Subject: Another 8080/85 change from me
Hi Aaron,
I have noticed that there are some problems in interrupt handling in 8080 implementation. Thing is that there are some cases that made a problem while implementing one
computer emulation. Thing is that there is same computer with Z80 and 8080 cpu and ROM's are same, but interrupts were not triggered. So I have searched and found
two problems fixed with this patch.
1. previous implementation cleared interrupt enable bit on interrupt trigger which is wrong since interrupts should stay enabled
2. serve interrupt number was not cleared after interrupt is executed, so if same one is triggered it will not be catched.
I have tested with 8080 MESS drivers, and picked some of MAME drivers using 8080 and 8085, and there were no bad things found.
Regards,
Micko
recent cpu core changes. Specifically, it adds a fake device
implementation similar to the one the cpu cores were using in 128u3
(i.e. it only provides the machine pointer and the token), and makes
some interface adjustments aligned to 128u4 (i.e. adding
snd_class_header, adding get_ to various getter functions). The
primary benefit of this change is the removal of "deprecat.h" from 23
sound cores. I also adjusted ui.c to stop calling sndnum_clock and
access the clock data similarly to how it does the cpu clock data.

02683: Pressing F5 while running debugger causes access violation
02669: pandoras: music tempo is too fast
02691: Some drivers with z80/ay8910 Audio: Audio tempo has changed
Also fixed debugger memory leak.
Added a number of new cputag_* macros to cpuexec.h.
To fix this, I had to break old INP files. While I was in there,
I added corefile support for compressing/decompressing data on
the fly, and enabled it for INPs, meaning the newer format INPs
are output and processed compressed.
Added the concept of 'subviews' to the debugger views. The core
now creates a list of possible subviews, and the OSD can select
between them. This removes code from the OSD that was previously
required to find all possible memory and disassembly views.
Added machine parameters to debugger console output functions.
Fixed some oddities in the memory view.
Moved globals to hang off of the machine structure.
Fixed bug where the visiblecpu was not updated immediately upon
a break.
Important note for OSD ports: the get/set property functions have
been retired for debug_views. Instead, there are specific functions
to perform each get/set operation. In addition, the format of the
update callback has changed to pass the osd private data in, and
the update callback/osd private data must be passed in at view
allocation time. And osd_wait_for_debugger() now gets a CPU object
instead of the machine.
Removed extra debugger tracking for address spaces and added some
of the useful data to the address_space structure. Updated all
debugger commands and views to use CPU and address space objects
where appropriate.
Added new memory functions for converting between bytes and
addresses, and for performing translations for a given address
space. Removed debugger macros that did similar things in favor
of calling these functions.
Rewrote most of the memory view handling. Disasm and register views
still need some additional tweaking.

It should also be noted that many games using this chip are clipping at the moment. This is something that might date back to when sound mixing was upgraded to 32-bit. It is sensible for the 6295 emulator to output at this level because it ensures that bits of precision are not lost, so the mixing levels in the drivers should be adjusted to avoid clipping.

We can't test these, I gave Robbie a final deadline on them a long time ago now.
If you're the one who dumps something and put the rest of the team in a situation where the submission can't be tested, then don't expect the driver to stay. Numerous chances have been given.
Unacceptable due to inability to test.
I won't be writing this driver, it fits somewhere between System21 and System22, with multiple PCBs etc. I just created this to document what we know so far. Chances are Phil or somebody with good Namco knowledge will have to emulate it.
Removed ATTOTIME_TO_CYCLES() and ATTOTIME_IN_CYCLES(). Replaced them
with functions in cpuexec: cpu_clocks_to_attotime() and
cpu_attotime_to_clocks(), both of which take CPU devices instead of
indexes. Updated all callers, many of which were using the functions
dubiously.

Subject: Oki MSM6258 ADPCM core
Hi,
I have attached the Oki MSM6258 ADPCM sound core, which is intended for
use with the MESS Sharp X68000 driver. This code was written by Phil
Bennett, so he ought to be the one getting the credit for it. I have
mostly worked on the MESS X68000 driver and HD63450 (DMA controller)
code to get the ADPCM working for most X68000 software. I am unaware as
to if Phil has already submitted this or not yet.
I've tested compiling and running MAME itself (including a debug build)
with the MSM6258 core in it, and experienced no issues. Although there
is nothing in MAME to test it specifically with, it doesn't cause any
problems with MAME use in general.
The current MESS X68000 driver code with the MSM6258 enabled is
available for those that want to test that out -

works. Added callback parameters to the expression engine. Improved
CPU parsing so you can use a CPU tag or index in most commands that
take one. Switched to passing CPU and address space objects around
where appropriate. Lots of other minor tweaks.
Moved memory global state into a struct hanging off of the machine.
Updated almost all memory APIs to take an address_space * where
appropriate, and updated all callers. Changed memory internals to
use address spaces where appropriate. Changed accessors to point
to the memory_* functions instead of the address space-specific
functions. Improved internal handling of watchpoints.
Added cputag_* functions: cputag_reset(), cputag_get_index(),
cputag_get_address_space(). These just expand via macros to an
initial fetch of the CPU via cputag_get_cpu() followed by the
standard CPU call.
Added debugger_interrupt_hook() and debugger_exception_hook() calls
which intelligently look at the debugger flags before calling.
Did minimal cleanup of debugger, mainly moving CPU-specific data
to hang off of the CPU classdata for more direct access.
return a boolean indicating whether the given address was successfully
located in a bank. Change raw/decrypted access to look at this result, and
if the given address is not in a bank, calls through to the standard read
handlers.
In theory, this should prevent crashes when accessing opcodes. It does in
fact prevent mp_col3 from crashing.
Fixed address space mapping handlers to invalidate direct access regions
if a change is made to the mapping. This is needed to prevent the Sega
dynamic memory mapping chips from falling over.

Cleaned up names of pointers (decrypted and raw versus rom and ram).
Added inline functions to read/write data via any address space.
Added macros for existing functions to point them to the new functions.

into the core proper and removed unused macros. Changed all
external interfaces to pass the CPU device. Enabled 64-bit
operations by default. Re-derived the interface functions to
cascade and share code more aggressively.
These changes also seem to have cured the taito_f3 issues as
far as I can tell (at least pbobble3 seems right now).
state_save_combine_module_and_tag() function in favor of passing
the tag when registering. Revisited all save state item registrations
and changed them to use the tag where appropriate.
This patch implements a "plug-in board" device for the Naomi.
It represents the rom boards for the various games and the dimm board for the gdrom.
Now the dimm board part contains only a routine to load the "rom file" from the gdrom chd, but in the future it will be fully implemented with its own sh4 processor, security chip and so on.
Extracted .rom files are no longer needed, rom file is extracted in code from the CHD.

Changed READ/WRITE handlers to accept an address_space * instead of a

and a pointer to the relevant CPU object.
Fixed a number of errors found by the compiler, mostly in the core and
CPU/sound handlers, but there is a lot remaining to fix.
Added new function cpu_get_address_space() to fetch the address space
for calling in manually to these functions. In some instances, code
which should eventually be converted to a device is hard-coding fetching
the program space of CPU #0 in order to have something valid to pass.

The gun reading is hacked, as are the gun interrupts. This needs fixing *properly*, at which poin I imagine it will actually work, and no just hang after calibration. From what I can tell it's never worked after calibration hence the demotion.

[Oliver Stoeneberg]
With Aaron's change to macroize the cpu apis, the cpu/sound interfaces
are now using different idioms. This patch fixes that. It uses the
prefix SND_ instead of SOUND_, to avoid changing SOUND_START,
SOUND_RESET in driver.h. While working on it, I noticed that the
reset routines for k053260, msm5205, upd7759 and vlm5030 aren't hooked
up, but I decided this was an oversight and macroized the functions
anyways (but left them unhooked).
related APIs now take a device pointer instead of an index.
All functions that take a CPU device are prefixed with cpu_*
All functions that are globally related to cpu execution
are prefixed with cpuexec_*. Below is a list of some of the
mappings:
cpu_boost_interleave -> cpuexec_boost_interleave
cpunum_suspend -> cpu_suspend
cpunum_resume -> cpu_resume
cpunum_is_suspended -> cpu_is_suspended
cpunum_get_clock -> cpu_get_clock
cpunum_set_clock -> cpu_set_clock
cpunum_get_clockscale -> cpu_get_clockscale
cpunum_set_clockscale -> cpu_set_clockscale
cpunum_get_localtime -> cpu_get_local_time
cpunum_gettotalcycles -> cpu_get_total_cycles
activecpu_eat_cycles -> cpu_eat_cycles
activecpu_adjust_icount -> cpu_adjust_icount
cpu_trigger -> cpuexec_trigger
cpu_triggertime -> cpuexec_triggertime
cpunum_set_input_line -> cpu_set_input_line
cpunum_set_irq_callback -> cpu_set_irq_callback
In addition, a number of functions retain the same name but
now require a specific CPU parameter to be passed in:
cpu_yield
cpu_spin
cpu_spinuntil_time
cpu_spinuntil_int
cpu_spinuntil_trigger
cpu_triggerint
Merged cpuint.c into cpuexec.c. One side-effect of this
change is that driver reset callbacks are called AFTER the
CPUs and devices are reset. This means that if you make
changes to the CPU state and expect the reset vectors to
recognize the changes in your reset routine, you will need
to manually reset the CPU after making the change (since it
has already been reset).
Added a number of inline helper functions to cpuintrf.h for
managing addresses
Removed cpu_gettotalcpu(). This information is rarely needed
outside of the core and can be obtained by looking at the
machine->cpu[] array.
Changed CPU interrupt acknowledge callbacks to pass a CPU
device instead of machine/cpunum pair.
Changed VBLANK and periodic timer callbacks to pass a CPU
device instead of machine/cpunum pair.
Renamed all information getters from cpu_* to cpu_get_* and
from cputype_* to cputype_get_*.
Added Simulation of Toybox external data rom decryption from Andreas
Converted Blood Warrior, Bonk's Adventure, Great 1000 Miles Rally 1+2 to use the new code.
Updated suprnova rendering to allow 2 sprite chips.
Started work on Jackie Chan & Gals Panic 3
* sndindex now considered as well in state save
* expose discrete_sound_n_r(void *chip, ...) to enable accessing multiple discrete sound cores
Curt Coder, is this sufficient?
* changed the 6845 type to R6545_1 (Rockwell as mentioned in the driver).
* use transparent addressing
* lightpen code now generates a "lightpen_assert" at the right screen position.
* Completely hooked up 6545 without wrappers.
* implemented support for phi1/phi2 transparent addressing
* added callback to communicate address back to driver
Implementation is not and can not be "clock" accurate since the timing is totally up to the hardware implementation. It is the main cpu and hardware which determines phi clocking and when data is written to video ram. The only support in the 6545 is that the update address is latched out to the ma lines during phi2.
(program roms are identical to Vs. Super Mario Bros. (alt),just the graphical roms are completely reworked,I don't know if it is worth supporting...)
(PS: do not credit me on this)
context ones (which are going away), the disassembler (which should
have no dependencies on the live CPU), and the validity check.
Removed global token from all pointer-ified CPU cores that don't
have internal read/write callbacks (which still need to reference it).
* added a set of cpu_* calls which accept a CPU device object;
these are now the preferred means of manipulating a CPU
* removed the cpunum_* calls; added an array of cpu[] to the
running_machine object; converted all existing cpunum_* calls
to cpu_* calls, pulling the CPU device object from the new
array in the running_machine
* removed the activecpu_* calls; added an activecpu member to
the running_machine object; converted all existing activecpu_*
calls to cpu_* calls, pulling the active CPU device object
from the running_machine
* changed cpuintrf_push_context() to cpu_push_context(), taking
a CPU object pointer; changed cpuintrf_pop_context() to
cpu_pop_context(); eventually these will go away
* many other similar changes moving toward a model where all CPU
references are done by the CPU object and not by index
* cpu/i8x41 should be renamed to UPI-4x, since UPI-41/42 was an intel chip family
postponed for now until core moved to pointers.
* removed I8041 definition from mcs48
* removed I8x41 cpu definition and config struct
* added I8041, I8741, I8042, I8242 and I8742 cpus to i8x41.c
* added internal memory maps
* internal ram now uses DATA memory space
* updated drivers
* increased interleave to 70 in decocass. This fixes decocass hanging in countdown around 13

Subject: [patch] Add ADDRESS_MAP_NAME macro
Hi mamedev,
In theory, MAME's interface macros should completely hide the naming
conventions from the drivers and sound/cpu cores. So as an
experiment, I renamed all the core apis and looked to see what broke.
The most common api coupling was with address maps in the CPU cores,
which this patch addresses by introducing a new macro,
ADDRESS_MAP_NAME (mimicing what is done in devintrf.h). There were a
handful of related problems in some drivers which this patch also
fixes. Some remaining issues I left alone (laserdisk apis reference
rom, video_update, machine_config, ksys573 use of nvram_handler,
megadriv use of ipt), in principle all the apis need _NAME variants to
encode the conventions.

remaining ones later. Alternately, you can drop the patches for now
and I'll resubmit them later.

Subject: [patch] State save support for toaplan2
Hi mamedev,
Attached is a small patch to add a toaplan2.h include file and save
state support for the driver. A number of variables changed from int
to specific sizes to support this, and I also fixed a harmless typo in
the mem_mask size.

Hi folk!
Another work in expro02 drive:
- Fixed dips in all galsnew sets and fantasia.
- Added dips location.
- A little drive clean up.

adds/removes entries in header files, and fixes a few potential
multisession issues by explicitly adding initializers. asic65.c has
significant changes to accomodate using a struct instead of 16
variables, otherwise the changes in this patch are modest and obvious.

There's an issue with the debugger handling of the 6502 instructions as
there's a mismatch between the core and what the debugger shows.
The changes are detailed in the spreadsheets that I've attached that
compares the core to the dasm.
Attachments:
m6502fix.zip contains the diff file
6502 debugger disassembly changes.zip contains an excel spreadsheet
(in both xls and xml formats) detailing the reasons/changes.
* bbusters.diff:
- Fixed service mode issues enabling extra RAM that was previously unmapped.
- Properly implemented all sound communications.
- Fixed ID 00387. (there are no sound issues, the bug in my opinion is no more valid)
* nmk16.diff
- Fixed ID 00224. (PCB behaviour verified by Corrado Tomaselli)
* renegade.diff
- Fixed ID 01679. (old code was an hack, cpu_getiloops is more acceptable)
* suprnova.diff
- Fixed ID 02042. (no other games are broken)
* twin16.diff
- Cleaned up a bit code to make it more readable.
- Reorganized CPUs order in all games. (main, sub, audio)
- Fixed ID 02268. (guesswork, a PCB is needed to understand how priorities work)
and removed an unnecessary hack from the driver.Probably one of Arbee's SCSP changes fixed it.

Buena Suerte '94 [Grull Osgo, Roberto Fresca]
Hello, with this patch finally cvs2gd stops looping forever. However with
no 3d emulation nothing is shown on the screen.
Then i have implemented the naomi RTC and there are a few verbose messages
about transfers not implemented yet.
* improved prefetch timing calculation
* prefetch timing now also used by V20 and V33
* moved some static variables into cpu context
* nec_reset now explicitly clears context variables
* all cpus now share nec_execute
Would whoever checked this in double-check my change? I believe I got the intent of the code (which is not how it was written ;-) but I could be wrong.
--This line, and those belo
M disc_flt.c
* The whole startup cycle now works. No more timeouts and erratic behavior.
* lohtb2 will however not display the "Warning" screen due to a priority issue. With color/attribute of 0x80 in videoram at 0xd0000 and 0xd8000, videoram at 0xd80000 will be displayed. Some tilemap guru has to look into this.
Credit Jim (or however he wants his name listed ;-)
Also specifies the difference between the two Ghox sets (in toaplan2.c). One set is 8-way joystick controls and the parent is a spinner with forward/backward single axis control
* Fixed tilemaps paging / tilemap positioning;
* Fixed a protection issue in Mahjong Daireikai,not giving correct colors for the girls in-game;
* Fixed a rom-loading issue in Mahjong Daireikai;
* Fixed 'ZA' sound banking behaviour,this fixes at least the sound in kakumei2;
* Removed VIDEO_EOF and added a TIMER_DEVICE_CALLBACK function for MCU simulations;
* Added WIP code for the priority system;
* Added a NO_DUMP for the MCU for all the sets;
- emulates Braze Technologies addon board
- eeprom hooked up
- implemented bank switching
I am still unsure about whether this should be added or not.
Interestingly, D2K shows a "(C) 1981 Nintendo" copyright message.
Still, it is actively marketed.
Putting this up for discussion again.
- Added sound support to magicfly and 7mezzo.
- Hooked coin counters to magicfly and 7mezzo.
- Inverted the graphics banks to be straight with the hardware accesses.
- Updated the memory map description and technical notes.
- Added game notes and documented the test/settings/bookkeeping modes.
Ruleta RE-900 from Entretenimientos GEMINI.
Is a roulette game based on i8051 and TMS9928, that has a phisical roulette with leds simulating the ball.
Game is working properly with full sound support.
Need better inputs implementation, leds, external artwork for the roulette and technical notes (I'm taking care of them).
If someone want to give a try, turn the operator key to allow enter credits.

Subject: Sound Support for Cosmic Alien
Hello,
I own a cosmic alien PCB and so I thought it would be a good idea to add
sound support
to this game by changing the corresponding driver ("drivers\cosmic.c").
I also have recorded the different sound effects as wave - files.
I have attached two files to this mail. The file "cosmica.zip" contains
the samples
(so it can be simply copied to the "samples" folder) and
the other one "cosmica_diff.zip" contain the "diff" file taken against
the 0128 sources.
So you can check it and maybe you want to implement the changes in a
further release?
best regards

Subject: fix for mt 2577
the wrong tags were used for maketrax when indexed inputs were converted to tagged ones (0.125u7): input 2 was 'dsw1' but 'in1' was used. probably a mistake I made. sorry.

Subject: 65c02 core bugfix
Hi,
This patch fixes a subtle bug in the 65c02 emulation where the result of
the BIT instruction differs on the 65c02 (from the 6502), when executed
in immediate mode.
Cheers,
Phill.

Double Dealer [Angelo Salese,David Haywood]
* Remaining games checked and adapted to changes in cpu core
* Cardline still broken. I need the exact and complete cpu name.
* Added more variants 803X, 80CXX, AT89C4051
* Fix segas18.c (segaic16.c) mcu maps.
* Fix sslam.c
* Fix limenko.c videopkr.c : Issue with core allocation of ram (duplicate savestate)
Yet another 8-bit Incredible Technologies board. Different in several
significant ways from previous models:
* YM2608B for audio, replacing YM3812+OKI6295
* TMS34070 for palettes instead of PC RAMDAC
* Different video memory layout
* improved serial port timing (f15se (micro3d.c) sound board now works)
* better infrastructure for adding more variants like DS5002
* Fixed port reading
* Rewrote Macros for better readibility
* Fixed and rewrote Interrupt handling
* Now returns INTERNAL_DIVIDER, adjusted cycle counts
* Remove unnecessary and duplicated code
* Remove unnecessary functions
* Rewrite to have sfr-registers stored in int_ram.
* Debugger may now watch sfr-registers as well.
* implemented interrupt callbacks (HOLD_LINE now supported)
* Runtime switch for processor type - remove ifdefs
* internal memory maps for internal rom versions (internal ram now displayed in debugger)
* more timer cleanups from manual
micro3d:
* serial port communication between main cpu and sound board works
* sound board now works
m72 - lohtb2:
* full emulation of protection device
* Samples are now piped through the mcu
* Added additional branch, move and bitfield ops.
* Plygonet now passes its memory test and uploads a new program.
[[Next step is to install an opbase handler and let the dsp56k run further into its new proggie.]]

(Medal) Yumefuda [Bet] [Angelo Salese]
* Complete rewrite focusing on legibility and extensibility.
* 27/121 opcodes (mostly) implemented.
* Bugfix for reset status of interrupt priority bits.
* Bugfix for disassembly of register-to-register parallel data move.
[[These changes bring the driver up to the point where the plygonet hardware begins banking memory. The behavior is understood, so I should have the driver back to where it was before the rewrite soon. Then real progress can be made.]]
(also added a to-check note, 16-bit wide DMA is currently using 32-bit functions, is this correct?)
Removed Speedups from CPS3 / PsikyoSH, while they do still give a decent speed boost they're not really needed with the DRC and just clutter the code.
