worst frame and spinloop profiling
- Address space in 'dm' command can be given like in DSP disassembly,
"dm x:$100", in addition to earlier "dm x $100" syntax
- Fix out of bounds memory access that could result in bad disassembly
output when using the external disassembler (only "dc.w" were printed)

was the standard deviation of that.
- gst2ascii supports now both section relative and TEXT section relative
DATA/BSS symbol offsets

Version 1.7.0 (2013-06-24):
---------------------------
Emulation:
- 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in the meanwhile) could get data that was out of date.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
Emulator:
- 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 up to 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
- SDL GUI:
- 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
- Profiler:
- 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
- Debugger:
- 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 reset 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 <n>' 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:
http://wiki.aranym.org/natfeats/proposal
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 <filename>
dspprofile save <filename>
- 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

Version 1.6.1 (2012-01-13):
---------------------------
This version is mainly a bugfix for 1.6.0, where monochrome mode
gave a black screen and was not usable.
Emulation:
- Fixes to bootup issues in monochrome mode
- Better left border removal timings
- DSP external memory access cycles taken into account
Other changes:
- Fix to allow build with Xcode 3.1.3/OS X 10.5.8 PPC

for them to work correctly with Hatari v1.6.x
- Test programs added for testing TOS booting with different
HW configurations and for finding out values needed in
Hatari keymaps
Fixed Demos :
Vodka Demo - Kill The Beast 2 (left border removal)
Version 1.6.0 (2012-01-01):
---------------------------
The Hatari project has been moved from hatari.berlios.de to
http://hatari.tuxfamily.org/. Please update all bookmarks!
Emulation:
- More accurate FDC emulation (correct status bits and commands' timings,
DMA transfer by blocks of 16 bytes, floppy change detection). This should
fix a lot of non working games
- More accurate microwire clock emulation
- SCSI class 1 (ICD) command support for drives > 1 GB
- Improved color conversion table so that colors are a little bit brighter
- Improve shifter (add another method to do 4 pixel hardware scrolling,
better emulation for 0 byte blank line)
- Some fixes to the IKBD emulation
- Better filters and model for sound emulation
- Correct VBL timings in TT monochrome (double clicking works now)
- More cycle accurate Falcon DSP <-> CPU emulation. All the demos that
needed 32Mhz CPU with the old CPU core in Hatari v1.5, work now at
correct 16Mhz with the WinUAE CPU core
- 030 MMU emulation with the WinUAE CPU core
Emulator:
- Switch to ST mode when using TOS <= 1.04
- Replace "--slowfdc" with "--fastfdc" option and default to fast FDC being OFF
- "--fast-boot" option to initialize "memvalid" system variables to
by-pass the memory test of TOS, so that the system boots faster
- "--force-max" option to force Hatari use specified maximum resolution
to avoid window size changes messing up Hatari video recording
- "--desktop-st" option to keep desktop resolution also for ST/STE modes
(unfortunately without scaling besides the low-res doubling)
- GEMDOS HD emulation:
- Allow drives up to Z: (not Y:)
- Unique name for each partition
- Warn user when using too old TOS version
- Dfree() reports host disk total and free size if they're below
value understood by TOS and unlike earlier, it forwards Dfree()
requests for other (IDE/ACSI image) partitions to TOS
- Debugger improvements:
- "history" command to list instructions executed before entering
debugger
- each trace output line is flushed to avoid it being buffered
- Fixed behavior of the Caps Lock key
Other changes:
- Fixes to Hatari UI Hatari window embedding
- Latest Linux sfdisk is borked so atari-hd-image script creates
HD image partition table now itself (experimental)
- Windows needs also HOMEDRIVE for full home path in case Hatari
isn't installed on C:, bug 18297
- Minor fixes
Fixed Demos :
Overscan Demos and Shforstv.exe by Paulo Simoes (black line at top),

Fuzion 102 - Exile, PP46 - Yolanda, Medway Boys 15 - Murders In Venice,
Medway Boys 83 - Yogi Bear, BBC 2 - Platoon, BBC 39 - The Deep, Superior 71 - The
Running Man, Adrenaline 24 - Demon Blue, Superior 93 - Alien Storm
Fixed Misc Programs :
Procopy 1.50, Terminators Copy 1.68, maxYMizer (caps lock key)
Version 1.5.0 (2011-07-19):
---------------------------
Emulation:
- Alternative CPU core based on WinUAE for more accurate future
HW interaction emulation (see readme.txt on how to enable it)
- Use precise clocks values (as described in Atari's official schematics)
for better video/dma audio synchronisation (e.g. More Or Less Zero by DHS)
- DSP:
- Some DSP-timing sensitive Falcon demos that by luck happened to work
with Hatari v1.4, don't work anymore in v1.5 with the default UAE CPU
core. This is because while DSP cycle accuracy has been improved,
the default UAE CPU core isn't fully cycle accurate. The experimental
WinUAE core is needed to run them
- Undocumented 2 bit shift special case for DSP SSI <-> crossbar exchanges
in hanshake mode with 32 Mhz clock (fixes DSP MP2 player used in many
demos & programs, but that requires also using WinUAE core)
- Sound improvements:
- Major rewrite and accuracy improvements in STE DMA sound, including
emulation of the 8 bytes FIFO, giving results nearly identical to
a real STE (e.g. HexTracker by Paulo Simoes)
- Improved precision in sound emulation, with nearly no rounding errors
over successive VBL (correct sound latency on US TOS running at 60 Hz)
- By default mix 3 YM voices using a lookup table of values
measured on real STF to improve digisound (e.g. Flashback demo sound)
- Remove old ST Sound's code used for tone and noise step compute
(some low period values were not correctly emulated)
- Video emulation on STF/STE:
- On STE, correctly shift display 8 pixels to the left when using
224 bytes overscan
- Add support for spec512 mode in med res (fixes 'Best Part Of The
Creation' in 'Punish Your Machine', 'HighRes Mode' demo by Paradox)
- Correctly shift the screen 4 pixels to the left when left border is removed
in med res overscan (Hatari 1.4 handled only low res, fixes 'No Cooper'
by 1984, 'Best Part Of The Creation' by Delta Force)
- Precisely emulate the number of frames per sec (eg 50.053 fps in PAL
instead of the usual 50 Hz)
Emulator:
- Atari program given as argument to Hatari will be automatically
started after TOS boots. GEMDOS hard disk directory can now be
give also as an argument, not just as a (-d) option
- TOS4 or --machine falcon option use enables DSP emulation now
(follow them with --dsp none to disable DSP emulation)
- Memory state saving and restoring fixes, especially for Falcon
- Crossbar state is included -> state file ABI break
- AVI recording options can be set in the new [Video] config file section
- AVI recording supports non integer frame rates.
- Falcon/TT Videl/hostscreen improvements:
- New setting/option for using Desktop resolution & scaling
in fullscreen instead of changing the resolution. On by default
- User's desktop size is used as max limit for Videl zooming.
Requires SDL >= 1.2.10
- Videl resolution change is done immediately, not 3 VBLs late
- Fix issues in switching between same sized VDI & TT resolutions
- SDL GUI improvements:
- DSP can be disabled from the GUI without needing to restart Hatari
- Disk access LED and desktop-resolution options
- AVI video length (mins:secs) is shown in titlebar during recording
- Option for cropping statusbar from videos & screenshots
- Fileselector scrollbar can be used with mouse
- YM mixing method selection
- Debugging improvements:
- New disassembler with more Motorola like syntax
- CPU & DSP "disasm" and "memdump" commands accept register & symbol
names in addition to numeric addresses / address ranges
- Option to disable Falcon mic
("--mic off" is needed for Mudflap debugging)
- "--run-vbls" can be set also at run-time
- "--bios-intercept" can be toggled from debugger (not just enabled)
- BIOS CON: output is converted to ASCII and redirected to host console
with the --bios-intercept option
- Support for tracing DSP, Videl and Crossbar
- Support for tracing AES calls. VDI calls can now be traced
also without using an extended VDI resolution
- BIOS/XBIOS/GEMDOS/VDI/AES/Line-A/Line-F opcode breakpoint support
- TEXT, DATA and BSS variables for addresses of corresponding segments
in currently loaded program
- "aes", "vdi" and "gemdos" subcommands for "info". Without arguments
they will output information about corresponding OS part state,
with (a non-zero) argument, opcode/call name table is shown.
"video" subcommand for showing video related information.
"cookiejar" subcommand for showing cookiejar contents.
- "file" subcommand to "lock" that executes debugger commands from
given file when debugger is entered (or ":lock" breakpoint is hit)
- ":lock" option to breakpoints that will show (without stopping the
emulation) the same output as what's shown on entering the debugger
- ":file" option to breakpoints that executes the commands from
given file when the breakpoint is hit. This can be used to chain
debugger actions
- multiple breakpoints options can be specified per breakpoint
- parenthesis in "evaluate" command are used to indicate memory
accesses (instead of operator precedence like earlier)
- DSP and CPU code profiling functionality. Provides statistics about
profiled code (executed code address ranges, max and total counts
and cycles), lists addresses/instructions taking most cyles and if
symbols are loaded, what were the most used symbol addresses.
- Profiling information is also shown in disassembly output
Other changes:
- hmsa tool can create empty disk images in addition to converting
disks between ST & MSA formats
- Minimal hatari-tos-register.sh Linux init script (example)
to register Hatari as binfmt_misc handler/runner for TOS programs
- hatari-console.py renamed to hconsole.py, documented and made extensible
(hconsole is command line Python interface for Hatari remote API)
- Support for plain Makefiles removed (except for internal tests),
only CMake is used for configuring and building Hatari
- CMake doesn't require anymore working C++, C-compiler is enough
Version 1.4.0 (2010-06-12):
---------------------------
Emulation:
- IDE improvements:
- Support for second drive (IDE slave)
- WIN_FORMAT command (allows HD Driver to format IDE drives)
- GEMDOS HDD emulation:
- Minor fixes to Fseek(), Fopen(), Fdatime() (e.g. Pure debugger works)
- On TOS v4 Fread() size arg is unsigned, on earlier TOS its signed
(bad code can use -1L to read whole file instead getting fail on TOS4)
- Prevent DTA and read/write functions accessing invalid memory areas
- Programs can now change read-only files to be writable
- Falcon sound emulation:
- Microphone (jack) emulation in Falcon mode (requires portaudio library)
- SSI direct sound entrance ("Audio Fun Machine" and winrec are working)
- DMA sound recording
- Crossbar handshake mode transfers
- Max VDI rez increased to TT-hi size (1280x960)
- 68020+FPU changed to 68EC030+FPU (no MMU 030) for Falcon and TT modes
(Some Falcon programs didn't work with 020)
- Video emulation on STF/STE:
- correctly shift the screen 4 pixels to the left when left border is removed
- add support for STE's 224 bytes overscan line without stabilizer
- when reading $ff8205/07/09 on STE, take into account the value
of horizontal scrolling/prefetch and linewidth
- when writing to $ff8205/07/09 on STE, correctly handle the case
where the write is made while display in ON
- LMC1992 emulation / STE sound filtering
Emulator:
- Host mouse is centered to Hatari window on Falcon resolution changes
(helps in synchronizing host and emulated mouse positions)
- Toggling fullscreen doesn't unpause paused emulation
- Falcon/TT resolution zooming is now controlled by separate options for
monitor aspect ratio correction and maximum zoomed Hatari window size.
This can reduce Hatari window resolution size changes significantly and
makes e.g. FUN's Alive demo viewable in fullscreen mode. Limits for
window size are also checked to see whether ST/STE low rez should be
zoomed and how much of borders can be shown (when borders enabled)
- Split the Screen dialog into two separate dialogs, one for Atari
monitor emulation setup and one for Hatari window setup
- GEMDOS drive emulation:
- support long host directory names and much improved long filename support
- convert host filename chars invalid in TOS to valid ones ('@')
- use TOS filename matching instead of glob() (can match names with [])
- Options for preventing floppy image (--protect-floppy) and GEMDOS
emulated drive directory (--protect-hd) modifications
- AVI file recording:
- video can be stored as BMP or as PNG images
- audio is stored as 16 bits stereo PCM
- Statusbar shows CPU type & speed
- Can create blank 2.88MB (ED) and 1.44MB (HD) floppy images
from the GUI in addition to DD & SD images. After creating
new floppy image, one can directly insert it to A: or B:.
- Tracing for BIOS, XBIOS, GEMDOS and VDI traps gives in addition
to the opcode, also the name of the corresponding OS function
- Major debugger improvements:
- TAB-completion for debugger commands, command arguments and
symbol names. Requires readline library
- "parse" command and --parse Hatari command line option to
execute debugger commands from a file
- "stateload" and "statesave" commands for memory snapshots
- "trace" command for tracing what the emulated code does
- "symbols" command for loading and listing CPU & DSP code & data
symbols/addresses. Code symbols are shown on CPU & DSP disassembly
and code & data symbols can be used in breakpoints
- "evaluate" command for doing calculations. Register and symbol
names in expressions are replaced by their values. '$' will be
TAB-completed to last 'evaluate' command result
- "cd" command to change Hatari work directory
- "exec" command to execute shell commands (ENABLE_SYSTEM_DEBUG_CALL)
- "info" command for showing Atari HW and OS information
- "lock" command for setting what information is shown every time on
entering the debugger, e.g. disassembly or memdump from given address.
"regaddr" argument does that from address pointed by given register
- improved register name handling + fixed DSP reg name matching
- if both sides of conditional breakpoint condition are identical, replace
right side with current value of given expression (e.g. if it's "d0",
use current D0 value). If the comparison is for inequality ("!"),
output the value & break only when the value changes from the previous
value (not original like with other comparisons). Symbols support
- ":trace" option to trace/output breakpoint hits without breaking
- breakpoints count hits and can be optionally removed after first hit
(":once" option) or triggered only on every Nth hit (":<count>" option)
- dsp/address command is a shortcut for conditional breakpoints and its
argument can be an expression (see "evaluate" above)
- Display DSP instructions cycle timings in disasm mode (in cycles)
- Configuration options for how many lines to disasm & memdump
- Fix VBLs/s counting to work also when --run-vbls isn't used
Other changes:
- Considerably expanded debugging and hard disk sections in manual
- CMake build support, this fixes OSX building and adds support
for building Hatari in different directory from the sources
- Removed autotools usage/support, added CMake "configure" script
- Hatari remote control programs updates (see their own release notes
for details)

Please note that both new emulation modes are still highly experiemental,
some few games and demos work, but most still have more or less big
problems.
- Basic emulation of Falcon video shifter (Videl), NVRAM and DMA sound is in

- A lot of internal code cleanup and bug fixes.
- Added a dialog for creating new blank floppy disk images.
- The source code has been optimized for better emulation speed.
- Added RS232 emulation (still very experimental and not very well tested! It
seems not to work reliable yet. Help for debugging is very appreciated!).
- Some bugs in the 68000 emulation have been fixed.
- The emulator now checks for double bus errors and stops the emulation if
necessary (instead of crashing the emulator).
- Timer-D is now patched correctly again.
- The old font has been replaced by two new fonts so that the GUI now looks
better in high resolutions.
- The fonts are now linked into the executable.
- Added support for DIM floppy disk images.
Version 0.45 (2003-10-30):
--------------------------
- This is just a minor release on the way to version 0.50. It is not very
well tested, so be warned!
- New build system (with a "configure" shell script).
- A disk image destroying bug in the MSA compression function has been fixed.
- It is now possible to redirect the printer output into a file.
- Experimental MIDI output support.
- Added the possibility to save memory snap shots.
- Pending HBL and VBL interrupts are now emulated correctly (I hope).
- Some speed improvements.
- GEMDOS HD emulation now also works with EmuTOS.
Version 0.40 (2003-07-11):
--------------------------
- Support for ZIP and GZIP compressed disk images!
- Configuration file support for loading and saving the emulator settings.
- Hatari now works on machines with Sparc CPUs, too.
- Fixed a problem that slowed down the emulator in monochrome mode when using
TOS 2.06.
- Inverted monochrome mode is now supported, too (some games like Maniac
Mansion use this).
- Added Mega-ST compatible real time clock (RTC) emulation.
- The GEMDOS HD emulation has been improved (it now also works with lower-case
file names) and many bugs have been fixed there.
- Improved keyboard mapping (added mapping via PC keyboard scancode and via
reloadable mapping files).
- The screen rendering routines have been generalized (less differences between
windowed and fullscreen mode).
- Hatari can now be cross-compiled, too. You can even compile it for MiNT now.
However, it does not run very well there yet.
- Support for RAM TOS images.
- Improved memory mapping (the different memory regions should now behave much
more like on a real ST).
- Improved M68k exceptions (bus errors and exception cycle timings).
- Fixed some bugs in the extended VDI resolution mode (now it is working with
EmuTOS, too).
- Some games that poll the write-protection signal of the FDC to check for
disk changes should now be working, too.
Version 0.30 (2003-03-12):
--------------------------
- Some parts of the code accessed the SR directly to read the IPL -
however the UAE CPU core only updates the SR when doing a MakeSR() first.
So this is done in the affected code parts now, too.
- The IPL wasn't raised when a MFP interrupt occurred - fixed now.
- Full screen resolution for ST-Low can now be selected from the screen setup
dialog.
- The IKBD emulation does not longer duplicate joystick fire buttons when
a game tries to use both, joystick and mouse
- Improved audio timer function - the code should now be a little bit faster.
- Resynced Hatari's UAE CPU core with UAE 0.8.22 - this fixes some bugs in 68k
instructions like ABCD and SBCD.
- Added patches for TOS 2.05 so that this TOS version should now work, too.
- Rewrote TOS patching routine. It is much more flexible now.
- Removed 0xa0ff opcode for VDI resolutions; using GEMDOS_OPCODE now instead.
- Fixed MMU RAM size configuration bug.
- Rewrote some more screen conversion functions in C.
- When a bus or address error occurred, the PC was often not set to the
right exception handler routine. This has been fixed now.
Version 0.25 (2002-12-30):
--------------------------
- Patches for big endian systems (Spectrum 512 pictures are now working there).
- Hatari now also compiles and runs under Mac OS X.
- Blitter emulation has been added.
- There is now the possibility to save YM or WAV sounds.
- Big VDI resolutions (e.g. 800x600) are now supported, too.
Version 0.20 (2002-02-18):
--------------------------
- Added graphical user interface for configuration of the emulator settings.
- Real joysticks can now also be used to simulate the ST joysticks.
- Yet another bugfix for BeOS (lseek again...)
- Support for hard disk images.
Version 0.11 (2001-10-10):
--------------------------
- High level (GEMDOS) harddisk emulation.
- ST-Med/ST-Low mixed mode now works.
Version 0.10 (2001-08-16):
--------------------------
- Improved CPU cycles emulation.
- Added Spec512 support.
- Some keyboard shortcuts.
- Added the possibility to switch between fullscreen and window mode.
- ST Medium resolution conversion routine.
- Built-in debugger.
- Added possibility to grab screenshots.
- Sound support (not working very well yet).
Version 0.05 (2001-06-01):
--------------------------
- Joystick emulation via cursor keys.
- ST-LOW resolution conversion routine is now working on big-endian machines.
Version 0.04 (2001-05-27):
--------------------------
- Added Stefan Berndtsson's patch for big-endian machines.
Hatari now runs also with non-x86 Linux machines! Thanks Stefan!
- Rewrote the ST-LOW resolution conversion routines in C ==> ST-LOW now works!
- Added some of the WinSTon patches Paul Bates recently published
at the WinSTon BBS (Thanks to Ladislav Adamec for the hint).
- Cleaned up the source tree a little bit.
Version 0.03 (2001-04-03):
--------------------------
- Rewrote some more assembler functions. FDC emulation now works!
- SDL Keyboard code finished and included a SDL-Key -> ST-Scancode table.
- Added mouse support.
Version 0.02 (2001-03-28):
--------------------------
- Added very simple SDL support.
- Rewrote a lot of assembler functions in C (e.g. intercept.c).
- Adapted the UAE CPU. Now Hatari is able to boot a TOS 1.0x ROM, the
Desktop shows up, but no mouse and keyboard interaction yet.
Version 0.01 (2001-03-21):
--------------------------
- Made the WinSTon source code compilable with GNU-C.
- Added the UAE CPU sources.
