hatari — Atari ST/STE/TT/Falcon emulator
hatari [options] [directory|diskimage|program]
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.
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.
Hatari options are split into several categories:
- -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
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 windowed mode
- Grab mouse (also) in windowed mode
- --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)
ST/STE specific display options
- --desktop-st <bool>
- Whether fullscreen mode uses desktop resolution to avoid: messing multi-screen setups, several seconds delay needed by LCD monitors resolution switching and the resulting sound break. As Hatari ST/E display code doesn't support zooming (except low-rez doubling), it doesn't get scaled (by Hatari or monitor) when this is enabled. 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)
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 <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 <= 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
- 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
- -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>
- --midi-out <filename>
- Enable MIDI support and read MIDI data from <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
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>
- 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're 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-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've transferred files from Atari machine without proper file name conversion (e.g. by zipping them on Atari and unzipping on PC).
- --acsi <id>=<file>
- Emulate an ACSI hard disk with given BUS ID (0-7) using image <file>. If just filename is given, it's assigned to BUS ID 0.
- --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>
- -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)
- --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)
- --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.
- --rtc <bool>
- Enable real-time clock
- --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.
- --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.
- -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.
- Toggle XBios command parsing. Allows Atari programs to use all Hatari functionality and change Hatari state through Hatari specifit XBios(255) calls. XBios(20) printscreen calls produce also Hatari screenshots.
- --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>
- Save Hatari configuration and exit. Hatari UI needs Hatari configuration file to start, this can be used to create it automatically.
- 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
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:
- 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.
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
- toggle between fullscreen and windowed mode
- activate the hatari options GUI
You may need to hold SHIFT down while in windowed mode.
- 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.
- 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.
- 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.
Files and Directories
- /etc/hatari.cfg (or /usr/local/etc/hatari.cfg)
- The global configuration file of Hatari.
- The (default) directory for user's personal Hatari files; hatari.cfg (configuration file), hatari.nvram (NVRAM content file), hatari.sav (Hatari memory state snapshot file which Hatari can load/save automatically when it starts/exits), hatari.prn (printer output file), hatari.wav (recorded sound output in WAV format), hatari.ym (recorded sound output in YM format).
- /usr/share/hatari/ (or /usr/local/share/hatari/)
- The global data directory of Hatari.
- The TOS ROM image will be loaded from the data directory of Hatari unless it is specified on the command line or the configuration file.
