- ES8712 sound: The ES8712 is actually a controller for MSM5205/MSM6585 and 74157-type TTL pair (gcpinbal.cpp, lastbank.cpp, metro.cpp and witch.cpp). Added notes.
- K051649 sound: Added scc_map to reduce duplication in driver memory maps
- N2A03 APU sound: Derive frame counter from clock input
- Namco C352 sound
  . Changed mu-law algorithm to match Namco's WII VC emulator. This appears to be the original algorithm used in the hardware. 
  . Fixed static noise between fights in Tekken 3
  . Fixed the order of the phase inversion flags
- QS1000 sound: Converted set_irq into WRITE_LINE_MEMBER
- QSound
  . Rewrote/Improved DSP16 disassembler. Less ambiguous, more like the manual. Less cluttered output, better handling of ambiguous operations, look-ahead for predicated jumps, live will/won't comments on conditional instructions (cpu\dsp16\dsp16dis.cpp).
  . Cycle-accurate DSP16 core (disabled in QSound for performance reasons). Start adding DSP16 recompiler boilerplate.
  . QSound LLE available with a 3-character change. Changed sample rate and playback behaviour to better match DSP for qsound_hle. Simplified sample fetch/scale and register writes for qsound_hle.
  . Clean up host and DAC comms a bit, hopefully fix desync (sound\qsound.cpp).
  . Marginal DSP16 performance improvement by precalculating SIO clock divider preload, also push ILD/OLD on mode change. Moved most core state into DRC cache - keeps a lot of details out of the main header (DRC is still stubbed out).
- Sega PCM sound: De-staticify initializations. Added device_clock_changed. Minor cleanup (sound\segapcm.cpp; drivers\segahang.cpp, segaorun.cpp, segaxbd.cpp and segaybd.cpp).
- Taito Ensoniq Sound System
  . Moved imperfect_features() into es5510.h. Verified ESP input clock and output channels from GunBuster schematics (same in other PCBs?). Added m_bankmask instead runtime tag lookups. Added notes.

  . Ensoniq 5505/5506 to 5510 interface (sound\esqpump.cpp): Cleanup unused m_otis/m_otto and converted e[0x4000] into std::unique_ptr if used.
- ER2055 EAROM: Separated CLK writes to make emulation usable for (MESS) CIT-101
- Intel 8251 USART: Added XMIT FLAG polling to (MESS) DEC VT100 using new i8251 line read handler
- Intel 8253 PIT: Converted counters to subdevices
- Kaneko Custom: Added device_rom_interface instead memory pointer (video\sknsspr.cpp; drivers\galpani3.cpp, jchan.cpp and suprnova.cpp)
- National Semiconductor INS8250 UART: Added hack to reset transmitter when baud rate is changed. This is needed to make the (MESS) VT102 printer loopback test pass because ins8250_uart_device does not fully emulate the baud rate generator as the independent block it really is, but relies on the all-purpose, somewhat faulty device_serial_interface implementation.
- PCI bus: De-staticize callbacks and remove both device parameters (machine\lpci.cpp)
- Rockwell 10937 video: Cleanup
- RS232 Port: Moved devcb resolution to device_resolve_objects. Added V.24 cross reference. Added speed indicator to modem control and speed select output. Added DEC 12-15336-00 RS232 loopback connector type (required for (MESS) VT102 modem control self-test).
- SCN2674 Video
  . Use same character width for text and graphics modes. This change has been made partly to bring the implementation in line with other character-based video devices. It is also consistent with the documented ability of the SCN2674 to combine text and graphics modes on the same screen, which rules out bitmap resolution changes.
  . Massive register/command processing/logging cleanup
- Sega Custom
  . Added xhout and xvout register callbacks (video\segaic24.cpp), and hooked them up to Model 2 driver, fixing 3D viewport positions.
  . Internalized communication latches for sega_315_5195. 315-5195 mapper has same clock as CPU (segaorun.cpp, segas16b.cpp and segas18.cpp)
- Taito Custom
  . C-Chip
    . Use dumped C-Chip for Bonze Adventure, Rainbow Islands, Superman and Volfied and removed simulation.
    . Bonze Adventure: This most likely fixes the 1st level of Bonze Adventure, if you go into the secret hole and die in the cave, you restart in a totally black area and you can't do anything. And when you die in the 3rd level, an error message popped up and you was unable to do anything (had to restart the game) (ID 00205). This also fixed the 3rd level of Bonze Adventure, if you die, the game hangs because the restart level is wrong (ID 00377).
    . Mega Blast: Correct C-Chip clock
    . Operation Wolf: Measured C-Chip clock on working PCB (Taito custom C-Chip marked 'TC0030CMD, with sticker 'B20-18'. Clock input 12.00MHz on pin 20)
    . Rainbow Islands: Simulation isn't yet removed because Rainbow Islands Extra still needs it (Haze is checking if he can make a temporary ROM until it is so that we can clean it up in the meantime).
    . Rainbow Islands - Extra Version: Use a handcrafted C-Chip rom for Rainbow Islands Extra, pending a real dump, allows removal of simulation code and general cleanups. Also made Rainbow Islands Extra a parent, since it has it's own game code, own C-Chip and is generally considered a semi-sequel rather than a bugfix / revision of the original game. Best I can tell behavior matches the differences between original and extra that were present in the simulation at least, but obviously the real chip could be hiding more secrets.
    . Superman and Volfied: Made the 68k and uPD7810 use different banked windows into the RAM, this seems to prevent the fighting I was seeing, and also Superman suggests that it might be correct, as it puts response values in a bank for the 68k but then changes the window so the 68k can't see them. Needs further testing tho (other C-Chip dumps might tell us more later). Removed debug structure.
    . Volfied: Interrupt source still needs to be verified, but I've tested this to the end and it works fine with the real dump.
- TMS9927 video: Configure device using character clock rather than dot clock

- artmagic.cpp: Replaced NVRAM with parallel EEPROM and improved ADPCM banking. This fixed new NVRAM will cause a blasted sound on Get Ready screen at the beginning of Cheese Chase (ID 06917).
- asuka.cpp: Fixed clock speeds & misc updates. Both Galmedes & U.N. Defense Force: Earth Joker are chip swaps for Asuka & Asuka so use the Asuka machine config. Note that both games don't use the OKI MSM5205, but it's still on the PCB.
- crospang.cpp: Fixed clock speeds based on OSC & PCB info. Note: 68000P10 is a 10MHz part, so it's not going to be overclocked to 14.318MHz. All PCBs on this platform have only a single 14.31818MHz OSC so the Oki clock is either ~1.7MHz (OSC/8) or ~.89MHz (OSC/16).
- ddragon.cpp: Replaced HD6309 CPU1 with HD6309E
- dec8.cpp: Use input_merger for Gondomania and Garyo Retsuden. Acknowledge NMI another way for The Real Ghostbusters.

    . Eliminated vestigial member that was behind machine().first_screen() (emu\machine.cpp)
  . Get rid of the last set_indexed_value in drivers/devices, this ends up a bit ugly to maintain backwards compatibility with layouts/web UI (emu\output.h)
  . Fixed issue causing drivers using netlists to fail on the Emscripten target (netlist\plib\pdynlib.cpp)
  . Disable multithreading on the Emscripten target as it is not currently supported. Fixes e.g. drivers using discrete audio components (scripts\src\main.lua and osd\osdsync.cpp).
  . Removed stray address maps on spaces that don't exist (drivers\twincobr.cpp and (MESS) drivers). Cleanup address map remnants (de_2.cpp, s11c.cpp, segaybd.cpp and techno.cpp).
  . Added missing override (sound\coreaudio_sound.cpp and sound\pa_sound.cpp)
  . Apply same flags when building with SOURCES= as when building normally (scripts\build\makedep.py). This fixes the issue which prompted "model1: clear up some memory issues with very recent gcc (nw)" (which only occurred in a SOURCES= build).
  . Use more constexpr and literal classes in UML to give compiler more optimisation opportunities (cpu\drcfe.cpp and uml.cpp)
  . Reduced scope of stuff with different definitions across CPUs (cpu\e132xs\e132xs.h and sh\sh.h)
  . Prettier way of adding DRC framework on-demand (scripts\src\cpu.lua)
  . Reduced use of naked pointers, using namespace and preprocessor macros in recompiling CPU cores.
  . Don't sleepcode (dasm_override in emu\didisasm.h) - for some reason this only upset GCC, not Clang.
- Debugger
  . Fixed extent of debug view of address-shifted memory spaces (debug\dvmemory.cpp)
  . Fixed output of wplist debug command and find command for address-shifted spaces (debug\debugcmd.cpp)
  . Fixed watchpoint view for address-shifted spaces (debug\dvwpoints.cpp)
  . Fixed masking of offset expressions in debug view of address-shifted spaces (debug\dvmemory.cpp)
