Mednafen

-- 1.32.1: --
March 15, 2024:
	Apple2: Fixed erroneous parsing of WOZ file padding bytes and unknown chunks' data as 8-byte chunk headers.

-- 1.32.0-UNSTABLE: --
December 29, 2023:
	Silently disable keyboard grabbing temporarily while the netplay text input, debugger, or cheat interface is active, to
	avoid complicated text input problems with AltGr and low-level keyboard hooks on Windows.
December 25, 2023:
	Fixed directory creation error(s) when trying to run Mednafen in the root directory of a (non-subst'd) drive on Windows,
	a regression introduced in 1.22.0-UNSTABLE.
December 24, 2023:
	PSX: Added support for Konami's "Pop'n Music" controller.
December 22, 2023:
	Added setting "input.grab.strategy" to control when the system keyboard and mouse are grabbed while input grabbing is
	toggled on in Mednafen.  Note that SDL2 2.0.16 or later is required for the non-default "auto" option to fully work.
December 18, 2023:
	Fixed excessive CPU usage when sound is disabled or fast-forwarding is active while in frame advance/pause or in the
	cheat interface.
December 17, 2023:
	No longer set environment variable "__GL_SYNC_TO_VBLANK", instead relying only on SDL_GL_SetSwapInterval(),
	as it seems to work fine nowadays with Nvidia's binary Linux driver, to avoid thread safety issues with
	environment modifications.
	Renamed configuration macro "PSS_STYLE" to "MDFN_PSS_STYLE", and path-separator string macro from "PSS" to "MDFN_PSS".
December 15, 2023:
	PSX: Renamed setting "psx.dbg_level" to "psx.dbg_mask", and changed its type to a multi-enum, to allow for more granular
	enabling of debug messages.
	Added SettingsManager::GetMultiM() and MDFN_GetSettingMultiM() functions, which will return the setting's enum
	values OR'd together.
	abort() when SettingsManager::GetUI(), SettingsManager::GetI(), or SettingsManager::GetF() is called for
	a MDFNST_MULTI_ENUM-type setting.
	PSX: Snoop additional BIOS tty stdout functions when setting "psx.dbg_level" is 2 or higher.
December 2, 2023:
	Patched SDL2 in the Windows build toolchain to ignore synthetic Left CTRL key events generated by AltGr,
	when keyboard input grabbing is active.
	Demo: Added an interactive graphical keyboard test mode to check input grabbing and SDL2 keyboard support,
	among other things, activated by changing the value of new setting "demo.mode" to "keyboard".
November 29, 2023:
	PCE, NES: Fixed broken rendering in the graphics debugger when the OSD pixel format is not the same as the emulation
	video pixel format.
November 28, 2023:
	Changed the OpenGL RGB555 support(e.g. via the "video.glformat" setting) to use a pixel format and type of
	GL_RGBA and GL_UNSIGNED_SHORT_5_5_5_1(instead of GL_BGRA and GL_UNSIGNED_SHORT_1_5_5_5_REV as before).
	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.
	Fixed hang when a post-startup error occurred during video reinitialization or blitting, due to erroneously unlocking
	a mutex twice.
November 23, 2023:
	Updated toolchain for official Windows builds(non-Win9x):
		binutils 2.28 -> 2.28.1
		flac 1.3.2 -> 1.3.4
		mingw-w64 5.0.3 -> 5.0.5
		SDL2 2.0.8-11835 -> 2.28.5
		zlib 1.2.8 -> 1.2.13
	Additionally, the 32-bit build of SDL2 has been patched to restore support for Windows 2000, broken since the migration
	to SDL2 in Mednafen 1.x.
November 21, 2023:
	Apple2: Delay Disk II processing of normal flux pulses vs. random noise pulses, and disable the 500ns delay
	pseudorandomly(50% probability) added to normal pulse detection, as it breaks WOZ dumps of "Test Drive" and "Wizardry".
November 19, 2023:
	Fixed design flaw in MDFN_strargssplit() that broke handling of an escaped backslash immediately preceding a closing
	double quote character.
November 18, 2023:
	Documentation: Added support for hyperlinks to settings in the description text for settings, custom palettes, and
	internal databases, by enclosing the setting name in double quotes and prefixing the name with ASCII control
	character 5.
	Fixed broken handling of octal along with a few edge case issues in MDFN_strunescape().
	In MDFN_strescape(), escape control characters in 3-digit octal instead of 2-digit hex or 1-digit octal to avoid
	potential conflicts with subsequent characters.
October 21, 2023:
	Align QTRecord CSCD video codec line data to 4-byte boundaries, as is correct, to fix broken recorded video in some
	circumstances.

	32MiB or smaller, and force full cache emulation to be enabled when running with a bootable ROM cart image.
	SS: When loading a save state, mark internal and cart backup memories as dirty only if loading the state actually
	changed them, to try to avoid excessive disk writes when using state rewinding.
	SS: Added support for routing SCSP MIDI output to stdout, activated by changing the value of the new "ss.midi" setting to
	"stdout". Note that byte values of 0x1B will be filtered from the output, and timing synchronization issues limit
	its uses outside debug text output. 
October 12, 2023:
	SS: Corrected behavior of VDP2 color calculation blending when in both hires mode and a non-zero color RAM mode.
October 11, 2023:
	SS: Prevent VDP2 color calculation blending with a transparent sprite shadow pixel beneath the topmost layer;
	fixes erroneous opaque red shadows under units during the last episode's first battle in "Sakura Taisen".

	to fix octopus screen flickering.
September 22, 2023:
	Apple2: Error out when loading WOZ 2.1-format images with FLUX chunks, as they're not currently supported.
September 21, 2023:
	Apple2: Added "rgb_video7" video rendering mode, which supports the additional graphics modes offered by the Apple IIe
	Video 7 RGB interface, one of which is used by Sierra's AGI games, and provides two distinct grays in all graphics modes.
September 14, 2023:
	Apple2: Added "apple2.input.kb.auto_repeat" setting.
	Debugger: In the memory editor, the Escape key will now exit text entry prompts and editing mode.
	Debugger: Don't set a register's value to 0 when the register edit text entry string is empty or completely invalid.
September 13, 2023:
	Fixed bug that could cause nearly all hotkey/command key functions to trigger spontaneously when Mednafen has been running
	for around 49.7 days
	Changed the default mapping for exit to just F12 instead of ESC and/or F12.
	Added a new hotkey for closing the netplay popup, by default mapped to "ESC", controlled by setting "command.close_popup".
September 10, 2023:
	Apple2: Added "rgb_qd" and "rgb_qd_tfr" video rendering modes, which will render DHGR at quarter-resolution, and provide
	two distinct grays in all graphics modes.
September 9, 2023:
	Apple2: Renamed keyboard input mapping settings to reduce their lengths, and documented the caps lock default position setting.
	Apple2: Changed how HGR is handled with the "rgb_alt" and "rgb_alt_tfr" video rendering modes, for consistency with DHGR
	and to correct a few glitches.
August 31, 2023:
	Apple2: Added an adjustable composite color video sharpening filter, controlled by the new setting "apple2.video.postsharp".
May 7, 2023:
	SNES-Faust: CPU writes to VRAM during active display are now blocked. Fixes missing dialog box and text in
	"Mazinger Z", title screen corruption in "NBA Pro Basketball: Bulls vs Blazers" and
	"Shin Nihon Pro Wrestling: Chou Senshi in Tokyo Dome", and graphical garbage during startup in "Zen-Nihon Pro Wres".
	May break ancient ROM hacks and fan translations.
April 17, 2023:
	Include general mode(read, write, read+write) in file open error messages.
April 12, 2023:
	Added command-line option "-ovconfig", to load global override settings from the specified file. The global override settings
	will override any settings loaded from "mednafen.cfg" or set via command-line arguments, but will be overridden in turn by
	more-specific per-module and per-game override configuration files.
April 4, 2023:
	Apple2: Added high-level(no seek delay) ProDOS-compatible hard disk drive emulation, usable by loading a raw hard
	disk drive image with an "hdv" file extension, and through the "hdd" directive in a MAI file.
March 28, 2023:
	Apple2: Added support for Apple IIe and Enhanced IIe, selectable via changing the new "apple2.model" setting, or
	by utilizing the new "model" directive in a MAI file.
	Apple2: When loading a floppy disk image from a ZIP archive without a MAI file, all other floppy disk images with the same
	extension in the same directory in the ZIP archive will now also be loaded automatically. If desired, this feature can be
	disabled by setting the new "apple2.multiload" setting to "0".
March 26, 2023:
	Apple2: Added setting "apple2.input.kb.ghosting", default value of "1", that can be set to "0" to disable emulation
	of spurious ghost keypresses.
March 25, 2023:
	Apple2: Increased the maximum value of the "apple2.video.color_smooth" setting to "2", which will enable more-aggressive
	composite video color smoothing.
March 6, 2023:
	Use AX_APPEND_COMPILE_FLAGS() instead of AX_CFLAGS_GCC_OPTION() in the configure script.
February 24, 2023:
	SS: Enable data cache bypass kludge for "Kanzen Chuukei Pro Yakyuu Greatest Nine (Japan)", to fix game hangs.

	in "Wordtris".
September 4, 2022:
	SNES-Faust: Fixed distorted graphics in "Marvelous" and "Bishoujo Janshi Suchie-Pai" due to hires color math emulation
	inaccuracies.

	SS: Trigger mid-frame synchronization when going into vblank if not already triggered by SMPC INTBACK command processing.
March 26, 2022:
	SS: When VDP2 per-dot RBG0 coefficient reading is enabled, and a per-dot coefficient read is attempted from a memory region not configured for that purpose
	via RDBS, force the coefficient data to 0, instead of using the per-line coefficient data.  Fixes graphical glitches in "Radiant Silvergun" when starting
	a new game after interrupting the attract mode during the AKA-O battle.
March 23, 2022:
	SS: Forcibly disable NBG1-3 only if both RBG0 and RBG1 are enabled via BGON, instead of only checking if RBG1 is enabled; fixes missing/glitchy graphics
	in "Houkago Ren'ai Club: Koi no Etude".
March 9, 2022:
	SNES-Faust: Fixed broken ExLoROM support.
	PCE, PCE-Fast, PC-FX:  Update channel 1 frequency cache upon LFO frequency register writes(the way the channel 1 frequency and LFO frequency are combined
	is still inaccurate, however, causing frequency update timing granularity to be too high).
February 4, 2022:

-- 1.29.0: --
January 12, 2022:
	PCE, PCE-Fast: Initialize VCE color table memory at power-on to roughly(without probabilistic bit randomness) match test results from a
	PC Engine Duo instead of just zeroing it; fixes unreadable letters in the password entry screen of "Order of the Griffon".
	Added test for potential splatting-related bug in qemu's PPC64 VSX "xscvdpsp" instruction emulation that messes up OwlResampler when compiled with gcc.
January 11, 2022:
	PCE: Added patch in the "notes" subdir for extending the upper range of the "pce.slend" setting to 241(not applied in Mednafen due to increasing
	the probability of an extra 8ms of input lag with some games).
January 9, 2022:
	VB: Fixed a couple inaccuracies in the VSU modulation emulation, fixing a few sound effects in "Virtual Boy Wario Land".

December 5, 2021:
	Placing a "%d" or "%b" specifier at the beginning of a filesys.fname_* setting format string will now cause the generated path to be used as-is, rather
	than potentially being prefixed with the corresponding filesys.path_* setting or the Mednafen base directory.  Fixes a regression introduced in
	1.28.0-UNSTABLE that caused IPS patch files to be loaded from the wrong location when the user had loaded a game via a relative path.
November 29, 2021:
	Added support for playing the SCSP-generated music from most Sega Model 2A, 2B, 2C, and 3 games, via the new experimental "sasplay" module.
