- CPU
. ADChips SE3208: Added exception hook callback
. Hitachi HD647180X MCU: Fixed typo on port E read
. Motorola MC6809, Hitachi HD6309 and KONAMI CPU
. Removed tuple implementation used by the EXG and TFR instructions of the 6809, 6309 and Konami CPUs. It was unnecessary because fundamentally these are implemented with a single, 16 bit wide temporary register. Changed how the 6809 CPU processes the invalid 8 to/from 16 bit register combinations. Their behavior now matches actual hardware. I used page 66 and 138 of Darren Atkinson's 6x09 manual (https://colorcomputerarchive.com/repo/Documents/Books/Motorola%206809%20and%20Hitachi%206309%20Programming%20Reference%20%28Darren%20Atkinson%29.pdf) for reference. I also double checked with my own hardware (http://tlindner.macmess.org/?p=945). Checked for regressions using (MESS) CoCo + NitrOS-9, Aliens and 88Games.
. KONAMI CPU: CPU has internal /4 divider. Enable 'hd6309 native mode' (m6809\konami.cpp/h). Match indexed opcode timing with hd6309, fixed carry flag on LSRD & ASRD and looped shift opcodes indexed mode (m6809\konami.lst). Don't use m_opcode as a temp variable and no need for those safe_shift functions (m6809\konami.cpp). Added IMM_IM from hd6309.

- SOUND
. AY-3-8910A PSG: Added machine().describe_context() to some logerror
. RP2A03/X APU
. Updated stream before reading statusreg, fixes (MESS) nes [summer92] drum sounds play wrongly (ID 05996). Can no longer read from anything but status register (sound\nes_apu.cpp). Added RP2A03 soundcpu bus conflict to Donkey Kong 3 (ID 08520).
. Implemented frame counter interrupt. Fixes (MESS) nes [ajyureir] and nes [portopia] have no sound and nes [dquest and doordoor] locks up (ID 06186) (ID 07625) (ID 07658). Removed wrongly placed dpcm irq clear.
- DEVICE
. ADC0808 A/D Converter: Fixed logerror
. Floppy
. Clear data_irq in fifo_r/w. Also disable clearing data_irq in msr_r. Fixes (MESS) pc8801 Donkey Kong 3 (ID 07199). Clear wc if the found sector has the correct cyl in the address field (machine\upd765.cpp).
. Fixed floppy sound spin sample oob access (imagedev\floppy.cpp), fixes (MESS) Apple II memory access violation in floppy device sound emulation (ID 07974).
. Imgtool: Removed some unused functions (imgtool\stream.cpp)
. Intel 8259 PIC: Treat slave IRQs as level-triggered even when LTIM = 0
. K052109 Tilemap Generator: Changed invalid logerror m_maincpu->pc to machine().describe_context()
. Trident TVGA9000: Converted isa\trident.cpp to logmacro, override trident_set_video_mode in tvga9000_device, makes Paint 'N Puzzle to set a sane refresh rate.
. VGA
. Fixed Read Mode 1 target color for comparison. Fixes at least transparent pen sprite-like in (MESS) ibm5150:lombrall and ibm5150:intsocch and missing text in ibm5150:pcglobe sets.
. Preliminary implemention for line_compare in vga_vh_ega mode
. Yamaha V9938 VDP: Implemented V9958 registers 26 and 27 for graphic23 and graphic4 modes, fixes (MESS) FS-A1FX + Space Manbow choppy background scroll (ID 08466).
- cave.cpp: Added PLD dumps for Gogetsuji Legends and Power Instinct 2
- cham24.cpp, famibox.cpp, multigam.cpp, nes_arcade_bl.cpp, playch10.cpp and vsnes.cpp
. Improved behavior of OAM writes during PPU rendering (video\ppu2c0x.cpp). Noticeably improves (MESS) NES High Hopes demo.
. Use documented recommended default DIP switch settings for vsnes.cpp. Affects hogalley, smgolf, suprmrio, vsbball, vsgradus, vsgshoe, vssoccera and any clones. Made separate DIP switch settings for vssoccer and smgolfj, as their starting point values differ from other sets. Fixed incorrect Zapper-like trigger behavior and made gun alarm wire machine configurable.
. Added save state support and cleaned up code for cham24.cpp
. Cleaned up sprite RAM DMA trigger trampolines in all drivers
. Added separate gun trigger input to playch10.cpp
- cobra.cpp, hornet.cpp and nwk-tr.cpp
. Refactored JVS host code into a common device for Konami PPC400 series systems
. Implemented JVS for nwk-tr.cpp. Replaced JVS code and hooked up Windy2 I/O for Fighting Wu-Shu 2nd! (cobra.cpp)
. Rewrote GN676 LAN board emulation. Now passed boot checks and supports x76 security chip (konami\konami_gn676_lan.cpp) (ID 07241).
. Added variants for Thrill Drive, Racing Jam and Racing Jam: Chapter 2. Added Thrill Drive security chips.
. Improvements for Silent Scope and Teraburst: Implemented ADC12138 for Silent Scope board. Made the GN680 return gun controls for Teraburst (ID 00315). Added note about IRQ0 and IRQ1 bits in sysreg_w. Fixed regression causing Teraburst's gun I/O to fail boot test.
- decocass.cpp
. Added handcrafted BIOS C (UK) (single byte changed) because 'Nebula (DECO Cassette) (UK)' requires region C. Fixed bit error in cnebula tape image.

. Soundlatch modernization for Fire Shark. Set mcu unmap_value_high, fixes continue music keeps playing after you select yes in clone Same! Same! Same! (ID 08522). Quantum can be reduced after adding latch device.
- turbo.cpp
. Correct sprite priority (74148 decoder) for Buck Rogers. Fixes ship disappears behind the growing blue warp effect at the end of each stage, enemy ships are drawn behind the distant mountains at Round 1 Sector 7 and ship appears ahead of the mothership, instead of behind it, making targeting it difficult at Round 1 Sector 8 (ID 08513). Added configuration to select (upright) button machine or (cockpit) pedal machine. Corrected cabinet type DIP switch. Improved internal artwork score panel (layout\buckrog.lay).

- Mega Drive (hshavoc.cpp, megadriv_acbl.cpp, megaplay.cpp, megatech.cpp and puckpkmn.cpp)
. Added Mega Drive I/O port controller device (sega\mdioport.cpp). Adapted all Mega Drive hardware drivers to work with the new I/O port device and moved based Mega Drive 68k peripherals to a common address map function.
. megadriv_acbl.cpp: Added base machine configuration to attach an optional I/O port to the EXP port and moved some stuff to derived classes. Use more derived memory maps and fewer driver init functions.
. puckpkmn.cpp: Eliminated dependency on other Mega Drive arcade bootlegs. Cleaned up code, register local class member for save states and suppress side effects for debugger. Considering boards without the U6612 exist, assume it uses a Mega Drive II VDP clone with integrated FM sound.
. Further broke up base Mega Drive class. Created a light-weight base class with just the core functionality, used for "Genie" hardware (Puckman Pockimon). Moved built-in controller emulation to a derived class so it isn't lurking underneath the consoles with pluggable controllers. Moved the Sun Mixing Mega Drive bootlegs to their own source file - they're substantially different, not using the I/O blocks for input.
. Moved YM sound out of "core" Mega Drive state and made more devices required in "base" Mega Drive state. Made (MESS) Pico/Copera derive from "core" Mega Drive state so they aren't carrying unnecessary baggage (all it uses is the CPU and VDP).
. Turned controller ports into slots - no need to simulate controllers in the cartridge device (bus\megadrive\jcart.cpp).
. Simplified wired 6-button controller to use a single input port per pad (sega\megadriv.cpp)

- Parodius DA!: Fixed KONAMI CPU looped shift opcodes indexed mode (m6809\konami.lst), fixes Parodius DA! background in Level 7 & 9 does not move (ID 08531).
- Sprint 8: Cleaned up input code. Made the gear shift levers toggle inputs. This needs to be confirmed from a manual.
- Starship 1: Set thrust control to slow when not pushing button
- Thunder Ceptor: Correct cpu type. Let's default view to 2D mode for clone 3-D Thunder Ceptor II.
- Fixed rom names in bfm_sc2.cpp and exprraid.cpp
- Dipswitch fixes in crimfght.cpp, epos.cpp, hornet.cpp, mappy.cpp, neptunp2.cpp, sprint8.cpp, turbo.cpp and vsnes.cpp

- MAME
. VIDEO RENDERING SYSTEM: Fixed a crash when toggling fullscreen, fixes numscreens 2 followed by Alt-Enter crashes MAME in windowed mode (ID 08535). Check for a non-null renderer before issuing a draw request to the renderer (osd\windows\window.cpp).
. MEMORY SYSTEM: Fixed MAME 0.250 (Fixed range tracking when creating a subdispatch) broken memdump (emu\emumem_hedr.ipp and emumem_hedw.ipp)
. LUA engine: Removed the "type" property from system driver metadata. It's effectively deprecated.
. DEVICE
. Fixed wrong value when used with callexport in device_state_entry::format (emu\distate.cpp)
. Allow command-line creation for tapes/memory cards/printouts (imagedev\cassette.h, magtape.h, memcard.h and printer.h)
. Made image devices not request read access when creating files for write-only devices (emu\diimage.cpp)
. UI/OSD
. Load INI files for the 'empty' driver that runs under the system selection menu (frontend\mame\mame.cpp and mameopts.cpp)
. Don't magically substitute environment variables when opening files (osd\modules\file\posixdir.cpp, posixfile.cpp, winfile.cpp and winrtfile.cpp)
. Added option types for single and multiple paths. Substitute environment variables in values from defaults and INI files. Fixed overriden default option values from OSD (util\options.cpp).
. Removed hard-coded list of multi-path options (ui\dirmenu.cpp)
. Work around reevaluate_default_card_software trying to purge XXX_default values. Reword some comments (emu\emuopts.cpp).
. Clear BIOS option setting when reloading empty pseudo-driver to prevent spurious ROM loading errors for this and other drivers (frontend\mame\mame.cpp). Fixes running a NeoGeo game, causes MAME to display false warning in other games afterwards (ID 08292).
. Rationalised right panel behaviour: Removed the "default" state for the image tab where it would show different things for different types of machine - it just confused users. Remember the selected tab and image in the right panel. State for system selection menu is remembered across sessions. Last used state for software selection menus is remembered across sessions. Within a session, state is remembered separately for recently selected machines, similarly to the way filter selection is remembered. Fixed some focus order issues in the software selection menu (mame\ui\*).
. Fixed issue when copying options that don't carry values (util\options.cpp)
. Got rid of the check for "arcade" systems - it broke managing favourites for the slotted Neo Geo (ui\inifile.cpp).
. PLUGINS: Don't substitute environment variables in path options (plugins\*)
. SOFTWARE LIST: Give "slot_default" option values default priority rather than maximum priority, so command line option specifications can override these. Silently ignore software list-provided default options or values that don't exist in a particular system configuration (emu\emuopts.cpp).
. Reworked Sega Master System controller bus (bus\sms_ctrl\*). Rationalised interface, got rid of TH from the "pulled" lines, and extended to support output on all data lines. Renamed to be less specific as the same interface is shared by multiple consoles. Removed a lot of unnecessary indirection through I/O ports and multiple levels of inversion in peripheral emulation that was obfuscating the code. Made Rapid Fire Unit switches toggles so they can be assigned to controller buttons and switched on/off easily during gameplay. You can still see/change the current state in the Toggle Inputs menu if you don't want to assign buttons. Implemented idle timeout in Furrtek 4-player Master System adapter. Improved crosshair tracking in Graphic Board, added ability to raise/lower pen, and greatly cleaned up code. Fixed paddle controller when used with export consoles. Added 3-button and 6-button Mega Drive control devices.
. Fixed bug where copyInto failed to copy nodes (util\xmlfile.cpp)
. Consolidated drivers in single files. Minor cleanups (equites.cpp, silkroad.cpp, sshangha.cpp and tehkanwc.cpp)
. Multi-Language: Fixed some errors in Brazilian Portuguese translation
. Added preliminary guide for would-be contributors (docs\source\contributing\*). Expanded C++ guidelines following suggestions by P. Mackinlay.
- Compiling: #include shuffling (imagedev\harddriv.h, util\harddisk.cpp/h and imgtool\imghd.h)
- Debugger
. Improved session save/restore. Qt: Save expression for memory and disassembly views. Made command history behave more like Cocoa. Added expression history and made behaviour more like Cocoa. Refactored global notifications to use signals. Added missing override qualifiers in Qt debugger. Win32: Increased command/expression history size to 100 items. Cocoa: Save state of device info viewer windows. Hopefully fix undefined names in Cocoa debugger. Qt/Win32/Cocoa: Save command/expression history.
