Fixed MBUS and DMA irq routing (m68000\mcf5206e.cpp).
  . Intel 8031/8051/8751: Removed spurious port read messages (mcs51\i8051.cpp)
  . Intel 80186: Added latency when writiing DMA registers before the next DMA starts. Fixes (MESS) MPC60 crashing and the other drivers using a '186 all behave identically to 0.280 (i86\i186.cpp).
  . Intel 8257 DMA Controller: Make the driver handle verify cycles since the DMAC only does an address strobe (machine\i8257.cpp)
  . Intel I386: Set CPl after all memory reads are done in i386_task_switch (i386\i386segs.hxx)
  . Texas Instruments TMS320C3x: ABSF opcode was mistakenly using ~man instead of -man, causing problems for MK4 which checks whether |A|+|B| == |A + B|. Fixes walking both players toward each other would result in no collision (tms32031\32031ops.hxx).
- DEVICE
  . Floppy: Documented all of the upd72069 auxiliary commands (machine\upd765.cpp)
  . MB89371 Dual Serial UART: Rewrite MB89371 as a fully functional device (machine\mb89371.cpp)
- cdi.cpp: Fixed XA audio peaking by decoding in 32-bit and clipping to 16 later (philips\cdicdic.cpp). Simplified mouse position-update logic (philips\cdislavehle.cpp).
- goldstar.cpp
  . Cherry Master '97 improvements: Decoded and bitswapped the bipolar PROMs creating a RGB555 palette. Fixed title and foreground graphics colors. Video register from port to get the proper graphics modes. Adjusted and placed the reels properly. Added hopper support, mechanical counters and lamps. Fixed the reels colors and the screen update to use the vidreg for modes. More work on memory map, ports, hooked video registers, worked video hardware, reels tile info, screen update and palette/color index for different elements. Added double-up girls support with scroll, new inputs from the scratch and buttons-lamps control panel layout. Added Cherry Master '97 'Double Up Game', 'Double Up Type', 'Double Up Girls' factory forced DIP switches. Splitted inputs for Cherry Master '97 sets 2 & 3.  Fixed DIP switches polarity and defaults for cmast97, cmast97a and cmast97b. Splitted inputs for Cheri Mondo '97. Added 'Reels Speed' DIP switch to cmast97, cmast97a and cmast97b. Promoted Cherry Master '97 (V1.7, set 1) and clones Cherry Master '97 (V1.7, set 3, no girls) and Cheri Mondo '97 (V1.4I).
  . Cherry Master 97 (bootlegs running in different hardware) huge improvements: New machine config, machine start, bankswitching, memory map, port map, video registers, screen update, graphics decode, inputs, ROM load fix, lamps and button-lamps control panel. Added Double Up Type DIP switch (3 / 5 cards) and added the missing layout. Promoted Cherry Master '97 (v1.6, bootleg) and Cherry Master '97 (v1.8, bootleg) to working.
  . Jackpot Knight improvements: Fixed title and foreground colors and reels colors. Improved reels placement. More work on ports map, hooked video registers, worked video hardware, new machine config, proper screen update and proper graphics decode. Improved inputs. Added a new port to handle the Jackpot Knight reels background colors. Added Reels Speed DIP switch. Added 'Reels Speed' DIP switch. Switched DIP switches to Skill/Stops mode for default. Added buttons-lamps control panel. Promoted Jackpot Knight (V1.1) to working.
  . New Fruit Bonus '96 Special Edition: Removed all loaned bipolar PROMs from clones nfb96se, nfb96sea, nfb96seb, nfb96sec, carb2002 and carb2003 and decoded the proper device data for palette. Fixed the rom load of clones nfb96se, nfb96sea, nfb96seb, nfb96sec, carb2002 and carb2003 taking care of the proper graphics bitplanes. Removed the imperfect color flag of the above games. Marked clone carb2003 reels graphics ROMs as bad dump. Flagged the game as imperfect graphics. Temporal workaround bypassing some checks for clone noved.
- model2.cpp
  . Fixed textured mesh polygons. Need to double all the increment values (sega\model2rd.ipp).
  . New trilinear implementation, runs about 40% faster. Added support for microtextures (sega\model2_v.cpp and sega\model2rd.ipp). Pre-bind render callback delegates (sega\model2_v.cpp).
  . Limit microtexture blend factor to 127/256. Prevents microtextures being drawn when the base texture is transparent, fixes wallpaper in hotd (sega\model2rd.ipp).
  . Draw polygons front to back, use fill buffer. The real hardware has two 32Kx8 RAM chips described in the Model 2B manual as "fill memory"; these effectively function as a pair of 1-bit depth buffers, one for each framebuffer. Performance is improved over back-to-front rendering, particularly in more intensive scenes, since pixels that would be drawn where other pixels have already been drawn can be discarded early before texture mapping is performed.
- namcos23.cpp: Eliminated some switch/case statements through direct read/write handlers for certain registers
- pgm3.cpp: Fixed endianness bug - you can't just access a 32-bit ROM region as bytes.
- Funcube: Original Funcube uses TMP68301 not Coldfire, fixes black screen regression (ID 09271).
- Funcube 2/3/4/5: Make MCF5206E CPU accept external interrupts, fixes CPU space. Provide MBAR relocation and GPIO reads, fixes Funcube 2/3/4/5 battery regression (m68000\mcf5206e.cpp).
- Gold Line: Added ROM and reel RAM banking and identified game title as Gold Line.
- Renamed (cmast97a) to (cmast97b), (scmaster) to (scmastera) and (unkct) to (goldline)
- Dipswitch fixes in goldstar.cpp

- MAME
  . PLUGINS: Fixed mixed space/tab indentation (plugins\hiscore\init.lua)
  . Consolidate drivers into single files (kingobox.cpp)
  . DEVICES: Added more sanity checks to device types. This will bloat debug builds a bit, but unfortunately it seems to be necessary to explicitly guard against this now (emu\device.h).
- Compiling
  . Cleaned up code (cpu\t11\t11ops.hxx, video\poly.h, igs\spoker.cpp, sega\model2.h, sega\model2_v.cpp, sega\model2rd.ipp)

- Bob Zed (What's new): https://youtu.be/60y20tKb9F4
- CPU
  . DEC T11
    . Handle unaligned accesses to I/O page. Certain devices on bk, uknc require this, as they do not handle the WTBT bus signal and always decode full address (t11\t11.cpp).
    . Improved interrupt handling in K1801VM1 CPU core. Added interrupt processing and EIS instructions to K1801VM2 core (t11\t11.cpp).
  . Dynamic Re-Compiling
    . drcbec
      . Fixed code for ROLC that played fast and loose with integer promotion, producing incorrect results for some compilers/targets (cpu\drcbec.cpp).
      . Fixed default floating point rounding mode not applying after RESTORE (cpu\drcbec.cpp).
    . drcbex86
      . Clear the zero and carry flags for unordered floating point comparisons for consistency with the documentation and the other back-ends (cpu\drcbex86.cpp).
      . Mask flags when setting via SETFLGS or RESTORE to avoid possible buffer overrun, slightly optimised SETFLGS with an immediate operand. Optimised FCMP when only the unordered flags is required (cpu\drcbex86.cpp).
      . Optimised GETFLGS: LEA to avoid the need to save/restore flags for more flag combinations, choose registers more wisely to avoid unnecessary copies and reduce REX prefixes, use more efficient strategy to save and restore flags. Removed assert that made SETFLGS impossible to use in debug builds. Removed casts that are no longer necessary (cpu\drcbex86.cpp).
    . drcbex64
      . Clear the zero and carry flags for unordered floating point comparisons for consistency with the documentation and the other back-ends. Slightly optimised flag calculation for some shifts and rotates (cpu\drcbex64.cpp).
      . Simplified and ptimised flag calculations for rotate instructions (cpu\drcbex64.cpp)
      . Mask flags when setting via SETFLGS or RESTORE to avoid possible buffer overrun, slightly optimised SETFLGS with an immediate operand. Optimised FCMP when only the unordered flags is required (cpu\drcbex64.cpp).
      . Avoid slow microcoded pushfq/popfq altogether. Also avoid some false dependencies and reduce near cache usage by almost 4KiB (cpu\drcbex64.cpp).
      . Optimised a couple more cases of GETFLGS and replaced a few magic numbers with constants. Use 2-operand and 3-operand forms of imul. Also changed scratch register use a bit. Optimised MULU/MULS flag calculation. Removed assert that made SETFLGS impossible to use in debug builds. Removed casts that are no longer necessary (cpu\drcbex64.cpp).
    . drcbearm64
      . Use bfxil to save an instruction for smae cases of CARRY and ROLINS (cpu\drcbearm64.cpp)
      . Fixed default floating point rounding mode not applying after RESTORE. Optimised generated code for SETFLGS a little (cpu\drcbearm64.cpp).
      . Save an instruction when calculating carry flag for shifts with immediate count. Optimised MULU/MULS flag calculation. Handle degenerate forms of ROLAND/ROLINS when simplifier is disabled. Removed assert that made SETFLGS impossible to use in debug builds (cpu\drcbearm64.cpp).
      . Further optimised 32-bit multiplication and flag calculation for all multiplication instructions. Fixed 32-bit SEXT sign extending to 64 bits. Removed casts that are no longer necessary (cpu\drcbearm64.cpp).
      . Don't try to get offset of unbound labels even if it won't be used (cpu\drcbearm64.cpp)
    . ST0016: Moved ROM banking from drivers into device. External ROM is now read through an address space. Also reduced literal tags, suppress side effects for debugger reads and cleaned up code.
    . UML: Truncate immediate operands for CARRY (cpu\uml.cpp). Marked BREAK as clobbering all flags and marked LOAD, LOADS, STORE, SET, FLOAD and FSTORE as not modifying flags. CPUs already depend on SET not modifying flags (cpu\uml.cpp).
    . PowerPC drc: Generate a simpler multiplication opcode for MULLI (powerpc\ppcdrc.cpp)
    . x86/x64 code logging helpers: Encapsulated as a class, don't use unsafe sprintf, optimised a little, made comments and data ranges vectors (cpu\x86log.cpp).
    . Doc: Documented the last of the UML instructions (docs\source\techspecs\uml_instructions.rst)
  . Hitachi HD63705Z0: Use logmacro logging (m6805\hd6305.cpp)
  . hyperstone E1: Optimised generated code for multiplication and DSP instructions a little. Fixed recompiler not sign-extending EHMAC inputs (interpreter was correct) (e132xs\e132xs.h, e132xs\e132xsdrc_ops.hxx).
  . Intel 8086: Avoid clearing working registers upon device reset (i86\i86.cpp). Note: This change is required in order for BIOS for the AT&T 6300 Plus to work. The 6300 Plus has external logic to reset the 80286 via the reset pin, so that it can return to Real Mode from protected mode. Upon return to Real Mode, the BIOS code is clearly depending on the fact that SP register is preserved upon reset (the BIOS does however explicitly load the SS register after reset, before it is used). The 8086 and 80286 documentation call out which registers are to be initialized upon reset, and SS is one of them. For AX, BX, CX, DX, BP, SP, SI and DI, the behaviour is not specified. However, based on what the 6300 Plus BIOS is doing, it appears the actual hardware behaviour is to leave them untouched. Although we can only be fully confident that the real 286 behaves this way with respect to the SP register, it's likely that the other registers which do not have explicitly defined initialization behavior are also not touched during reset. Note that this observed behaviour only pertains to reset via the reset pin, and not to power-on initialization.
  . Intel 80960KA/KB
    . Only trigger interrupts if the input changes to the asserted state (i960\i960.cpp). logr and logrl use base 2 and always use correct rounding mode (i960/i960.cpp).
    . Split check_irqs() into two separate functions, fixes "Fatal error: I960: 2f2f2f2e: Unhandled 00" during Self-Test in vf2o, overrev and sgt24h (ID 08347). Pending interrupts are only checked after returning from an interrupt, while executing modpc if it causes the current priority to be lowered, and after receiving a test pending interrupts IAC message (i960\i960.cpp).
    . Fixed typo in ROUNDRL instruction (i960\i960.cpp)
  . MCS-51
    . Fixed destination RAM type in XCHD A, @R0/@R1. The initial value is read from internal RAM (IRAM_IR). The final value must be written to the internal RAM too (IRAM_IW instead of IRAM_W) (mcs51\mcs51ops.hxx).
    . Renamed the external data bus from io to data. Start turning the internal maps into real maps. Modernization step 1+2 (mcs51\mcs51.cpp)
  . NEC uPD7810: Added internal layout and complete driver implementation for (MESS) Roland PG-1000 (upd7810\upd7810.cpp, roland\roland_pg1000.cpp)
  . Texas Instruments TMS7000: Clean up code in disassembler (tms7000\7000dasm.cpp)
  . Toshiba TMP95C06x: Fixed uninitialised members. Also got a lot of stuff out of the header that doesn't need to be there (tlcs900\dasm900.cpp). Show SFR symbols in disassembled code for names for TMP95C061, TMP95C063 and TMP96C141.
  . Zilog Z80: Cleaned up unnecessary internal state validation (SA_BUSACK) which caused INT skip (z80\z80.cpp)
- DEVICE
  . 8042 Keyboard/Mouse Controller: Can't possibly receive if the timer isn't running. Fixed PCIAGP boot without debug tricks (machine\8042kbdc.cpp).
  . Flash ROM: Added ST_M29W640FT and implemented unlock bypass command. Support for Winbond W29C020C + preliminary Winbond SDP mode (machine\intelfsh.cpp)
  . Floppy
    . Support quad density floppies as an option. Disable option ROM on fixed disk controller (onboard BIOS has built-in support). Use a lambda instead of short function (isa\fdc.cpp).
    . Added rudimentary error checking to floppy_create, allow mount to return nullptr on failure. Fixed error return for floppy_create (tools\floptool.cpp, tools\image_handler.cpp). Sanity check for debug builds (formats\fsblk_vec.cpp).
    . Added 8bit DMA and NOP unknown FDC commands to (MESS) MPC-3000 (machine\upd765.cpp). Added uPD72069 data rate control (machine\upd765.cpp)
    . New filesystem-based commands: Added flophashes and hdhashes commands to compute CRC-32 and SHA-1 hashes for each file on a floppy or hard disk image. Added flopchmeta command to change the metadata for a file, directory or volume on a floppy image. Added floprename and flopremove commands (tools\floptool.cpp).
  . Hitachi HD44780 LCD Controller: Reorganized the classes so that the a0* bad dump do not propagate to systems not using it (video\hd44780.cpp). Removed the parent roms stuff because we do not have a parent concrete device anymore (video\hd44780.h).
  . IGS017_IGS031: Don't hardcode tilemap ROM size in decryption function (igs\igs017_igs031.cpp), fixes 'Krazy Keno' which has bigger ROM [Osso].
  . Intel 8259 PIC: Side effect protection
  . ITE IT8705F LPC Super I/O: Fixed FDC DRQ line setup. Hookup ISA DMA bindings (machine\it8705f.cpp).
  . Konami 056832 Tilemap Generator: Got rid of a redundant function with duplicated code (konami\k054156_k054157_k056832.cpp)
  . NMK112: Use configured banking rather than writing to ROM regions. Handle non power of two ROM sizes properly (machine\nmk112.cpp).
  . NVRAM: Removed DEFAULT_RANDOM init (machine\nvram.cpp)
  . RS-232 Port: Added option for (MESS) Heath H19 terminal. Changed to the option function to a static method.
  . SEI80BU Encrypted Z80 Interface: Moved SEI80BU emulation into its own source file (seibu\sei80bu.cpp). SEI80BU is not always part of the Z80-based sound system, e.g. seibu\mustache.cpp. Also added input frequencies for SEI80BU devices (uses the same clock as the Z80).
  . Seta ST0020/ST0032 Sprites: Made ST0020 and ST0032 separate devices. Use util::sext for sign extension. Suppress side effects for debugger reads, use logmacro.h for configurable logging (seta\st0020.cpp).
  . SiS 950 LPC Super-South Bridge: Hookup ISA DMA bindings (machine\sis950_lpc.cpp)
  . Taito TC0110PCR: Use callback and configuration for color format and address shift. Also use logmacro.h for logging and suppress side effects for debugger reads (taito\tc0110pcr.cpp).
  . Toaplan Text tilemap generator: Merged common text layer emulation in GP9001-based drivers into a device (toaplan\toaplan_txtilemap.cpp)
  . Winbond W83977TF Super I/O: Hookup FDC, GPIO1, FDC irq and drq lines. Ensure Super I/O port to be installed after the others. Hookup ISA DMA bindings and fixed floppy fails (machine\w83977tf.cpp).
  . Z80 CTC: Improved interrupts handling in (MESS) specnext (machine\z80ctc.h)
  . Zilog Z80 DMA Controller: Always return live status regardless of when read command was sent (ID 09143). Refactor read register emulation. Minor logging refinements and cleanups (machine\z80dma.cpp). Keep member declarations together (machine\z80dma.h).
- SOUND
  . Ensoniq 5505/5506 to 5510 interface: Route es5505 bus to a separate 'aux' stereo output. The VFX-SD and later keyboards in the family have not only a main stereo output, but also a second 'aux' stereo output that bypasses effects processing and has separate output jacks from the keyboard. This allows some sound to be routed for separate effects processing or recording (sound\esqpump.cpp and ensoniq\esq5505.cpp).
  . Ensoniq ES5505/6: Devices generate 20bit samples, not 16-bit ones.
  . Yamaha SWP30 sound chip: Overhaul. Use util::sext and explicit specializations for std::clamp and std::min. Removed crashing debug fopen/fprinf and srcclean (sound\swp30.cpp)
- astrcorp.cpp: Adding passwords in ASCII format
- astropc.cpp: Split passwords from astrcorp.c in astropc.c notes where they belongs and added romset IDs. Added missing passwords ASCII tables.
- blmbycar.cpp and wrally.cpp
  . Use device_video_interface to obtain screen. Also lifted a calculation out of the inner sprite drawing loop and cleaned up code (gaelco\gaelco_wrally_sprites.cpp). Implemented device_gfx_interface (gaelco\gaelco_wrally_sprites.cpp).
  . Suppress side effects for debugger reads and cleaned up code (gaelco\blmbycar.cpp). Cleaned up code (gaelco\wrally.cpp).
- dassault.cpp: Fixed priority write function. Fixes regression since MAME 0.194 (Get rid of nonbuffered_palette_w in video\decocomn.cpp).
- dbz.cpp: Reduced duplication and cleaned up code. Use object finder arrays and templates to reduce duplication and reduce literal tags. Use BIT helper, improved ROM region names and made more local variables const.
- ddenlovr.cpp and dynax.cpp
  . Correct half the DIP switches for Mahjong Jongoh based on an auction photo of the manual
  . Added preliminary hanaroku panel support to Hanafuda Hana Ginga
  . Better representation of the buttons that are actually present (dynax\hanafuda.cpp)
- es9501.cpp
  . Changed IRQ handling so that 'Dream 9 Flower' does palette updates and inputs. Dumped correct EEPROM for the Dream 9 Flower and clone.
  . Real 93C56 EEPROM dump for Special Dream 9 (v1.0.7G). Added real EEPROM dump for Star Ball (v1.0.0S).
- gaelco2.cpp
  . Moved dual monitor variant to a separate driver state class. Lifted a calculation out of the inner sprite drawing loop. Reduced duplication and suppress side effects for debugger reads.
  . Make use of DS5002FP programs built from Gaelco archives for the first 2 World Rally 2 sets, older sets still use the ROM found on dumped boards.
- giclassic.cpp: Added missing member to saved states
- goldstar.cpp
  . Driver improvements. A huge work on tilemap system, machines config, memory maps, video start, screen update, tile get info, gfxdecode and different video registers to give extended graphics support (mostly girls) to Poker Master and derivative hardwares. Now the sets that support girls are pkrmasta, missbingo, missbingoc, crazybon, crazybona and crazybonb. First titanic pass to reorganize and clean goldstar.cpp driver.
  . New machine config for '3 Cards Poker 96'. Correct settings for NVRAM. Bypassed the '3 Cards Poker 96' protections. Improved, optimized and unified the protection bypass for both sets. Unified the inputs for both sets. Simulated protection instead of patching it out. Promoted 3 Cards Poker 96 (V1.6) and 3 Cards Poker 96 (V1.0) to working.
  . Extended graphics/girls support (8.u53 rom) to all Lucky Line III sets. Created buttons-lamps control panel layout. Extended NVRAM. Also added a dump of original 6264 NVRAM for future analysis.
  . Fixed the constant noise sound problem in Lucky Lady (Wing, encrypted) and Tic Tac Toe (Sundance bootleg of New Lucky 8 Lines).
  . More work toward clone cutylineb. Memory map and machine config. Redumped cutylinea and cutylineb bipolar PROMs. Removed the loaned girls ROM from clones cutylinea and cutylineb, due to is inexistent on the PCB. Added workaround to get clone cutylinea running the attract. Added temporary hacks to clones cutylinea, cutylineb and cutylinec, to get them working.

Adjusted final mix to capture the true highest bits, don't retrigger the filter envelope on writes and decode the loop parameters. More plausible loop point calculation. Updated documentation. Further work on loop parameters. The crowd in Xtreme Rally now sounds reasonable. Additional cleanup, proper logging, device map and multichannel output. Also changed owners/licensing given extensive rewrite since 0.280. Added DMA support. 16-bit linear sample format supported. Remap the channel mapping to make sense. Better logging. Cleanup, improved logging, fixed missing address mask, fixed issue with 16-bit playback and added enum for output channels. Make into a device_memory_interface with a side of memory_access cache (sound\l7a1045_l6028_dsp_a.cpp).

Converted render callbacks to C++ member function templates (sega\model2rd.ipp).
  . Improved interrupt logic: Interrupt control register only returns interrupts actively signalled to the i960; masked interrupts are not returned. Sound IRQs are triggered when either TxRDY or RxRDY from the USART is active (Model 2B manual, section 6.2). Removed model2c_interrupt callback; no evidence that Model 2C behaves any differently to earlier board revisions. Removed vcop issue from TODO list since it no longer occurs (tested) (sega\model2.cpp).

- nss.cpp, sfcbox.cpp, snesb.cpp and snesb51.cpp
  . Fixed status flag display in emulation mode. In emulation mode, "MX" are " B". Both bits are always 1, only the semantic meaning changes: " " doesn't exist, and "B" is only meaningful when pushed during an IRQ/NMI, to distinguish from BRK (g65816\g65816.cpp).
  . Fixed IRQ to be level triggered. Followup b3f2535: stop clearing LINE_IRQ when jumping to the IRQ vector. Properly written IRQ handlers won't notice any difference, but this fixes the behavior for software which (possibly intentionally) fails to clear an IRQ source; in that case the IRQ should continue to trigger (probably leading to a system hang). LINE_SO is generally not hooked up, but if it is, it doesn't raise IRQ. Also delete unused G65816_INT_* macros (g65816\g65816.cpp).

- MAME
  . VIDEO RENDERING SYSTEM
    . Polygon rendering: Added dpdy information to extents to be able to compute mipmap lod index per pixel. Fixed portability issues in round_coordinate. Fixes severe graphical glitches in Namco System 22 games on ARM systems (video\poly.h) (ID 09276).
    . Removed most specialisations of the RGB utilities. Added an ARM NEON bilinear filtering implementation. Increased the intermediate precision of the C++ bilinear filtering implementation. Cleaned up and fully inlined the C++ implementation apart from bilinear filtering. Moved the generic C++ implementation to emu\video\rgbutil.h. Put all bilinear filtering implementations out-of-line in emu\video\rgbutil.cpp.
  . MEMORY SYSTEM
    . Fixed debugger's memdump command. Changed memdump to properly report overlapping views (emu\emumem.cpp, emu\emumem_hedr.ipp, emu\emumem_hedw.ipp).
  . INPUT
    . Removed the "optional" field flag (emu\ioport.h). There are multiple issues with this flag: It's poorly defined. Is it an input that's software-accessible but not used? Is it an input that shows in test modes but doesn't do anything useful? Is it an input that the system can be configured to not use? Is it an input that is useful but not strictly necessary? In almost a decade, it hasn’t been used widely. It was used in less than ten places. There hasn't been substantial interest in actually applying it across the codebase. It would be an absolute nightmare to try and apply to mahjong and hanafuda games. Consider all the cases where a game may use some but not all of the double-up game controls, and some games support multiple control schemes that use different subsets of the standard mahjong matrix. Trying to apply it to gambling systems would also be a minefield. If we were to expect it to be applied, it would cause an eplosion in input port definitions for platforms with multiple games, adding further maintenance burden. It would greatly reduce the value of having things like the standard mahjong panel definitions as you'd rarely actually be able to use them as-is.
    . Removed PORT_ROTATED from the core. This automatic joystick remapping feature has not been enabled in any driver for years (emu\inputdev.cpp, emu\ioport.cpp and mame/luaengine_input.cpp).
  . LUA engine: Allow configuring analog input adjustments from scripts. Export minvalue and maxvalue for IPT_ADJUSTER (mame\luaengine_input.cpp).
  . 3RDPARTY: Sync AsmJit with upstream version 1.20 from https://github.com/asmjit/asmjit/commit/5134d396bd00c1b63259387acdbb12dfdf009f9b (3rdparty\asmjit).
  . Prevent automatic attempts at loading or creating loose image files with the same names as extant software list items when they fail to load as such. Only allow command line image creation when file is not found and save startup image name for error reporting before trashing it (emu\image.cpp).
  . Updated Chinese (Simplified) translations. The revision refers to the Windows 11 Chinese Simplified menu buttons and option titles, many places are still not perfect, modify it again and again! (Chinese_Simplified\strings.po).
  . Doc: Fixed a typo in the documentation for the default values for the 'comm_localport' and 'comm_remoteport' flags: 15122 -> 15112 (docs\source\commandline\commandline-all.rst).
- Debugger
  . Fixed parsing of unary ! operator in debug expressions (debug\express.cpp)
  . Added support for generating PDB symbols with MinGW Clang and LLD. Also don't disable sibling/tail call optimisation when symbols are enabled. This is hurting our release builds since they're built with symbols. Note: Set PDB_SYMBOLS to 1 to generate CodeView format symbols in separate PDB files, allowing source-level debugging using Microsoft Visual Studio or WinDbg. It can also be used with other tools that can load symbols from PDB files, e.g. the Intel VTune and AMD µProf performance analysis tools. This option is only supported for MinGW builds using the clang compiler and the LLVM linker (lld). This option only takes effect if the **SYMBOLS** option is set to a non-zero value (makefile, scripts\genie.lua, src\main.lua and scripts\toolchain.lua).
  . Fill q.value was not working (debug\debugcmd.cpp)

- CPU
  . ARM7: Removed the recompiler that had never been completed (arm7\arm7.cpp)
  . Dynamic Re-Compiling
    . drcbec: Improved behaviour for float-to-int conversion. Apply floating point rounding mode to arithmetic (cpu\drcbec.cpp).
    . drcbex86: i686 has no red zone (cpu\drcbex86.cpp)
    . drcbex64
      . Slightly optimised flag calculation for some variants of the multiply instructions (cpu\drcbex64.cpp).
      . Fixed some cases where GETFLGS would produce incorrect results when the destination is not a UML register permanently assigned to a host register (cpu\drcbex64.cpp).
    . drcbearm64
      . Added missing source load for optimised ROLINS case. Fixes bad ROLINS results in some cases where the result is in memory. Hopefully fixes Hyperstone E1 systems corrupting SR on absolute jumps (e.g. kdynastg failing to boot) (cpu\drcbearm64.cpp).
      . Optimised shift and rotate operations. Don't calculate carry flag when not requested. Don't calculate zero and sign flags when only carry is requested. Avoid branches when calculating carry, optimise for non-zero shift. Improved strategy for selecting working registers (cpu\drcbearm64.cpp).
      . Implemented float-to-int conversion using rounding mode. Also optimised code generation for UML ROL (rotate left) and slightly optimised carry flag calculation for left shift (save one instruction) (cpu\drcbearm64.cpp).
      . Added NEON vector register assignments to the header comment (cpu\drcbearm64.cpp).
      . Fixed some cases of 32-bit operations not clearing the upper bits of a UML register (there are still a few remaining). Optimised unordered flag test - only the V bit needs to be tested. Fixed rounding mode dispatch for FTOINT (cpu\drcbearm64.cpp).
      . Apply floating point rounding mode to arithmetic (cpu\drcbearm64.cpp).
      . Improved code generation a bit: Avoid unnecessary operand loads for add/subtract operations where both sources are identical. Improved code generation for rotate through carry with immediate shift count and/or immediate zero source (cpu\drcbearm64.cpp).
      . Improved emulated memory access code. Generate optimised code for reads narrower than native width. Mask returned value to access size - the upper bits may not be cleared (fixes Hyperstone E1 misbehaving on Windows arm64). Don't save emulated flags across CALLC - flags are clobbered anyway (cpu\drcbearm64.cpp).
      . A few more optimisations: Avoid some unnecessary register copies for the displacement in LOAD/STORE when the scale is 1. Avoid unnecessary register copies for ROLAND when the source is a UML register kept in a host register. Avoid an unnecessary register copy for ROLINS when inserting a left-aligned field (cpu\drcbearm64.cpp).
    . UML
      . Added a couple of simplification rules. ADDC's inputs are commutative and TEST with an immediate zero operand effectively ignores the other operand. Got rid of a redundant assignment (cpu\uml.cpp).
      . Added simplification rules for FFRINT and FFRFLT (cpu\uml.cpp). Added a simplification rule for pathological cases of SEXT (cpu\uml.cpp). Added some simplification rules for multiply and divide (cpu\uml.cpp).
      . Fixed potential assertion failure when a degenerate rotate through carry is converted to a move (cpu\uml.cpp).
    . drcumlsh
      . Removed helpers for generating the unimplemented JMPH instrcution. Trying to use it would cause a compile error (cpu\drcumlsh.h).
      . Use "src" rather than "src1" if there's only one source operand (cpu\drcumlsh.h).
    . Doc
      . Documented the most common DRC UML integer arithmetic and logical instructions. Documented some UML floating point arithmetic instructions. Also replaced mathematical symbols for Boolean algebra with less desirable C operators as they were upsetting pdflatex (docs\source\techspecs\uml_instructions.rst).
      . Documented more DRC UML floating point instructions (docs\source\techspecs\uml_instructions.rst). Documented several DRC UML shift/rotate instructions (docs\source\techspecs\uml_instructions.rst). Documented the DRC UML SEXT instruction (docs\source\techspecs\uml_instructions.rst). Documented the DRC UML integer multiplication and division instructions (docs\source\techspecs\uml_instructions.rst).
      . Documented DRC UML rotate through carry instructions (docs\source\techspecs\uml_instructions.rst).
- SOUND
  . Konami 053260 KDSC: Added TODO about reverse-engineered pan LUT. The pan LUT is mentioned in the reverse-engineered based on work by Furrtek: https://github.com/furrtek/SiliconRE/blob/master/Konami/053260/k053260_schematics.PDF
  . Sega 315-5313 Megadrive VDP: Acknowledge irqs only if enabled. Fixes regressions with (MESS) chukrck2 & d_titov2. Delay VINT regular triggers. Fixes (MESS) mazinsagj hang regression (video\315_5313.cpp/h, hash\megadriv.xml).
  . SN76496: m_sega_style_psg was wrong way around. Fixed recent regression with initial period. Fixes megatech.cpp games have a loud noise in one of the sound outputs (ID 09258). Whitespace cleanup. 'ready state' variable was missing from savestates. Initial volume is 0xf on Sega PSG. No need to savestate volume table. Only write ready pin devcb if ready pin changed, no need for in_noise_mode function and added pinout diagram to h file (sound\sn76496.cpp).
  . Yamaha YMF271 OPX: Update stream before reading status registers and fixed a performance regression (sound\ymf271.cpp). Note: Performance regression was from MAME 0.195 (Allow 4 channel output...). It was clearing the complete mix buffer at each stream_update, instead of only clearing amount of samples, making seibuspi driver boot-up sequence about 2.5 times slower.
- DEVICE
  . Flash ROM: Added SST_39SF020 and fixed sector size for SST_39SF0*0 (machine\intelfsh.cpp)
  . Floppy/PC Harddisk
    . Allow images loaded from software lists to be write protected (imagedev\floppy.cpp). Set m_mon to 1 (motor off) in constructor (imagedev\floppy.cpp). Fixes (MESS) mtu130 crashes MAME, if you try to load a software-list item that is missing (ID 09005). Fixes (MESS) LSI m3 crashes when attempt to use missing disk (ID 09255).
    . Basic fix for pc_chd support in imgtool. Take ownership of stream in pc_chd_image_open. 'imgtool::image::internal_open' passes an rvalue reference to the stream to the 'open' function of the image format module. It expects the 'open' function to take ownership if it keeps a reference to the stream. If 'open' does not do so, the 'stream' is going to be destroyed at the end of 'internal_open'. 'pc_chd_image_open' fails to take ownership, yet it persists a reference to the stream as part of 'info->hard_disk'. This causes an use-after-free condition. Correct determination of total sectors of a FAT volume. The number of total sectors of a FAT volume is stored either in the 16-bit word at offset 19 or, if that word is zero, in the 32-bit word at offset 32 instead. The 32-bit word is not a high word to build a 48-bit value in conjunction with the 16-bit word at offset 19, but it supersedes it (modules\fat.cpp and imgtool\modules\pc_hard.cpp).
    . Correct recalibrate steps for Intel N82077 FDC. As documented in the datasheet it should be 80 for this FDC (machine\upd765.cpp). Recognize more file types (formats\fs_prodos.cpp).
    . Added a default implementation for 'supports_save'. Since the default implementation of 'save' is a stub that always fails, it makes sense to also add a default implementation of 'supports_save' that returns 'false'. That way, there's one fewer method that needs to be implemented for read-only image formats. Removed the now-redundant implementations in concrete format classes (formats\flopimg.cpp).
  . I2C Memory: Fixed (MESS) later Acclaim sport games fails I2C checks during POST (sega\megadriv.cpp) (GitHub #13998)
  . Intel 8251 USART: Don't do binary math on bool. Removed unneeded calc_parity function (machine\i8251.cpp).
  . Intel 8256AH Multifunction microprocessor support controller: Added Intel 8256 MUART. Don't do binary math on bool. Removed unneeded calc_parity function. Small cleanup (machine\i8256.cpp).
  . Konami 001006 Texel Unit: Fixed save state support. Added save state registration and fixed initialization for bilinear flag. Use fixed sized integer for device selection (konami\k001006.cpp).
  . Konami 007121 Video Controller: Use callback for sprite color bank/code bank and moved global x offset into configuration. Renamed set_spr_dx to set_sprite_offsets similar to how these displacement functions are named on other konami chip devices (konami\k007121.cpp).
  . Konami 053936 PSAC2 tilemap generator: Reduced duplication and added notes about emulation deficiencies. Updated notes based on reverse-engineering by Furrtek. Also cleaned up code (video\k053936.cpp).
  . Konami 056832 Tilemap Generator: Removed duplicate function
  . MagicEyes VRender0: Updates and cleanups (machine\vrender0.cpp)
  . MOS 6522 VIA: Changed timer1 count=0 change from MAME 0.277 to only when in continuous mode (machine\6522via.cpp). Fixes several Vectrex games hang MAME (ID 09249).
  . National Semiconductor INS8250/NS16xxx UART: Avoid setting data frame when bit encoding doesn't change (machine\ins8250.cpp)
  . SNK68 Sprites: Added flipscreen variable to savestates (other vars are configuration) (shared\snk68_spr.cpp)
  . Zilog Z80 DMA Controller: Clear BUSRQ line upon device reset to prevent CPU from freezing after a soft reset (machine\z80dma.cpp)
- 3x3puzzl.cpp: Moved videoram DMA out of screen_update
- alpha68k_n.cpp: Small cleanup to gamelist spacing. Only enable transparent color to Super Stingray. Fixes also kyros and kyrosj seems to have two graphical problems on the last level of the game (stage 5) (ID 01148).

  . VIDEO RENDERING SYSTEM
    . Use raw parameters for screen timings in exidy\carpolo.cpp and exidy\circus.cpp
    . Make hit test priority match visual order. Also made order of parsing view element more logical (makes interation with parameter elements less confusing). Some layouts have been updated, others still need work (emu\rendlay.cpp).
    . Do a 2-pass for updating artwork clickable zone input field state. Fixes Artwork held input is released after crossing overlapping clickable zone edge of same input field (ID 09252) (emu\render.cpp). No need to do std::transform here. Yoda style for loop like the surrounding source (emu\render.cpp).
    . Changed legacy marquee UI toggle to Marquees instead of a 2nd Backdrops (emu\rendlay.cpp). Removed invert flag from 7seg element and added inverted 7seg outputs to mpu4 (the only driver that used this flag) (emu\rendlay.cpp).
  . MEMORY SYSTEM
    . Optimize a specific but useful case (emu\emumem.cpp). Added forgotten range checks (emu\emumem_mview.cpp).
    . Avoid splitting handlers on dup-ing, avoiding tons of extra allocations (emu\emumem_hedr.ipp and emumem_hedw.ipp). Fixes MAME crashes with "Caught unhandled St9bad_alloc exception: std::bad_alloc" message in all quizdna.cpp sets (ID 09251).
    . Count references correctly for de-duplicated handlers (emu\emumem_hedr.ipp and emumem_hedw.ipp). Restrict 'check_optimize_all' to very short ranges (fixes crash in cave/cv1k.cpp games) and optimized the optimization further (emu\emumem.cpp).
    . Work around regression in Gaelco3D games by disabling optimization when address select is enabled (emu\emumem.cpp)
    . Prevent subunit offsets from being masked out in handlers (emu\emumem_mud.cpp). Fixes sound in suprnova.cpp. Short-term fix to some crashes, need more thinking though (emu\emumem_mud.cpp).
  . DEVICE: Avoid updating data frame if nothing changed. Don't use bitwise OR on bool. Small cleanup to spacing (emu\diserial.cpp).
  . INPUT: Fixed "Application" key with SDL keyboard provider (input\input_common.cpp). Also improved support for rare higher F-keys with SDL and Win32 providers.
  . UI/OSD: Hold ALT to INC/DEC setting by 100 (ui\analogipt.cpp)
  . SOFTWARE LIST: Split multiple languages/developers into separate info elements in all software lists
  . NETWORK: Added packet logging helper (emu\dinetwork.cpp)
  . Multi-Language: Updated Japanese translations (Japanese\strings.po). Added Polish translation (Polish\strings.po).
  . Consolidate drivers into single files (bking.cpp, gaiden.cpp, jack.cpp, rohga.cpp and senjyo.cp). Got rid of some VIDEO_START macros (rohga.cpp, gottlieb.cpp and docastle.cpp). Removed some unused/unneeded MACHINE_START / MACHINE_RESET / VIDEO_STARTs (cps2.cpp, scramble.h/_m.cpp, m92.h, model2.h, system1.h, route16.cpp, superqix.cpp and toaplan1.h)
  . Tidied some stuff (video\upd7220.cpp, atari\atarisy2.h, igs\igs017.cpp)
- Compiling
  . Fixed pull_request property (.github\workflows\includeguards.yml)
  . Fixed missing EoF marker (lib\netlist\build\create_lib_entries.py)
  . Don't pass --line-numbers to objdump. It has no effect on --syms for GNU objdump, but it causes LLVM objdump to disassemble the executable (scripts\src\main.lua). Improved support for building on Windows arm64. Manage objdump processes from python. Avoids issues with inconsistent shell behaviour (dist.mak, scripts\build\llvm-objdump-filter.py, scripts\src\main.lua and scripts\src\osd\modules.lua).
  . Fixed compile with Clang 21.1.1 (machine\spg_renderer.h, tvgames\generalplus_gpl162xx_lcdtype.cpp)
- Debugger
  . Extended memory commands for region and space (emu\debug\*). Reduced unnecessary duplication (debug\express.cpp).
  . Don't persist fallback expressions (debug\debugvw.cpp)

  . SN76496: Tone frequencies and volume are non-zero at startup (gives (MESS) BBC Micro boo-bip startup tones) (sound\sn76496.cpp)
- DEVICE
  . Floppy: Prevent INTRQ from being raised until last DRQ is serviced unless data was already lost (ID 09236). Fixed validation by restoring wonky difference between ISA8 and ISA16 option lists (machine\wd_fdc.cpp).
  . ISA: Merged ISA8 options with ISA16 8-bit options, i.e. allow mounting (MESS) IBM Speech to ISA8, xtide to ISA16 (isa\isa_cards.cpp).
  . Konami 053244/053245 Sprite Generator: Small cleanup (konami\k053244_k053245.cpp)
  . Konami 053260 KDSC: Uses K053260's TIM2 output as interrupt source (sound\k053260.cpp). Small optimization to devcb.

- astrcorp.cpp: Added dedicated inputs for keno21 and gostopac
- bankp.cpp: Cleaned up a few things
- btime.cpp: Merged driver with scregg.cpp
- cdi.cpp: Added Interlace Graphics (GitHub #13997). Doubles vertical resolution. Minimal code to double the vertical resolution for GitHub #13231. The result is a slightly crisper looking image on most monitors due to better upscaling on images are have less oblique pixels. This was tested minimally and seems stable. Something closer to a proper interlaced image can be accomplished using the _PA bit, however current screen blanks between frames preventing the parity bit from being able to produce a correct interlace image yet. Removed excess vertical resolution. Use 2x clock multiplier. Added Interlaced Graphics. Fixes GitHub #13231. Toggle interlace effect. When the interlace bit is off, line-duplication is re-enabled. This ensures the interlace effect is only visible when the game declares the output to be interlaced. Fixed interlaced line offset. In some cases, such as during startup, the line length of the interlaced line is impacted. This corrects the offset. Fixed interlace clock speed (philips\mcd212.cpp). Cleaned up a few more things (philips\mcd212.cpp).

- Bob Zed (What's new): https://youtu.be/EXg3sKss5Og
- CPU
  . Hitachi SH-2 (SH7604): Hookup UBC BARA/BARB r/w (sh\sh7604.cpp), fixes sound in (MESS) 32x aburner.
  . Motorola MC68010: 'ctor' accepts type param. Support being able to subclass and pass in type param (m68000\m68010.cpp).
  . NEC Vxx: REP opcodes are interruptable. Fixed issue with prefetch (can't do prev_icount - m_icount to determine opcode cycles since m_icount can be cleared externally) (nec\nec.cpp). Fixes incorrectly effects in 'Ninja Baseball Bat Man' (ID 06021) and the status bar in Battle Chopper and clone appear twice (ID 00816). Fixes Major Title 2 and clones hangs at title screen if flip screen is enabled (ID 05342).
- SOUND
  . Atari C012294 POKEY: Synchronize on SOD output transitions during serial transmission. Disable logging again (sound\pokey.cpp).
  . Biquad Filter: Added calculator functions for RC-based band-pass filters (sound\flt_biquad.cpp)
  . Ensoniq ES5503: Fixed error in emulation of oscillator over-contribution glitch (GitHub #13669) and use m_ prefixes consistently. Oscillators halted by the CPU have the same behavior as those halted internally if the low bit of the mode is set, as per the datasheet. Fixes Skate or Die for the Apple IIgs's music freezing (sound\es5503.cpp)
  . Sony LDP-1450 HLE: Fixed display mode selection issue and grey background (machine\ldp1450hle.cpp)
- DEVICE
  . Floppy: Include IPF, 86F disk formats in floptool. IPF is included unconditionally by scripts/formats.lua, so the HAS_FORMATS condition was always false. 86F is also included unconditionally but simply wasn't added to formats/all.cpp when it was introduced. Added 86F to the "Container FM/MFM" category for consistency with the grouping in devices/imagedev/floppy.cpp and moved IPF to the "PC" category for the same reason (formats\all.cpp).
  . Fujitsu MB87030 SCSI controller: Fixed SCSI hookup in (MESS) FZ-20M (machine\mb87030.cpp)
  . I2C Memory: Revert change from MAME 0.278 (Don't enter start condition except from idle state) that broke dreamlss. Don't falsely register I2C bus start or stop condition while device as slave is driving SDA. Modernize logging (machine\i2cmem.cpp). Fixes bmiidx2, bmiidx3, bmiidx4, bmiidx5, bmiidx6, bmiidx7 and bmiidx8 fails to boot with "E800 NO SECURITY CARD ERROR" (ID 09212). Fixes BnB Arcade has severe slowdown, black screen in attract mode and unable to start game (ID 09220).
  . Konami 005849 Video Controller: Added preliminary k005849_device
  . Konami 007121 Video Controller: FIRQ is every other frame. Removed dirtytiles_cb (konami\k007121.cpp).
  . Konami 051960 Sprite Generator
    . Improved sprite y zoom. Fixes bad sprite zooming for the planes in Devastators level 2 (ID 00505). Added sprite buffer, fixes sprite lag in Aliens (ID 02014 and ID 06873). Added sprite busy flag and irq enable. Removed old #if 0 spriteram savedump.
    . Improved NMI timer and sprite busy duration.
  . Konami 052109 Tilemap Generator: Added screen raw params to all K052109 drivers. Added col+rowscroll, fixes possible graphical corruption during stage 2 in Thunder Cross II and clones (ID 08275). Added NMI and FIRQ timers (copy paste to/from k051960). Added callback for custom scrolling to emu\tilemap.cpp and added one to K052109 for its combined col/rowscroll. Update scroll before active display (konami\k052109.cpp).
  . Konami 053244/053245 Sprite Generator: Removed old #if 0 spriteram savedump. Moved sprite buffer clear to reg 7. Limit sprite size to 1024x512. Assume sprite size limit is cliprect, not zoom level (konami\k053244_k053245.cpp)
  . Konami 053250 LVC: Small cleanup (konami\k053250.cpp)
  . Konami 053251 Priority Encoder: Removed obsolete code (all dirty tilemap marking after colorbase changed is done locally in drivers). Removed unused read() function (konami\k053251.cpp).
  . Konami Custom: Correction to device strings (Konami 0xxx instead of K0xxx)
  . Sega 315-6154 Northbridge: Handle statuses and IRQ callback. Updated docs (sega\315-6154.cpp).
  . Z80 DMA Controller: Added UA858D DMA Controller variant to machine\z80dma.cpp. Added extra memory read wait state at 28MHz for (MESS) ZX Spectrum Next (machine\z80dma.cpp).
- aristmk6.cpp: Dumped SPC2 board rom gambs2m_01.05.07.u3 (SPC stands for serial protocol converter)
- astrcorp.cpp: Avoided completely patching out protection routines for a bunch of games, fixes some problems at start up and when exiting test mode. Reversed remaining CPU codes. Factory reset EEPROMs. Got rid of checksum/original ROM content related patches. Switched to mnemonic suffixes for clones. Metadata improvements and Q/A for most magibomb sets.
- badlands_ms.cpp and galpanic_ms.cpp: Added missing PLDs to clones Bad Lands (Modular System) and New Quiz (Modular System bootleg of Gals Panic)
- battlnts.cpp and rockrage.cpp: Use screen raw parameters as in similar Konami games. Added clocks for video ASICs.
- boramz80.cpp: Implemented NVRAM, hopper and protection workaround. Moved out of skeleton to misc. GFX problems remain, games are otherwise playable (tpkborama excluded, since it's encrypted).
- cave.cpp: Added hopper device. Fixes Crusher Makochan and Koro Koro Quest returns "Error 3" after completing a stage (ID 09223).
- cdi.cpp
  . Implemented cursor blinking (philips\mcd212.cpp). Fixed double width cursor. This fixes cursor width is too wide in The Challenge (GitHub #13968). Originally this flag made the cursor 2x as wide (4 pixels). However the Validation Disc (EU) test GC_Ptn has a clarifying comment that in double-resolution mode, the cursor should be half the width of the normal cursor (philips\mcd212.cpp).
  . Fixed Pixel Hold Clut4. Console verification identified a descrepency in CLUT4 pixel hold behavior. This corrects a factor of 2 error in the width for CLUT4 (GitHub #13513) (philips\mcd212.cpp).
  . Added Undefined Matte Behavior. Fixes GitHub #13976. Greenbook says not to change the MF flag within a line. However, if you do, the behavior is undefined. Console verification shows that the real console will use these values. The non-spec behavior is explained in a comment. Additionally, this tidies up the Matte function. Fixed RGB Transparency. This fixes RGB transparency checks. Previously it was checking the high bit. This would pass when checking the false condition (mode 10) but not on the true condition (mode 2) (philips\mcd212.cpp).
  . Fixed Cursor Inversion Color. This corrects a slight error in the cursor inversion color. A full brightness color should keep the brightness value and only invert the RGB. See MCD212 section 7.5 (philips\mcd212.cpp).
  . Introduce External Video Input. This replaces the static background color with a function that will switch behavior if the EV flag is set. Currently there is no DVC chip, so this will produce black output. This fixes (GitHub #13980) (philips\mcd212.cpp).
  . Simplified CD-i CDIC MCU. This simplifies the reference functions while making small changes to the used functions. Fixed CDIC XA audio header offset. Fixes Github #13991 (philips\cdicdic.cpp).
- circus.cpp: Set maincpu ROM_LOAD to 0x0. Fixes Robot Bowl hang/freeze at boot (ID 09225).
- cps1.cpp
  . Removed unneeded init function. Do interrupts with IPL pins and HOLD_LINE and copy over raster interrupts from cps2. Re-add cpu space map for irqack.
  . Correct the cpu space back to fully take into account the impact of vpa on the timings. Added debugger side effects check. Removed old TODO notes (one about raster effects and one about supposedly missing sf2 layers). Correct the cpu space back to fully take into account the impact of vpa on the timings.
  . Ganbare! Marine Kun irq4 is actually the same raster interrupt as on cps2 (it writes to the raster regs too). Comment out n/a button3 in Final Fight.
- cps2.cpp: Improved raster irq. Make sure to mask raster counter with 0x1ff. Correction to raster irq timing. Fixes Shuma Gorath super move raster effect is not working in Marvel Super Heroes (ID 09221).
- cps3.cpp, pluto5.cpp and luckgrln.cpp: Removed if(0)ed-out routines for dumping decrypted ROMs
- ddragon3.cpp: Lower overall volume. Added sprite size mask and wwfwfest sprite buffer trigger. Fixes Combatribes sprite player glitch (ID 07595) (GitHub #13986).
- ghosteo.cpp: evert I2C Memory change from MAME 0.278 (Don't enter start condition except from idle state) that broke dreamlss. Don't falsely register I2C bus start or stop condition while device as slave is driving SDA. Modernize logging (machine\i2cmem.cpp). Fixes BnB Arcade has severe slowdown, black screen in attract mode and unable to start game (ID 09220).
- goldstar.cpp: Fixed NVRAM regression for sets in wingco_state
- hikaru.cpp: Added 2nd AICA and 315-5881 encryption and fixed ROM layout.
- hummer.cpp: Hooked up decryption
- igs017.cpp: Fixed tarzan and starzan addrmaps. Fixes graphical or security error causes the appearance of a character that does not exist in the original game in jking200pr and all starzan dependents (ID 09193).
- konmedal.cpp
  . Inverted hopper sensor. Reorder dsw settings (left = less, right = more).
  . Promoted Slime Kun and Tsururin Kun to working
- m72.cpp
  . Tweak bg layer 2 transmask workaround. Improved tile priorities. Fixes graphic priority issues in bchopper and clone mrheli (ID 09205).
  . Do spritelist fill with push_back. NEC Vxx REP opcodes are interruptable, fixes status bar in Battle Chopper and clone appear twice (ID 00816).
- m90.cpp: Small cleanup (irem\m90_v.cpp)
- m92.cpp
  . Added sprite/video disable flags and put bootlegs on different hw in subclass. Updated flipscreen before screen update (irem\m92_v.cpp).
  . Updated dipswitches. Fixes Gun Force II has wrong difficulty setting "very easy", should be shown as "hardest" (ID 07725).
  . NEC Vxx REP opcodes are interruptable. Fixes incorrectly effects in 'Ninja Baseball Bat Man' (ID 06021) and 'Major Title 2' and clones hangs at title screen if flip screen is enabled (ID 05342).
- mainevt.cpp: Added missing watchdog
- megadriv.cpp: Fixed Megadrive version register incoherent (no TMSS ROM) (GitHub #13941).
- model1/2.cpp: Sort out register update priority (mb86233\mb86233.cpp)
- model2.cpp
  . Implemented proper lighting and improved "gamma" table. Stadium ads in Virtua Striker have the correct colors now. Do geo_parse even if frame was skipped. Removed the (void) func params from h file too. Revert frameskip workaround.
  . Actually fixed Super GT 24h and Over Rev reverses gas and brake activeness by default (ID 07445)
- namcos22/23.cpp: Removed duplicate romsets (or rather, only the embedded s/n differs)
- namcos23.cpp: Added point ROM auto-increment to Namco System 23. Improves Downhill Bikers and Race On! visuals.
- phoenix.cpp: Small cleanup
- pluto6.cpp: Added support for Freescale mcf5206e peripherals for Pluto 6 emulation. Cleaned up driver.
- senjyo.cpp: Star Force boardset has 4mhz and 12mhz xtals and copy paste screen raw params from bombjack (pace matches PCB video). Fixes rarely no sound on Star Force (ID 09200).
- stella8085.cpp: Re-enable games that were commented in 0.278 release
- taitotz.cpp: Use versions as printed on Taito's hard disk labels in descriptions
- tecmo.cpp
  . Lower YM volume in Gemini Wing and small correction to mcfg. Fixes OKI MSM5205 is quiet compared to the PCB and OST (ID 08785).
  . More accurate ADPCM addressing (no audible change).
- tmnt.cpp: Removed VIDEO_UPDATE_AFTER_VBLANK flag and changed joystick to 4way in Cue Brick

- MAME
  . VIDEO RENDERING SYSTEM
    . Removed unused (and not working) TILE_LINE_DISABLED flag, just use cliprect for something like that. Added col+rowscroll. Added callback for custom scrolling (emu\tilemap.cpp).
    . Small optimization to scroll cache (emu\tilemap.cpp)
    . Re-Added support for high priority shadows (emu\drawgfx.h + drawgfxt.ipp)
  . UI: Added shift/ctrl/alt modifier keys to some controls (ui\viewgfx.cpp)
  . INPUT: Added coinage settings 10C_1C, 1C_10/20/25/50/100C (emu\ioport.cpp)
  . New sound infrastructure
    . Added full/channel route via menu instead of f/c keys (ui\audiomix.cpp). Moved notch filter check to ui (audio_effects\filter.cpp and ui\audio_effect_filter.cpp).
    . Put devtag in add ful/channel menu entry. Added not initialzed message when entering menu too early (eg. pressing tab on the red warning screen) (ui\audiomix.cpp)
    . Clamp final output to -32768, 32767 (emu\resampler.cpp). Fixed problem when default devices are missing (emu\sound.cpp), fixes Portaudio error when WASAPI is enabled with no audio input devices in the OS (ID 09192).
    . Don't repeat default settings at several places and removed unneeded float<->double conversions (emu\sound.cpp). Round default q down instead of up (probably has no audible effect) (audio_effects\eq.h).
    . Fixed initial -volume setting (emu\sound.cpp). Use emplace instead of emplace_back when reconfiguring mapping (emu\sound.cpp), fixes cursor highlight issue in Audio Mixer menu (ID 09204).
    . Finer control over HQ resampler settings (keeping max settings same as before) (emu\resampler.cpp and ui\audioeffects.cpp). Safety check for filter len (emu\resampler.cpp).
    . Correction to input gain calc. Increase max input db so input gain won't distort the signal. Re-added infinite release option and also infinite ratio. Added a header to advanced settings (audio_effects\compressor.cpp).
    . Misc sound fixes (emu\sound.cpp)
    . Sound modules
      . PortAudio: Re-add printf list of found devices with -verbose and added a check for duplicate device names (ID 09195). Can use unordered_map instead of map (sound\pa_sound.cpp)
      . SDL: Fall back to 2 channels if 0 channels are detected on a device (sound\sdl_sound.cpp)
  . Correct various games SN76489/SN76489A/SN76496 type based on PCB photos and/or schematics (appoooh.cpp, bankp.cpp, circusc.cpp, exedexes.cpp, hyperspt.cpp, ikki.cpp, mrjong.cpp, pingpong.cpp, senjyo.cpp, suprloco.cpp, tp84.cpp and trackfld.cpp)
  . Added PLDs to several Modular System games (Blood Bros. (Modular System), Euro League (Gaelco bootleg, Modular System), Power Spikes (Modular System), Splash (Modular System, ver. 1.0, checksum 16EDD8FB, non North America, censored), Splash (Modular System, ver. 1.0, checksum A6C431A4, non North America, uncensored) and Toki (Modular System)).
- SDLMAME: Testing for glibc does not guarantee pty.h is available. It's possible to build glibc for targets where its PTY wrapper functions are not implemented (osd\modules\file\posixptty.cpp).
- Compiling
  . Added SN76496 to scripts\target\mame\tiny.lua
  . MinGW/MSYS2 mktime() cannot handle dates before the Unix epoch, so use a precalculated offset between the Unix and MacOS epochs
  . Prevent excessive link times with the default optimization level for emscripten build (scripts\genie.lua)
  . Removed Wayland-EGL-backend requirement at compile-time. Since MAME 0.274 Wayland is dynamically loaded at run-time (scripts\src\3rdparty.lua).
  . Fixed LZMA PPMD support (src\3rdparty.lua)
- Debugger
  . Requiring every debugger window class to care about the console window's views is bad design. That's a clear case of unnecessary coupling (debugger\win\*).
  . Used DCA_SELECTED color friendly for Light/Dark theme (qt\debuggerview.cpp)
  . Do not drop into debugger when no MAME window has focus. On Windows, the debugger has a special Windows-specific feature that drops the user into the debugger if the key sequence is pressed. This seems to be present so that the key sequence triggers dropping into the debugger not just from the main window, but also from debugger windows. This has also created an oddity where pressing the debugger key sequence from a MAME window will cause a "User-initiated break" but pressing it from a debugger window will cause "Internal breakpoint" to be displayed. However, while this logic has a check to not apply when to a MAME window, it seems to also activate even if MAME itself is not in focus. This change ensures that a stray debugger sequence in a completely unrelated application won't cause the user to be dropped in the debugger (debugger\debugwin.cpp and win\debugwininfo.cpp).
  . Have print command insert spaces between numbers (debug\debugcmd.cpp)
  . Fixed symlist default CPU: When executed with no parameters, symlist was displaying the symbol tables for the first CPU and the debugger built-in globals. Defaulting to the first CPU like that didn't make sense. It now displays the symbol tables for the VISIBLE cpu and the debugger built-in globals (debug\debugcmd.cpp).
