- CPU
  . Hitachi HD6301 und HD63701: Splitted "HD6301" and "HD63701" devices into several different types (functionally identical now, but won't be compatible once accuracy improves). SLP is no longer disassembled as "illegal" on the HD6301. Tentatively start to support the extra ports of the HD6301X/HD6301Y. Implement more HD6301X weirdness. Added preliminary HD6301X internal register map. Added second timer output comparator and associated status register to the HD6301X and HD6301Y.
  . Hitachi SH-3/4: Removed unnecessary SuperH 3/4 timers restarts (cpu\sh\sh4tmu.cpp)
  . Intel P8098: Fixed I8096 JNH/JH opcode according to manual (mcs96\mcs96ops.lst)
  . Motorola MC6801
    . Attempt at cleaning up internal registers. Splitted the all-in-one m6801_io_r and m6801_io_w handlers into separate handlers for each register. Use m() instead of rw() to map these for now. Make all port direction registers write-only.
    . Fixed a bug that deadlocked the emulation during WAI/SLP if a timed event had already occurred.
    . Added DDRs as mask for port output callbacks. Added second timer output comparator.
  . Motorola MC6803: Added Motorola MC6803E and Hitachi HD6303X types. Delete the "unused" NOP mapping from $0020 to $007F in the MC6803 internal map (datasheets make clear that external accesses can be made here).
  . NEC uPD7801/7807/7810/78C11: Divide internal clock by 2 or 3
  . NEC uPD7810
    . Make internal timers run at former speed and A/D timer at former rate relative to CPU states

Inhibit clearing of interrupt flag upon acknowledgment when another interrupt with the same priority is also enabled. Added a crude start bit check to asynchronous serial mode.
    . Fixed random hanging in Gun Master and probably other games with uPD7810 sound by not syncing on each shift (drivers\metro.cpp). Fixed loss of sound in games with uPD7810s other than Daitoride, Pururun and Gun Master (drivers\metro.cpp).
    . Added configuration option to disable port pullups for output
    . Refresh PA/PB/PC/PF outputs upon mode change
  . TLCS-90 (Toshiba TMP90840/41/PH44/TMP91640)

    . Added constructor which accepts a format string for object names
    . Started work on logic_input8 which provides 8 logic outputs
    . Added sampled output format to netlist\prg\nlwav.cpp. Using this output format nlwav will pick point samples at regular intervals from log files. This can be used to e.g. calculate RGB output levels with netlist. Use netlist to calculate RGB values for Turkey Shoot. This example shows how the netlist tools can be used to derive RGB tables from a schematic. All steps are given in netlist\examples\turkey_shoot.cpp. Fixed inductor calculation. Updated turkey shoot example to skip start-up swinging of L1/C60 LC circuit. Recording now starts at 1ms.
  . Floppy: Added a MON callback so that drives, which are unselected early, do not spin forever (machine\wd_fdc.cpp).
  . I2C Memory
    . Latch the upper address bits from the I2C device ID after receiving the lower 8 bits of the address, implemented 2-wire softwarereset for I2C, stop nack from lowering sda and removed redundant state from I2C page write (machine\i2cmem.cpp).
    . Added support for the address high byte to i2cmem for devices greater than 4096 bytes
  . Namco C355 (Sprites): Converted sprite drawing behavior related to template bitmap. Fixed overwritten shadowed pixel. Support bitmap_rgb32. Implemented m_screenbitmap clearing. Added renderable bitmap with sprite effects to m_screenbitmap.

  . Improved 2nd Generation Williams hardware color display (Inferno, Joust 2, Mystic Marathon and Turkey Shoot). Changed color levels for williams2 hardware to better color display. Output levels are computed in netlist. These levels are aligned to LTspice modelling I did. Also improved the modelling to do what the actual hardware for Mystic Marathon did: Color decoding depends on W13..W11. These are actually flip screen versions of V13..V11. Fixed treatment on Bit0 although not used by the game code. Added R,G,B gain and offset sliders for the williams2 hardware. MAME only supports one setting for all channels. This is not good enough to come close to video recordings found on youtube. Minor changes to nltool to better measure time taken to run a simulation.
  . Improved color processing. Offsets now cut off before gain is applied. This is how the "cutoff" monitor controls on arcade monitors worked. Adjusted R,G,B gains and offsets.
  . Use floating point literals to stop MSVC warning C4305 (video\williams.cpp)

- MAME
  . VIDEO RENDERING SYSTEM
    . Added a missing break function (emu\screen.cpp)
    . Replaced SET_TILE_INFO_MEMBER macro with tileinfo.set helper. That macro has contributed nothing but obfuscation since we moved to C++ (emu\tilemap.h).
  . DEVICE: sSimplified handler for a few devices (video\bufsprite.h, ramdac.cpp, tms9927.cpp and zeus2.cpp)
  . LUA engine: Added save state to/from binary string buffer
  . UI: Added an About menu option to display the contents of COPYING in order to be more license-compliant (frontend\mame\ui\about.cpp)
  . Removed winpcap and cleaned up network module selection. The pcap.h header itself has the problematic original BSD license, including the obnoxious advertising clause. Using tap/tun networking on Windows provides a much better experience, so the extra setup is worth it. This patch also allows you to enable pcap on platforms where it's disabled by default with USE_PCAP=1 if you really want to use it.
  . Simplified video handlers (cpu\h6280\h6280.cpp, video\ef9369.cpp, hd61830.cpp, huc6260.cpp, jangou_blitter.cpp, mb90082.cpp, mb_vcu.cpp, ppu2c0x.cpp and snes_ppu.cpp)
  . Simplified sound handlers (sound\ad1848.cpp, astrocde.cpp, c6280.cpp, cdp1863.cpp, cdp1869.cpp, dave.cpp, digitalk.cpp, es5506.cpp, es8712.cpp, huc6230.cpp, iremga20.cpp, k005289.cpp, k007232.cpp, k056800.cpp, mea8000.cpp, mos6560.cpp, msm5205.cpp, msm5232.cpp, multipcm.cpp, n63701x.cpp, namco.cpp, okim9810.cpp, qs1000.cpp, qsoundhle.cpp, s14001a.cpp, segapcm.cpp, snkwave.cpp, sp0250.cpp, st0016.cpp, tiaintf.cpp, tms5110.cpp, upd1771.cpp, upd7752.cpp, upd934g.cpp and ymz770.cpp)
  . Simplified driver handlers (drivers\24cdjuke.cpp, 2mindril.cpp, 30test.cpp, 4roses.cpp, 5clown.cpp, ace.cpp, acefruit.cpp, aces1.cpp, airraid.cpp, akkaarrh.cpp, albazc.cpp, albazg.cpp, alinvade.cpp, allied.cpp, cclimber.cpp and kyugo.cpp)
  . Eliminated now-unnecessary bus_r and bus_w handlers (drivers\asteroid.cpp, astrocde.cpp, dkong.cpp and mario.cpp)
  . Cleanup: Added doxygen comments for bit manipulation functions. Added an overload of BIT that works like the AArch64 UBFX instruction. Kill off some of the silly concatenating overloads for emu_file::open. Make searchpath acually useful for devices.
  . Restored lost message about invalid BIOS (emu\romload.cpp)
  . Fixed Viewpoint entry in plugins\hiscore\hiscore.dat (ID 07592)
  . Roll back no longer needed /ZI workaround (scripts\src\tools.lua). It has been fixed as of Visual Studio 2019 16.5.
  . Removed tools\src2html.cpp
- VGM player: Added a visualizer. Provides a waterfall, spectrograph and VU view.
- Compiling: Updated more stuff in top-level makefile
- Debugger: Fixed two cases where debugger can crash MAME ("cheatlist" command before "cheatinit", long strings after "help") (debug/debugcmd.cpp and debughlp.cpp)
