Une nouvelle version, instable pour le moment, de cet émualteur multi-systèmes a été publiée. Les améliorations sont les suivantes:
- SS: Corrected threshold and semantics of envelope level-based blocking of slots' access to SCSP RAM, per tests on a SS.
- SS: Fixed a big-endian target incompatibility in the SCSP emulation code.
- Use ternary operator instead of std::min in endian.h, as doing so somehow causes gcc to produce smaller and faster machine code.
- PSX: Removed incorrect filtering of CD-XA ADPCM sectors based on the file and channel numbers of the first ADPCM sector played,- originally added in 0.9.24-WIP to fix the speech playback in "Yarudora Series Vol.1: Double Cast", but made unnecessary by later sector buffering accuracy improvements; fixes missing audio in the FMVs of "Blue's Clues: Blue's Big Musical".
- PSX: Adjusted which sectors are processed and reflected by GetLocP after SeekP completes to only those before the seek target(which is slightly different than SeekL behavior, which also includes the target and a few after, at least with a typical PS1 CD); fixes hangs at different points in some versions of "Tomb Raider", a problem initially fixed in 0.9.38.3, but regressed in 1.22.0-UNSTABLE.
- VB: Block writes to VSU registers and memories when A0 and A1 are not both 0, per tip from "enthusi".
- SS: Implemented incomplete(regarding stack frame data) M68K address error handling, and implemented M68K halting when accessing addresses where any of A21-A23 is 1. Fixes major audio distortion during boss battles in "Lunar: Silver Star Story" due to SCSP DSP register corruption that occurred when the game crashed the sound CPU during bootup.
- SNES-Faust: Don't call event handlers in read/write handlers if the read/write is from DMA/HDMA, to avoid problematic recursion and related issues.
- SNES-Faust: Fixed clearing of pending SuperFX IRQ on reset/power; fixes hang/crash in "Stunt Race FX" upon performing a virtual power toggle after the game boots up.
- SNES-Faust: Added commented-out fix for "Speedy Gonzales", to enable later.
- SNES-Faust: Added detection heuristics and support for mapping LoROM RAM into $8000-$FFFF, to fix save game saving/loading in "Light Fantasy", "PGA Tour Golf", and "Ys III".
- SNES-Faust: Added commented-out fix for "Kishin Douji Zenki Tenchi Meidou", to enable on a per-game basis in the future due to a minor negative performance impact.
- SNES-Faust: Reworked cart header detection and cart type detection logic a bit, fixes "Yuuyu no Quiz de Go! Go!".
- SNES-Faust: Return open bus in bits 4 through 6 for reads from $4210; fixes early hang in "Super Professional Baseball II".
- SNES-Faust: Return open bus in bits 0 through 6 for reads from $4211; fixes early hang in "Yuujin Janjuu Gakuen 2".
- SNES-Faust: Added support for special ROM mapping required by "Derby Stallion 96" and "Sound Novel Tsukuru".
- SNES-Faust: Changed power-on APU RAM initialization pattern; fixes hangs in "Ihatov Monogatari" and "Kyuuyaku Megami Tensei".
- Fixed an off-by-1 error in the multithreaded CD reader that would cause a hang if a read was attempted for the sector at LBA 449849.
- Fixed a design flaw that caused the creation of empty backup counter files when automatically attempting to back up a nonvolatile memory save file that does not exist.
- SNES-Faust: Disabled the PPU brightness modulation sanity check when compiling a non-dev build, and fixed array misalignment that was causing the code to segfault when compiled with stack smashing protection enabled on newer gcc.
- Resync console scroll to the last drawn line of the target unwrapped line in the scrollback buffer, not the first, otherwise the console will erroneously scroll up on windowed<->fullscreen transitions when the last line is wider than the console viewport, confusing the user. Fixed rendering of Unicode combining characters, fixed handling of combining characters when entering text in the console and debugger prompt, added support for pasting into the debugger prompt, cleaned up rendering of the debugger prompt box, implemented automatic scrolling when entering text in the debugger prompt, made console text entry automatic scrolling bidirectional, changed console scrollback buffer beginning/end scroll key combos to CTRL+Home/CTRL+End instead of SHIFT+Home and SHIFT+End, added support for clearing multiple characters at once in the console and debugger prompts by pressing CTRL with Backspace/Delete.
- Added support for reinitializing game controllers while Mednafen is running by pressing Shift+F3.
- Aborting the input configuration process for a virtual device will now discard the new configuration data, instead of combining it with the old configuration data for the not-configured buttons as previously done.
- Added "upper_center" and "center" options to the "fps.position" setting.
- WonderSwan: Fixed RTC month field being incorrectly treated as 0-based instead of 1-based.
- Give the user feedback when they try to toggle a graphics layer that doesn't exist or isn't toggleable.
- NGP: Sanitize some sound-related variables on state load to prevent potential memory corruption.
- SMS: Sanitize more variables on state load.
- NES: Fixed a few instances of missing variable initialization on poweron.
- GB: Sanitize a few variables on state load.
- Automatically create any missing parent directories to the Mednafen base directory on startup.
- Create each Mednafen data directory(e.g. firmware, sav, snaps, etc.) at startup based on the current value of the filesys.path_* setting instead of based on its default value, unless the corresponding filesys.fname_* setting is not set to its default value, in which case the directory is not created.
- NES: Sanitize more sound emulation variables on state load.
- NES: Added missing VRC6 variables to save states.
- GBA: Backup save game memory files on game load
- SMS: Fixed a bug that could cause the emulated reset button state to get stuck as pressed if a hard reset occurred within about 20 frames after a soft reset.
- GBA: Added a few missing variables to save states.
- GB: Added a few missing variables to save states.
- PCE-Fast: Renamed encapsulating namespace from "PCE_Fast" to "MDFN_IEN_PCE_FAST", to match the convention of all other emulation modules.
- Made Emulated* MDFNGI objects constant, copied over to a dynamically-allocated MDFNGI assigned to MDFNGameInfo on game load.
- Dynamically-allocate QTRecord LZO work memory.
- Apple2: Dynamically allocate state helper floppy disk object.
- PCE-Fast: Fixed massive overallocation of memory for the VDC background tile cache.
- Optimized MDFN_FastArraySet() for non-ideal counts.
- Utilized MDFN_HIDE in more places.
- Removed incomplete YCbCr MDFN_Surface support unused since 0.9.x, and likely to remain unused.
- Added support for 16bpp graphics output to core Mednafen code and the majority of emulation modules(excluding "pce", "pcfx", "psx", "snes", "ss", and "vb"), and added setting "video.glformat" to allow for using this support with OpenGL.
- PSX: Initialize some missed state on reset/poweron.
- Completely rewrote the save state preview image resizing code, so that now it's only somewhat wrong, instead of mostly wrong as before.
- GB: Use fastcall on 32-bit x86, for a tiny performance boost.
- Use MDFN_RESTRICT macro instead of __restrict__.
- NGP: Use fastcall calling convention on 32-bit x86 to boost performance a little bit.
- Apple2: Disabled some expensive asserts when compiling without MDFN_ENABLE_DEV_BUILD defined.
- Birthed pernicious human date/time calculation functions to replace the usage of _gmtime64() and _localtime64() on Windows, for Windows 9x compatibility.
- Set icon using Win32 API functions on Windows instead of relying on SDL_SetWindowIcon(), and use alternate, smaller(and boxier!) window icons when running on Windows 9x so the poor beetle doesn't look splatted.
- Don't call SetConsoleOutputCP() on startup on Windows, as it messes up the cmd.exe console on Windows 7(at least) even when Mednafen has exited, and for Windows 9x compatibility.
- Pass a pointer to a dummy variable, instead of NULL, as the output thread identifier pointer argument to _beginthreadex(), for Windows 9x compatibility.
- Allow for the absence of GetConsoleWindow() on Windows, for Windows 9x compatibility.
- Automatically attempt to lock file offset 0xFFFFFFFF if the attempt to lock offset 0xFFFFFFFFFFFFFFFF fails with an invalid parameter error on Windows, for Windows 9x compatibility.
- Use SetFilePointer(), GetFileSize(), and LockFile() instead of SetFilePointerEx(), GetFileSizeEx(), and LockFileEx() on Windows, for Windows 9x compatibility.
- Dropped usage of and dependency on libsndfile, and added a direct dependency on libFLAC. The only CD image audio file formats/encodings other than raw supported now are: FLAC, Ogg Vorbis, Musepack, and uncompressed PCM in AIFF/AIFC, AU/SND, W64, and WAV.
- Require the first four bytes of the tentative Ogg Vorbis file to be "OggS" before calling ov_open_callbacks(), to prevent unnecessary excessive reads when trying to determine the type of the audio file, and to avoid treating a non-Vorbis file as Vorbis under certain conditions.
- Open the main settings file for both reading+writing on startup instead of just reading, to allow file locking to work over NFS, and as a quick check to make sure the file is writeable before it's too late upon exit.
- Made various changes to the Windows support code, to allow for compiling a non-Unicode Windows build.
- Implemented stream buffering in the FileStream class, now using read(), write(), etc. instead of fread(), fwrite(), etc. |
