- All games on all drivers should work as before except "colmns97" and "stress" which crash due to sound system trouble.
- All idle skips are still included. They are quite a bit less effective than they were on the interpreter, but they still give a boost.
- Fast RAM bypass is not included yet so this does not represent final performance. That said, it's consistently faster than the interpreter even now. Example: sfiii3 on 0.126 gets 609% on the interpreter and 961% on the DRC.
Major thanks to Aaron for his assistance with several sticky core bugs and other issues encountered writing this.

Added new module uiinput.c which manages input for the user interface.
The OSD is responsible for pushing mouse events and character events
to this interface in order to support mouse movement and text-based
input (currently only used for the select game menu). Added support
for navigating through the menus using the mouse.
[Nathan Woods, Aaron Giles]
Redesigned the UI menus so that they can maintain a richer state. Now
the menus can be generated once and reused, rather than requiring them
to be regenerated on each frame. All menus also share a comment eventing
system and navigation through them is managed centrally. Rewrote all the
menus to use the new system, apart from the cheat menus, which are now
disabled. Reorganized the video menu to make it easier to understand.
[Aaron Giles]
- Set the proper screen size.
- Decoded graphics.

macro from the source code. All MAME builds now include
the debugger, and it is enabled/disabled exclusively by
the runtime command-line/ini settings. This is a minor
speed hit for now, but will be further optimized going
forward.
Changed the 'd' suffix in the makefile to apply to DEBUG
builds (versus DEBUGGER builds as it did before).
Changed machine->debug_mode to machine->debug_flags.
These flags now indicate several things, such as whether
debugging is enabled, whether CPU cores should call the
debugger on each instruction, and whether there are live
watchpoints on each address space.
Redesigned a significant portion of debugcpu.c around
the concept of maintaining these flags globally and a
similar, more complete set of flags internally for each
CPU. All previous functionality should work as designed
but should be more robust and faster to work with.
Added new debugger hooks for starting/stopping CPU
execution. This allows the debugger to decide whether
or not a given CPU needs to call the debugger on each
instruction during the coming timeslice.
Added new debugger hook for reporting exceptions.
Proper exception breakpoints are not yet implemented.
Added new module debugger.c which is where global
debugger functions live.
Subject: [patch] Static qualifiers, header file cleanups, and new
include files for MAME
Hi mamedev,
The following two patches improve the use of header files in MAME, and
reduce the number of exported symbols.
The second patch then adds ~30 header files for a number of drivers
that use multiple source files. It consolidated the various cchip
related declarations in cchip.h, and added machine/seicop.h as well.
~aa
Added dumper notes, hardware details and hooked the sound devices.
Moved Euro Jolly X5 to this new driver, and add support for Grand Prix.

* Wrote new disassembler based on enhanced opcode info structure.
* Moved disassembler into drcuml.c and removed old code.
* Extended disassembler buffer sizes to at least 256 bytes.
- rewrote PowerPC implementation as a dynamic recompiler on top
of the universal recompiler engine
- wrote a front-end to analyze PowerPC code paths and register usage
- wrote a common shared module with C implementations of tricky
CPU behaviors
- added separate CPU types for the variants supported, instead of
relying on a hidden model enum
- rewrote the serial port emulation for the 4xx series to be more
accurate and not rely on separate DMA handlers
- rewrote the MMU handling to implement a software TLB that faults
in pages and handles changed bits appropriately
- implemented emulation of the PowerPC 603's software TLB, which
allows the model 3 games to run without a hack to disable the MMU
Updated the PowerPC disassembler to share constants with the rest of
the core, and to more aggressively use simplified mnemonics, especially
for branches. [Aaron Giles]
Universal recompiler:
- fixed frontend to handle opcode widths different from bus width
- added several new opcodes:
* (D)GETFLGS - copies the UML flags to a destination operand
* FDRNDS - rounds a double precision value to single precision
- renamed several opcodes:
* SETC -> CARRY
* XTRACT -> ROLAND
* INSERT -> ROLINS
- consolidated the following opcodes:
* LOAD?U -> LOAD
* LOAD?S -> LOADS
* STORE? -> STORE
* READ?U -> READ
* READ?M -> READM
* WRITE? -> WRITE
* WRITM? -> WRITEM
* SEXT? -> SEXT
* FTOI?? -> FTOINT
* FFRI? -> FFRINT
* FFRF? -> FFRFLT
- removed some opcodes:
* FLAGS - can be done with GETFLGS/LOAD4/ROLINS
* ZEXT - can be achieved with AND
* READ?S - can be achieved with READ/SEXT
- updated C, x86, and x64 back-ends to support these opcode changes
- updated disassembler to support these opcode changes
MIPS3 dynamic recompiler:
- updated to use new/changed opcode forms
- changed context switch so that it only swaps a single pointer
Konami Hornet changes: [Aaron Giles]

Subject: saturn CPU patch
Dear MAMEDev,
The attached patch corrects several bugs in the emulation of the saturn
CPU. These corrections are needed to make new HP48 drivers (to be
submitted to MESS imminently) work.
AFAIK, MESS is the only place where this CPU is used, so, the patch
should
not cause any regression in MAME.
The patch is against 0125u1.
Best regards,
-
Antoine Mine
* Input ports are now maintained hierarchically. At the top
level are input ports, which contain a list of fields. Each
field represents one or more bits of the port. Certain fields
such as DIP switches and configuration switches contain a
list of settings, which can be selected. DIP switch fields
can also contain a list of DIP switch locations.
* Normalized behavior of port overrides (via PORT_INCLUDE or
by defining multiple overlapping bits). All fields within a
port are kept in strict increasing bit order, so altered DIP
switches are now kept in the appropriate order. This addresses
MAMETesters bug 01671.
* Live port state is now fully separate from configured
state. This is manifested in a similar way to devices, where
a const list of ports can be managed either offline or live.
Each port has a pointer to an opaque set of live state which
is NULL when offline or valid when live. Each port also has
a running_machine * which is also NULL when offline.
* Because of this new arrangement, the conversion from tokens
to a list of ports now requires reasonably complex memory
allocation, so these port lists must be explicitly allocated
and freed (they are not mantained by automatic resource
allocation).
* Custom and changed callbacks now take a pointer to a field
config instead of a running machine. This provides more
information about what field triggered the change notification.
The machine can be found by referenced field->port->machine.
* The inptport.c module has been cleaned up and many
ambiguities resolved. Most of this is internal, though it did
result in osd_customize_inputport_list() being changed to
osd_customize_input_type_list(). The parameter to this function
is now a linked list instead of an array, and the structures
referenced have been reorganized somewhat.
* Updated config.c to pass machine parameters to its callbacks.
* Updated validity checks, XML output, and UI system to handle
the new structures.
* Moved large table of default input settings to a separate
include file inpttype.h.
* Removed gross hacks in trackfld and hyperspt NVRAM. These
may be broken as a result.
is drcuml.c, which defines a universal machine language
syntax that can be generated by a frontend recompiler and
then retargeted via a generic backend interface to any of
a number of different architectures. A disassembler for the
UML is also included to allow examination of the generated
UML code.
Currently supported backend architectures include 32-bit x86,
64-bit x86, and a platform-neutral interpreted C backend that
can be used as a fallback for platforms without native
support. The C backend also performs additional validation
to ensure assumptions are met.
Along with the new architecture is a new MIPS III/IV
recompiler frontend. This frontend has been rewritten from
the old x64-specific recompiler to generate UML opcodes
instead. This means that the single recompiler can be used
to target multiple backend architectures and should in
theory produce identical results across all of them.
The old 32-bit and 64-bit MIPS recompilers are now officially
retired. The new system provides similar performance (within
5% generally) to the old system and has similar compatibility.
The only currently known issues are some problems with the
two Gauntlet 3D games.
- Properly decoded graphics.
- Proper memory map.
- Added NVRAM support.
- Proper Inputs through 8255 PPI I/O chip.
- Both games are working.
- Added technical & game notes.

* adds a model to calculate mixing of channels with different resistance loads.
* based on above, each channel may be assigned a different load in individual case
i.e. channels not tied together
* rewrote ay8910.c to make emulation simpler
* changed the config structure to include a flag field and output resistor loads.
* Updated all drivers affected.
* Added some "Todos" related to stuff I discovered when reading datasheets.
* Fixed a bug in disc_flt.c (konami filters)
galaxian.c:
* Fixed discrete sound and konami filter addressing
* Changed addressing of AY-3-8910 to be in line with schematics
gyruss.c:
* Added discrete sound for filtering ("konami"-style) and mixing.

Subject: pit8253 device
I have converted the pit8253 implementation into a device. To make it
easier to use I've also created a src/emu/devconv.h in the same style
as src/emu/memconv.h.

been able to test pf2012, filetto, and topgunnr.
Subject: Internal LAY File - Armor Attack
This is becoming kind of fun. Here's an internal LAY file for Armor Attack.
Re-created the overlay using just rectangles.
And finally got to use flipx and flipy for the first time (main reason I did it).
* Give us a Break [2 sets]
* Ten Up [2 sets]
Neither are playable; they don't register coins for some reason.
2. Fixed interrupt handling and 16-bit memory accessors in 6840ptm.c
Also cleaned up code for the sake of readability.
3. JPM games now have their own object archive file.
for galaxian, scramble, frogger, scobra, amidar, and dambustr.
For the moment, only a subset of games are implemented in the
new system; the remainder are running on the old code.
Main features are accurate video timing, correct stars
implementation, better organization, simplified input ports,
and many other smaller fixes. In addition, the following
MAMETesters bugs are addressed:
- 01598: [Graphics] 4in1, gmgalax, pacmanbl: Sprites are cut off on the top row
- 01563: [DIP/Input] gmgalax: Duplicated Inputs
- 00300: [Graphics] zigzag: in cocktail mode player 2 screen is shift over to the right
