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.

December 10, 2020: 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.

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 :p). 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. -- 1.21.3: -- April 29, 2018: SNES: Fixed an off-by-1 bug in the PPU code that would cause writing past the end of the OAM tile list array. April 24, 2018: SS: Added "House of the Dead (Japan)" to internal database of games to use the data cache read bypass kludge with, to fix a game crash on the gun calibration screen. SS: Added "Virtua Fighter Kids (Java Tea Original)" and "World Series Baseball" to internal database of games to use the data cache read bypass kludge with, to fix gameplay glitches. April 22, 2018: Removed some unnecessary memory allocations in the old settings to argument parsing glue code. Fixed a crash bug with 2xSaI-family scalers during initialization(regression introduced in 1.21.0-UNSTABLE). Create the Mednafen base directory(e.g. ~/.mednafen) before opening the lockfile to fix a startup error when the directory does not already exist(regression introduced in 1.21.0-UNSTABLE). April 21, 2018: SS: Added kludge to fix layer offset problem in "Alien Trilogy". SS: Added "WipEout" to internal database of games to use the data cache read bypass kludge with, to fix a hang that occurred when trying to exit gameplay back to the main menu. -- 1.21.2: -- April 2, 2018: Updated bundled copy of Tremor to address a security vulnerability. SS: Improved emulation of SCU DSP DMA to program RAM, per tests on a SS(still nowhere near perfect, the way it's implemented on hardware is kind of horrible, but it should work ok if games use it how it's meant to be used); fixes graphical glitches in "Shining Force III - Scenario 2", and perhaps in the other "Shining Force III" games as well. SS: Flush the prefetched SCU DSP instruction when PC is set via PPAF, instead of when END/ENDI executes or when execution is forcibly stopped, per tests on a SS. SS: Disallow SCU DSP LOP from being written in a looped single instruction unless it's the final iteration, per tests on a SS. SS: Allow SCU DSP LOP to underflow to 0xFFF with LPS and BTM, per tests on a SS. -- 1.21.1: -- March 9, 2018: Enabling the automatic save state loading/saving feature will no longer cause an error to be outputted on game load if the save state does not exist. March 3, 2018: Added support for compiling and linking with external LZO instead of the bundled miniLZO. A CD image loading hint will now be appended to the ROM image too large error message in certain circumstances. February 25, 2018: PC-FX: Added a missing variable to save states. (Re)Added backwards-compatibility "video.driver" setting value aliases. February 24, 2018: NES: Misc minor fixes for a few bootleg mappers. NES: Added missing data to VS Unisystem save states. NES: Added missing variable to mapper 64 save states. NES: Added missing save state support to the mapper 22 code. NES: Fixed improper handling of an MMC1 variable in save states. February 22, 2018: Fixed handling of the "osd.state_display_time" setting to allow a value of "0" to work as expected. -- 1.21.0-UNSTABLE: -- February 19, 2018: An attempt to run an instance of Mednafen while another instance is already running with the same base directory is now blocked during startup, via a lock file; note that this check occurs after stdout and stderr are potentially redirected to stdout.txt and stderr.txt on Windows. February 15, 2018: Changed the default value of setting "video.driver" from "opengl" to "default", removed the old "0" and "1" backwards-compatibility value aliases, renamed the "sdl" driver to "softfb"(without backwards-compat aliases), and made it so the setting's value will be reset to "default" after automatically importing settings from "mednafen-09x.cfg". On Windows, no longer exit on ALT+F4 while input is grabbed. Added settings "fps.autoenable", "fps.position", "fps.textcolor", and "fps.bgcolor". February 11, 2018: Removed reliance on malloc(), realloc(), and calloc() setting errno to ENOMEM on failure, since it's not the case on Windows XP, and possibly other platforms/operating systems too. February 9, 2018: ZIP files are now recognized by file extension instead of by magic(wizards). Replaced old minizip code with newly-written ZIP archive reading code. Replaced MDFN_PrintError() and MDFN_DispMessage() with MDFN_Notify(). February 6, 2018: Use versionsort() instead of alphasort() when scanning for js* joystick devices on Linux. February 1, 2018: Added settings "fps.scale" and "fps.font". January 31, 2018: On Windows, in-memory conversion of M3U and CUE files to UTF-8 will be attempted if they lack a UTF-8 BOM and contain byte sequences that are not valid UTF-8. On Windows, path/filename settings loaded from the old mednafen-09x.cfg(before being saved to mednafen.cfg on exit) will now be converted to UTF-8. January 29, 2018: Added support for pasting text into the cheat and netplay consoles. January 28, 2018: SS: Added Japanese keyboard emulation. SS: Improved VDP2 window Y coordinate evaluation emulation; fixes at least one background layer graphical glitch in "Radiant Silvergun"(at the start of stage 2C), and the graphical glitch near the end of the intro in "Snatcher". January 20, 2018: Altered calculations involving *.xscale(fs)/*.yscale(fs) settings to be more predictable given floating point nuances; any user using non-integer scaling values for these settings may need to adjust them to get the same result as in previous versions of Mednafen, however. Added setting "video.fs.display". January 18, 2018: SDL2(2.0.5+) is now used and required. Removed the "overlay" video driver. On Windows, error messages during startup will now be displayed in a popup message box. On Windows, Mednafen will now output text to a console if it's started from a console(e.g. cmd.exe or Cygwin), and if not, write to stdout.txt and stderr.txt like before. On Windows, Mednafen now uses Unicode variants of CRT and Win32 functions; this may require the user to convert their CUE sheets to UTF-8 if filenames use exotic(e.g. not directly typable on a standard US-layout keyboard) characters. For key bindings relating to the debugger and cheat management interface, the Right ALT key modifier will no longer be respected(only the Left ALT has any effect now), for internationalization reasons. The configuration file is back to "mednafen.cfg" instead of "mednafen-09x.cfg". If a 0.8.x "mednafen.cfg" is in the way, it will be renamed. If "mednafen.cfg" does not exist, or is from an old version of Mednafen, settings will initially be loaded from "mednafen-09x.cfg", but still saved to "mednafen.cfg" on exit(and loaded from "mednafen.cfg" from that point on). Reworked the input mapping setting format to be more human-readable(and editable). Details are in the documentation, in the "Advanced Usage" section. Old input mappings will be translated internally, except for keyboard mappings, due to incompatibilities between how SDL 1.2 and 2 handle keyboards. Added support for mapping joystick axes and buttons, mouse buttons, and keyboard keys to emulated mouse device relative motion for testing purposes(via manually editing the configuration file, as the in-emulator configuration process currently won't create such mappings). Added support for digital button input mappings that mix AND, ANDNOT, and OR-style operations together(previously it was either just AND or OR); refer to the documentation for more details. Note that the in-emulator configuration process won't create complex mappings that mix different boolean operations, but you can map combinations using simpler logic in-emulator, and then edit the configuration file to adjust the boolean operations used. January 15, 2018: SS: Fixed a bug that caused a crash if an error occurred early in the process of loading a game. Updated the configure script to disable gcc's mitigations for Spectre, in the event distributions configure their compilers to enable them by default. Stopped (erroneously) memset()'ing some MDFN_PixelFormat objects. January 12, 2018: Cleaned up the handling and reduced the size of axis-related inputs as communicated from the driver-side code to core Mednafen. PCE_FAST: Fixed fubared mouse emulation. December 28, 2017: Replaced usage of strcasecmp() and strncasecmp() with MDFN_strazicmp(), for consistent behavior across locales. Added MDFN_strazlower(), MDFN_strazupper(), MDFN_memazicmp(), and MDFN_strazicmp() functions. December 14, 2017: SS: Fixed a logic error in the BIOS sanity check code that caused it to throw a less helpful error message than intended in certain circumstances, and made the error messages related to BIOS file misconfiguration more verbose(and hopefully more helpful...). December 6, 2017: Fixed broken cheat file saving on MS Windows. November 12, 2017: Changed how some multidimensional arrays and arrays of structs are accessed, to try to avoid behavior that's probably undefined and may be a problem in the future. PC-FX: Fixed integer overflows that caused fatal division by zero when Mednafen's cheat functionality was used(a regression introduced around 0.9.39). SS: Stuck SCU DMA table arrays in a struct to avoid unspecified behavior in the SCU save state code. -- 0.9.48: -- September 16, 2017: Set cheat's default endianness to that preferred by the system being emulated when manually adding a cheat that's not a cheat device code nor the result of a cheat search. September 15, 2017: SS: Fixed SCU DSP DMA from B-bus; fixes the periodic loud popping in Grandia's FMV. September 12, 2017: SS: Added a hack/kludge to allow bypassing of data cache on reads(such that the timing benefits of partial cache emulation are preserved, without cache coherency problems that partial cache emulation sometimes leads to with poorly programmed games), and added an internal database to enable it on select games; fixes graphical glitches and/or hangs in "Area 51 (USA and Europe)", "Clockwork Knight 2 (USA)", "DeJig - Lassen Art Collection", "Father Christmas", "Golden Axe The Duel", "Sega Saturn Choice Cuts", "Spot Goes to Hollywood (USA and Japan)", "Street Fighter Zero", "Street Fighter Zero 3", "Super Puzzle Fighter II Turbo", and "Virtual Volleyball". SS: Full cache emulation is now enabled for "Whizz"(by using an internal database), to resolve(or at least reduce) quasi-random hanging issues during startup. September 11, 2017: SS: Corrected an inaccuracy with CDB play repeat handling; fixes hang when trying to resume a suspended game in "Tactics Ogre". SS: Initialize VDP1 clipping and local coordinate registers only on power-on, and not on reset. September 7, 2017: SS: Fixed side-effect inaccuracies in the CDB Put Sector Data, Copy Sector Data, and Move Sector Data command emulation. September 6, 2017: Added configure option "--with-external-trio", for distribution packagers. SS: Added partial emulation of SH-2 external bus open bus behavior; fixes messed up colors in "Discworld 2". September 4, 2017: SS: Improved CDB Initialize command emulation; fixes crash in "Tenchi Muyou! Ryououki Gokuraku" when it tries to play an opening movie during startup. August 28, 2017: SS: Made CD seek overhead calculation less completely wrong; fixes graphics corruption in intro of "Batman Forever", and fixes hang in "Jung Rhythm" when trying to retry a failed stage. -- 0.9.47: -- August 25, 2017: Lynx, MD, NGP, SMS: Added a few missing variables to save states. August 24, 2017: SS: Added save state support. Revamped save state helper macros and functions, to allow save-stating of variables in arrays of structs to be simpler. August 22, 2017: SS: Fixed BCR1 write protect, and added stub emulation of the other BSC registers. SS: Added incomplete stub Action Replay 4M Plus emulation(for experimentation); proper Action Replay support would require SH-2 UBC emulation, and that may be too costly performance wise. August 21, 2017: SS: Implemented very rough approximation of bus timing side effects when master SH-2 DMA is active(accurate handling of bus priorities and sharing would increase CPU requirements noticeably, but it may ultimately be necessary as a database-driven option for some stubborn games in the future). Fixes startup hangs in "Device Reign", "Real Sound", "Resident Evil", "SD Gundam G Century S", "Super Tempo", "Tennis Arena", "Tilk", "Yuukyuu Gensoukyoku", "Yuukyuu Gensoukyoku 2nd Album", "Yuukyuu Gensoukyoku ensemble", "Yuukyuu Gensoukyoku ensemble 2", "Yuukyuu no Kobako Official Collection", and "Zero4 Champ". -- 0.9.46: -- August 10, 2017: Compile with explicit -fstrict-aliasing, for distributions/OSes that have configured gcc to not enable strict aliasing at -O2(and possibly other levels). Fixed a bug that could, under certain conditions, cause emulator OSD elements to not be updated in the time after entering frame advance mode and before a frame advance. August 7, 2017: Use a sorted std::vector instead of std::multimap to store current settings, to reduce memory usage. August 6, 2017: SS: Added ss.input.port*.3dpad.mode.defpos settings to control the default position of the digital/analog mode switch. August 5, 2017: Allow addresses above FFFF to be entered as the logical watch address in the debugger. August 4, 2017: SS: Added kludge to fix layer offset problem in "Daytona USA CCE". NES: The functionality controlled by setting "nes.fnscan" now recognizes "(F)" and "(France)" as PAL. NES: Added support for iNES mapper 40. July 11, 2017: Utilize _byteswap_*() functions in endian.h when compiling with Microsoft's C++ compiler. June 22, 2017: Fixed a couple of minor issues(log header formatting, and skipped logging of first instruction in step mode) with the debugger's undocumented trace log feature. NES: Corrected the period of PAL noise channel frequency setting 0x1. June 21, 2017: NES: Fixed a few square wave sound channel emulation bugs(wrong phase for duty setting 3, and failing to clock the period counter when the channel is silenced). -- 0.9.45.1: -- June 5, 2017: SNES: Fixed an instance of possibly-undefined behavior. Silenced dumb warning spam relating to endian.h emitted by newer versions of gcc. June 4, 2017: Fixed garbled audio with the exclusive-mode WASAPI sound driver on some higher-end sound cards(regression introduced in 0.9.45 due to a mistake in changing the meaning of a macro field during development); may also fix garbled audio when using the new OpenBSD sound driver with certain sound cards. -- 0.9.45: -- May 29, 2017: Tweaked netplay sound buffer underrun kludge code. The netplay server host and port being connected to are now printed to the netplay console at the beginning of a connection attempt. Netplay connection attempts to servers are now non-blocking. May 25, 2017: SS: Synchronize end of SMPC clock change commands to beginning of vsync instead of beginning of vblank, per tests on a SS. May 23, 2017: SS: Reworked how the VDP2 rendering thread waits, to make Saturn emulation usable with the default OpenBSD kernel. SS: Added emulation of the light gun("Stunner"/"Virtua Gun"). April 28, 2017: #include'd many commonly-used C and C++ standard library headers in types.h(and removed redundant #include statements from various header and source files), to reduce the probability of portability problems(due to neglecting to explicitly include a header file) when different standard C/C++ libraries behave differently in regards to what header files include what other header files. Added a sound output driver for OpenBSD's /dev/audio. Reworked the sound output format conversion code to be more versatile, April 25, 2017: NES: Wrote new "Barcode Battler II" emulation code to replace the old "Barcode World" code, based on quick testing with actual hardware(albeit the English version). April 24, 2017: SSFPlay: Added save state support. -- 0.9.44.1: -- April 21, 2017: MD: Added a missing MDFN_FASTCALL, the absence of which broke 32-bit x86 builds(either at link time or run time). -- 0.9.44: -- April 19, 2017: PSX: Restructured the GPU emulation code and data a bit to get a minor performance boost. April 18, 2017: VB, PCE, WonderSwan, MD, GBA: Use fastcall calling convention(on 32-bit x86) in a few (more) places where it makes sense. April 16, 2017: SNES-Faust: Added setting "snes_faust.correct_aspect", default value of "1". SNES-Faust: Added PAL support. April 14, 2017: SNES-Faust: Made minor optimizations to the BG rendering code. April 9, 2017: Added command-line option "-which_medium", to specify which CD to start with when using multi-CD M3U sets. April 5, 2017: SNES: Fixed emulator hang when saving state in "Panic Bomber W". April 3, 2017: Added some simple scripts to cross-compile and package Mednafen for Windows. Added Windows cross-compiler toolchain setup notes. 32-bit Windows builds are now compiled with -march=i686 instead of -march=i586(shouldn't affect compatibility for official builds, since the toolchain and libraries were already effectively being compiled with -march=i686, which was not intended, but since nobody apparently complained... ;p). March 25, 2017: VB: Added support for custom palettes. VB: Reworked how LED on-state duration is translated into RGB values and added setting "vb.ledonscale"; the default value of "vb.ledonscale" is set such that the overall brightness will be lower than in previous versions of Mednafen, to reduce white crush, but the user can set it to a value of "1.9921875" to approximate the old brightness level. March 20, 2017: SNES: Made a couple of SDD1 registers readable; fixes "Tractor Beam" spell graphical glitches in "Star Ocean"(thanks to orbea). March 17, 2017: SS: Added support for a 16MiB RAM cart mapped into the A-bus CS1 area(for "Heart of Darkness" and homebrew). March 15, 2017: WonderSwan: Removed setting "wswan.rotateinput", and added a new device("gamepadraa") that can be selected on virtual input port 1 to automatically rotate inputs when the display is rotated. March 14, 2017: Reworked text drawing to not use an excessive number of potentially-large VLAs. Moved statements with important side effects outside of assert()s in settings.cpp. Replaced ancient Unicode conversion code with newly-developed code. March 7, 2017: SS: Prioritize SMPC command execution over VBlank handler execution, per (limited) tests on a SS. Fixes broken input in "Primal Rage"(a 0.9.43 regression). -- 0.9.43: -- February 24, 2017: Reworked how input grabbing is handled. The new way uses only one key combo(CTRL+SHIFT+Menu), and will adapt its behavior based on any keyboards being selected on any virtual input ports or not(refer to the documentation for full details). A new setting is added, "command.toggle_grab", and two settings were removed, "command.toggle_grab_input" and "command.toggle_cidisable". Emulated keyboard(FKB, Tsushin, Saturn) key state is now only updated when input grabbing is toggled on. February 22, 2017: SS: Fixed SMPC read handling of an empty input port. SS: Implemented emulation of SMPC 0-byte port read mode. PSX: Reduced rumble latency by 1 frame. February 20, 2017: Reworked how keyboard key state is handled, to prevent extremely short button presses from being lost(like what can happen with the Pause key, or other keys when slow-forwarding is active). SS: Added 101-key US keyboard emulation. February 17, 2017: SS: Allow SMPC commands to be dual-issued; fixes hang in "F1 Challenge", and hangs/missing sound in "Magic Knight Rayearth". SS: Added emulation of the 6-Player Adaptor(multitap). February 15, 2017: SS: Added emulation of the Mission Stick and Dual Mission Sticks. February 13, 2017: SS: Added emulation of the steering wheel("Arcade Racer"), for use with "Virtua Racing", "High Velocity - Mountain Racing Challenge", "The Need for Speed", and other Saturn racing games that apparently lack 3D pad support. -- 0.9.42: -- February 7, 2017: SS: Ignore lower bit of VDP1 sprite draw command texture base address when drawing using color mode 5, per tests on a SS; fixes some of the graphical glitches in "All-Star Baseball 97". February 6, 2017: SS: Ignore writes to VDP1 registers via SCU DMA under certain conditions to approximate what happens on a SS; fixes hang in "GunBlaze-S". SS: Fixed handling of RSTCSR WOVF clearing, per tests on a SS. Also changed the semantics of RSTCSRM a bit to simplify things, might want to change WTCSRM, FTCSRM, etc. semantics too in the future for consistency... SS: Fixed handling of WTCSR OVF clearing, per tests on a SS. Updated tremor to revision 19427. Updated libogg to version 1.3.2. Fixed a bug that caused a crash if the user tried to select(via CTRL+SHIFT+[n]) a device on a non-existent virtual input port. February 5, 2017: SNES-Faust: Added multitap support. February 3, 2017: SS: Fixed a bug in the handling of M68K level 7 interrupts; fixes missing sound in "Arcade's Greatest Hits". February 1, 2017: SS: Suspend VDP1 command processing while an SCU DMA from SDRAM to VDP1 VRAM is active, to approximate how a SS behaves. Fixes FMV tearing in "Johnny Bazookatone", and fubared graphics in "Virtua Cop" and "Virtua Cop 2". January 31, 2017: SS: Fixed handling of clearing FTCSR bits, per tests on a SS. January 30, 2017: SS: Improved instruction timing(though still far from perfect); fixes speed problems in "Pocket Fighter", reduces the size of the flickering area in "Lunar"'s FMV, and fixes the crash that occurs immediately after gameplay starts in "Virtua Fighter" and "Virtua Fighter Remix". January 26, 2017: NES: Added support for iNES mapper 190. January 25, 2017: SS: Clear SCU internal pending interrupt bit upon the SCU's acceptance of the IRQ to send to the SH-2, instead of when the SH-2 fetches the vector, per tests on a SS. -- 0.9.41: -- January 21, 2017: SS: Implemented disc change IRQ on disc eject. January 20, 2017: Replaced usage of trio_snprintf() to a fixed-size buffer for path construction in general.cpp with manual concatenation of std::string strings. January 18, 2017: Use _beginthreadex() instead of CreateThread() on Windows, to avoid a small memory leak. Now explicitly use 64-bit walltime functions on 32-bit Windows builds. January 17, 2017: PCE, PCE_FAST: Added a missing sound emulation variable to save states. January 16, 2017: SNES: Added setting "snes.h_blend", default value of "0", that when set to "1" will enable a horizontal blend/blur filter. January 15, 2017: PCE: Improved SuperGrafx window handling in 10MHz dot clock modes. GBA: Modified RTC emulation to not use standard C library walltime functions during emulation. Wrapped various time functions, and dropped the dependencies on SDL time functions, in Time.cpp/Time.h. January 14, 2017: WonderSwan: Fixed off-by-1 bugs in window coordinate evaluation, per tip from trap15. WonderSwan: Fixed copyright notice headers to not allow distribution under versions of the GPL other than version 2(an oversight from back when the Cygne code was added to Mednafen). WonderSwan: Applied sound and DMA emulation fixes from trap15; fixes rain sound effect in "Star Hearts". The changes did necessitate lowering the overall WonderSwan sound emulation volume a bit to prevent excessive clipping, however. January 12, 2017: SS: Fixed a logic error in the VDP2 rendering code; fixes battle scenes in "Grandia". January 10, 2017: SS: Removed a few bad entries in the internal region-correction database that were breaking the Korean releases of some games. January 9, 2017: PCE, PCE_FAST: Added support for auto-enabling SuperGrafx emulation with CDs when a mode 1 data track has the 16-byte magic "4D 65 64 6E 61 66 65 6E 74 AB 90 19 42 62 7D E6" at offset 0x86A(assuming 2048 bytes per sector), for homebrew and translations. January 7, 2017: SS: Added emulation of the SCSP 18-bit DAC enable bit; fixes low volume problem in "Daytona USA". SS: Fixed some bugs that broke emulation on big-endian platforms. January 5, 2017: Fixed an off-by-1 memory corruption bug in the debugger's memory editor relative bytestring search code. VB: Finally commented out some debug printf()s. January 1, 2017: Cleaned up code that passes video data from the game thread to the main thread, and replaced some volatile usage with atomics. December 31, 2016: Fixed a large memory leak that occurred when saving screenshots with SHIFT+F9. VB: Fixed a regression introduced in 0.9.39.2 that caused transient sound/note distortion on save state load. December 27, 2016: Moved TCP/IP networking code into the core of Mednafen, and added support for non-blocking connects, so the Saturn emulation module can eventually use it for modem emulation. December 25, 2016: Modified configure script to (hopefully) compile in the Saturn emulation module when building for PPC64 and AArch64 architectures(in addition to x86_64). December 21, 2016: Allow emulated digital button mappings to be used in AND mode(like command keys configured with SHIFT+F2) if the user manually prefixes the "/&&\ " magic string to the mapping setting string in the configuration file. Can be useful with emulated switches and mode toggle buttons, but the in-emulator input configuration process will need to be revamped before enabling this mode for a mapping can be done in a sane and more user-friendly manner. Rewrote round_up_pow2() in math_ops.h to use MDFN_log2, which in turn uses MDFN_lzcount*(), since the major CPUs that Mednafen is going to run on should have dedicated instructions to (at least indirectly) count leading zeroes. Also changed the semantics to return 0 on overflow instead of 1. December 20, 2016: SS: Now use leading-zero counting function from math_ops.h in the VDP2 rendering code, instead of using inline assembly. Reorganized the leading/trailing bit counting functions in math_ops.h, added 32-bit and 64-bit trailing-bit counting functions, and added faster variants where passing a 0 results in an undefined result. December 19, 2016: Print out the game key used after a connection is established with netplay, when the game key is not empty. SMS: Added settings "sms.slstart", "sms.slend", "sms.slstartp", and "sms.slendp". Added some checks to help prevent a black screen when the scanlines effect is enabled via a
