Mednafen v1.22.0 Changelog:
December 11, 2018:
SS: Added support for directly loading <= 1MiB bootable cart ROM images, with the expected file extension being "ss", for debugging and testing purposes. December 2, 2018: SS: Added "Fighting Vipers" to the internal database of games to use the data cache read bypass kludge with, to fix the problem of the computer-controlled opponent sometimes losing the will to not be a statue. December 1, 2018: PSX: Memory cards are now backed up on startup(maximum number of backup copies kept for each memory card is 5). November 30, 2018: PCE: Increased CD read startup delay per tip from dshadoff. Fixes ADPCM voice playback issues in "Downtown Nekketsu Monogatari" when text speed is set to fast. MD: Fixed a few errors in the internal automatic multitap database, per tip from clobber. SS: Added setting "ss.cart.auto_default". NES: Removed apparently erroneous iNES header correction database entry for "Dragon Quest II" that was breaking the game. November 6, 2018: VB: Added the ability to toggle the state of the low battery sensor bit; configure the device on virtual input port 2(e.g. ALT+SHIFT+2) to assign a key/button to this function. November 4, 2018: PSX: Added a pseudorandom component to Pause command timing to address loading-related hangs in "Colony Wars - Vengeance (Europe)" and "Army Men - Air Attack (Europe)". PSX: Generate a seek error if the tray is opened while the CD drive is not stopped; fixes broken disc switching in "Arc the Lad III". November 3, 2018: PSX: Improved emulation of the behavior of CDC command 0x0A per tests on a PS1; fixes hang in "Goryuujin Electro". November 2, 2018: PSX: Don't set the autopause track test value unless autopause is enabled; fixes missing music in "Pitball". PSX: Delay first CD-DA report after playback begins, per tests on a PS1; fixes missing music in "Roswell Conspiracies - Aliens, Myths & Legends". October 31, 2018: PSX: Improved timing of CDC command 0x0A per tests on a PS1; fixes missing music and hangs in "Grind Session". PSX: Altered seek and pause timing and behavior per tests on a PS1; fixes hangs in "Incredible Crisis", "Ballerburg - Castle Chaos", "Transformers - Beast Wars Transmetals", and "Simple 1500 Series Vol. 057 - The Maze". October 28, 2018: The settings management code will now throw an exception if a floating-point setting is NaN. Fixed a crash that occurred when "debugger.autostepmode" was set to "1" and a game was loaded for a system for which debugger functionality was not implemented. NativeVFS, FileStream, and GZFileStream methods taking a path will now throw an error when the path contains a null character. October 23, 2018: SNES-Faust: Added recognition of files with "fig" and "swc" file extensions as SNES ROM images. October 9, 2018: Altered the variants of MDFN_rtrim(), MDFN_ltrim(), MDFN_trim(), MDFN_zapctrlchars(), MDFN_strazlower(), MDFN_strazupper(), and UTF8_sanitize() that operate on a mutable std::string to take a pointer to the std::string instead of a non-const reference, and added variants that take a const std::string reference and return a std::string result. October 8, 2018: Dropped support for "game set" hashes used to change the naming of save state and save game files. The feature was mostly broken by changes made years ago, and is redundant now with M3U support. Save game files for multi-disc PC-FX games created in previous versions of Mednafen will need to be renamed to be seen by this and newer versions of Mednafen. Other files, including save states, should generally be unaffected, unless the user has changed filesys.fname_* settings to use the %F specifier where they wouldn't by default. Removed usage of the deprecated "register" keyword in some old code. October 7, 2018: Adjusted placement of MDFN_FASTCALL and NO_INLINE to fix some compilation errors with MSVC. In addition to nonvolatile memory backup files as before, any missing directories in the file path for input-recording movies, save states, screen snapshots, and nonvolatile memory files are now created as necessary, to increase the versatility of the filesys.fname_* settings. October 6, 2018: Implemented partial virtual filesystem support via classes VirtualFS, NativeVFS, and ZIPReader. Emulation modules' loading of files referenced from the main file being loaded is now done through its associated VFS. This does create a small backwards-compatibility issue with PSF-family(PSF, SSF, GSF, etc.) files, in that previously a ZIP'd PSF-family file that referenced a library file would have the referenced file loaded from the directory containing the ZIP file, but now will have it loaded from within the same ZIP file. October 4, 2018: NGP: Replaced min/max macros with usage of std::min/std::max. September 30, 2018: Modified usage of std::swap in OwlResampler.cpp to not explicitly(and unnecessarily) specify the template argument, to fix a compilation error on MSVC. Reworked FileStream.cpp to fix some issues causing errors on MSVC. GBA: Fixed a regression introduced in 0.9.47 that partially broke compatibility with save states created in previous versions(< 0.9.47), while preserving compatibility for save states created in versions between and including 0.9.47 and 1.21.3. September 29, 2018: SNES-Faust: Added RAM cheat support(main WRAM only for now). SNES-Faust: Added emulation of PPU-area open bus/bus read latches; fixes missing sprites in the water stage of "Mario's Time Machine". SNES-Faust: Corrected H/V latch reading to use two separate high/low byte toggles. September 24, 2018: SNES-Faust: Made minor changes to the CPU emulation core to not require computed goto support in the compiler. September 23, 2018: Added "blend" and "blend_rg" deinterlacers. Moved multithreading management code into the core. Encapsulated most(ish) core Mednafen code in the "Mednafen" namespace. Slightly improved the quality of audio output by SwiftResampler when running at the higher quality settings. September 22, 2018: Moved NES audio resampler so it can be used by any emulation module, and renamed it to "SwiftResampler". Added an SSE intrinsics-utilizing MAC loop to OwlResampler as a fallback(for the inline assembly) when compiling with MSVC. Added an SSE2 intrinsics-utilizing MAC loop to SwiftResampler as a fallback(for the inline assembly) when compiling with MSVC. September 21, 2018: Wrote new Kaiser-windowed sinc generation code, and modified OwlResampler and the NES resampler to use it. It shouldn't have any particularly noticeable end-user effects, other than slightly different startup performance(assuming no mistakes were made ). September 11, 2018: SS: Emulated input devices' internal states were not being reset on virtual power toggle; fixed. September 5, 2018: SS: Reorganized SCSP DSP emulation code to make the lifetime of variables clearer, for a possible x86_64 dynarec in the future. August 30, 2018: Modified SHA-256 hashing code to allow for piecemeal hashing of data, instead of requiring the hash to be generated from one contiguous chunk of memory. August 8, 2018: PSX: Fixed a startup crash that could occur with a malformed or corrupted SYSTEM.CNF file. July 31, 2018: Replaced MD5 hashing code with newly-written code. July 29, 2018: Replaced SDL threading code with new code that uses pthreads directly. July 28, 2018: Replaced Q subchannel CRC16 calculation code from cdrdao with newly-written code. July 24, 2018: gzip-compressed ROM/disk image files are now recognized by file extension instead of header magic. June 13, 2018: SS: Fixed an emulation inaccuracy with the handling of the SH-2 "mac.l" instruction when saturation is enabled, per tests on a SS. Download: Mednafen v1.22.0 x86
