
Keyboard shortcuts during emulation
The shortcut keys can be configured in the configuration file. The default settings are:
AltGr + a
record animation
AltGr + g
grab a screenshot
AltGr + i
boss key: leave full screen mode and iconify window
AltGr + m
(un-)lock the mouse into the window
AltGr + r
warm reset the ST (same as the reset button)
AltGr + c
cold reset the ST (same as the power switch)
AltGr + d
open dialog to select/change disk A
AltGr + s
enable/disable sound
AltGr + q
quit the emulator
AltGr + x
toggle normal/max speed
AltGr + y
enable/disable sound recording
AltGr + k
save memory snapshot
AltGr + l
load memory snapshot
AltGr + j
toggle joystick emulation via cursor keys
AltGr + F1
switch joystick type on joy port 0
AltGr + F2
switch joystick type on joy port 1
AltGr + F3
switch joystick type for joypad A
AltGr + F4
switch joystick type for joypad B
AltGr + b
toggle borders on/off
AltGr + f or F11
toggle between fullscreen and windowed mode
AltGr + o or 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
Keyboard shortcuts for the SDL GUI
There are multiple ways to interact with the SDL GUI.
TAB and cursor keys change focus between UI elements. Additionally Home key moves focus to first item,
End key to last one. Initially focus is on default UI element, but focus changes are remembered between
dialog invocations. Enter and Space invoke focused item. UI elements with underlined characters can be
invoked directly with Alt + key with that character. Alt + arrow keys will act on arrow buttons.
Most importantly:
Options GUI main view
Enter accepts configuration, ESC cancels it.
Options GUI dialogs
Enter (or End+Enter if focus was moved) returns back to main view.
Fileselector
Page up and down keys scroll the file list. Enter on focused file name selects it. Enter on OK
button accepts the selected file. ESC cancels the dialog/selection.
Alert dialogs
Enter accepts and ESC cancels the dialog.
