- Use device_resolve_objects to resolve callbacks in output_latch_device (nw)
Note that this renaming is not just for human convenience; genie seems to get confused by modifications to a header called latch.h and decides to recompile everything involving gen_latch.h as well.
Implementation of 28F010 and family flash memory devices. These are not compatible with the JEDEC-standard flash command protocol implemented in intelfsh.
* Don't use device_serial_interface for transmit - it can't support sync modes, on-the-fly register updates, and other weirdness.
* Better modelling of 1-deep transmit queue.
* Better RTS/CTS behaviour.
* Completely overhauled interrupt logic - vectors should be correct for most async modes.
* Implemented different auto-reset receive errors in MPSC vs SIO.
* Implemented SDLC transmission including bit stuffing, transmit CRC, abort, and underrun/end-of-message behaviour.
Added an SDLC consumer device that logs SNA frame headers and data.
The analogue joystick is now emulated. Also fixed a few minor issues
with the memory map.
This also adds a generic Z80 dasisy chain device, for use in drivers
with non-Z80 peripherals.
These humble 16-pin logic devices were commonly used in 8-bit arcade games to control coin counters/lockouts, IRQ flipflops, graphics banking, slave CPU reset lines, discrete audio triggers, screen flipping, serial EEPROMs and much else. Over 100 drivers and a few bus devices have been updated to use the new implementation, and a great deal of research has gone into documenting the physical location of these devices on actual PCBs in the source. Write handlers have been provided for both orthodox and somewhat less conventional memory mappings.
Incidental to this update, coin counters and/or lockouts have been added to Atari System 1 games, Basketball, Gauntlet, Gyruss, Hana Yayoi, Hole Land, Jr. Pac-Man, Mahjong Sisters, Pooyan, Roc'n Rope, Squash, Thunder Hoop, Time Limit, Time Pilot '84 and many others. This also cleans up coin counter behavior in Sauro and Rally Bike.
(nw) The purpose of committing this change, which has been several months in the making, early in the 0.189GIT cycle will be to allow time for fixing potential regressions; I've fixed a number of drivers that lost sound from this for various reasons (hnayayoi.cpp having missing or garbage ADPCM was particularly painful, since the three games in that driver all work slightly differently), but I can't test all affected drivers exhaustively. @Tafoid, don't bother running automated screen capture comparison tests on this, as many drivers are now expected to have the screen flipped for the first few seconds after reset.
The core changes are:
* Short name, full name and source file are no longer members of device_t, they are part of the device type
* MACHINE_COFIG_START no longer needs a driver class
* MACHINE_CONFIG_DERIVED_CLASS is no longer necessary
* Specify the state class you want in the GAME/COMP/CONS line
* The compiler will work out the base class where the driver init member is declared
* There is one static device type object per driver rather than one per machine configuration
Use DECLARE_DEVICE_TYPE or DECLARE_DEVICE_TYPE_NS to declare device type.
* DECLARE_DEVICE_TYPE forward-declares teh device type and class, and declares extern object finders.
* DECLARE_DEVICE_TYPE_NS is for devices classes in namespaces - it doesn't forward-declare the device type.
Use DEFINE_DEVICE_TYPE or DEFINE_DEVICE_TYPE_NS to define device types.
* These macros declare storage for the static data, and instantiate the device type and device finder templates.
The rest of the changes are mostly just moving stuff out of headers that shouldn't be there, renaming stuff for consistency, and scoping stuff down where appropriate.
Things I've actually messed with substantially:
* More descriptive names for a lot of devices
* Untangled the fantasy sound from the driver state, which necessitates breaking up sound/flip writes
* Changed DECO BSMT2000 ready callback into a device delegate
* Untangled Microprose 3D noise from driver state
* Used object finders for CoCo multipak, KC85 D002, and Irem sound subdevices
* Started to get TI-99 stuff out of the TI-990 directory and arrange bus devices properly
* Started to break out common parts of Samsung ARM SoC devices
* Turned some of FM, SID, SCSP DSP, EPIC12 and Voodoo cores into something resmbling C++
* Tried to make Z180 table allocation/setup a bit safer
* Converted generic keyboard/terminal to not use WRITE8 - space/offset aren't relevant
* Dynamically allocate generic terminal buffer so derived devices (e.g. teleprinter) can specify size
* Imporved encapsulation of Z80DART channels
* Refactored the SPC7110 bit table generator loop to make it more readable
* Added wrappers for SNES PPU operations so members can be made protected
* Factored out some boilerplate for YM chips with PSG
* toaplan2 gfx
* stic/intv resolution
* Video System video
* Out Run/Y-board sprite alignment
* GIC video hookup
* Amstrad CPC ROM box members
* IQ151 ROM cart region
* MSX cart IRQ callback resolution time
* SMS passthrough control devices starting subslots
I've smoke-tested several drivers, but I've probably missed something. Things I've missed will likely blow up spectacularly with failure to bind errors and the like. Let me know if there's more subtle breakage (could have happened in FM or Voodoo).
And can everyone please, please try to keep stuff clean. In particular, please stop polluting the global namespace. Keep things out of headers that don't need to be there, and use things that can be scoped down rather than macros.
It feels like an uphill battle trying to get this stuff under control while more of it's added.
