- 8085A CPU
  . Code readability (just whitespace/comments cleanup here). Moved opcode macros to main file, will convert these to functions. Moved single-use opcodes to execute function. Lowercase/Renamed some functions.
  . Make cputype an enum, change flags and stuff to constexpr. Shorthand variable types. Changed opcode macros to functions. Cleanup. Added opcode space.
- ARM7/9 CPU
  . Added rudimentary instruction prefetch buffer. Fixes (MESS) GBA NES Classics games.
  . Added 32- and 64-bit population count utilities. Only used in ARM7 core for now. Requires -msse4.2 or -mpopcnt to use CPU feature on x86 and -mpopcntb to use CPU feature on POWER (cpu\arm7\arm7ops.cpp and osd\eminline.h).
  . Fixed ARM7_BE and ARM7 MMU regressions
  . Derived IGS036 type in ARM7/9 core, because it seems like MMU could be different and there are probably other internal devices.
  . Fixed (?) BLX (LO) thumb opcode in ARM7/9 core, was storing a return address that skipped the following opcode. There might still be ARM9 issues.
  . LDR/LDRM switch to Thumb mode on ARMv5T (cpu\arm7\arm7ops.cpp). Added ARM v5/9 check. Handle DP-commands ROR  case where Rs=32/64, removed few outdated comments.

  . Flesh out ARM946ES, added movable DTCM and ITCM support.
- CDP1802 CPU: Added WAIT/CLEAR input lines
- HuC6280 CPU: Fixed brk logerror
- Hyperstone CPUs
  . Some optimization (cpu\e132xs\e132xs.cpp), Elfin (dgPIX Entertainment Inc. 1999) benches roughly faster.
  . Removed unnecessary full reinit of regs_decode struct (cpu\e132xs\e132xs.cpp)
  . Reworked all opcodes, now considerably faster.
  . Templated all opcodes to reduce code duplication and fixed a few oversights. Fixed ldxx2 local,local case.
  . Added template check, index move, mask and sum handlers. sum Rd,C,const was incorrectly using the whole SR rather than just the carry value; sums with local register as destination was not burning cycles; negs doesn't need explicit guard against trapping when source is SR as carry flag alone can never cause an overflow. Template register-register mov and correct trap behaviour privilege trap should prevent user state code from writing high global registers; also change DEBUG_PRINTF to standard logmacro.h stuff.
  . Simplified set opcode, removed some needless use of set_global_register to get some speed back.
- M6800 CPU: Reinstated registration of SR for debug expressions (cpu\m68000\m68kcpu.cpp)
- M68010/68020/68030 CPUs: Added support for bus error stack frames formats. This fixes common CPU type detection routine: http://www.easy68k.com/EASy68Kforum/viewtopic.php?p=1105#p1105  (cpu\m68000\m68kcpu.h).
- MCS-48 CPU: The MCS-48 core needs to be re-written so it works at S-cycle level (if not clock cycle level), but for now I've worked around this case in the least intrusive way possible.
- MIPS CPUs
  . Minor MIPS DRC fastram optimization and simplification (cpu\mips\mips3drc.cpp)
  . Cleanup TX4925 CPU implementation
- PowerPC 4xx/6xx CPUs: Attempt at fixing PPC DRC scheduling (cpu\powerpc\ppcdrc.cpp). This fixed black screen on launch in Scud Race Twin (ID 06615).
- SH-3/4 CPU
  . Added some SH3/4 recompiler changes that got lost at some point. It fixes an issue where 'Mushihime-Sama Futari Black Label' sound would cut out if left in attract mode on first boot due to timer irq 0 being missed and then never refiring due to the way the DRC code blocks work.
  . Mark DRC cache dirty on reset
- TLCS-90 CPU: First step towards modernization of internal peripherals (cpu\tlcs90\tlcs90.cpp)
- Z80 CPU: Implemented Z80 HALT output and clear HALT condition during reset. Wakeup (MESS) Ritam 'Monty Plays Scrabble' and 'Master Monty' from HALT instruction using reset.
- Williams ADPCM Sound Board: Lower the DAC volume of the williams_adpcm_sound_device (audio\williams.cpp). This fixed missing music in Mortal Kombat (ID 06694).

- 8155 RIOT: Substantially rewrote timer emulation. Modernized logging. Abandon "RIOT" name properly belonging to MOS 6532. Provided separate device type for 8156. Regression fix for Golden Arrow.
- ADC0844 and ADC0848 A/D Converter
  . Added ADC0844 A/D Converter for input to mcr3.cpp (maxrpm), mcr68.cpp (spyhunt2), micro3d.cpp, midvunit.cpp and midyunit.cpp (term2)
  . Support ADC0848 variant, some adjustments to differential mode. Added ADC0848 to midxunit.cpp (revx).

  . Added DECO CRTC (12MHz/2) and screen raw params for bogeyman.cpp, chanbara.cpp, dec0.cpp, dec8.cpp, firetrap.cpp and ssozumo.cpp
- DS12885 RTC: Fixed DS128X/DS1288X main frequency divider. The output frequency must be fixed to 1HZ with these devices. In the MC146818, DV2-DV0 were used to select the input frequency to provide a proper time base. Since the DS12885/87 and DS1685/87 use only the 32.768kHz crystal these 3 bits are used to turn the oscillator on or off and to reset the countdown chain. There are not used anymore to select the main clock divider value.
- EEPROM
  . Added serial EEPROM using new DO write callback to (MESS) TTI SBC (machine\eepromser.cpp). Added reference info for X2444 commands.
  . Added device emulating 28F010 Flash memory and family (not compatible with JEDEC Flash protocol). Converted (MESS) Interpro to use this device.
- Floppy

- MC6845 CRT: Minor transparent update refactoring
- RS232: Changed 9615 baud configurations to the nominal 9600 baud now that Z80SIO is more tolerant
- uPD4701 counter: Better handling of uPD4701 control lines
- V9938/9958 video: Converted to use RGB32 bitmaps. Palette has been retained mostly for the sake of the palette viewer, and now reflects the actual programmed values, rather than being a fixed RRRGGGBBB encoding plus a hacky mess for the V9958's YJK colors. V9938-on-V9938 transparent overlay is fixed for meritm.cpp (was broken a few releases ago).
- Voodoo GFX
  . Use SSE routines for texture perspective correction

- Z80 SCC: General cleanup and backport of Z80 SIO improvements (machine\z80scc.cpp)
- Z80 SIO
  . Moved object finder resolution before device_start (emu\device.cpp and machine.cpp). This fixed Z80SIO not safe with attached RS232 port. MAME can crash if a device sets the initial state of the input lines for a z80sio_device at device_start time.
  . Made async receive behave more like real device. Check that start bit persists for half a clock interval. Sample data bits mid-interval. Handle invalid stop bit as described in Zilog manual. Check parity and latch overrun and parity errors. This fixes the issues with corrupt characters being typed on the Kaypro. Synchronous modes are still broken. The channels are still using device_serial_interface to transmit frames, but receiving is handled entirely in the device class itself. Overruns still aren't handled properly.
  . Better handling of Rx FIFO and interrupts in async mode. Framing error should always generate interrupt in interrupt-on-first mode.
  . Moved dlair.cpp and proconn.cpp driver from z80dart.h to z80sio.h
  . First stab at WRDY emulation. Some logging improvements. Use arays for callbacks.
  . Don't use device_serial_interface for transmit - it can't support sync modes, on-the-fly register updates, and other weirdness. Better modelling of 1-deep transmit queue. Better RTS/CTS behaviour. Completely overhauled interrupt logic - vectors should be correct for most async modes. Implemented different auto-reset receive errors in MPSC vs SIO. Implemented SDLC transmission including bit stuffing, transmit CRC, abort, and underrun/end-of-message behaviour. Added an SDLC consumer device that logs SNA frame headers and data.
  . Generalise synchronous transmission to other modes, re-implement break detection.
  . Implemented enough of synchronous receive mode to pass (MESS) Univac UTS-20 channel A loopback test. Treat disabling transmitter as satisfying a transmit interrupt. Disabled automatic CRC transmission in monosync mode. Clear receive errors on channel reset. Fixed reporting receive errors.
- amusco.cpp: Improved colors. Removed VRAM placeholder, allocate it in video_start.
- aristmk5.cpp
  . Added BIOS / USA Set Chip v4.04.08

  . Changed RF5C400 clock to match board notes in driver. Added 8Mb of dummy ram to the RF5C400 and adjusted the banking so that sounds play correctly. Fixed RF5C400 sound regression. This fixes the dog whistling and other issues in the beatmania IIDX games.
  . Improved LED font from available reference sources. Mapped lamps and dipswitches. Added basic internal artwork.
  . Changed security card padding from 0x00 to 0xff, beatmania IIDX 4th & 5th have now been dumped and the serial numbers scrubbed.
- vectrex.cpp: Quick and dirty regression fix
- zn.cpp: Mostly switched to configured banking. NBA Jam Extreme banking still to update. Very preliminary work on supporting save state. Will need more work in various devices. Use optional_memory_bank.

- MAME
  . UI
    . Fixed can't change into directories that have a "." prefix in their name (ui\filesel.cpp and posixdir.cpp) (ID 06785)
    . Fixed off-by-one crash (ui\selsoft.cpp)
  . MEMORY SYSTEM
    . API change (emu\emumem.cpp): * direct_read_data is now a template which takes the address bus shift as a parameter. * address_space::direct() is now a template method that takes the shift as a parameter and returns a pointer instead of a reference. * The address to give to {read|write}_* on address_space or direct_read_data is now the address one wants to access. Longer explanation: Up until now, the {read|write}_* methods required the caller to give the byte offset instead of the actual address. That's the same on byte-addressing CPUs, e.g. the ones everyone knows, but it's different on the word/long/quad addressing ones (TMS, Sharc, etc...) or the bit-addressing one (TMS340x0). Changing that required templatizing the direct access interface on the bus addressing granularity, historically called address bus shift. Also, since everybody was taking the address of the reference returned by direct(), and structurally didn't have much choice in the matter, it got changed to return a pointer directly. Longest historical explanation: In a cpu core, the hottest memory access, by far, is the opcode fetching. It's also an access with very good locality (doesn't move much, tends to stay in the same rom/ram zone even when jumping around, tends not to hit handlers), which makes efficient caching worthwhile (as in, 30-50% faster core iirc on something like the 6502, but that was 20 years ago and a number of things changed since then). In fact, opcode fetching was, in the distant past, just an array lookup indexed by pc on an offset pointer, which was updated on branches. It didn't stay that way because more elaborate access is often needed (handlers, banking with instructions crossing a bank...) but it still ends up with a frontend of "if the address is still in the current range read from pointer+address otherwise do the slowpath", e.g. two usually correctly predicted branches plus the read most of the time. Then the >8 bits cpus arrived. That was ok, it just required to do the add to a u8 *, then convert to a u16/u32 * and do the read. At the asm level, it was all identical except for the final read, and read_byte/word/long being separate there was no test (and associated overhead) added in the path. Then the word-addressing CPUs arrived with, iirc, the tms cpus used in atari games. They require, to read from the pointer, to shift the address, either explicitely, or implicitely through indexing a u16 *. There were three possibilities: 1. Create a new read_* method for each size and granularity. That amounts to a lot of copy/paste in the end, and functions with identical prototypes so the compiler can't detect you're using the wrong one. 2. Put a variable shift in the read path. That was too expensive especially since the most critical cpus are byte-addressing (68000 at the time was the key). Having bit-adressing cpus which means the shift can either be right or left depending on the variable makes things even worse. 3. Require the caller to do the shift himself when needed. The last solution was chosen, and starting that day the address was a byte offset and not the real address. Which is, actually, quite surprising when writing a new cpu core or, worse, when using the read/write methods from the driver code. But since then, C++ happened. And, in particular, templates with non-type parameters. Suddendly, solution 1 can be done without the copy/paste and with different types allowing to detect (at runtime, but systematically and at startup) if you got it wrong, while still generating optimal code. So it was time to switch to that solution and makes the address parameter sane again. Especially since it makes mucking in the rest of the memory subsystem code a lot more understandable.
      . Constexpr implies inline, generalise iabs, work around lack of C++14 constexpr in VS2015 (emu\emucore.h and emumem.cpp/h).
    . Replaced space.machine() with machine() (emu\emumem.cpp)
    . Eliminated remaining uses of address_space::machine() outside of emumem (debug\debugbuf.cpp, debugcmd.cpp and machine\seibucop\seibucop_cmd.hxx)
    . Removed machine member of address_space (emu\emumem.cpp)
  . DEVICES
    . Fixed -listdevices misplacement of subdevices in some configurations (mame\clifront.cpp)
    . Moderate overhaul of device_rom_interface: Allow endianness and data/address width to be altered during configuration. Raise memory_space_config from private to protected so it can be overridden. Make entire interface optional (as needed by one device to be added soon). Use interface_post_load instead of explicitly registered delegate. Only call rom_bank_updated when bank actually changes. Removed prototypes for nonexistent functions (emu\dirom.cpp). Documentation update (docs\source\techspecs\device_rom_interface.rst).
    . Replaced some space.device() calls (drivers\namcos11.cpp, namcos22.cpp, namcos23.cpp, naomi.cpp, rmhaihai.cpp, witch.cpp, x1.cpp, x68k.cpp, xexex.cpp, xmen.cpp, xyonix.cpp, yunsung8.cpp and zn.cpp)
    . Eliminated device pointer conversion from device_interface (emu\device.h)
  . Added rewind feature and RAM savestates
    . How RAM states work: Implemented using util::vectorstream. Instead of dumping m_save.m_entry_list to file, it writes them as binary to vectorstream. Compression is not used, as it would slow down the process. The header is written as usual, also in binary. When a state is loaded, the savestate data gets binary-read from vectorstream. How rewind works: Rewind is optional, it can be turned off through MAME GUI while not running. Rewind capacity is available there too. Rewind step hotkey is available from the standard hotkey menu. In the debugger you have the "rewind" command ("rw" shortcut) that works the same as the hotkey. Every time you advance a frame (pause step), rewinder captures a RAM savestate of the frame you were at. It does the same when you do step into/over/out in the debugger. Every time it captures a new state (and when you unpause), it marks as invalid all its states that go after the current machine time, because input might change, so they are not relevant anymore. It keeps their buffers allocated though, for future use. When rewinder runs out of allowed amount of savestates it can have, it invalidates the first state in the list and tosses its unique_ptr to the end of the list, then it uses its buffer to capture a new state. When you hit the rewind step key, or use "rewind" command in the debugger, it loads a state that is immediately before the current machine time. Invalid states between valid ones are not allowed to appear, as that breaks rewinder integrity and causes problems. Rewinder keeps its own set of ram states as a vector of unique_ptr's. All rewinder operations and errors get reported using machine().popmessage().
    . icount was missing from the savestates. When you load a state, icount (*icountptr) would remain whatever it was before loading, messing with the remaining cycles and with the amount of code executed per run() call. This introduced non-determinism and badly influenced usage of savestates while debugging. machine().time() would also return wrong values after that, since it adds remaining cycles (emu\diexec.cpp).
  . Get rid of legacy BITSWAP* (BITSWAP8(_) -> bitswap<8>(_)) (emu\emucore.h)
  . Stop save and load logging timers unless VERBOSE is set (emu\schedule.cpp)
  . Changed misleading parameter name (emu\softlist_dev.cpp)
  . Validity: Prevent insane recursion when multiple slot devices have the same tag (emu\validity.cpp)
  . PLUGINS
    . Fixed sentence building by concatenation, and at the same time collapse two translatable strings to one (plugins\cheatfind\init.lua).
    . Added a message when the console plugin is not found, rather than crash. In absence of the console plugin, the option entry was not found in m_plugins, making the set_value() crash when deferencing the result of get_entry(). Instead, an error message is logged telling the plugin is not found. Trigger a fatal error when console was asked but the console plugin not found.
    . Updated hiscore.dat. Removed duplicate sets, debug print and merged identical entries.
    . Fixed crlf issue (plugins\data\load_dat.lua)
  . 3rdparty: Updated GENie, BGFX and BX. Added BIMG since it is separated now, updated all shader binaries and MAME part of code to support new interfaces.
  . Multi-Language: Updated Brazilian Portuguese, French and Italian translations. Note: All translation updated to follow GNOME Translation Rules for Brazilian Portuguese, this are the same rules for other Linux Distributions, Manuals, etc. Now we can avoid translation conflicts (http://br.gnome.org/GNOMEBR/ErrosFrequentes and http://br.gnome.org/GNOMEBR/GuiaDoTradutor).
- Compiling
  . Start replacing auto_alloc_* with smart pointers, get rid of reference constants in the debugger in favour of capturing the value in the bind/lambda (cpu\i386\i386.cpp, debug\debugcmd.cpp/h, debugcpu.cpp/h, express.cpp/h, mame\cheat.cpp/h, drivers\amusco.cpp, coolridr.cpp, includes\cave.h, wecleman.h, video\cave.cpp and wecleman.cpp).
  . Allow compiler a little more optimisation leeway in x86 count_leading_* (emu\validity.cpp, osd\eigccx86.h and eivc.h)
- Debugger
  . Disassemblers are now independant classes. Not only the code is cleaner, but unidasm has access to all the CPU cores again. The interface to the disassembly method has changed from byte buffers to objects that give a result to read methods. This also adds support for lfsr and/or paged PCs. Fixed building with Visual Studio 2017 & Clang 5.0.0 (also tested with GCC 7.2.0).
  . Reset m_dasm on source switch (debug\debugvw.h and dvdisasm.cpp/h)
  . Added nicer autoscrolling (debug\dvdisasm.cpp)
  . Fixed watchpoint hit message for address-shifted processors (debug\debugcpu.cpp). Fixed memory window (debug\dvmemory.cpp).
  . Changed back to uppercase hex for util::stream_format (debug\debugbuf.cpp)
  . Set REG_BEAMX/BEAMY/FRAME to 0 on invalid eg. screenless (debug\dvstate.cpp)
