                                   --------
                                Release Notes

 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)


 Version 1.3.1 (2009-09-05):

- Writing to floppy disk images works now also with TOS 4.0x.
- A lot of source code clean-up and beautification.
- Monochrome mode now runs in 71 Hz, and 60 Hz color mode now also really runs
  with 60 Hz refresh rate.
- Fixed memory snapshot files (some important data has not been saved before).
- It is now possible to automatically load/save memory snapshots at start/exit.
- Fixed some bugs in the file selection dialog.
- Some minor improvements in the GUI: Improved text edit fields, "Cancel"
  buttons can now be activated by pressing the ESC key, and Hatari asks the
  user before resetting and quitting the emulator.

  very "fast" timers (Overscan Demos, ULM Demos) and requiring nearly cycle
  exact synchronisation with the 68000.
- Mostly correct wait states when accessing sound registers (add wait state for
  $ff8801/ff8803 when needed).
- Correct values of cycle counters read & write accesses for the most common

- Support for 4 pixels horizontal hardscroll on STF (ST Connexion in Punish
  Your Machine)
- Small adjustements in cycle precise color handling (spec512.c)


 Version 0.95 (2007-05-12):
 --------------------------

- This release brings you basic Atari TT and Falcon emulation!
  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
  place. The biggest drawback: There is no working Falcon DSP emulation yet.
- Screen/Shifter emulation timings have slightly been changed. Some things
  now work better, some others work worse...

  exactly the amount set up for Hatari.  Saves memory on embedded systems
  if less than 4MB is specified.)
- Re-written command-line option handling.
- (Again) lots of code const/static, type usage and indentation cleanup.
- Preliminary support for TOS 3.0x and 030 TT software that runs in ST
  resolutions and doesn't need PMMU.
- Native GUI for Mac OSX.
- ACSI emulation fixes to get HD formatting to work with AHDI 5. HD emulation
  now works quite fine with AHDI 5 (but other HD drivers are currently not
  supported).
- Joystick shortcut changed to toggle cursor emulation between ports 0 and 1.
- Keys for all Hatari shortcuts can now be configured from hatari.cfg.
- Added command line option for setting ST keyboard mapping.
- Joystick command line option requires now parameter for a port for which
  the joystick cursor emu is enabled.
- Fixed relative mouse event handling in zoomed low-rez.
- Hatari shows now more of the bottom borden (screen size is now 384x276
  instead of 384x267).
- Fixed sync delay timings - sound should now be better (e.g. on Mac OS X).
- Added basic support for compiling Hatari with MinGW.


 Version 0.80 (2005-10-12):
 --------------------------

- Support for STE hardware emulation: STE palette, STE shifter (horizontal fine
  scrolling, split screen effects), DMA sound and STE joypads.
  See the manual for a list of working STE applications/games/demos.

- Hatari now works on 64-bit host CPUs, too.
- Floppy disk images can now be set writable/write-protected in the GUI.
- Hatari can now also load a global configuration file (e.g. /etc/hatari.cfg).
- Configurable logging functions.


 Version 0.60 (2004-12-19):
 --------------------------

- Again some code cleanup and bug fixes.
- Window/fullscreen mode is now correctly initialized from the configuration
  file.
- Added --window command line option to force a start in window mode.
- Added alert boxes to show warnings, errors and information messages.
- PC mouse pointer is now better in sync with the ST mouse pointer.
- It's now possible to load an alternative cartridge image file.


 Version 0.50 (2004-07-26):
 --------------------------

- 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 occured - 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

- 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.
