Log Message:
mednafen: update to 1.27.1.

-- 1.27.1: --

June 4, 2021:
	SS: Added "Herc's Adventures" to the internal database of games to \ 
enable SH-2 read/write VDP1 draw slowdown with, to fix a few graphical glitches.

May 28, 2021:
	Error out in the configure script when iconv is not found, rather than later \ 
during compilation.

May 26, 2021:
	SNES: Applied untested fix for an issue with libco on PPC64 ELFv2 systems.

May 18, 2021:
	SS: Corrected a few inaccuracies in the handling of SCSP EG phase transitions, \ 
per tests on a SS.

May 12, 2021:
	Renamed intl/VERSION to intl/VERSION.txt to prevent a conflict with a system \ 
C++ header file on case-insensitive filesystems(problem introduced in \ 
1.27.0-UNSTABLE).

April 29, 2021:
	Demo: Use #pragma(pack) instead of __attribute__((packed)), to work around a \ 
bug/design flaw in older versions of gcc that caused the demo module's save
	state test to fail when compiled for a Windows target(where ms_struct is the \ 
default structure layout).

April 28, 2021:
	Increased verbosity of bad Q subchannel data error messages in the CloneCD CD \ 
image loader.

	Fixed crashing with non-glibc iconv implementations when the user specifies an \ 
unsupported character encoding in the debugger's memory editor.

-- 1.27.0-UNSTABLE: --

March 29, 2021:
	SS: Corrected threshold and semantics of envelope level-based blocking of \ 
slots' access to SCSP RAM, per tests on a SS.

March 13, 2021:
	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".

March 12, 2021:
	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.

March 9, 2021:
	VB: Block writes to VSU registers and memories when A0 and A1 are not both 0, \ 
per tip from "enthusi".

March 7, 2021:
	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.

March 4, 2021:
	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".

February 23, 2021:
	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.

February 19, 2021:
	SNES-Faust: Reworked cart header detection and cart type detection logic a bit, \ 
fixes "Yuuyu no Quiz de Go! Go!".

February 17, 2021:
	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".

February 16, 2021:
	SNES-Faust: Changed power-on APU RAM initialization pattern; fixes hangs in \ 
"Ihatov Monogatari" and "Kyuuyaku Megami Tensei".

February 3, 2021:
	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.

January 31, 2021:
	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.

January 28, 2021:
	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.

January 25, 2021:
	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.

January 24, 2021:
	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.

January 19, 2021:
	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.

January 12, 2021:
	Added "upper_center" and "center" options to the \ 
"fps.position" setting.

January 7, 2021:
	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.

January 6, 2021:
	SMS: Sanitize more variables on state load.

	NES: Fixed a few instances of missing variable initialization on poweron.

January 5, 2021:
	GB: Sanitize a few variables on state load.

January 4, 2021:
	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.

January 2, 2021:
	NES: Sanitize more sound emulation variables on state load.

January 1, 2021:
	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.

December 31, 2020:
	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.

December 30, 2020:
	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.

December 29, 2020:
	Optimized MDFN_FastArraySet() for non-ideal counts.

	Utilized MDFN_HIDE in more places.

December 28, 2020:
	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.

December 25, 2020:
	PSX: Initialize some missed state on reset/poweron.

December 24, 2020:
	Completely rewrote the save state preview image resizing code, so that now it's \ 
only somewhat wrong, instead of mostly wrong as before.

December 22, 2020:
	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.

December 20, 2020:
	Birthed pernicious human date/time calculation functions to replace the usage \ 
of _gmtime64() and _localtime64() on Windows, for Windows 9x compatibility.

December 14, 2020:
	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.

December 12, 2020:
	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.

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.

December 1, 2020:
	Made various changes to the Windows support code, to allow for compiling a \ 
non-Unicode Windows build.

November 24, 2020:
	Implemented stream buffering in the FileStream class, now using read(), \ 
write(), etc. instead of fread(), fwrite(), etc.
