* Support Colecovision Megacart.
Assume that a rom file that is more than 32K in size is a megacart
and that it should be bankswitched using Megacart protocol.
* Put megacart functionality in its own cartridge type.

Novation BassStation Rack Analogue Synthesizer Module [DBWBP]
Novation Drum Station [DBWBP]
Novation Super Bass Station [DBWBP]
Add disassembler and skeleton CPU device for Panasonic MN1880 architecture [AJR]
Factory elements can now pass additional parameters to device
constructors. This makes the design of interface objects like analog
callbacks easier.
The change also allowed to remove some "deep" calls into the core from
the MAME interface in netlist.h
* mw8080bw: update 280zzzap audio API in preparation for netlist audio
This is only API changes, following the pattern used by cuavas within the
past year to update other games in mw8080bw.
* mw8080bw: new netlist audio implementation for 280zzzap
New netlist-based audio implementation for 280zzzap (280-ZZZAP, 1976),
derived from Midway game logic board schematic. The sound generally
matches that heard in videos of the machine, though the real machine
seems to have more bass and less treble. This may be a cabinet effect
or something else, such as a difference in component values.
Due to the number of complex components being emulated and the nature
of the circuits, this netlist adds a lot of overhead, but it's still
fast enough to run at greater than real speed on modern hardware.
With minor changes, this implementation should also support lagunar
(Laguna Racer, 1977); with somewhat more substantial changes, it
would also support sspeedr (Super Speed Race, 1979). Both of these
games use sound circuits based on those for 280-ZZZAP.
plists.h was splitted into plists.h, pmulti_threading.h and
ptimed_queue.h. In addition removed plists.h from a number of files it
wasn't used in.
Certain minor adjustment needed to be made for cuda toolkit 10.1 and
10.2.
- Memory references in expressions no longer default to the console's visible CPU if no device name was specified, except when entered through the console itself. Expressions in view windows now use the context of the currently selected device instead.
- The pcatmem debug command and similar qt mouseover function now produce an error message if the initial address translation fails.
Related internal changes (nw)
- The debugger_cpu class no longer interprets memory accesses. The existing routines have been moved into symbol_table (which used to invoke them as callbacks), and reimplemented in most other places. Thecode duplication is a bit messy, but could be potentially improved in the future with new utility classes.
- The cheat engine no longer needs to hook into the debugger_cpu class or instantiate a dummy instance of it.
- The inclusion of debug/express.h within emu.h has been undone. Some debugging structures now need unique_ptr to wrap the resulting incomplete classes; hopefully the performance impact of this is negligible. Another direct consequence is that the breakpoint, watchpoint and registerpoint classes are no longer inside device_debug and have their own source file.
- The breakpoint list is now a std::multimap, using the addresses as keys to hopefully expedite lookup.
- The visible CPU pointer has been removed from the debugger_cpu class, being now considered a property of the console instead.
- Many minor bits of code have been simplified.
The last(?) two changes are:
- Add a template parameter to everything (theoretically the address
space width, in practice a level derived from it to keep as much
compatibility between widths as possible) so that the shift size
becomes a constant.
- Change the syntax of declaring and initializing the caches and
specifics so that they're embedded in the owner device. Solves
lifetime issues and also removes one indirection (looking up the base
dispatch pointer through the cache/specific pointer).
* Demoted Quizard and Quizard 2 sets to non-working.
* Started hooking up the Quizard MCU.
* Renamed CDI_SLAVE to CDI_SLAVE_HLE in prep for an LLE device.
* Added more comprehensive notes to the driver.
* Removed NO_DUMP cdic.bin as the CDIC is apparently not an MCU.
* Copied SERVO and SLAVE MCUs into cdimono1 set from cdi910 set and marked with BAD_DUMP.
For reasons unknown to me compile optimizations do not behave for
template code. If the implementation is in separate compile units, the
code compiles and performs.
This needs more attention since for certain compilers there is a
considerable performance degregation. It looks like this is only
triggered if too many variants are declared in one cpp file and the
compiler stops inlining.
Thanks to Aaron Giles who made me think about a different approach.
This is a rewrite from scratch for rom devices. It uses a generic
template to implement rom devices which is used together with a
description struct to define a rom device. This leads to highly
efficient code since all information is available at compile time.
This is also a step forward to support tristate outputs. All rom devices
covered by this approach have tristate or open collector outputs and
thus all code changes to support tristate outputs can now be made
consistently in one file.
* move i/o handlers to specific maps, untangle register array usage, to be completed
* Nuke duplicate I/O accesses, rename to iobus_r/w, make go_w to be an actual line
* Fix addqmod & subqmod modulo mask for DSP
* Refactor TOM to host CPU function, and fix GPU irq lv 3 when a GPU object is encountered. Fixes mutntpng and atarikrt booting
* Fix Jaguar irq line to 2, trusted
* Start reworking the blitter
* Relicensed to BSD
