Please note: regression testing is in progress, but the first round
of glaring regressions have already been taken care of. That said,
there is likely to be a host of regressions as a result of this
change.
Also note: There are still a few rough edges in the interfaces. I
will try to clean them up systematically once the basic system is
working.
All sound chips are now proper devices.
Merged the sound chip interface into the device interface,
removing any differences (such as the whole ALIASing concept).
Modified every sound chip in the following ways:
* updated to match the device interface
* reduced read/write handlers down to the minimal number
* added the use of get_safe_token() for ensuring correctness
* other minor cleanup
Removed the custom sound device. The additional work to just make
custom sound cases into full devices is minimal, so I just converted
them all over to be actual devices.
Vastly simplified the sound interfaces, removing the ghastly
sndti_* business and moving everyone over to using tags for
sound identity. sndintrf, like cpuintrf, is now just a header
file with no implementation.
Modified each and every driver that references a sound chip:
* all memory maps explicitly reference the targeted device via
AM_DEVREAD/AM_DEVWRITE/AM_DEVREADWRITE
* 16-bit and 32-bit accesses to 8-bit chips no longer use
trampoline functions but instead use the 8-bit AM_DEVREAD/WRITE
macros
* all references to sound chips are now done via tags
* note that these changes are brute force, not optimal; in many
cases drivers should grab pointers to devices in MACHINE_START
and stash them away

TomCat (prototype) [Mariusz Wojcieszek]
There are still some small issues (complete list in driver), if somebody with more experience with Atari and/or vector hardware wants to take a look, feel free.
Merging back in the PinMAME drivers is proposed every now and again, and since we've just added other non-video based things I figured that now might be a good time to look at it.
This is likely to be a HUGE undertaking as PinMAME is based on old code, and is Macro-hell, I see it as a several step plan.
1) Convert all the PinMAME drivers to compile their ROM Loading with current versions of MAME
2) Clean up the ROM loading, removing the excessive Macros which really don't help readability at all IMO
3) Hook up the Machine Drivers again for each system, so that the CPU core runs again
4) Look at ways in which the artwork system can be used to simulate the display parts etc. (there is a scary amount of code in PinMAME for handling this stuff)
5) See how feasible it is to allow MAME to communicate with another program, as it's unlikely we'll be able to simulate the full table physics in MAME.
I've updated the System11 rom loading to compile for now. The old PinMAME code which hasn't been updated is there #if 0'd out for reference for when a stab is made at hooking back up the actual CPUs to run etc.
Part of me wonders if just rewriting it from scratch would be easier, but it would be a shame to throw away the information that was figured out in PinMAME.
This was done by request, so I'm not especially bothered if it doesn't get included, PinMAME is rather hideous ;-)
If anybody wants to help they're more than welcome. The other Williams systems should be easy to hook up the rom loading for because they share most of the Macros that have already been updated to compile.

6850acia: Only adjust the rx/tx bit timers on a control write if the divide ratios have changed.
- Merged GTI Poker (gtipoker.c) with this driver.
- Added new memory map and machine driver for gtipoker.
- Hooked 2x PPI 8255 to gtipoker.
- Hooked the video RAM access ports to gtipoker.
- Changed norautpn description from Noraut Poker (No Payout),
to Noraut Poker (bootleg), since the game has payout system.
- Some clean-ups.
read/write functions and various other types of functions. Introduced new
structures and macros to make this possible.
To take advantage of this, a device must change its interface to replace and
read/write callbacks with the new devcb_read/write structures. During device
start time, the device then uses this new devcb module to resolve the information
in the devcb_read/write structures into a more efficient form. When the device
needs to call one of the callbacks, it uses the inline devcb_call_read/write
functions.
Once a device has defined its callbacks as devcb_read/write structures, users
of the device must use the DEVCB_* macros to specify the type and information
about the handler to use:
DEVCB_NULL = no handler
DEVCB_HANDLER = a standard device read/write handler
DEVCB_MEMORY_HANDLER = a memory address space read/write handler
DEVCB_DEVICE_HANDLER = a device read/write handler for a different device
DEVCB_INPUT_PORT = an input port
Converted the 8255PPI device to use this new structure, and updated all users
to use the DEVCB macros, removing some unnecessary trampoline functions along
the way.

Intel i860 CPU core added. [Jason Eckhardt]
(The CPU core doesn't have accurate cycle counts for each opcode yet, but it'll have them soon. I believe that is the main culprit behind the sync of the two i860s and the 68k being outta' whack. You can still see the i860s do their thing and rasterize a voxel? groundplane and some simple polygon bad guys).
- Added built-in dirty tile tracking to the gfx_element. This removes
the need for all drivers that had dynamically populated graphics
to do their own dirty tracking. Tiles are marked dirty via the
new function gfx_element_mark_dirty(). Any driver that needs access
to the decoded data must call gfx_element_get_data() in order to
ensure that the referenced tile is clean before proceeding.
- In order to support dirty tracking, the gfx_element was enhanced to
keep track of the original source pointer, so that it can go back
and regenerate tiles on demand. For systems that set NULL for the
region in the gfxdecode, they must use gfx_element_set_source()
to specify a pointer to the raw data before drawing anything.
- Changed allocgfx() to gfx_element_alloc(), and added parameters to
specify the source data pointer, base color index, and total colors.
Many drivers had to whack these values in after the fact, so this
allowed for some minor additional cleanup.
- Added a dirtyseq member to the gfx_element struct. This is
incremented on each tile dirty, and can be used to sniff if
something has changed.
- Added logic in the tilemap engine to track which gfx_elements are
used for a given tilemap, and automatically detect changes to the
tiles so that drivers no longer have to explicitly invalidate the
tilemap when tiles change. In the future, this may grow smarter to
only invalidate the affected tiles, but for now it invalidates the
entire tilemap.
- Updated a number of drivers to remove their own dirty handling and
leverage the new internal dirty marking.
- Because the source data must always be present, updated the atarigen
zwackery and mystwarr graphics handing code to support this.
- Thanks to the dirty tracking, this actually allows all gfx decoding
to happen on the fly instead of all at once up front. Since there
was some concern that this would cause undesirable behavior due to
decoding lots of tiles on the fly, it is controlled with a compile-
time constant in mame.h (PREDECODE_GFX). Set this to 1 to get the
old behavior back.
- Moved decodechar() and decodegfx() to deprecat.h. All drivers in MAME
have been updated to simply mark tiles dirty and let the rendering
system decode them as needed, so these functions may go away in the
future.
- Rewrote entirely the rendering code in drawgfx. This code previously
used extensive recursive #includes and tricks to build, and was
very difficult to understand. The new code is based off of a set of
macros defined in drawgfxm.h. These new macros separate the core
rendering logic from the per-pixel operation, allowing the operation
to be easily "plugged" into any of the renderers. These macros are
also available to any driver that wants custom rendering behavior
that is similar to existing core behavior, without needing to
populate the core with esoteric one-off rendering behaviors.
- Added a set of new functions for [p]drawgfx[zoom], one for each
transparency type. The old [p]drawgfx[zoom] functions are still
present, but now switch off the transparency type and call through
to one of these new transparency-specific functions. The old
functions are also now reduced to only supporting TRANSPARENCY_NONE,
TRANSPARENCY_PEN, and TRANSPARENCY_PENS. All other rendering types
must use the new functions.
- All new rendering functions have extensive asserts to catch improper
clipping rectangles and other common errors.
- All new rendering functions automatically downgrade to optimized
versions where appropriate. For example, calling drawgfx_transpen
with an out-of-range pen automatically falls back to drawgfx_opaque.
And drawgfxzoom_* with xscale=yscale=1.0 automatically falls back
to drawgfx_*. And many other examples. In general, this relieves
drivers from needing to make these sorts of decisions.
- All new rendering functions have a consistent parameter order that
is a bit different from the existing functions. The cliprect
parameter is now specified immediately after the destination bitmap,
to match the convention used throughout the rest of the system.
The core parameters are followed by the scale parameters (for the
zoom functions), and then followed by the priority parameters (for
the pdrawgfx* functions), finally followed by any PIXEL_OP*-specific
parameters (such as transparent pen, alpha, drawing tables, etc.)
- Removed drawgfx_alpha_cache, alpha_set_level(), and the inline
functions alpha_blend16() and alpha_blend32(). To render graphics
with alpha, use the new [p]drawgfx[zoom]_alpha functions, which
take an explicit alpha value. To render tilemaps with alpha, the
TILEMAP_DRAW_ALPHA option now takes an explicit alpha parameter.
And to do you own alpha blending, use the alpha_blend_r16() and
alpha_blend_r32() functions, which take an explicit alpha.
- Updated a number of drivers as a result of removing the implicit
alpha in the drawgfx_alpha_cache.
- Removed drawgfx_pen_table and TRANSPARENCY_PEN_TABLE. To achieve
the same effect, build your own table and pass it to
[p]drawgfx[zoom]_transtable, along with a pointer to the
machine->shadow_table to use for shadows. Eventually
machine->shadow_table is likely to go away, and drivers will need
to fetch the shadow table from the palette directly.
- Updated a number of drivers to remove use of drawgfx_pen_table.
- Removed TRANSPARENCY_ALPHARANGE; it was only used by the psikyosh
driver, so it is now moved locally into that driver and built
using the macros in drawgfxm.h.
- Removed TRANSPARENCY_PEN_RAW; to achieve the same effect, call the
new [p]drawgfx[zoom]_transpen_raw() functions. Updated drivers to
make this change.
- Removed the unused mdrawgfx* functions entirely.
- Added new function gfx_element_set_source_clip() to specify a
source clipping rectangle for any element. This replaces the nasty
hacks that were being used in bnstars, ms32, namcos86, and namcos1
to achieve similar behaviors.
- Simplified the copyrozbitmap() functions to match the copybitmap()
functions in having separate opaque and transparent versions. Also
removed the 'priority' parameter which was only used by one driver,
and moved that logic into a custom renderer built using macros in
drawgfxm.h. Updated copyrozbitmap* to use the destbitmap, cliprect
parameter ordering convention as well.
- Simplified the draw_scanline*() functions to always render opaque.
Only one driver was doing otherwise, and it now does its work
internally (draw_scanline is dead-simple ever since we moved
rotation to the OSD code; I almost just removed it entirely).
Other changes:
- Added a cliprect to the bitmap_t type, which describes the full
bitmap.
- Removed tilemap_set_pen_data_offset; unfortunately, this adds a
random tile offset behind the scenes and goes against the dirty
tile detection and invalidation. Updated the mainsnk, snk, and
snk68 drivers to use old fashioned tile banking. (Sorry Nicola.)
- Changed zac2650 gfxdecode to use scale factors.
- Added function video_assert_out_of_range_pixels() to help find
the source of invalid pixels (generally out-of-range palette
entries due to invalid data or sloppy calculations). Place this
after each step in your rendering in a debug build to discover
which code is generating improper pixels.
* At the moment only the ADPCM part is implemented, while it's missing the BEEP
generator and the 2nd channel handling, used mainly for echoing or continuous
speech.
