Émulation en folie : les derniers émulateurs à tester sur Mac et iOS

Version 2.5.0 (2024-04-18)
 --------------------------
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)+,<regs> 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 <x>" (<x> = png or bmp or neo or ximg)
- Memory Snapshot:
  - Add some missing variables to the savestate

  - "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

  - 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)
  - "<name>.sym" file beside program file acts as its symbols override
  - Add optional argument for "symbols <name|code|data>" 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)

Apr 10

• Disable harfbuzz (Do Trong Thu)

Version 4.6.00, Build 6414

• Bug fixes
  • When starting the simulator, the simulator window could be outside of the visible area when the monitor layout had changed after saving the window position.
  • Program description dialogue: When the Search and Replace window was closed, the input focus was not set to the edit window.
  • The mnemonics in the program popup menu did not respect the current setting for the comma and the thousands separator.
• Changes
  • Key sequences with a decimal point, e.g. STO . 3, are now formatted as { 45 .3 } or { 45 ,3 } in the program files. The actual format depends on the settings for comma and period. In previous versions the sequence was formatted using the key code ('48') for the decimal point, e.g. { 45 48 3 }.
  • The entire simulator documentation was checked using DeepL Write. The use of nouns, such as button vs. key, and verbs , such as show vs. display, is now more consistent.
  • Program description dialogue:
    • The statistics registers R2 to R7 are now automatically added to the program description, when the program uses the commands Σ+ or Σ-.
    • Selected text in the Usage field now remains highlighted, when the field looses the focus. For example when you open the Search and Replace window.
    • The preview mode now supports text that is formatted in bold and italic at the same time.
    • The symbols menu can be opened at the cursor position with the shortcut Control–B3 (not for macOS).
• Known issues
  • macOS
    • When minimising the description dialogue, it becomes immediately maximised again
    • Artifacts along the top and bottom edge of the simulator keys for some font sets
    • Some users got errors when they installed the HP-15C Simulator Font. It is recommended to deinstall all versions of the font before installing it again.
  • Linux, macOS:
    • The behaviour described on page 144 of the Owner's Handbook when a letter key is 'held down for longer than about 3 seconds', works on all systems when you use the mouse. When you use the keyboard, it works on Windows, but not on macOS and Linux.

v2024.4.22

• new NewtonScript function for Toolkit: MakeIconFromFile("something/something.png") generates a black and white icon frame using the gray or red channel of an image and the alpha channel, if it exists
• fixed newt/64 package generation where it was generating superfluous _nextArgFrame entries.

1.8.1

• UI: implement an option to pause the emulator when the window is inactive
• UI: improve lack of response to input changes in the sprite viewer when the emulator is paused
• UI: replace QOpenGLWidget with QWidget (thanks @GranMinigun)
• UI: fix solar sensor level menu that has been broken in 1.8.0 (fixes #370)
• GPIO: fix broken deserialization of port directions
• APU: MP2K HLE: handle corrupted wave info addresses (fixes #362)
• APU: PSG L/R volume must be remapped from 0-7 to 1-8
• GameDB: Japanese Boktai releases have a solar sensor (thanks @raphaelr)
• Redirect stdout on Windows (thanks @GranMinigun)

0.2.2

Compatibility:

• New working apps:
  • Rayman 2 (@ciciplusplus)
  • Tony Hawk's Pro Skater 2 (@ciciplusplus)
  • Earthworm Jim (@ciciplusplus)
  • Castle of Magic (@ciciplusplus)
• API support improvements:
  • Various small contributions. (@alborrajo, @WhatAmISupposedToPutHere, @ciciplusplus, @hikari-no-yume, @LennyKappa, @Skryptonyte, @teromene)
  • AAC audio files (AAC-LC in a typical MPEG-4 container) are now supported in Audio Toolbox. This is done in a fairly hacky way so it might not work for some apps. (@hikari-no-yume)
• There is now support for iPhone OS 3.0 apps, in addition to the existing support for iPhone OS 2.x apps:
  • Support for fat binaries has been added. touchHLE will no longer crash when trying to run an app with both ARMv6 and ARMv7 versions, and instead will try to pick the best available option (ARMv7, or failing this, ARMv6). This improves compatibility with iPhone OS 3.0 apps, many of which use fat binaries in order to improve performance on the iPhone 3GS and iPod touch (3rd generation). (@WhatAmISupposedToPutHere)
  • The bundled ARMv6 dynamic libraries, libgcc and libstdc++, have been updated to their iPhone OS 3.0.1 versions. Previously the iPhone OS 2.2.1 versions were used. (@hikari-no-yume)
  • touchHLE will no longer output a warning when trying to run an app with iPhone OS 3.0 as its minimum OS version. The warning now only appears for apps requiring iPhone OS 3.1 and later. (@hikari-no-yume)

Usability:

• The --button-to-touch= option now supports the Start and the LeftShoulder buttons in addition to the A/B/X/Y buttons and D-pad. Certain games' default options have been adjusted to use them. (@nighto)
• Default options for various games (@nighto)

	PSX: Added support for Konami's "Pop'n Music" controller.
December 22, 2023:
	Added setting "input.grab.strategy" to control when the system keyboard and mouse are grabbed while input grabbing is
	toggled on in Mednafen.  Note that SDL2 2.0.16 or later is required for the non-default "auto" option to fully work.
December 18, 2023:
	Fixed excessive CPU usage when sound is disabled or fast-forwarding is active while in frame advance/pause or in the
	cheat interface.
December 17, 2023:
	No longer set environment variable "__GL_SYNC_TO_VBLANK", instead relying only on SDL_GL_SetSwapInterval(),
	as it seems to work fine nowadays with Nvidia's binary Linux driver, to avoid thread safety issues with
	environment modifications.
	Renamed configuration macro "PSS_STYLE" to "MDFN_PSS_STYLE", and path-separator string macro from "PSS" to "MDFN_PSS".
December 15, 2023:
	PSX: Renamed setting "psx.dbg_level" to "psx.dbg_mask", and changed its type to a multi-enum, to allow for more granular
	enabling of debug messages.

	a MDFNST_MULTI_ENUM-type setting.
	PSX: Snoop additional BIOS tty stdout functions when setting "psx.dbg_level" is 2 or higher.
December 2, 2023:
	Patched SDL2 in the Windows build toolchain to ignore synthetic Left CTRL key events generated by AltGr,
	when keyboard input grabbing is active.
	Demo: Added an interactive graphical keyboard test mode to check input grabbing and SDL2 keyboard support,
	among other things, activated by changing the value of new setting "demo.mode" to "keyboard".
November 29, 2023:
	PCE, NES: Fixed broken rendering in the graphics debugger when the OSD pixel format is not the same as the emulation
	video pixel format.
November 28, 2023:
	Changed the OpenGL RGB555 support(e.g. via the "video.glformat" setting) to use a pixel format and type of
	GL_RGBA and GL_UNSIGNED_SHORT_5_5_5_1(instead of GL_BGRA and GL_UNSIGNED_SHORT_1_5_5_5_REV as before).
	Set emulation video texture parameters GL_TEXTURE_WRAP_* to GL_CLAMP before trying to set them to GL_CLAMP_TO_BORDER,
	to avoid texture wrapping on pre-1.2 OpenGL.
November 26, 2023:
	Added support for 16bpp video/framebuffer modes, dependent on specific emulation module support, when OpenGL is
	disabled.
	Blocked the graphics debugger from being selected when it's not implemented for the current emulation module.
	Fixed hang when a post-startup error occurred during video reinitialization or blitting, due to erroneously unlocking
	a mutex twice.
November 23, 2023:
	Updated toolchain for official Windows builds(non-Win9x):
		binutils 2.28 -> 2.28.1
		flac 1.3.2 -> 1.3.4
		mingw-w64 5.0.3 -> 5.0.5
		SDL2 2.0.8-11835 -> 2.28.5
		zlib 1.2.8 -> 1.2.13
	Additionally, the 32-bit build of SDL2 has been patched to restore support for Windows 2000, broken since the migration
	to SDL2 in Mednafen 1.x.
November 21, 2023:
	Apple2: Delay Disk II processing of normal flux pulses vs. random noise pulses, and disable the 500ns delay
	pseudorandomly(50% probability) added to normal pulse detection, as it breaks WOZ dumps of "Test Drive" and "Wizardry".
November 19, 2023:
	Fixed design flaw in MDFN_strargssplit() that broke handling of an escaped backslash immediately preceding a closing
	double quote character.
November 18, 2023:
	Documentation: Added support for hyperlinks to settings in the description text for settings, custom palettes, and
	internal databases, by enclosing the setting name in double quotes and prefixing the name with ASCII control
	character 5.
	Fixed broken handling of octal along with a few edge case issues in MDFN_strunescape().
	In MDFN_strescape(), escape control characters in 3-digit octal instead of 2-digit hex or 1-digit octal to avoid
	potential conflicts with subsequent characters.
October 21, 2023:
	Align QTRecord CSCD video codec line data to 4-byte boundaries, as is correct, to fix broken recorded video in some
	circumstances.

	32MiB or smaller, and force full cache emulation to be enabled when running with a bootable ROM cart image.
	SS: When loading a save state, mark internal and cart backup memories as dirty only if loading the state actually
	changed them, to try to avoid excessive disk writes when using state rewinding.
	SS: Added support for routing SCSP MIDI output to stdout, activated by changing the value of the new "ss.midi" setting to
	"stdout". Note that byte values of 0x1B will be filtered from the output, and timing synchronization issues limit
	its uses outside debug text output. 
October 12, 2023:
	SS: Corrected behavior of VDP2 color calculation blending when in both hires mode and a non-zero color RAM mode.
October 11, 2023:

	for around 49.7 days
	Changed the default mapping for exit to just F12 instead of ESC and/or F12.
	Added a new hotkey for closing the netplay popup, by default mapped to "ESC", controlled by setting "command.close_popup".
September 10, 2023:
	Apple2: Added "rgb_qd" and "rgb_qd_tfr" video rendering modes, which will render DHGR at quarter-resolution, and provide
	two distinct grays in all graphics modes.
September 9, 2023:
	Apple2: Renamed keyboard input mapping settings to reduce their lengths, and documented the caps lock default position setting.
	Apple2: Changed how HGR is handled with the "rgb_alt" and "rgb_alt_tfr" video rendering modes, for consistency with DHGR

	more-specific per-module and per-game override configuration files.
April 4, 2023:
	Apple2: Added high-level(no seek delay) ProDOS-compatible hard disk drive emulation, usable by loading a raw hard
	disk drive image with an "hdv" file extension, and through the "hdd" directive in a MAI file.
March 28, 2023:
	Apple2: Added support for Apple IIe and Enhanced IIe, selectable via changing the new "apple2.model" setting, or
	by utilizing the new "model" directive in a MAI file.
	Apple2: When loading a floppy disk image from a ZIP archive without a MAI file, all other floppy disk images with the same
	extension in the same directory in the ZIP archive will now also be loaded automatically. If desired, this feature can be
	disabled by setting the new "apple2.multiload" setting to "0".
March 26, 2023:

	SNES: Fixed #if/#ifdef typo in libco PPC code that reportedly broke libco on PPC when compiling with clang.
July 16, 2022:
	MD: Fixed bad values in the PAL V28 VCounter table(though normal resolution interlace VCounter stuff still needs to be fixed).  Fixes glitches and
	hang in the Europe release of "Donald in Maui Mallard".
	Fixed some M68K instruction and exception execution time inaccuracies.
	Implemented emulation of M68K instruction Scc's dummy read.
July 4, 2022:
	SS: Added basic ST-V support.
	SS: In SMPC INTBACK command processing, when starting controller reading after returning SMPC status, wait for Continue/Break *before* waiting for the end
	of VBlank, prioritize Continue over Break, and don't allow the wait for end of VBlank to be interrupted by setting the Break bit, per tests on a SS.
June 30, 2022:
	Extended support for configuring buttons on virtual ports from port 12 to port 13, using new key combo ALT+SHIFT+Keypad 3, and switching devices
	by CTRL+SHIFT+Keypad 3, for future use.
June 25, 2022:
	Added std::string variants of MDFN_strazicmp().
	Adjusted minimum file extension search priority(e.g. for ".bin" and ".exe" extensions) from -80 to -1000.
June 20, 2022:
	Added initial value argument to crc16_ccitt().
June 14, 2022:
	Added support for returning CRC32 values in VirtualFS::finfo(), for entries in a ZIP archive.
June 12, 2022:
	SS: Trigger mid-frame synchronization when going into vblank if not already triggered by SMPC INTBACK command processing.
March 26, 2022:
	SS: When VDP2 per-dot RBG0 coefficient reading is enabled, and a per-dot coefficient read is attempted from a memory region not configured for that purpose
	via RDBS, force the coefficient data to 0, instead of using the per-line coefficient data.  Fixes graphical glitches in "Radiant Silvergun" when starting
	a new game after interrupting the attract mode during the AKA-O battle.
March 23, 2022:
	SS: Forcibly disable NBG1-3 only if both RBG0 and RBG1 are enabled via BGON, instead of only checking if RBG1 is enabled; fixes missing/glitchy graphics
	in "Houkago Ren'ai Club: Koi no Etude".
March 9, 2022:
	SNES-Faust: Fixed broken ExLoROM support.
	PCE, PCE-Fast, PC-FX:  Update channel 1 frequency cache upon LFO frequency register writes(the way the channel 1 frequency and LFO frequency are combined
	is still inaccurate, however, causing frequency update timing granularity to be too high).
February 4, 2022:
	SNES-Faust: Fixed PPU window emulation bug that caused graphical glitches with a white circle at a few places in "Final Fantasy 5".
February 2, 2022:
	PC-FX: Expanded external backup memory to 128KiB, and changed it so that internal backup memory and external backup memory are saved to/loaded from separate files.
January 22, 2022:
	SASPlay: Added support for "Air Walkers".
-- 1.29.0: --
January 12, 2022:
	PCE, PCE-Fast: Initialize VCE color table memory at power-on to roughly(without probabilistic bit randomness) match test results from a
	PC Engine Duo instead of just zeroing it; fixes unreadable letters in the password entry screen of "Order of the Griffon".
	Added test for potential splatting-related bug in qemu's PPC64 VSX "xscvdpsp" instruction emulation that messes up OwlResampler when compiled with gcc.
January 11, 2022:
	PCE: Added patch in the "notes" subdir for extending the upper range of the "pce.slend" setting to 241(not applied in Mednafen due to increasing
	the probability of an extra 8ms of input lag with some games).
January 9, 2022:
	VB: Fixed a couple inaccuracies in the VSU modulation emulation, fixing a few sound effects in "Virtual Boy Wario Land".
January 7, 2022:
	SNES-Faust: Fixed S-DSP pitch modulation being half as strong as it should be.
December 29, 2021:
	SNES: Fixed wrong compile-time endian detection on little-endian PPC64.
December 24, 2021:
	PCE: Fixed incomplete initialization of the VDC BG tile cache; fixes glitches after the boss explodes in "R-Type" under certain
	conditions(more likely to occur in forks of Mednafen).
December 20, 2021:
	NES: Added missing mapper 90 variables to save states.
December 5, 2021:
	Placing a "%d" or "%b" specifier at the beginning of a filesys.fname_* setting format string will now cause the generated path to be used as-is, rather
	than potentially being prefixed with the corresponding filesys.path_* setting or the Mednafen base directory.  Fixes a regression introduced in
	1.28.0-UNSTABLE that caused IPS patch files to be loaded from the wrong location when the user had loaded a game via a relative path.
November 29, 2021:
	Added support for playing the SCSP-generated music from most Sega Model 2A, 2B, 2C, and 3 games, via the new experimental "sasplay" module.
November 15, 2021:
	SNES: Fixed compilation error for little-endian PPC64 with LTO enabled.
	Fixed compilation error after running configure with --disable-fancy-scalers.
