- CPU
  . Analog Devices ADSP21062 SHARC: Added compute_fcopysign
  . Intel I386
    . Added more msrs releted to SMM to Athlon XP (i386\cpuidmsrs.hxx and i386.cpp/h). Athlon XP now supports system management mode.
    . Improved splitting of unaligned accesses (excluding program fetches). This entails a major code reorganization just to keep the scale of it all halfway sane.
    . Fixed enter insn (i386\i386op16.hxx and i386op32.hxx)
  . Intel I80186: Peripheral register refinements. Emulated strange but documented behavior of unaligned accesses and byte writes to internal peripheral registers. Use more official register mnemonics. Use official names for DMA registers.
  . Intel i960KB: Implemented logr and expr opcodes (cpu\i960\i960.cpp) for Power Sled
  . MC68340: Fixed interrupt vectoring
  . MIPS-I/III/IV
    . Preserve upper 32 bits for single-precision fp operations. While this behaviour is undefined according to the MIPS R4000 Microprocessor User's Manual, various factors point toward it most likely being correct, including: 1. The fact MIPS-I exposes 16x64-bit floating-point registers, but internally implements them as pairs of 32-bit registers (with only the even-numbered pairs being valid for arithmetic operations), making it somewhat likely MOV.S, like LWC1 and SWC1, can access either half. 2. Explicit mention in IDT documentation and "See MIPS Run", i.e. "The odd-numbered registers can be accessed by move and load/store instructions", and other commentary. 3. The presence of paired-single operations in later MIPS32/64 specifications, which operate on independent single-precision values stored in each of the lower and upper halves of a single floating-point register.
    . Use sequence generator for random tlb indices so that DRC and non-DRC code sequences match
    . Fixed tlbmiss in delay slot (mips\mips3drc.cpp)
    . MIPS R4000
      . Relaxed address validity checks in 32-bit mode allowing simplified base + offset computation. Removed inaccurate/partial cycle counting. Slight adjustment to ll/sc logic. Corrected address alignment exception type. Changed LL/SC behaviour to not use a write tap. Possibly incorrect behaviour, but IRIX 6.5 installer doesn't hang anymore on miniroot creation. Added bus error functionality.
      . SGI IDE fixes. Corrects some TLB diagnostic errors (remaining ones require implementing a data cache) and the FPU "underflow" test (really an unimplemented instruction exception, not an underflow) by checking for denormalized or quiet NaN operands for all floating point arithmetic instructions.
  . Mitsubishi M37710S4: Replaced I/O space with callbacks
  . Motorola M6801: Fixed bug where irq is never triggered
  . Motorola MC680x0
    . Converted code generator to python. Stop using spec_proc. Merged table and opcode body together. Changed method pointers to state IDs in the big tables.
    . SCC68070 fixes: Added several MC68000 opcodes that were inadvertently unsupported. Changed behavior of CLR with memory operand to match MC68010 and later (datasheet makes it clear that the extra read is not performed). Clarify that SCC68070 RTE is more like MC68010 than MC68000. Re-added a few more inadvertently illegalized opcodes (CHK, DIVS, DIVU).
    . M68000: Read the initial SP and PC from memory after rather than during machine reset time. This removes the need for many drivers to reset the CPU an extra time to load the correct vector.
    . Show M68K_SR. Renamed ISP to SSP for pre-68020 (m68000\m68kcpu.cpp). Fixed MOVEC formatting (m68000\m68kdasm.cpp).
    . Reverted the ATC calculation fix in MAME 0.209 (m68000\m68kmmu.h) which broke both Mac OS and HP-UX. Fixed the real MMU problem Domain/OS was having.
  . Motorola MC68705
    . Prevent registration of illegal debug states for nonexistent port latches/DDRs
    . Fixed prescaler update. Restored the proper behaviour of the timer (ID 07317).
  . RCA CDP1801/2: Fixed long branch instruction timing
  . Texas Instruments TMS57002 DASP: Simplified handlers. Fixed code styles and notes. Use shorter type values.
  . Zilog Z8002: Added register save state. Misc cleanup. Pile on some extra address spaces.
- DEVICE
  . 6821 PIA: Added port line write handlers
  . Atari ASIC65: Simplified handlers. Use shorter type values. Reduced unnecessary lines. Fixed debugger issues and spacing.
  . Atari Custom
    . atarigen.cpp: Simplified handlers. Reduced unnecessary lines. Fixed debugger issues, notes and spacings. Use shorter type values.
    . atarirle.cpp: Simplified handlers. Use shorter type values. Fixed spacing.
  . Data East Custom
    . DECO 55 / 56 / 74 / 141 Tilemap Generator: Allow masked priority behavior. Use shorter/correct type values. Fixed spacings.

    . DECO Karnov Sprites: Removed unnecessary configuration values. Use callback for color and priority behavior. Use shorter/correct type values. Reduced unnecessary lines.
  . Discrete Netlist
    . More structure for caches
    . Added power terminals to most logic devices. This fixes an over simplification. Logic devices implicitly assumed that GND/VDD actually is connected to GND(i.e. 0V). There is no immediate benefit from this change. It is a preparation for the future scalability. Now all power terminals (typically 7/14, 8/16) have to be explicitly connected to the supply rails. Also added a validation mode to the netlist core. This is not intended for running, but solely to better indentify pins which are not properly connected.
    . Bug fixes and nltool validation. nltool now supports a validate command which acts similar to MAME's validation.
    . Use A,B,C,... for packaged components
    . Runtime performance statistics can now be enabled with nltool option "-s". To enable those with MAME you need to run NL_STATS=1 ./mamenl64 -v -oslog game.
    . Minor optimization (netlist\nl_base.h and plib\pconfig.h)
    . All pstonum calls now need to specify if they want local locale or the "classic" "C" locale. Fixes MAME exception with -debug on Linux with some non-C locales (ID 06827).
    . Fixed memory leak when exception is thrown in constructor (plib\palloc.h and pmempool.h). Fixed Clang build (Clang treats -Wswitch-bool as error) (netlist\nl_base.h).
    . Protected defines in nl_config.h with ifdefs. Added a define to disable queue statistics during compile. This is only needed during development. Documented performance improvement efforts so I don't try this again.
    . Moved truth table implementation of 7448 in macro. At the same time added power terminals and update game netlists accordingly. Don't assume constructors will only throw things derived from std::exception (plib\palloc.h).
    . Converted NL_MAX_LINK_RESOLVE_LOOPS into a netlist parameter. Reduced potential bit-rot. nltool -v --version now displays values of all compile time defines. There are still far too many compile time defines. However, most of them ensure and test future scalability.
    . Only print queue stats if they are enabled. Fixed Breakout [TTL] SLOW_BUT_ACCURATE mode. Fixed include order and logging queue stats. OMP defines belong into pconfig.h since pomp.h - used by netlist - depends on them.
    . Provided example for state in truthtable. The truthtable implementation of 74107 (JK-Flipflop) is included for educational purposes to demonstrate how to implement state holding devices as truthtables. It will completely nuke performance for pong and therefore is disabled.
    . Switch to output array in devices\nld_9316.cpp. Fixed a warning in plib\ppmf.h.
    . Fixed CMOS 40xx and 4316 power pins and GCC-9 error
    . Removed base_dummy class and fixed CD4020 VCC/VDD
    . netlist_time array -> std::array (devices\nld_74161.cpp and nld_7474.cpp)
  . Flash ROM: Added 'SST 49LF020 Flash' to machine\intelfsh.cpp
  . Floppy: Uncluttered global name space as per Vas suggestion (formats\flopimg.h)
  . Hitachi HD6845S CRTC: More consistent identification of HD6845S variant (HD6845S same as HD46505S and HD6845 same as HD46505R)
  . IDT7200/1/2 FIFO: Separated device types by size. Allow side effects to be disabled for reads.

  . Keyboard: PC/AT and PS/2 101-key keyboard update. Still doesn't process commands from the host properly - not sure if it's a cpu or port issue (bus\pc_kbd\pcat101.cpp).
  . Konami Custom
    . K033906 PCI bridgep: Simplified handlers. Fixed some spacings. Converted arrays into std::unique_ptr.

  . Motorola MC6845 CRTC: Use standard device method to adjust input clock (video\mc6845.cpp)
  . PLA: Added optional logging to present the decoded terms
  . SCSI Bus: Disabled LOG_DATA_SENT by default to minimize log spam (machine\nscsi_bus.cpp)
  . SCSI Hard Disk: Verified stub. Windows NT setup uses the VERIFY command without data comparison (machine\nscsi_hd.cpp).
  . Sega Custom
    . Sega 16-bit common hardware: Moved palette shadow/hilight toggle bit function into palette handler (excpect hangon; it has external shadow/hilight toggle bit). Simplified some handlers. Fixed debugger issues and spacing. Use shorter/correct type values (machine\segaic16.cpp).

    . Identified some DIPs and added DIP locations according to Test Mode
  . Added opcode MOV_MT_A to NEC uPD7807 CPU (port T input threshold level; uPD7807 only)
  . Updated row selection in pteacher_keyboard_r, fixes inconsistencies reported in MT06473 (mjkojink and games based on it: Incorrect dipswitch reading). Still needs more work as DIPs for the second bank are inverted wrt how MAME expects them, but at least now all DIPs are useable.

  . Updated k573dio/k573fpga to use a proper algorithm for decrypting 'Dance Dance Revolution Solo Bass Mix (GQ894 VER. JAA)' audio. Fixed volume bug.
  . Full playability with all testable games. Fixed issues with remaining GFDM games. Fixed regressions with ddrextrm, ddrmax2, ddrsbm and dsem2. Attempt to fixed timing issues by emulating a buffer before the song actually plays. This value was found by choosing something that had a tight but known timing window (the Konami logo sound in DM10) and finding an offset that didn't allow you to hear it loop before the song end command was sent. Reverted changes for dynamic base address because I still can't figure out a more logical way that Konami could've implemented this. Use the last non-0 diff to fix some games.
  . Fixed bugs linked to the sample counter. Note: One thing to do would be to turn the 'Konami 573 digital I/O board' into a device_mixer_interface to have the connection to the speakers done at the driver device level [O. Galibert].

- Hot Blocks - Tetrix II: Hook up I2C EEPROM
- Invader's Revenge
  . Added sound. Currently clone (Game World, single PCB) has a bad dump sound rom.
  . Fixed interrupt (ID 07309). Note: The situation here with interrupts being acknowledged at a time nominally preceding the condition that triggered them suggests a disturbingly general problem with MAME's CPU scheduling. However, it should only affect machines in which such interrupt vectors are calculated from free-running counters (as this hardware does) rather than the more normal priority encoding of latched requests.
  . Cleaned up NMI code
- Juno First: Added raw screen parameters
- Klax: Simplified handlers and gfxdecodes. Fixed naming. Reduced unnecessary lines. Use shorter/correct type values.
- Konkyuu no Hoshi: Added missing video-related interrupt and reguess VIA clock
- Mahjong Diplomat [BET] (Japan): Updated DIPs (ID 05553)
- Megadrive hardware: Use color lookup. Reduced unused. Added device_palette_interface (machine\mega32x.cpp; drivers\hshavoc.cpp, megadriv_acbl.cpp, megaplay.cpp, megatech.cpp, puckpkmn.cpp and segac2.cpp).
- Midnight Landing: Simplified handlers. Reduced duplicates, runtime tag lookups and unnecessary lines. Use shorter/correct type values.
- Momoko 120%: Simplified handlers. Reduced runtime tag lookups and unnecessary lines. Fixed namings and spacings. Use shorter/correct type values.
- Mosaic: Decapped PIC16C55 for Mosaic. Not hooked up yet.
- MX5000: Correct CPU type
- Puzzle Time: Splitted palettes and converted screen update to RGB32
- Quiz Olympic: Clean up VRAM banking, screen update and converted to RGB32. Clean up ROM banking. Use XTAL values. Added COIN2 and document more dipswitches.
- Rebound: Performance optimization
- Return of the Invaders: Soundlatch modernization
- Route 16: Fixed missing right-side walls in main map of Route 16 and clones Route 16 (set 2) and Route 16 (set 3, bootleg?) (ID 07310). Note: New code to better emulate the protection was added in MAME 0.194, but it turned out to harbour a bug (see MT#07310). Therefore the previous patches have been restored, and the protection routine has been nullified (but still there in case someone wants to revisit it).
- Star Rider: Added AMD/Plessey 2812 FIFO device (for WIP Star Rider driver)
- Strike Bowling: Fixed cocktail mode grapics (ID 07325). Added P2 button1 for cocktail mode. Note: Cocktail mode still not working, the horizontal sprite positioning is wrong when the screen is flipped.
- Super Real Darwin: Fixed srdarwin_draw_sprites priority checking behavior
- Total Vice: Redumped clone Total Vice (ver AAB) CD-ROM
- Tutankham: Implemented starfield and better colors (ID 02932). Used color code from galaxian for better color approximation. The starfield code was added to better document the 084 custom chip. There are two star fields implemented now. The active one can be selected in Machine Configuration. a) Scramble Starfield: 1/3 star width like scramble/galaxian, starfield code same as scramble. This one is similar to the Konami starfield video below. The 084 uses the same signals as scramble. b) Bootleg Starfield: Guru provided schematics of a daughter-board which on a Konami bootleg replaced the custom chip 084. This starfield matches the starfield (picture) of this bootleg. At least there is now a starfield which matches a real-life(tm) bootleg. None of the two alterntives reproduces the star field which can be observed in the Stern videos on YouTube. The Konami video mentioned in video\tutankhm.c is different from Tutankham. Looks like we are missing an early board dump.
- Vector games (Atari AVG/DVG): Removed hardcoded tags and runtime tag lookups. Simplified handlers. Reduced unnecessary lines. Fixed spacings, some code styles and namings. Use shorter/correct type values (video\avgdvg.cpp; drivers\asteroid.cpp, bwidow.cpp, bzone.cpp, mhavoc.cpp, omegrace.cpp, quantum.cpp, starwars.cpp, tempest.cpp and tomcat.cpp)
- Wizz Quiz: Don't know how this escaped modernization
- Zig Zag: Fixed game hangs when you play a 2 Player game (ID 07332)
- Fixed rom names in avalnche.cpp, berzerk.cpp, flkatck.cpp, m72.cpp, segahang.cpp, seta2.cpp, taito_f3.cpp, tatsumi.cpp and vicdual.cpp
- Dipswitch fixes in 8080bw.cpp, by35.cpp, homedata.cpp, quizo.cpp and statriv2.cpp
- Description changes of Carnival (upright, AY8912 music), Football Power (Version 1.2), Hang-On (Rev A, ride-on), Parent Jack (Japan), Last Fortress - Toride (Japan, VG420 PCB), Royal Card (Nichibutsu HW), 'Player's Edge Plus (PP0550) Joker Poker (Two Pair or Better, set 3)' and Tetris (D.R. Korea, set 1, encrypted)
- Renamed (boxyboy) to (boxyboya), (pepp0550a) to (pepp0550b) and (sfex2) to (sfex2u)
- Linux
  . Added python to list of required ubuntu packages (docs\source\initialsetup\compilingmame.rst)
  . Documented Linux Lightguns with Xinput. Added a new doc page within the 'Advanced Configuration' section which describes how to enable Lighuns on Linux using the XInput lightgun provider (docs\source\advanced\linux-lightguns.rst).
  . Enabled Xinput support by default on Linux. The Xinput lightgun driver is the only reliable+accurate method to use lightguns on Linux, we should enable this by default to reduce the friction for Linux Lightgun users. This should have no effect on users of Windows/Mac etc (makefile and osd\sdl.lua). Fedora users need libXi-devel now that X11 XInput is enabled by default - no clue about other Linuxes (docs\source\initialsetup\compilingmame.rst)
- MAME
  . VIDEO RENDERING SYSTEM
    . Converted screen update functions to RGB32 in numerous games. This is intended to expedite CRTC-based video modernization (4roses.cpp, 5clown.cpp, albazg.cpp, amaticmg.cpp, aristmk4.cpp, avt.cpp, bmcbowl.cpp, buster.cpp, calomega.cpp, carrera.cpp, chance32.cpp, coinmstr.cpp, docastle.cpp, fastinvaders.cpp, fortecar.cpp, funworld.cpp, gluck2.cpp, goldnpkr.cpp, goldstar.cpp, hitpoker.cpp, jokrwild.cpp, jubilee.cpp, kingdrby.cpp, luckgrln.cpp, magicfly.cpp, majorpkr.cpp, mpu12wbk.cpp, mpu4dealem.cpp, murogem.cpp, nibble.cpp, peplus.cpp, progolf.cpp, rgum.cpp, royalmah.cpp, sanremo.cpp, skylncr.cpp, snk6502.cpp, speedatk.cpp, summit.cpp, supercrd.cpp, tmspoker.cpp, toaplan1.cpp, truco.cpp, twincobr.cpp, usgames.cpp, vlc.cpp and wardner.cpp)
    . Fixed screen_device::update_now() when drawing partial lines. Fixed pixel-access functions to use the current bitmap (emu\screen.cpp).
  . DEVICE
    . Added sanity check to emu\distate.cpp
    . Simplified handlers (emu\tilemap.cpp, machine\74259.cpp, adc1213x.cpp, huc6202.cpp, huc6260.cpp, huc6261.cpp, huc6270.cpp, igs017_igs031.cpp, voodoo.cpp)
    . Reduced unnecessary handlers (drivers\gradius3.cpp, machine\atarigen.cpp)
  . UI
    . Allow palette alpha value viewable (ui\viewgfx.cpp)
    . Privatized a few variables. Provided more helpers (ui\menu.cpp).
  . INPUT PORT
    . Improved sorting of items for machine input menu. Inputs of the same type are sorted by name, and keyboard keys are sorted by their assigned character codes (if any) (ui\inputmap.cpp).
    . Disabled WII Lightgun hack by default
  . LUA engine
    . Improved comments (fixes and updates). Fixed/Added comments for emu.thread(), machine:popmessage(), watch/breakpoints, debugger presence note, val for write functions, input:seq_poll*, memory_share library, explain emu.register_callback(callback, name) and emu.step().
    . Added machine_flags library. Make machine_flags fields of game_driver rather than a new table.
  . PLUGINS
    . hiscore.dat update (plugins\hiscore\hiscore.dat)
    . Added plugin for autofire: Hardcoded autofire plugin. Changed register_frame to register_frame_done, removed pause check. Added support for multiple buttons loaded from a file. Implemented saving settings on quit. Fixed multiple keybindings for same button from overwriting each other. Replaced double-quotes with single-quotes. Refactored saving/loading into a separate module. Changed button format to use input_code rather than string token. Settings format is unchanged (still saved as string token). Rewrote table initialization in save/load. Implemented menus. Added helper messages for "on frames"/"off frames". Fixed bugs related to reloading roms. Soft resets would reload autofire settings without saving them first, causing the settings to be lost. This commit adds a check to only reload from the settings file if loading a different rom than before. Hard resets would leave bad references lying around, causing MAME to crash under certain circumstances (i.e. resetting while in the edit menu and entering the menu again). This commit makes sure to properly clean up and reinitialize menu and button states when resetting. Used set_folder to avoid hardcoding plugin name in settings path.
  . RAM auto-sharing is going away, so fix drivers relying on it (drivers\ambush.cpp, amiga.cpp, appoooh.cpp, armedf.cpp, astrocde.cpp, atarig1.cpp, atarig42.cpp, atarigt.cpp, atarigx2.cpp, bagman.cpp, banctec.cpp, batman.cpp, bingor.cpp, by68701.cpp, cball.cpp, ccastles.cpp, cclimber.cpp, contra.cpp, coolridr.cpp, cps2.cpp, crystal.cpp, ddragon.cpp, deadang.cpp, eprom.cpp, equites.cpp, expro02.cpp, feversoc.cpp, fitfight.cpp, gaelco2.cpp, gaelco3d.cpp, galaxian.cpp, galaxold.cpp, gamepock.cpp, goindol.cpp, hvyunit.cpp, ironhors.cpp, legionna.cpp, liberate.cpp, liberatr.cpp, ltd.cpp, m62.cpp, maygayep.cpp, maygayv1.cpp, mgolf.cpp, midvunit.cpp, mps1230.cpp, namcos12.cpp, namcos23.cpp, nemesis.cpp, nmk16.cpp, o2.cpp, olibochu.cpp, punchout.cpp, realbrk.cpp, rocnrope.cpp, rohga.cpp, scv.cpp, senjyo.cpp, seta.cpp, skimaxx.cpp, ssv.cpp, stfight.cpp, subs.cpp, subsino2.cpp, swtpc09.cpp, tagteam.cpp, tankbust.cpp, taxidriv.cpp, tbowl.cpp, wecleman.cpp, wiping.cpp, yiear.cpp, zaccaria.cpp, audio\cage.cpp).

- Pickin': Changed Pickin' to use an 8-way joystick as it should be per notes from original board owners. Also added confirmed bonus life DIP and updated locations to match same notes.
- Return of the Jedi: Simplified handlers. Added gfxdecode for debug and palette_device for palette handling. Reduced runtime tag lookups. Fixed some drawing routines, namings and spacings. Reduced unnecessary lines. Use shorter/correct type values. Added notes.
- Road Riot's Revenge: Mark dumps of protected PALs as NO_DUMP, as they contain no info at all.
- RyuKyu: Added FD1094 317-5023a.key to 'RyuKyu (Rev A, Japan) (FD1094 317-5023A)' (Game now playable).
- Shuriken Boy: Dumped proms
- Strikers 1945: Start splitting up the MCU handlers
- Sky Base: Added 'Cabinet' dipswitch, fixes inverted upright and cocktail switches (ID 07347).
- Space Cruiser: Fixed Cabinet and Flip Screen dipswitch (ID 07354)
- Star Rider: More notes
- Team Hat Trick: Fixed Player 3 and 4 reversed joystick inputs
- Tutankham: Small cleanup
- Waku Waku Ultraman Racing: Added DIPs and identified bits used by the wheels. Needs proper wheels emulation.
- Wonder Boy III: Decrypted clone Wonder Boy III - Monster Lair (set 6, World, System 16B) (8751 317-0098). Still not working because GFX and sound need to be emulated correctly.
- Fixed rom names in leland.cpp, pingpong.cpp and cpzodiac.cpp
- Dipswitch fixes in bagman.cpp, chanbara.cpp, dfruit.cpp, segas16b.cpp, seta.cpp, system1.cpp and taitosj.cpp

- MAME
  . VIDEO RENDERING SYSTEM
    . Moved additive blending function into emu\drawgfx.h. Added priority related copybitmap functions. Fixed spacings. Added priority related copybitmap and draw_scanline function is sprite like priority handling(prio_*) and tilemap like priority handling(primask_*). These are helpful for priority related bitmap/scanline drawing routines (emu\drawgfx.cpp). Added variations of priority related pixel draw functions. Fixed spacings (emu\drawgfxm.h). Added example usage for prio_copybitmap to video\realbrk.cpp and add_blend_r32 to video\hng64.cpp.
    . Added packed and raw case of generic gfx layouts. Added example usage to f1gp.cpp, pgm2.cpp, powerins.cpp and psikyosh.cpp.
    . Added screenless base class (devices\video\pwm.cpp/h). Make screenless a device. Use pwm_display_device for (MESS) hh_tms1k.cpp, tispeak.cpp and tispellb.cpp.
    . Default SVG region (emu\screen.cpp)
    . Since value is unsigned, it will never be lower than zero (emu\render.cpp).
    . Solve the quit-on-minimize problem (render\drawgdi.cpp, drawnone.cpp, drawogl.h and drawbgfx.h)
    . Fixed D3D alt-tab crash (render\drawd3d.cpp)
  . MEMORY SYSTEM
    . Fixed subtle memory subsystem bug (emu\emumem_mud.cpp)
    . Make submaps work with address-shifted spaces. Note that submaps are now assumed to use an address shift of 0. It is possible, though unlikely, for this to cause some breakage (emu\addrmap.cpp and emumem.cpp).
  . PLUGINS: Changed autofire config directory to homepath (plugins\autofire\autofire_save.lua and init.lua)
  . Eliminated legacy callback syntax (template  devcb_base &set_?_callback/handler(?) { return...}; emu\devcb.h, screen.h, cpu\nec\v25.h, s2650\s2650.h, machine\74175.h, ataintf.h, cr511b.h, eepromser.h, i8212.h, i8251.h, namcos21_dsp_c67.h, pci-ide.h, sound\2203intf.h, 2608intf.h, 2610intf.h, 2612intf.h, 3526intf.h, 3812intf.h, es5503.h, ics2115.h, mos6560.h, msm5205.h, nes_apu.h, s14001a.h, spu.h, video\psx.h, v9938.h, audio\dsbz80.h)
  . Defaulting to empty search path if null (emu\machine.cpp)
  . Added focus next/previous input types, will be hooked up later (emu\inpttype.h and ioport.h).
  . Device Network Interface: Added loopback control (emu\dinetwork.cpp)
  . Fixed ppc64el issue. This is probably due to the fact that IBM 128bit long double format is not constant folded. Slighlty rewrote ""_kHz_XTAL(long double clock) and ""_MHz_XTAL(long double clock) the way ""_kHz_XTAL(unsigned long long clock) and ""_MHz_XTAL(unsigned long long clock) are written. Compensate for floating-point rounding errors when converting to integer value (emu\xtal.h).
  . Make more use of the NODEVICE_LAN flag
  . Validity
    . Be more verbose when validating device type (emu\validity.cpp)
    . Fixed -validate errors detected and assured it passes xmllint (hash\cd32.xml)
- Linux: Overhaul to advanced gun instructions. This cleans up spelling and other issues in the original text. This work is still prototype and will probably require fine-tuning (docs\source\advanced\linux-lightguns.rst).
- Compiling
  . travis.yml: Added libxi-dev to Travis Linux Config
  . Fixed VS LLVM configuration: dxsdk was missing from includes. winmm was missing from libs. Narrowing warning was silenced for VS, but not from vsllvm, where it leads to an error in menu_video_options::handle() (scripts\genie.lua and osd\modules.lua).
- Debugger: Fixed fatal error when attempting to set watchpoint covering unaligned portions of two adjacent native words (debug\debugcpu.cpp)
