util/bitmap.cpp, util/palette.cpp: Marked lots of things constexpr.
Bitmaps don't throw exceptions on allocation failure, they just become
invalid. Almost nothing in MAME actually checks for this.
emu/profiler.cpp: Abort if the profile stack overflows rather than
throwing an exception. This is a developer feature and if it overflows,
the code is broken. Calling a noreturn noexcept function generates less
code than throwing an exception, which adds up.
util/strformat.cpp: Traded away some unnecessary flexibility for more
compact code. The stream objects must derive from std::basic_ostream
now - they can't just be any old objects with the expected operators.
* emu: add defer_access() method, which is useful for keeping the cpu in a loop restarting the current
instruction to emulate waitstates.
* add HP82321A Basic Language Coprocessor
This adds support for the HP82321A Basic language coprocessor, which emulates a HP9816 system with a 68K cpu. See http://www.hpmuseum.net/display_item.php?hw=681 for more details and software to run on this card.
* Got rid of a few more unnecessary uses of simple_list.
* bus/amiga/zorro: Got rid of a pointer member that would make adding
save state support unnecessarily difficult.
* nichibutsu/cop01.cpp: Remove need to remove devices from machine
config.
* bus/hp9845_io: Added HP9871 printer.

This is the "horsehoe crab" game pad version of the Denpa Micom Soft
Analog/Digital Intelligent Controller System (the other version is the
desktop "cyber stick").
Mega Drive games only support this controller in analog mode (the
default). Digital mode is designed to be used for games on computers
with MSX-style controller ports that don't support analog controls.
Use a memory view to switching between Game Gear and Master System compatibility I/O space mapping. Got rid of most of the conditional code checking whether it's a Game Gear driver.
Got rid of the special Game Gear EXT port slot. It's the same thing as a Mega Drive controller/expansion I/O port with a different connector.
sega/mdioport.cpp: Added a variant for the Game Gear with the TH/PC6 interrupt latch, and added it to the Game Gear.
-cpu/avr8: Added minimal ADC support (in particular, ADC interrupts are
not implemented).
-sega/megadriv.cpp: 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.
-sega/sms.cpp: Untangled SG-1000 Mark III slightly.
- Added cards ETI Real Time Clock, ETI Sound Card, Microtanic Real Time Clock, TUG Combo Card, and TUG EPROM Storage Card.
mt6809: Fixed keyboard input, RALBUG commands now work, and promoted to working.
- Added support for FLEX and BBC Micro floppy formats.
spinveti: Replaced incorrect ROM to load at &F800.
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.
sega/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.
sega/megadriv_rad.cpp: Simplified code.
bus/sms_ctrl: Added an RS-232 adapter. Only sending from the console to
the attached device works so far, reception will have to wait.
- Make CC 90-232 serial/parallel interface an extension device
- Eliminate spurious custom Centronics interface from MO5NR (CC 90-232 is used with this model instead)
- Make RF 57-932 serial interface an extension device
- Make MD 90-120 modem interface an extension device (emulation still needs work)
- Make Midipak an extension device and completely rewrite emulation
- Make MEA8000-based speech interface an extension device
- Configure 1 MHz E clock for extension bus
- Add FIRQ & IRQ outputs from extension bus
- Expand extension I/O address range from $x7D0-$x7DF to $x7C0-$x7FF
- Clean up various bits of driver code
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.
sega/sms.cpp: SG-1000 Mark III has pin 7 of controller ports tied low -
indicate this to attached controllers (this pin became TH on the Master
System).
sega/mdconsole.cpp: Replaced controller emulation in the driver with
Sega controller ports. Also removed some vestigial code from the driver
base class.
sharp/x68k.cpp: Replaced controller emulation in the driver with MSX
controller ports.
bus/msx/ctrl: Added a Sega controller adapter device, supported by
X68000 software including chelnov and ssf2.
*bus/coco: Remove real-time clock and no-halt functions from Radio Shack floppy disk controller.
* bus/coco: Added Disto Super Controller II floppy disk controller that contains no-halt functionality
* bus/coco: Added "mini expansion bus" that the SCII uses for add on cards, and added slots to SCII and Disto RAM cartridges.
* bus/coco: Added Disto "Realtime Clock" MEB slot device (also includes a parallel printer interface).
* Copied or moved Bee Cards entries from msx1_cart.xml to msx1_bee_card.xml.
* Copied or moved SoftCard entries from msx1_cart.xml to msx_softcard.xml.
gameboy.xml: Changed default NVRAM fill for dbzgeki to 0xff - this will
cause it to treat the three save files as empty rather than starting in
a glitchy state.

New working software list items
---------------------
gbcolor.xml: New Super Color 145 in 1 (China) [taizou, Vas Crabb]
Allow cartridges to install themselves rather than putting accesses
through trampolines. Use memory banks even when they aren't installed
directly, as it exposes script bindings and declares intent.
Added support for MBC6 Flash, and MBC7 two-axis accelerometer and 128*16
or 256*16 serial EEPROM. Added basic support for Game Boy Camera image
capture (various M64282FP processing features are not implemented).
Improved MBC3 real-time clock emulation.
Added basic support for Hudson Soft HuC-1 cartridges (infrared I/O not
supported) and HuC-3 cartridges (real-time clock and infrared I/O not
supported).
Added full support for Vast Fame VF001 cartridges.
Separated Mega Duck flat and banked ROM cartridge types, and allowed
software list items to specify whether a cartridge has fixed and
selectable 16K banks or a single selectable 32K bank.
Added support for RAM sizes smaller than 8K that will be mirrored in the
0xA000-0xBFFF area. Implemented correct ROM mapping for sizes that are
not powers of two. Corrected size of MBC2 internal static RAM.
Added support for various hypothetical cartridge wirings, such as MBC5
with outer ROM banking for up to 128M, M161 and Wisdom Tree cartridges
with flat RAM, and MBC1 or MBC5 with fewer than the maximum number of
inner ROM bank lines used.
Fixed logo spoofing logic for many pirate cartridges, including Rocket
Games, Sachen MMC1 and MMC2, Sintax, Li Cheng, and Niutoude. Identified
fine bank mask register for GBCK003 board.
Added basic support for GBX format ROM images. Added heuristic for
detecting raw dumps of M161 cartridge images. Removed unreliable
unlicensed cartridge detection heuristics - these need to be
reimplemented in a better way.

-Moved some stuff out of misc and skeleton:
* Moved Innovative Concepts machines to their own project.
* Moved various things out of skeleton to existing company projects.
* added emulation of required/used AXC51 / AX208 extended operations
* added preliminary emulation of required/used AXC51 / AX208 features
* added support for many Monon specific features, such as the video controller
* most games are playable, those not requiring a card/badge scanner to function at all are promoted
* no music, as it's contained in a game specific MCU under a glob on each cart
Added SOURCEFILTER option to specify a driver filter file in your make
options, e.g. like make SUBTARGET=custom SOURCEFILTER=mydrivers.flt (or
put it in your useroptions.mak if you'll be using it a lot). It
functions more-or-less like SOURCES on steroids.
Changed the way system/device source file paths are displayed to suit
the new source layout better. INI file loading hasn't changed, that
still just uses the base file name.
Added overlooked trigger to src/bus.lua to include NES controller bus if
the NES zapper sensor is needed.
* Changed name of cards for slot selection to "mdc48" and "mdc824" as
they're unrelated to the later 8*24 GC card.
* Also cleaned up code substantially and got rid of artificial
differences between Display Card 4*8 and 8*24.
* Moved lists of NuBus and SE/30 PDS cards to a common place.
* Got some class declarations out of headers to reduce recompiles.
Factored CRTC and shift register out of Spectrum/8 and added to Spectrum
PDQ. Fixes video mode selection and resolution for Spectrum PDQ.
Implemented vertical interrupt position, stride, line offset and clock
source registers for Spectrum PDQ. Added a hack to work around line end
control not being understood. Also added save state support.
Slightly modernised the Macintosh Display Card (JMFB) device code.
Initialised some driver state class members that were causing System 7
to fail to see files. [Ivan Vangelista]

- Eliminated hosenkan device altogether (mapper 182). It is identical to sglionk (mapper 114).
First major step in splitting up machine classes in NEC PC98 family tree:
* Splits up derivative HWs into own state machine and files (pc98ha.cpp, pc9821.cpp and pc9801_epson.cpp);
* Adds a preliminary uPD4991a parallel RTC, used by pc98ha;
* Fix -26, -86, -118 C-bus sound board dips or jumper settings;
* Fix default sound card for pc9821 (-86) and pc9821ce2 / pc9821cx3 (-118);
* Adds preliminary MAD Factory Otomichan-kai C-bus sound board;
* Adds boilerplate code for C-bus installing board I/Os, avoiding the possible inconvenience of board(s) getting silently unmapped by other installed boards;
* Major refactoring of HW dip switches readouts, using required_ioports instead of scattering things around in PPI hooks;
* Extensive QA rundown, including research on missing features and undumped machines.
pc9801.cpp: Don't passthrough mouse irq frequency when cycle setting is setup too, fixes jastrike mouse input on options menu.
