- CPU
  . 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.
  . Ricoh RP2A03/G: Don't read from unmapped apu regs
- SOUND
  . RP2A03/X APU: Updated stream before reading statusreg. Can no longer read from anything but status register (sound\nes_apu.cpp). Added RP2A03 soundcpu bus conflict to Donkey Kong 3 (ID 08520).
- DEVICE
  . Floppy
    . Clear data_irq in fifo_r/w. Also disable clearing data_irq in msr_r (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).
  . 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 background scroll (ID 08466).

- 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
- exidy440.cpp: Zerofill more class variables (exidy\exidy440_a.cpp)
- highvdeo.cpp: Make blit_ram writeonly, fixes heap-buffer-overflow (ID 08488)

- toaplan1.cpp
  . Clean up coin counter/lockout handling. Correct Z180 cpu speed for Fire Shark and Vimana.
  . 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.
- zaccaria.cpp: Fixed cocktail mode. Small cleanup.
- zerozone.cpp: Added PCB infos and derived clocks from actual XTALs, pending measurements.
- AGEMAME
  . Encapsulated sampled sound board as a device
  . Got rid of duplication in non-video and video system drivers. Set sound output to mono to match the circuit schematics. Added Alarm tone circuitry.

- Operation Tiger: Fixed poly rom region size, fixes heap-buffer-overflow (ID 08500)

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.
