Der Atari ST Emulator für Unix/Linux, RiscOS, BSD, BeOS, Nokia N770 / N800 internet tablet, Solaris, AmigaOS, Mac OS X und Windows Hatari ist in einer neuen Version erschienen.

A new version of the Atari ST emulator for Unix/Linux, RiscOS, BSD, BeOS, Nokia N770 / N800 internet tablet, Solaris, AmigaOS, Mac OS X and Windows Hatari has been released.

Hatari 1.7.0 has been released. You can download it from http://download.tuxfamily.org/hatari/1.7.0
Thanks to all the people who contributed to this version with code, ideas, bug reports. Let´s keep on improving Hatari !

  • Experimental MMU for the 68030 mode
  • Improved IKBD/ACIA : full ACIA emulation (timings, serial link, registers)
  • Much more accurate MFP : simultaneous interrupts, delayed IRQ, IACK cycles
  • IACK cycles for CPU´s exceptions (HBL and VBL)
  • FDC : better GAPs´ timings, angular speed/position used when accessing data
  • TT video emulation, with better video modes
  • Bug fixes for Gemdos HD emulation
  • Some changes to the SDL UI (fileselector, drive LED)
  • Lot of improvements to the debugger and to the profiler (CPU and DSP)

Release Notes Version 1.7.0 (2013-06-24)


TT video emulation:
  • Extend the ST palette registers from 9bit to 12bit for ST modes
  • Duochrome mode instead of monochrome for ST High
  • Implementation of SampleHold in TT Hypermono video mode

Sound changes:
  • Better model of the YM2149 noise generation (no noticeable audible impact)
  • Slightly better volume table (measured by Paulo Simoes on a real ST)

CPU changes:
  • Added experimental MMU emulation for the 68030 mode
  • Handle the IACK cycles during an exception for HBL/VBL

ACIA/IKBD changes:
  • Full implementation of the MC6850 ACIA, giving much more robust IKBD emulation
  • Better timings for all IKBD commands (measured on a real STF)
  • Clock is handled internally in IKBD, host date/time is used only to initialize RTC at boot. I.e. pausing emulation doesn´t cause time skips when unpausing
  • Fix slow mouse when absolute mode is used with scale values

MFP changes:
  • Fixed priority errors when simultaneous interrupts happened
  • MFP´s IRQ should be delayed by 4 cycles before reaching the CPU
  • MFP´s IRQ signal was not correctly updated in some cases
  • Handle the IACK cycles between CPU and MFP during an exception

FDC changes:
  • Better delays for all the GAPs inside a track
  • Emulate the disk´s rotation and its angular position to get accurate delays when accessing a sector header
  • Internal timer for FDC was wrong and sometimes slower than expected
  • Correct delay for type I commands with "verify" bit=1

GEMDOS HD emulation changes:
  • Support Fforce() for GEMDOS HD emulated files and close at Pterm*() all internal handles to emulated files program had left open
  • Fix: cut file and dir names to 8+3 chars like all TOS versions do
  • Fix: GEMDOS HD emulation overwrote last 28 bytes of basepage space for the started process command line (with the program header)
  • Fix: Fwrite() content wasn´t flushed to disk on each write, so later Fopen() + Fread()s calls on such files (if they were not closed in the meanwhile) could get data that was out of date.
  • Fix: Dfree() return value


  • Fix: problems with run-time CPU type changing
  • Fix: MIDI IRQs were not enabled if MIDI was enabled at run-time. MIDI toggling will now imply reset
  • Much improved console redirection functionality and a separate --conout option for it (--bios-intercept doesn´t anymore imply console redirection)
  • Fixed a bug with the axes´ mapping in the joystick´s detection

Display handling:
  • Fix: max resolution limit wasn´t handled properly for ST mode.
  • Don´t change TOS-calculated font size for VDI mode.
  • Setup NVRAM video mode based on VDI mode, when in VDI mode. This makes VDI mode work with EmuTOS also under Falcon emulation which is useful as EmuTOS doesn´t support native VIDEL expanders
  • Limit VDI screen memory usage to 300kB, this allows upto 2048x1200 monochrome and 1024x600/800x768 16-color VDI screens

GEMDOS HD emulation:
  • Fix: to DTA host filename cutting to 8+3 chars when whole filename was < 12 chars (caused EmuTOS crash)
  • Give warning if GEMDOS dir/file path exceeds 8+3 characters (as those won´t work with real TOS)
  • New --gemdos-case option to specify whether new dir/filenames are forced to be created in upper (default) or lower case
  • Giving empty string as GEMDOS HD dir disables GEMDOS HD emulation

  • Fileselector has "CWD" button for changing to Hatari´s work directory
  • Fileselector remembers previous position which is nicer with large directories
  • Make the drive leds blink with a brighter green when the FDC is executing a command

  • Fix: profiler assert on invalid PC register values
  • Fix: profiler usage in debugger files invoked by breakpoints
  • Fix: profiler CPU & DSP cycles information is for previous instruction
  • Fix: WinUAE CPU requires cycles counter usage for getting current CPU instruction cycles
  • Profiler provides timing information, based on used cycles
  • Profiler provides CPU instruction cache misses information when using cycle-exact WinUAE CPU core (which is Falcon emu default)
  • Profiler top instruction count/cycles/misses lists show the related instructions
  • For DSP, profiler adds min/max cycle difference info to disassembly
  • New "addresses" subcommand can be used to see addresses through which code passed during profiling (e.g. while program seems frozen, this gives much better overview of code that is being run, than cpu trace)
  • New "callers" subcommand lists all addresses from which loaded symbols´ addresses were "called" from. This way one can e.g. find in which contexts interrupt handlers were called and it can be used to construction program execution callgraph
  • New "save" subcommand saves profile address and caller information to given file, with extra information needed for post-processing
  • New "stack" subcommand that can be used to get backtraces during profiling with symbols, for ´:noinit´ backtraces

  • New ´:noinit´ and ´:quiet´ breakpoint options. Quiet option removes most of breakpoint matching "noise" and ´:noinit´ breakpoints can be used with "profile stack" command, to prevent profile data and related callstack information from being reseted on breakpoint match
  • "blitter" and "dsp" subcommand added to "info" command, to show blitter register values and DSP state (e.g. stack content)
  • "prg" subcommand added to "symbols" command, for loading debug symbols from DRI/GST symbol table in last started program
  • "step" and "next" commands added for single stepping CPU and DSP code -> ´s´ shortcut is now for "step", not "save"
  • "--disasm" option for selecting between UAE core and external CPU code dissassembler and setting output option flags for latter
  • When -D option is used, also undefined/illegal DSP instructions and DSP stack under/overflows invoke debugger, not just CPU issues
  • Fix: when several breakpoints should have triggered on the same address, only first was handled
  • Fix: after breakpoint, ´c ´ continues one instruction too little
  • Fix: tracking breakpoint values were updated only when all conditions matched, now they can be also used together with other conditions
  • Fix: info command crash (triggered on NetBSD)
  • Fix: disassember output bug on NetBSD (usigned char < -1 test)
  • Fix: info osheader and basebase subcommands under MiNT
  • Fix: debugger history duplicates removal
  • Fix: expression expanding CPU "pc" for DSP shortcut commands
  • Fix: expression expansion messing lines in command line history
  • Remote API debugger commands can also use expression expansion
  • Both single and double quotes can be used to mark expressions
  • In addition to text section offset, data and bss section offsets can be given when loading symbols (useful for Devpac symbols)
  • Output what value was set by options if it´s not otherwise shown by UI
  • New ´cpu´ and ´dsp´ options to ´history´ command for tracing just one of these processors on Falcon
  • Function arguments are shown in traces for all non-MiNT GEMDOS calls and subset of arguments are now shown also for AES calls (values in intin array and strings in addrin array)
  • Add NVRAM read & write tracing
  • Support for the basic Native Features and --natfeats option to control it:

Windows specific changes:
  • "-W" option added for opening a console window. Like on all other platforms,
    "-D" will now just toggle CPU exception handling
  • Fix: console stderr redirection (used invalid "wr" mode)
  • Fix Windows localtime() not supporting dates before 1970:
    TOS not being able to access files with such dates, or further files
    causing IKBD emulation crashes (wasn´t problem with Cygwin, just with Mingw builds)

Tool updates:
  • New hatari-profiler.py script for post-processing output from profiler´s CPU and DSP profiling "save" commands:
    profile save
    dspprofile save
    With symbol address information it can provide function level instruction, processor cycle & i-cache miss statistics
    With callers information it can create function call callgraphs and create callgrind format files for Kcachegrind GUI
  • New gst2ascii tool to extract DRI/GST symbol table from Atari program, for use with the profile data post-processor
  • Added scripts for converting symbol tables in Devpac 3 listings and DSP LOD files to a format understood by Hatari debugger ´symbols´ command, and to clean ´nm´ output of GCC & VBCC built a.out binaries for it

Other changes:
  • HTML documentation indeces generated dynamically with JS
  • Debugger tests building fixed

Fixed Games:
    Atomix (MFP, flickering bottom of the screen during samples)
    BBC 52 Menu (Video/CPU, top border not removed)
    Bolo (MFP, couldn´t start a game)
    Captain Blood (IKBD, fixed problem when setting the clock)
    Fokker and Downfall (ACIA/IKBD, had regressed in Hatari v1.6.x)

    The Final Conflict (MFP, locked during the sampled intro music)
    The Sentinel (IKBD, mouse much too slow)
    Zuul 100/101 Menu (MFP, flickering top border)

Fixed demos:
    Anomaly Demo Main Menu by MJJ Prod (MFP, flickering top/bottom borders)
    Audio Artistic Demo by Big Alec (MFP, bad sample speed at start)
    Decade Demo - Reset (MFP, flickering bottom border)
    High Fidelity Dreams by Aura (MFP, flickering left rasters)
    ST-NICCC 2000 Demo by Oxygene (FDC, demo ran slower than expected)

Fixed apps:
    Monst v1.x
    Spectrum 512 (IKBD, mouse too slow)
    Cubase (when MIDI was enabled after Hatari startup)
