Cet émulateur Atari ST a été mis à jour. Les améliorations sont les suivantes:
Removed features:
- The "--bpp" command line option and related code (i.e. the rendering functions for 16 bits-per-pixel host screens) have been removed since almost all recent hardware should support 32 bpp nowadays
Configuration changes:
- In hatari.cfg, section [RS232], rename:
*sSccBOutFileName => SccBOutFileName
*bEnableSccB => EnableSccB
Emulation improvements:
- MFP:
*When IRQ is cleared on one of the 2 ACIAs, do not clear IRQ on the MFP side if the IRQ is still set on the other ACIA
- Blitter:
*Ignore byte accesses to blitter registers defined as word only
- TT/DMA:
*Update sound FIFO on each HBL (like on STE)
- CPU:
*Sync CPU core with WinUAE CPU core 5.2 beta
*Improved 68000 cycle accuracy (IPL, STOP, TRACE)
*Fix IACK timings
*Return vector=24 if a spurious interrupt happens during the IACK sequence
*68010 DIV overflow undefined flags update
*NMI handling
*MMU/generic CPU mode autovectored interrupt support
*Fix 68060 MMU MOVEM.L (An)+, if regs contain An
*68040/060 MMU fault handler bug fix for MOVEM
*Fix FSINCOS and FMOVE.L/FMOVEM.L register in disasm
*Some softfloat fixes
*Fix stacked PC for branch/jump instructions doing a bus error
- DSP:
*Fix: effective address with modifier=modulo
*Add host interface initialisation
*Add host received data interrupt
*Improve bootstrap support
- Video:
*Add support for 4 pixel hardscroll on STF by stopping shifter with $FF8260=3 (new technique by Troed/Sync)
*In monochrome mode correctly mask the video address to 22 or 24 bit space depending on the machine type. Prevent crash in some cases when Hatari is compiled with "small mem" option
*Fix VBLANK location, should be line 308 on 50 Hz (was 307 before)
- SCC 85C30 (for MegaSTE, TT and Falcon)
*Major rewrite of most of the code, should support all modes used by TOS and EmuTOS or when accessing SCC's registers directly
*Support all serial ports as well as LAN port for MegaSTE and TT
- Joypads:
*STE joypad emulation now supports analog / paddle input, too
- FDC:
*For IPF/CTR support, caps library has a bug that resets FDC's TR and DR on warm reset (68000's reset command). We keep/restore the value ourselves
- IDE:
*Fixed emulation of the HOB (High Order Byte) of the last LBA48 value
*LBA28 capacity announcement is now correctly limited to 2^28-1
- Falcon:
*DMA sound : fix SNDINT/SOUNDINT values (0=playing, 1=idle) and interrupts on TAI / GPIP7 for start of frame / end of frame
*Preliminary support for more vertical refresh rates (50,60 or 71 Hz) based on Videl's registers $FF82C0 (VCO) and $FF82A2 (VFT) (was only 50 Hz before)
Emulator improvements:
- TOS:
*Fix: set TOS country code from CountryCode setting, not Language one
*Add "pl" (Poland) & "ro" (Romania) language options for EmuTOS
- RTC:
*CLI/config option to override NVRAM/RTC year, useful with applications that do not handle current dates
- Joystick/Joypad support:
*Fix: joystick button 2 space key emulation "autofiring"
*Keyboard emulation support for all STE joypad buttons/keys
*Support for re-mapping joystick buttons
- GEMDOS HD:
*Fix: Fread/Fwrite combination on Windows
*Fix: Frename() should fail when target exists
*Support up to 64 simultaneously open files (earlier limit was 32)
*Similarly to TOS, allow programs to write to a file they have opened as read-only (by opening all writable files as read/write). As this could fail with real HW under MiNT/MagiC, show warning about it
- Screen:
*Support for screenshot using .NEO or .XIMG format
*Add option "--screenshot-format " ( = png or bmp or neo or ximg)
- Memory Snapshot:
*Add some missing variables to the savestate
- Logging/tracing:
*"os_base" trace option outputs now also dir create/delete + file delete calls (in addition to earlier pexec/pterm & file create/open calls)
*Separate CPU video cycles under its own "cpu_video_cycles" trace flag
*Suppress repeats of identical log & trace messages by default (show only their count) and add "--msg-repeat" option to toggle that
- Debug symbol handling:
*Fix: invalid free on freeing loaded GNU debug symbols
*Fix: Do not limit "A" type (constant) symbol values to 24-bit
*Add support for reading symbols from new MINT+ELF binaries
*Add support for demangled C++/a.out symbols (which can be very long and contain almost any characters)
*".sym" file beside program file acts as its symbols override
*Add optional argument for "symbols " commands, to limit listed symbols to ones with the given substring
*Improved support for weak symbols (important for C++ code)
*Symbols with duplicate addresses are skipped on symbols loading
- Disassembler:
*Fix: CPU core disassembler crashes with longer symbol names
*When entering debugger with 'history' enabled, disassembly address defaults to an address in history preceding the PC register value (to give more context than disassembling directly from PC)
*Support for disassembly output options working also for CPU core disassembler, in addition to external disassember output
*More flags to change the disassembly output for CPU core (upper/lower case, show memory content, show EA, ...)
*The built-in "external" disassembler has been replaced by a disassembler provided by the Capstone library (version >= 4.0)
- Debugger:
*Fix: free all debugger allocations before exit
*Fix: memdump command always outputs only requested number of items
*Add address width (addr).[bwl] support to expression evaluation
*History skips address repeats (e.g. with "stop" instruction)
*Breakpoint ":quiet" option inhibits also extra output when ":file" option debugger command file is parsed
*Line-A and line-F exceptions can be caught with "--debug-except" option (in addition to breakpoints)
*Add "echo" command with escape handling, so that one can e.g. use "echo \ec" to clear (ANSI) terminal before breakpoint output from a debugger command file
GUI improvements:
- SDL GUI:
*Fix: mouse not visible in floppy disk dialog when it is invoked from a keyboard shortcut in fullscreen mode
*Fix: fileselector scrollbar works with mouse also in SDL2 scaled / fullscreen window
*Support for joystick button mapping + space key vs. jump option
- Mac GUI:
*Accept all file names as Mac file selector does not show a list of the accepted file name extensions any more
Tools:
- gst2ascii:
*Support for new MINT+ELF symbols
*"-o" option is split to "-f" and "-g" options
*"-s" option to skip symbols with duplicate addresses
*By default filters same symbols out as Hatari debugger
*This can be reverted with new '+' option variants (+l +g +s)
*More concise listing of the duplicate symbols
- Profile data post-processor:
*Does not show (most) of symbol conflict messages any more (unless '--verbose' option is given)
*When address has multiple symbols which names are thought as C/C++ symbols, prefer shortest one
*Support for symbol files + Hatari profile data containing demangled C++ symbols
*Support weak symbols (used for C++ template methods)
*Overtly long C++ symbol names are shortened in callgraphs (unless '--full-symbols' option is given)
*Symbols given for "--only", "--ignore" and "--ignore-from" are interpreted as match patterns (with '*?[]' wildcards)
*Only single arrow shown between callgraph nodes when "--compact" option is used
- m68k-instructions: (new)
*Tool for printing m68k instruction breakpoints & opcode info
Build improvements:
- Fix: CPU core compile warnings (WinUAE upstream)
- Fix: groff/troff warnings for manual pages
- Use cmake config file provided by the SDL2 library instead of trying
to detect the SDL2 library ourselves (fixes compilation on macOS)
- Removed unused sources for HD6301 emulation
- Hatari can now be compiled with emscripten, too
Fixed demos:
- Chaos A.D. : bad sound (Falcon DMA sound interrupts)
- Little -ME- Demo end part by Overlanders : black screen after a while (IACK timing)
- Monscape : bad sound (TT/DMA FIFO update)
- Time Slice by Defence Force : monochrome demo (crash when Hatari
is compiled with "small mem" option)
- What If by Troed/Sync : 4 pixel hardscroll on STF by stopping shifter
- Oergs, Terrorize your soul, Zero Three Zero demos work now also
when MMU is enabled
Fixed programs:
- FlaySID (DSP host handling)
- AFM sound with equalizer enabled (DSP modulo)
- FreeMiNT (use SCC counter at start to detect the SCC clock freq)
- Spectre 3.0 Macintosh emulator (stacked PC in case of bus error)
- m68k-Linux works (again) with 040/060 emulation (MMU)
- m68k-NetBSD does not crash on boot any more (MMU)
Fixed games:
- F29 Retaliator using CTR/IPF format (handle FDC's TR reset bug in caps library)
- MIDI (MFP IRQ clear) handling:
*Bad Mood
*Midi Maze
*Midi Maze II
*Oxyd 2
- Work now also when MMU is enabled:
*Gravon (demo)
*Killing Impact
*Moongame |
