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
Code cleanup to better separate the following stages:
- parsing
- setup
- run
In addition preliminary native tristate support was added. Not yet
production ready, please don't use it.
- Add and hook up interrupt controller and timer
- Add keyboard support (HLE)
- Clean up and improve graphics handling
- Add initial cassette support (not working)
- Add centronics printer support
- Add beeper
- More info to dip switches
The two sources act as voltage sources, though noise may also be
injected as conductivy or current noise.
SYS_NOISE_MT_U: Mersenne Twister uniform noise
SYS_NOISE_MT_N: Mersenne Twister normal noise
nld_sys_noise is templated:
using NETLIB_NAME(sys_noise_mt_u) =
NETLIB_NAME(sys_noise)<plib::mt19937_64,
plib::uniform_distribution_t>;
Thus the approach is scalable. The implementation is state save aware,
and thus reproducible results are guaranteed.
An example use case is provided as well, see examples/noise.cpp.
* new WORKING machines
Millennium M505 Arcade Neo Portable Spielkonsole (Family Sport 100-in-1) [TeamEurope]
* new NOT WORKING software list entries
tvgogo.xml : Baseball (US) [Sean Riddle, David Haywood]
tvgogo.xml : What-A-Mole (US) [Sean Riddle, David Haywood]
* added internal NAND dump to didj [Sean Riddle, Clawgrip]
The device can be found in nlm_other.cpp.
Removed nld_ne566.*
Added SYS_SW, SYS_SW2 and SYS_COMP. These are single switch,
alternating switch and a analog comparator with digital outputs.
Renamed RES_SWITCH to SYS_SW.
Added example ne566.cpp in netlist/examples.
--------------------
MDT 60 Video Display Terminal [Bitsavers, AJR]
z29: Add skeleton for undumped keyboard; try (and fail) to make this work with the MDT 60 keyboard instead
z22: Separate driver (nw)
Changes:
- added known dump checksums of 1101 BIOS
- high-level emulation of GPIB disk devices
- partial implementation of DMA (currently ignores ACCRQ so devices must have zero latency in order for it to work)
- serial is now properly memory-mapped
- modem stub in order to make system properly ignore modem device
- it now boots without any patches and debug scripts
- merged #6597 (needed in order to make disk devices work)
Still not implemented:
- RTC/MACHINE_ID
- modem
- has problems with multiple disk devices working simultaneously (possibly BIOS bug because this BIOS had some problems with that on real device)

Mastery's Fury [Miso Kim, David Haywood]
(this is a bad dump, mask ROMS are half size, at least the sprites)
new WORKING machines
----
Goori Goori [Miso Kim, David Haywood]
* Initial refactor of AVI/MNG movie recording, consolidation of copy and paste
code, hiding of AVI/MNG behind interfaces
* Extracted recording specific code out of src/emu/video.cpp and put into
src/emu/recording.cpp
* Took the opportunity to move slightly more logic out of video.cpp into
recording.cpp
* Bug fix
* Consolidated frame counting logic
- Use generic latch devices for sound communications
- More accurate handling of programmed sound resets
- Add the other LS259 to gauntlet.cpp
- Correct watchdog timeouts for all three drivers
- General code cleanup
atarigen: Eliminate ATARI_CLOCK_xxxMHz macros in favor of standard XTAL constants (nw)
atariscom: Separate source file from atarigen.cpp; move IRQ handling to atarijsa (not a property of the actual device) (nw)
