Cet émulateur multi-systèmes a été mis à jour. Les améliorations sont les suivantes:
- SNES: Updated libco to latest.
- Paths included in informational and error messages are now outputted with ASCII control characters non-reversibly transformed by inverting bit 6 and prefixing with a "^" character.
- When loading a game from a ZIP archive, the path used within the ZIP archive is now outputted in an informational message.
- The paths of CD images specified within M3U files are now outputted in informational messages as they are loaded.
- Added support for loading CD images from ZIP archives when the "cd.image_memcache" setting is set to "1".
- Implemented an M3U recursion limit of 9, adjustable by the new setting "cd.m3u.recursion_limit".
- Implemented a limit of 25 on the total number of CD images loaded while processing M3U files, adjustable via the new setting "cd.m3u.disc_limit".
- Implemented a size sanity limit of 65535 bytes for PSF tag source data.
- Changed handling of single gzip/Zstd compressed files to treat the .gz/.zst suffix as the second part of the extension, instead of the whole extension, with respect to Mednafen data file path construction and naming.
- Added undocumented setting "filesys.old_gz_naming", that can be set to "1" by the user to restore the old data file naming behavior for gzip-compressed files for backwards-compatibility reasons.
- Added Zstandard decompression support to game loading, with both naked files("zst" extension) and ZIP archives.
- SS: Don't send CD data sectors to partition buffers when the disc hasn't gone through the authentication process.
- SS: Moved some CDB CD reading variable initialization into StartSeek() to reduce the amount of redundant error-prone code.
- SS: Don't erroneously signal CDB EHST HIRQ when ending a TOC or file info data transfer.
- SS: Implemented more aspects of the CD block disc authentication process. Fixes abort to CD player screen when trying to start a game demo in Gremlin Interactive's "Demo Disc".
- SS: fixed a few issues with CD block directory reading and handling of directories with more than 256 entries.
- SS: Added commented-out partial fix for end-of-level hang in "Loaded".
- SS: Changed midsync event time initializing to use SS_SetEventNT() instead of doing it directly(and breaking when the midsync event isn't the last enumerated event)
- SS: Added a dev build event order sanity check to ForceEventUpdates().
- SS: Implemented a delay when the SMPC joystick read process is aborted due to time over or due to the Break bit being 1, per tests on a SS, and fixed timing granularity issues with the processing of the Break/Continue bits; fixes unresponsive input in "Discworld", and abort to CD player screen in the USA and Europe releases of "Primal Rage".
- SS: Added "Senkutsu Katsuryu Taisen: Chaos Seed" to the internal database of games to enable full cache emulation with, to fix the inability to skip the intro FMV.
- An empty string for a setting that expects a numeric value is now rejected instead of being treated as 0.
- Misformatted setting file lines are now rejected with an error instead of silently ignored.
- SS: Fixed a mistake in an invocation of the SH-2 emulation Branch() macro that caused an expensive debugger function to be called even when the debugger was not active, hurting performance.
- Settings file parsing error messages now include line numbers when relevant.
- SS: Removed MDFN_COLD from SH7095::SetDebugMode(), as it causes newer gcc's optimizer to make bad assumptions and place the main CPU execution loop in the cold text section.
- Providing an empty string for a setting that expects an integer or real number will now result in an error, instead of being treated as 0.
- Modified the settings code to use the new string<->integer conversion functions, for stricter parsing(nonsense like "0x -0x1" is no longer allowed) and better error messages in certain cases.
- Added new string<->integer utility conversion functions.
- SS: Implemented a simple optimization in the VDP1 drawing code, reducing executable size by about 900KB on x86_64 Linux.
- Added MDFNI_SaveSettingsCompact(), to be used in the future for settings backups.
- Added tests for clamp_to_u8(), clamp_to_u16(), and MDFN_abs64().
- Added the MDFN_abs64() function.
- Rewrote the sign_*_to_s*() macros and clamp_to_u8/u16() functions.
- Added MemoryStream::get_line_mem() function to allow for more efficient parsing of large line-delimited text files.
- Added MDFN_memdupstr() function, stuck the guts of the settings handling code in a class, and reworked the settings file loading code to be a bit faster.
- Added inline FileStream::put_char() function, and optimized the settings file saving code.
- Reworked how setting generation at startup works a bit to reduce the number of memory allocations, and added setting flags to mark strings that should be free()'d when MDFNI_Kill()->MDFN_KillSettings() is called at exit, to reduce noise when checking for memory leaks.
- Fixed currently-benign memory leak in the FPS display code.
- SexyAL: Fixed memory leak in dummy sound driver.
- SexyAL: Modified the ALSA driver code to not use a VLA for the noninterleaved multichannel support.
- Fixed an instance of undefined behavior in SwiftResampler.
- Added a couple more compiler bug/sanity tests.
- Rewrote some of the small inline utility functions in CDUtility.h, and added tests for the rewritten utility functions to ensure correctness and stable semantics.
- Added test for gcc bug #97760.
- Added crc32_cdrom_edc() function(to be used later), reimplemented crc16_ccitt() with the new generic fast CRC calculation template function, and added a few CRC calculation sanity tests run at startup.
- SS: Fixed an off-by-150 bug in the CDB code, present since the first release with Saturn emulation, that caused the read hinting at the start of emulated seeks to not have the desired effect.
- SS: Implemented emulation of the CDB Scan command.
- SS: Optimized the SCSP sound CPU interrupt level calculation code.
- SS: Fixed a few inaccuracies in the relative timing of SCSP timer increments across different prescaler rates, per tests on a SS.
- SS: Added emulation of the SCSP MIDI interface output logic and approximate timing.
- SS: Fixed a few inaccuracies in the relative timing of SCSP EG level updates across different rates, per tests on a SS.
- Typedef signed char and unsigned char to int8 and uint8 respectively, instead of relying on int8_t and uint8_t, in case they're ever implemented without the aliasing properties of char types, which Mednafen code relies on.
- SS: When a CDB seek is started very shortly after another seek, don't elide the previous seek's startup side effects; fixes the CD audio player in the North America/Europe BIOS, which broke with 1.26.0-UNSTABLE.
- Compile with -Wstack-usage=32768 to check for excessive stack usage in functions.
- VB: Added "left" and "right" options to the "vb.3dmode" setting, to allow for more easily showing only the left or right view.
- Added setting "video.cursorvis", to control the window manager default cursor visibility.
- Use AtomicFIFO for the main thread->emulation thread event queue, and fixed related excessive(100+ KB) stack usage in a couple functions.
- SS: Added "Saturn Super Vol. 2" to the internal database of games to use the data cache read bypass kludge with, to fix the flickering title screen in the "Golden Axe: The Duel" demo.
- SS: The VA0/VA1 motherboard's memory mapping behavior for Low-RAM is now emulated instead of VA2's, to fix a crash in "Myst" in the generator room.
- SS: The emulated reset button mapped to Mednafen's reset command key(F10 default) will now respect the "ckdelay" setting.
- Added a quick configure script test to check if disabling PIC/PIE breaks the compiler/linker, and if it does, PIC/PIE is not disabled, to prevent a link-time failure on Haiku.
- Use AC_TRY_LINK() instead of AC_TRY_COMPILE() in the configure script test for AVX inline assembly availability, to handle toolchain setups where the assembler is run at link time instead of compile time.
- Added setting "video.force_bbclear", default value of "0", which when set to "1" will force clearing of the backbuffer before drawing every frame. |
