Hatari v1.9.0 (2015/09/11) is released. Hatari is an Atari ST/STE/TT/Falcon emulator for GNU/Linux, BSD, BeOS, Mac OS X and other systems that are supported by the SDL library. The Atari ST was a 16/32 bit computer system which was first released by Atari in 1985. Using the Motorola 68000 CPU, it was a very popular computer having quite a lot of CPU power at that time. Unlike many other Atari ST emulators which try to give you a good environment for running GEM applications, Hatari tries to emulate the hardware of a ST as close as possible so that it is able to run most of the old ST games and demos. Hatari is open source software and is distributed under the terms of the GNU General Public License (GPL).

Hatari v1.9.0 Changelog:
Emulation:
- STE Joypads:
- Fix: Joypad A Option button
- Fix: Joypad B extended buttons
- ACSI / IDE:
- Fix: image file attribute check when using device files
- Fix: v1.8 ACSI regression with A1=0 case
- GEMDOS HD:
- Fix: matching exactly 8 chars long file names containing '.'
- Better mapping of host errors to GEMDOS error codes
- Support for mapping file names with 8-bit characters
between host and Atari encodings (umlauted chars etc)
- Program header (TT-RAM) allocate flags support
- CPU:
- update WinUAE CPU core version from 2.3 -> 2.8.1 -> 3.0 -> 3.1
- MMU emulation fixed
- instruction/data cache emulation
- better 68020/30 prefetch pipeline
- cycle accuracy, etc.
- in 68000 mode, remove some un-allowed for CMPI, BTST and TST
- check for address error when new PC is set at the end of RTE, RTS and RTR
- fix "move.b an,", it's not allowed and should give illegal instruction
- improve stack frame for bus error and address error
- allow bus control only for 030
(i.e. prevent TOS forcing 16Mhz at boot with higher CPU levels)
- Memory:
- TT-RAM / 32-bit addressing support both for TT & Falcon emulation
(when using EmuTOS, this requires version 0.9.4 or later)
- FDC changes:
- for STX disks, fix type I commands with verify bit on tracks with no sector
- for ST/MSA, check read address and read track are not beyond max track
- MFP:
- better emulation of GPIP, AER and DDR
- MIDI:
- some RX/TX interrupt conditions were not correctly handled
- TDRE bit is status register more accurately handled
- Video:
- fix value when reading video counter $FF8205/07/09 in high res
- Blitter:
- when transfer ends, hog bit should be cleared in control register
- DSP:
- better emulation of the HREQ signal

Emulator:
- Support for compiling with libSDL2 (experimental)
- SDL2 supports other than 2x scaling factors for ST/e emulation
- Misc fixes:
- Fix: WinUAE CPU core (FPU) memory state restore
- Fix: chrash with VDI extended resolution emulation when
C: isn't GEMDOS HD emulated drive
- Fix: invalid defaults for real joysticks
- Fix: compilation when zlib is missing
- Fix: bugs from Debian bug tracker:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=716536
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=688594
- Additional TOS run-time patching:
- Support fast boot also with TOS v3 & v4
- Support 32-bit addressing also with TOS v4
- Replace TOS v4 instructions unsupported on 060
- HW specific phystop value in VDI mode
- Options:
- Fast boot (warm boot / memory check bypass) is disabled by default
- 68060 CPU level and --ttram support with new WinUAE CPU core
- New --png-level option to decrease AVI compression CPU load
- Mouse warping on reset & resolution change can be controlled
with new --mousewarp option
- Hard drive emulation:
- BUS ID for ACSI drive can be specified with --acsi
- GUI and command line options to enable 8-bit file name
Atari <-> host charset conversion for GEMDOS HD
- GUI and command line options to specify GEMDOS HD emulation drive
(default = C:), or to skip recognized drives used by partitions
on ACSI & IDE images
- Partition count parsed by Hatari might not match count used by
Atari HD driver due to driver differences in interpreting disk MBR
- Refuse to mount same HD image from multiple Hatari instances
(on platforms supporting BSD flock()), to avoid corrupting them
- SDL GUI:
- joystick navigation in options GUI
- keyboard navigation & shortcuts in options GUI
- sort file selector items case-insensitively with folders first
- Partial support for showing Latin1 chars from UTF-8 file names
- AltGr+F<1-4> keyboard shortcuts to switch mode/type for emulated
joysticks and joypads
- User can reset or quit emulation from CPU halt dialog
- Fix: sync joystick changes with statusbar
- Fix: update default max window size for 2-line statusbar
NOTE: size would need to be updated in Hatari config files too!
- Fix: statusbar assert when FPU/MMU/TT-RAM are enabled in WinUAE CPU core
- When cpu enters 'halt' state in case of double bus/address errors,
show a dialog window to reset or call the debugger
- Fix bug in the filesector dialog that could create bug in other
dialogs used in Hatari
- Debugger:
- Fix: crash when GEMDOS tracing is used without GEMDOS HD emulation
- Fix: update external disassembler's CPU mask when CPU type is changed
(it wasn't restricted to opcodes valid for given CPU type)
- Fix: breakpoint addition/removal within chained breakpoints
- Fix: Atari program detection on Windows for "symbols" command
- Profiler support for TT-RAM (uses *ton* of memory)
- Profiler support for (030) data cache and new "profile caches"
command to show i/d-cache hit/miss histograms
- Add trace support for IDE, MIDI and keymaps. ACSI (SCSI) and IDE
trace output shows primary partition tables for ACSI & IDE images
(both Atari and DOS MBRs are supported)
- Add "os_base" trace option to trace Fopen/Fclose/Pexec/Pterm*.
That and "os_all" will now enable also xconout console redirection
- Output from --conout goes now to stdout instead of stderr
- Add "reset " command
- Add "save" subcommand to "history" command
- Add "basepage" address variable

Other changes:
- Add script to convert long host file names to Atari file names,
use that in atari-hd-image script
- Add hatari-prg-args script for providing arguments to autostarted programs
- Fix Atari program detection on Windows in "gst2ascii" tool
- Hatari & disk image icons in SVG & PNG formats (multiple sizes)
- Remaining Hatari OSX UI changes for Hatari v1.8.0 (localization)
- Add video-recording.txt doc on video recording/uploading best practices

Fixed demos:
- Graphix Sound 2 in Relapse by Cybernetics (blitter+cpu, bus arbitration)
- RGBeast by Aggression (video, writing to video counter during active display)
- My Socks Are Weapons by Legacy (video, reading video counter in high res)

Fixed games:
- Superior 65 - Blood Money (cpu, exception stack and bus error)
(note that this version is bugged and will crash with TOS 1.04 or 1.62)
- Obitus (STX version) (fdc, seek+verify on a track with no sector)
- The Teller (STX/CTR version) (cpu, exception stack and address error)
- War Heli (cpu, exception stack for address error and prefetch)

Fixed programs:
- Realtime and M by Eric Ameres (midi + mfp, toggle bit 0 of AER)
- Notator (midi, more precise TDRE bit in status register)

Known regressions (see compatibility list):
- Suretrip demo by Checkpoint
- Golden Island game demo with WinUAE CPU core
