NOTE: As of this release, we have two more major changes. These should

be the last "huge" changes of this dev cycle.

 

The most major change is the final retirement of the global Machine

pointer, which has been part of MAME for many years. Frankly, I never

thought we'd hit this point so quickly, so my hats off to Atari Ace

who helped push through the final round of changes needed to make this

happen finally. As a result of this change, it should be possible in

the coming year to finally write a driver that runs two full machines

simultaneously.

 

The second big change is that the CPUs are now full-fledged devices,

and participate like all other devices in the system configuration.

This is mainly an internal structural change, but in the end removes

some redundant code and behavior. In a future dev cycle, a similar

thing will happen with the sound cores.

 

Starting now, the focus for MAME will be to iron out remaining issues

and release a 0.129 sometime around the 1st of the year. Please keep

reporting bugs to MAMETesters as you find things.

Source Changes

--------------

Removed old cherrym driver (meant to be removed last time, oops).

[Aaron Giles]

 

Funworld.c improvements [Roberto Fresca]

- Added new set: Jolly Card (italian, encrypted bootleg).

No coins... Only remote credits. After nvram init, set the Payout

DIP to 'manual' to allow the remote credits mode to work.

- Created inputs from the scratch for jolycdib.

- Updated technical notes.

 

Made CPUs into proper devices. CPUs are now added in the machine

configuration just as any other device, and the standard CPU

configuration is performed via the inline configuration macros.

[Aaron Giles]

 

Changed cpu_type from an enumeration into a pointer to the CPU's

get_info function, very similar to device behavior. Updated all

drivers to #include the necessary header files for the CPU's they

reference. [Aaron Giles, Atari Ace]

 

Added function cpu_get_type() to return the CPU type. [Aaron Giles]

 

Changed several cpu_* functions over to the device_* equivalents,

specifically for get/set info and for reset. [Aaron Giles]

 

The device system now maintains a parallel list of devices based on

type and class, for faster iteration through all devices of a given

type or class. [Aaron Giles]

 

Cleaned up code that looped over CPUs via the machine->cpu array to

now loop using the type-based device list. [Aaron Giles]

 

Removed start/stop/reset/nvram functions from the device_config in

favor of grabbing them as needed. [Aaron Giles]

 

Cleaned up the generic interrupt_enable code to work with CPU devices

instead of numbers. [Aaron Giles]

 

Mapped the devtag_* functions to device_* functions via macros instead

of parallel implementations. [Aaron Giles]

 

Removed cpuintrf_init() which is no longer necessary. [Aaron Giles]

 

Changed a number of APIs in the system to accept running_machine,

address_space, or device_config types, in order to remove the use of

the global Machine variable. Removed the global Machine variable now

that it is no longer directly references. [Atari Ace, Aaron Giles]

 

Added the concept of device "owner", for devices owned by other

devices. [Aaron Giles]

 

Modified laserdisc players to walk back to their global device state

via the owner, rather than brute-force searching for the first

instance and hoping that is the right one. [Aaron Giles]

 

Finalizer update [poUzVdb90]

- converted to tilemap

- added flipscreen

- changed sound chip name from SN76496 to SN76489A

 

Made the concept of a "clock" native to devices. The clock is now

specified when the device is added, and the clock is available in

the device_config directly via device->clock. Updated all devices

that have a clock to specify it when adding the device, rather than

as part of their configuration. As part of this work, also created

device-specific _ADD and _REMOVE macros to simplify configuration.

[Aaron Giles]

 

Defined a generic device execute function callback, though it

is not used yet. The long term plan is that any device with an

execute callback will be scheduled along with the CPUs. Now that

CPUs are devices, their scheduling will be moved over to this

logic eventually. [Aaron Giles]

 

Changed various NVRAM devices to fetch their default memory region

from the device->region rather than specifying it in the

configuration. [Aaron Giles]

 

Moved device startup to *before* the DRIVER_INIT is called. This

is to allow the DRIVER_INIT to configure devices that have been

properly allocated. So far I don't see any negative effects, but

be on the lookout if something weird shows up. [Aaron Giles]

 

Rewrote the device iteration logic to make use of the typenext

field and the newly-introduced classnext field for iterating more

efficiently through devices of a given type or class. [Aaron Giles]

 

Modified the parameters of the stream_update_func callback. As part of

this work, macro-ized all the callbacks to STREAM_UPDATE, and added

the sound device as a parameter. [Atari Ace]

 

Cleaned up i86/i286/i386/nec/v30mz headers: [Aaron Giles]

* renamed i86.h -> i86priv.h

* renamed i86intrf.h -> i86.h

* consolidated i88intrf.h, i186intf.h, i188intf.h, etc into i86.h

 

Cleaned up many other CPU headers to move memory read/write macros

out of them, since they are inappropriate and should be prive to the

CPU core. [Aaron Giles]

 

Removed index and clock parameters from CPU_INIT function.

[Aaron Giles]

 

Some PIC8259 updates: [Wilbert Pol]

- Fixed operation of edge-triggered interrupts

- INT output line is now cleared when an IRQ is acknowledged

- Implemented basic OCW3 features

 

Fixed proms in boobhack. [robiza]

 

Decoded some graphics and setup some RAM in the Virtual Combat driver.

[Andrew Gardner]

 

Cleaned up device and sound interfaces to match the CPU interfaces

when handling strings. Namely, the generic get_info functions

allocate a temporary string and the device in question copies its

string to the target, instead of assigning a const char *. Updated

all device and sound cores to operate this way. [Aaron Giles]

 

Added the concept of a cpu_state_table, which is supplied by the CPU

cores and which describes all the register state accessible to the

debugger and other subsystems. The format of the table is such that

most data can be simply fetched from memory without the further

involvement of the CPU core, including the display of common formats.

Extensibility points are available for custom display and for

importing/exporting the data to intermediate variables for more

complicated scenarios. Updated the ADSP21xx, TMS340x0, i86, Z80, Z180,

and 8085 cores to use this. [Aaron Giles]

 

Removed the old debugger register list, which was never used. Replaced

it with using ordering from the cpu_state_table. [Aaron Giles]

 

Renamed REG_PC -> REG_GENPC, REG_SP -> REG_GENSP, and

REG_PREVIOUSPC -> REG_GENPCBASE. Updated a few spots that were using

these directly. Moved these definitions into the end of the register

area rather than leaving them outside which put them in a weird range.

[Aaron Giles]

 

More cleanup. Added address-space-specific constants for the various

bus width and shift CPU interface constants. Changed all the cores

to use them. [Aaron Giles]

 

Changed ADSP21xx cores to accept a configuration struct instead of

using set_info to specify serial port callbacks. Simplified the

ADSP21xx get/set info significantly. Removed support for only

including certain variants of the chips; they are now either all

supported or all unsupported. [Aaron Giles]

 

Memory view fixes: [Aaron Giles]

* Fixed bug that computed the wrong total size if the address

space was a full 32 bits

* Improved display to show unmapped memory with *s

* Disabled enumeration of disk and 0-length regions

 

Added PAL to arkgcbl. [robiza]

 

Added Country Girl to the Jangou driver,working with sound

[David Haywood, Angelo Salese]

- Fixed transparency pens in the Jangou driver (so removed the

GAME_IMPERFECT_GRAPHICS flag); [Angelo Salese]

- Added a kludge for Jangou Lady RNG,will be worked on in the future;

[Angelo Salese]

 

Added running_machine callbacks for the Amiga code. [Nathan Woods]

 

Updated sscope2 to use newly-dumped roms. [robiza]

 

Added running_machine parameters to the f3853 callbacks. [Wilbert Pol]

 

Added running_machine parameter to the callback in the sid interface.

[Wilbert Pol]

 

Removed MDRV_INTERLEAVE(x), which specified the minimum scheduling

quantum in terms of "frames" (a dubious concept now with multiple

screens and changing refresh rates). Replaced it with a new

MDRV_QUANTUM_TIME(x) which specifies the minimum scheduling quantum

as a time value. Time can be specified as HZ(x), NSEC(x), USEC(x),

etc. Updated all drivers to use this, assuming 60 was the frame

rate (this is not perfect but should work for almost all cases).

[Aaron Giles]

 

Changed MDRV_WATCHDOG_INIT_TIME(x) to automatically prepend

UINT64_ATTOTIME_IN_ to the parameter, ensuring there is no improper

use of this macro and bringing it in line with the MDRV_QUANTUM_TIME()

macro. Updated all callers. [Aaron Giles]

 

Added new MDRV_QUANTUM_PERFECT_CPU(x) to specify that the minimum

quantum should be enough to ensure that the specified CPU tag only

ever executes a single instruction at a time. This can be used to

explicitly require "perfect" synchronization for drivers that have

multiple CPUs with shared memory. Turned this on for the arknoid2

driver for now as a test (the interleave on that driver was already

very close to perfect anyway). [Aaron Giles]

 

Fixed some color issues in the goldstar.c driver [David Haywood]

 

Merged goldstar and lucky8 drivers. [David Haywood]

 

Improvements to ddragon3/shadfrce/wwfsstar/wwfwfest: [Mamesick]

- converted driver to be fully scanlines based using timers

- updated driver to new video screen raw parameters

- hooked up interrupts (ddragon3, wwfwfest)

 

Fixed Agress' title screen. [David VanVoorhis]

 

Fixed update_handler for the dsp56k and polygonet. [Andrew Gardner]

 

Improvements to the dmndrby.c driver. [Mike Green]

 

Continued rewrite of the Motorola DSP56k CPU core. [Andrew Gardner]

* Fixed flag calculation and sign extension for numerous ops.

* Added rnd, mpysuuu, and dmac ops.

* Fixed do loop behavior to skip empty loops.

* Added stack underflow exception handling.

 

Improvements to the skylncr.c driver: [Roberto Fresca, David Haywood]

- Complete reel support from the scratch.

- Full inputs, outputs & DIP switches from the scratch.

- Added new games.

- Updated technical and game notes.

 

Rewrote 8080/8085 interrupt handling so that it makes sense. Changed

callbacks to be specified in a config structure. Converted core to

cpu_state_table. Changed to a single HAS_808X define for both cores.

Fixed several drivers that used 8080/8085 interrupts in odd ways.

[Aaron Giles]

 

Converted warpwarp driver to raw video parameters. [Aaron Giles]

 

Fixe 'run to cursor' and 'toggle breakpoint' operations in the

debugger when dealing with CPUs that have shifted address spaces.

[Andrew Gardner]

 

Improvements to goldstar.c driver. [Roberto Fresca]

- Hooked the 3x PPI 8255 devices to chryigld and ncb3.

- Reworked the chryigld and ncb3 inputs based on PPI 8255 connections.

- Added the unmapped PSG sound to chryigld and ncb3.

- Some works on their machine driver.

- Some cleanups.
