- Intel 4004 CPU: Cleaner boilerplate (mcs40\mcs40.h)
- Intel I486 CPU: Don't mask top 8 bits of sgdt for 486 too, fixes win32s (cpu\i386\i486ops.hxx)
- MCS-51 MCU: Consolidated internal address maps. Eemoved P0 from ROMless versions since it conflicts with external accesses on hardware.
- Motorola MC68000
  . Fixed carry flag clear in divs and divu instructions (m68000\m68k_in.cpp). Note: The HP9000/300 selftests hangs in (MESS) hp9k_3xx.cpp. The debugger shows the following code: move.l (a2)+, d0; move.l (a2)+, d1; move d6, ccr; divs.w d0,d1 and loop: bcs.s loop. Clearly this tests whether the carry flag is cleared - the Motorola Reference Manual says it's always cleared. However, in our implementation, it's not cleared on overflow. The divu instruction is always cleared, even on overflow.
  . Fixed pack instructions (m68000\m68k_in.cpp). Note: The following test code from the 'HP9000/300 series mainframe tests' fails: lea bytes, a0; pack -(a0),-(a1), #$FEDC; move.b (a1),d0; cmbi.b #$E,d0; loop: bne.s loop and bytes: 0x41 0x42. It looks like most of the pack instructions have the byte order wrong, but the pack dx,dy variant seems to have been fixed already.
- AD1848 16-bit SoundPort: Swapped the crystals so it's playing at 32Khz instead of 22.05. This fixed all sounds playing too fast in mtouchxl.cpp (ID 06983)
- CD Audio: Added missing header bytes to mode sense, fixes audio playing with common DOS CDROM drivers (machine\t10mmc.cpp).
- DCS2 Audio Denver: Updated DCS audio to get San Francisco Rush 2049 closer to working (audio\dcs.cpp)
- Sound Blaster 16: Implemented direct DAC mode successfully tested in Scream Tracker 2.2
- TMS5220 sound
  . Converted logging calls to logmacro.h standard
  . Renaming improperly capitalized pseudo-macros and removed pseudo-macros from lvalues. Reorganized savestate values into a sane, maintainable order. Removed the unused, deprecated time_to_ready and cycles_to_ready functions. Fixed the race condition bug with m_buffer_low and m_buffer_empty flags not being updated before setting the interrupt state. Fixed the issue where if no VSM is actually attached to the 5220, the chip will get stuck speaking silence forever if it gets a Speak VSM command. In reality (at least on the tms51xx and probably the same here) the pin reads as open bus/noise, but will eventually hit a stop frame by reading 4 ones in a row. Added/fixed debugger fences for read functions where they were missing, and a write function where it was unnecessary and caused issues when issuing manual writes from the debugger. Changed the types of the flag variables already used for boolean values to bool, and simplified comparisons with them; also renamed the ambiguous m_data_register variable to the more descriptive name of m_read_byte_register. Changed status_read such that reading the status register from the debugger returns a valid value instead of 0, but doesn't otherwise affect the emulation. Make it so the /READY(readyq) callback only changes state to ready after a write during speak external mode, if the write actually completed because there was room in the FIFO. If not, it polls the fifo state every 16 cycles until there is room, and only then asserts the readyq callback. Actually zero the FIFO during initialization and when speak external goes active. Replaced memset calls with std::fill.
- 3dfx Voodoo Graphics: Reinstate texture address masking. Fixes segmentation fault in War: The Final Assault.
- Floppy: Improved logging, removed status flag ST1.ND on missing IDAM/DAM and added HEAD_LOAD state, used as a spinup delay by some systems (machine\upd765.cpp).
- Intel 8275 CRTC: DMA refinements: Exclude FIFO characters from counting towards filling character buffer. Extended DMA up to one character past an "end of DMA" control code. Clean up code slightly.
- MC146818 RTC
  . Don't restart timer unnecessarily
  . Correct interrupt polarity. This change makes the MC146818/DS128x devices use the regular ASSERT_LINE/CLEAR_LINE protocol like almost all other devices, removing an unexpected surprise. The devices are fairly widely used, so I've tried to review all of those references and check if they're affected. A surprising number of systems appear to have the interrupt hooked up, but were not accounting for the inversion, so this change might possibly correct some behaviour. The behaviour of the following might change: calchase.cpp, hotstuff.cpp, mtouchxl.cpp, pcat_dyn.cpp, su2000.cpp, machine\pcshare.cpp, machine\sis85c496.cpp and bus\lpci\southbridge.cpp.
- MC6840 PTM: Fixed divide-by-8 mode. In divide-by-8 mode the value computed in compute_counter() is wrong because the function doesn't divide the clock before the calculation.

- dreamwld.cpp: Documented MCU and fixed MCU ROM region size
- exidy.cpp and victory.cpp: Full encapsulation of audio devices
- gaiden.cpp: Added undumped MCU to wildfang and stratof configuration and correct size of internal ROM region. Note: Regarding the MCU type: This was reported as "NEC D8749HC" back in 2001 by Yasuhiro Ogawa, but the location (unpopulated on Ninja Gaiden) is silkscreened "uPD8049" on the PCB.
- hornet.cpp
  . Added separate dipswitch settings for Gradius IV

  . Replaced machine().device with finders
  . Fixed ROM loading bug in The Empire Strikes Back
- stv.cpp: Removed tag lookup from machine\saturn.cpp
- taito_b.cpp: Identified TC0180VCU as source of interrupts and change these into callbacks. The interval between the two has been changed (no longer being an arbitrary multiple of the CPU clock), but the timing is still more or less guesswork.

- Trojan: Fixed DIP location numbering (ID 07020)
- Truco Clemente: Allow multiple coin insertions
- Video Poker: Clean up
- War Mission: Added new disk image (Game now playable). Note: Data after 0xd56b0 would not read consistently, however the game only appears to use the first 24 tracks (up to 0x48fff) as it loads once on startup, not during gameplay, and all tracks before that gave consistent reads. There is data after this point but it is likely leftovers from another game / whatever was on the disk before, so for our purposes this should be fine. Some bullets do seem to spawn from locations where there are no enemies, but I think this is just annoying game design. 2 player mode can be enabled in service mode for War Mission, it is disabled by default (settings are stored on the disk).
- Williams Multigame: Make game working again. Cleanups. Added address_map_bank_device for IO Bankswitching, machine_start/reset instead MCFG_MACHINE_START/RESET and save state. Fixed naming and crash.

  . ROMLOAD
    . Move the +1 to the proper place in the ROM BIOS macros (emu\romload.h and romentry.h) - that's been confusing people for far too long.
    . Added a valdiation check for ROMs with BIOS flag set that are unselectable, fix the things it uncovers.
    . Allow BIOS declaration before first ROM region
  . DEVICES
    . Improved validation and fixed formatting (emu\diexec.cpp and screen.cpp)
    . Eliminated customized MCFG_DEVICE_ADD macros (AT28C16, C352, DS1302, DS1386, DS2404, MC146818, MCD212, MSM5832, Timekeeper, WD1773, WPC_DMD, WPC_LAMP, WPC_OUT, WPC_PIC, WPC_SHIFT and YGV608)
    . Added customized MCFG_DEVICE_ADD macros (asuka.cpp, goldstar.cpp, hornet.cpp, ksys573.cpp, model1.cpp, model2.cpp, ninjaw.cpp, othunder.cpp, segahang.cpp, segam1.cpp, segaorun.cpp, segas16a.cpp, segas16b.cpp, segas18.cpp, segas24.cpp, segaxbd.cpp, segaybd.cpp, stfight.cpp, system16.cpp, taito_f2.cpp, taito_z.cpp, vicdual.cpp, warriorb.cpp, video\sega16sp.h, segaic16.h, segaic16_road.h, segaic24.h, stfight_dev.h and tc0110pcr.h)
    . Use device finder for deco_mlc.cpp, dogfgt.cpp, drw80pkr.cpp, gaelco3d.cpp, magmax.cpp, mediagx.cpp, mpu4.cpp, othello.cpp, snk6502.cpp, starwars.cpp and trackfld.cpp
    . Miscellaneous machine().device and MCFG cleanups (cclimber.cpp, crystal.cpp, galaga.cpp (Battles), gaplus.cpp and video\tia.cpp)
    . Removed machine().device lookups (calcune.cpp, konamigx.cpp, megatech.cpp, midyunit.cpp, model2.cpp, multigam.cpp, munchmo.cpp, segac2.cpp, segas18.cpp, video\315_5313.cpp and video\k054338.cpp)
    . Removed machine().device usage from beathead, by17, by35, cave, coolpool, cps3, dfruit, dkong, dvk_kcgd, foodf, gridlee, hyprolyb, irobot, itech32, jedi, jpmimpct, jpmmps, jpms80, kaneko16, mario, mcr, mcr3, mystston, phoenix, pkscram, pleiads, polepos, redalert, scramble, segag80r, segag80v, segas24, sis85c496, slapstic, snk6502, starwars, stv, subsino2, toaplan1, trackfld, tx1 and audio\segasnd.cpp. src/mame/audio is now clean of machine().device.
    . Replaced machine().device with subdevice for NVRAM installation (esripsys.cpp, hitpoker.cpp, magtouch.cpp, meritm.cpp, namcos2.cpp, pcat_dyn.cpp, pcat_nit.cpp, s7.cpp, segas24.cpp, tmnt.cpp, triplhnt.cpp, ttchamp.cpp, twin16.cpp, upscope.cpp, videopkr.cpp and zn.cpp)
    . Misc device finder / private members (jongkyo.cpp, namcos86.cpp, nsmpoker.cpp, pachifev.cpp, pinkiri8.cpp and system1.cpp)
  . MEMORY SYSTEM
    . Reduced code duplication and added support for device finders in more places in memory maps (emu\addrmap.h)
    . Make address map config look like Next-gen
    . Added streamline templates in addrmap.h. Get rid of overloads on read/write member names - this will become even more important in the near future.
    . Lift some stuff needed by devcb3 out of address map entry
    . Get rid of some overloaded names - a lot of these will become unnecessary after new memory and devcb are ready.
  . Prevent segfault at stop and when selecting device from menu (emu\dinetwork.cpp and osd\osdnet.cpp)
  . Fixed connecting to existing socket (osd\modules\file\winptty.cpp)
  . Make it possible to set screen update functions without macros without syntax that looks absolutely terrible (emu\screen.h) - examples will come with DEVCB3.
  . PLUGINS
    . Added discord presence plugin. Use domain sockets and pipes.
    . Use explicit integer sizes rather than "native" types (plugins\cheatfind\init.lua)
  . VGM player: Added Stop, Pause, Play, Restart and Loop controls. Added rudimentary layout using default font symbols to provide clickable buttons for the new media controls recently added. The cursor doesn't seem to show up, but I'm sure one of the layout wizards can quickly remedy that. Added LEDs.
- SDLMAME: GetCurrentProcessId is valid on lib\osdlib_uwp.cpp
- Compiling
  . Added asserts to detect tag being set after object resolution and resolved multiple times
  . Added AppVeyor build configuration (appveyor.yml)
  . Fixed SUBTARGET=virtual (cripts\target\mame\virtual.lua)
  . Made m68000 makefile respect the VERBOSE build optio (m68000\makefile)
  . Removed emupal.h from emu.h
  . Enable building on RISCV64
- Debugger
  . Added command for go_exception
  . Make save/load support virtual memory. This makes these commands useful and consistent with dump in a virtual memory environment. One minor issue is what to do with save for an unmapped memory address: the approach taken here is to write the space.unmap() value, which seems the least harmful. On load, unmapped addresses are not written to, meaning that save/load with a constant address map work as expected.
