Et quelques nouveautés et corrections :
Major highlights of this new version:
– Major rewrite of the internal delays/timers, speed up emulation by ~10% on average
– Various CPU improvements (FPU, IPL timing)
– Faster CPU emulation for 68000 in cycle exact mode (speed up emulation by ~7%)
– More accurate MFP emulation, combined with the new internal timers
– Improved VBLANK position in 50 and 60 Hz mode
– Improved cycle accurate YM2149 emulation, supporting new effects (syncsquare in maxYMiser v1.53)
– Better value for MFP GPIP bit 7 (STE DMA sound and Falcon sound)
– For SCSI, improve « Mode Sense » and « Report Luns »
– For IKDB, better emulation of commands $A and $B
– Better MIDI using PortMidi (Linux/Windows/macOS)
– Better RS232 support for BSD/macOS
– Some fixes for Gemdos HD mode
– Many debugger improvements
– Hatari now defaults to the SMALL_MEM build option, using less RAM during emulation
 

Following features are deprecated and will be removed in a future release:
– SDL 2.x « bUseSdlRenderer » config and « GPU scaling » GUI options (after HW support for SDL2 is available widely enough)
– The « external » disassembler (i.e. use « –disasm uae » instead)
– Hatari XBios(255) API enabled with the « –bios-intercept » option (i.e. use « –natfeats » & « –cmd-fifo » options and « hconsole » instead)
– The old ~/.hatari configuration file location (use ~/.config/hatari instead)
– The rendering functions for 16 bits-per-pixel host screens (almost all recent hardware should have 32 bpp nowadays)
 

Removed features (that were marked as deprecated in earlier releases):
– Support for the SDL 1.2 library (i.e. SDL 2.x should be used instead)
– Support for building Hatari for Windows CE has been removed, too, since this was relying on version 1.2 of the SDL library.
– The old UAE CPU core (i.e. the new WinUAE CPU core is now always used)
– Python v2 support in Python scripts (Python 2 was end of life in 2020)
 

Emulation improvements:
– Internal timers:
*Rewrite the internal timers used to emulate delays/events/mfp timers (gain ~10% on average, up to 60% in very specific cases)
– CPU:
*Improve FPU emulation (exceptions, unimplemeted instructions, fsincos)
*Improve FPU emulation in softfloat mode
*Improve IPL timing update in various opcodes
*Faster emulation of 68000 in cycle exact mode (gain ~7%)
– MFP:
*Use the new internal timers for MFP timers
*Improve accuracy when reading MFP’s Timer Data Register
*More accurate emulation by processing all internal timers first before reading/writing any MFP register (was previously delayed after processing the current CPU instruction, which was too late in some cases)
– Video:
– Fix position for detecting when VBLANK should be disabled in 50 Hz and 60 Hz
– DSP:
*Improved interrupts handling and SSI (from Previous NeXT emulator)
– Sound:
*Improve accuracy of YM2149’s sample generation by using the main CPU clock as a reference for all timings (syncsquare effect as used in recent maxYMiser v1.53)
*Use specific memory functions when doing DMA for STE and Falcon sound (don’t generate bus error when pointed memory is not present)
*Improve value of MFP GPIP bit 7 for DMA sound in the case of STE/TT
(video mono XOR dma sound xsint)
*Use 2 different signals SOUNDINT and SNDINT for Falcon (connected to MFP GPIP7 and MFP Timer A input)
– FDC:
*Stall the CPU during 32 cycles when DMA FIFO is filled/transferred
– SCSI:
*Improve MODE SENSE, add REPORT LUNS support
– IKBD:
*support deltax/deltay in command $A (set mouse keycode mode) and threshold x/y in command $B (set mouse threshold)
 

Emulator improvements:
– TOS support:
*Support 1024k EmuTOS images also on TT & Falcon
*Add country code option to select EmuTOS language, keyboard layout and screen refresh rate on Mega/ST/STe machines (ones lacking NVRAM)
– MIDI support:
*Fix: PortMidi rejects Hatari MIDI events
*Fix: MIDI IRQ needs to be re-enabled on MIDI device change even when there’s no reset
*Support for matching PortMidi device name by prefix when there’s no exact full match
– RS232:
*The RS232 receiver code has been rewritten to use polling instead of using a thread. This should avoid deadlocks on BSD/macOS systems when shutting down or reconfiguring the RS232 settings.
– TT/Falcon:
*Increase max TT-RAM amount to 1024 MiB
*Separate config + CLI options to override NVRAM language and keyboard layout settings
*NVRAM language default is taken from the LANG env variable
– Falcon:
*Fix: restore zoom mode correctly when loading snapshots
*Correct also smaller specified memory amounts to valid ones
*Microphone emulation now uses SDL2 instead of PortAudio
– MegaSTE/TT:
*Add VME/SCU registers « –vme  » access option (Linux needs « none » option and TOS v2 / v3 need « dummy » one until Hatari implements real VME/SCU register emulation)
– VDI mode:
*Relax VDI mode width alignment from 128/planes to 16/planes, and height alignment from 16 to 8 pixels
– SDL GUI:
*Fix: ignore unrecognized events in file selector (buttons could be incorrectly shown as selected)
*Fix: avoid key release event from SDL GUI closing leaking to emulation
*Do VDI mode size changes in (faster) 16 pix increments, and prevent user seeing invalid VDI mode sizes
*Fine-tune CPU dialog texts and keyboard shortcuts
– GEMDOS HD:
*Fix: clear GEMDOS Fread / Fwrite errors
*Fix: Allow GEMDOS tasks to use other tasks’ file handles
– Command line:
*Support « off » as alias for « none » when disabling DSP, FPU, Joysticks and VME, for consistency with HW on/off options
– NatFeats:
*Fix: freeze with NF_STDERR when string is empty or unterminated
– Debugger:
*Fix: profile header so that profile data post-processor knows how to parse built-in WinAUE CPU core (« uae ») disassembly output, not just « ext » disassembler output
*Repeat CPU & DSP « step » and « next » commands on Enter
*Output PC location in CPU & DSP disassembly
*More readable « variables » command output
*Add « PConSymbol » variable for breaking on symbol addresses
*Add « mmu » and « vme » options for « info » command
*Add « scc » and « vme » (VME/SCU reg access) tracing support
*Setting trace to « none » disables also xconout console output enabled by « os_base » trace option
* »next subreturn » will run until current function returns, even if function calls other functions before that
*Symbol loadind code is now shared between debugger « symbols » command & « gst2ascii » tool, and it can now read also long symbol names from Pure-C debug information
*Auto-detection for whether section offsets should be used when loading symbol information
*MIDI trace options are split to « midi » (device & MIDI events) and « midi_raw » (IRQ and register read/write access). Trace logging added also for MIDI byte writes, not just reads
*Trace options are listed in alphabetical order
– Windows:
*Next/prev drive change buttons added to SDL GUI file select dialog
