audio that leads to a hang in the "Tenshi no Uta" game.
SNES-Faust: Extended DMA NMI delay kludge to cover 8-bit LDX #imm to fix hang in "Frisky Tom" in "Nichibutsu Arcade Classics".
SNES-Faust: Added DSP-2 emulation.
November 19, 2019:
SNES-Faust: Added MSU1 support.

November 17, 2019:
On Windows, call CoInitializeEx() with COINIT_MULTITHREADED before calling SDL_Init(), to prevent potential initialization errors with Mednafen's
WASAPI sound code.
November 16, 2019:
Using drive-relative paths on Windows should no longer make a mess due to Mednafen looking for and putting files in the wrong place.
November 14, 2019:
SS: Removed "ss.midsync" setting; the functionality it controlled is now always enabled.
Added settings "affinity.cd", "affinity.emu", "affinity.video", and "ss.affinity.vdp2" to specify CPU thread affinity masks for the CD read threads,
main emulation thread, video blitting thread, and Saturn VDP2 rendering thread, respectively. Setting thread affinities properly can improve
Saturn emulation performance on a dual-core CPU with hyperthreading.
Cleaned up multithreading code and API.
November 10, 2019:
Removed "using namespace Mednafen;" from types.h, and related changes.
October 25, 2019:

Implemented workaround in OwlResampler_neon.inc for a C++ parsing bug in gcc 9.x.
September 13, 2019:
Apple2: Renamed(with backwards-compatibility aliases) video mode "rgb_alt1" to "rgb_alt" and "rgb_alt2" to "rgb_alt_tfr", and added new video mode "rgb_tfr".

August 26, 2019:
Apple2: Added support for an RGB-style video mode, selectable with the new setting "apple2.video.mode".
SS: Added "Shunsai" to the internal database of games to use the data cache read bypass kludge with, to fix various graphical glitches.
August 25, 2019:
Expanded and harmonized the accepted value ranges for settings "sfspeed" and "ffspeed" to 0.25 through 15, for greater versatility.
NGP: Added very incomplete emulation of BIOS system call "VECT_FLASHERS", per tip from stellarporter. Fixes eventual hang in "The Last Blade".
NGP: Fixed TLCS-900H new IFF calculation when taking an interrupt, per tip from trinemark. Fixes broken voice playback in
"Densetsu no Ogre Battle Gaiden".
NGP: Fixed potential division by zero in the TLCS-900H MINC* and MDEC* instructions emulation(the emulation of the instructions is still almost certainly wrong,
though), per tip from byuu.
August 24, 2019:
PCE: Changed the Super CD-ROM^2 memory identification signature to match a Duo instead of a PCE with a system card, to fix compatibility
issues with some US Super CD-ROM^2 games when using a US system card image, per tip from elmer.

select screen.
June 16, 2019:
SS: Slowed down SCU DMA from SDRAM/SH-2 bus slightly, though I'm not sure what is the origin of the measured overhead/slowdown on a Saturn.
Fixes FMV flickering in "Lunar".
SS: Added partial emulation(CS0 and CS1, SH-2 non-DMA accesses and SCU DMA accesses) of the timing effects of the SCU A-bus configuration registers.
SS: Added "Tech Saturn 1997.6" to the internal database of games for which 1MiB RAM cart emulation is enabled, for its "Groove on Fight" demo.
SS: Implemented a crude simulation of the VDP1 command execution slowdown that occurs when an SH-2 CPU writes to VDP1 RAM or registers, activated
via the horrible hacks mechanism; fixes text flickering in "Arcade's Greatest Hits", most rescue text flickering in "Burning Rangers"(at least on the first stage),
graphical glitches in "Whizz", and some of the graphical glitches in "All-Star Baseball 97".
SS: Added a horrible hack to fix the hang in "Fighters Megamix" that occurred after the intro FMV played(or was interrupted).
SS: Added a horrible hack to fix the hang at the end of disc 1 of "Grandia".

SS: Full cache emulation(enabled via database) now also enables emulation of SH-2 WB/EX pipeline stalls.
SS: Tweaked the kludgey CPU instruction read/write penalty during SH-2 DMA to be higher in some circumstances; fixes major graphical glitches in the
later stages of "Shienryu" when on arcade mode.
SS: Added "Dragon Force II" to the internal database of games to use the data cache read bypass kludge with, to fix major game logic errors
during battles.
