machine/device handlers. Unfortunately, the implementation relies on
sentinel values to distinguish a port tag versus a pointer to function
code. However, since this is a very common situation, it will hopefully
be worth the slight grossness. New macros are defined in inptport.h:
DEVICE8_PORT(name) - use this to specify the name of a port to read
wherever a read8_device_func would normally be used
MACHINE8_PORT(name) - same as DEVICE8_PORT except it can be used
wherever a read8_machine_func would normally be used
IS_HANDLER_PORT(ptr) - accepts a read8_device_func or read8_machine_func
and determines if it is an actual function or a reference to a port;
intended for use by devices that accept DEVICE8_PORT-style functions
CALL_DEVICE8_READ(ptr,device,offset) - either calls through the given
read8_device_func, or calls input_port_read with the appropriate
tag, depending on the result of IS_HANDLER_PORT; intended for use
by devices that accept DEVICE8_PORT-style functions
CALL_MACHINE8_READ(ptr,machine,offset) - same as CALL_DEVICE8_READ
except for read8_machine_func
Note that in order for these to be useful, the consumer of the function
pointer must be enhanced to use the CALL_* macros above instead of directly
calling through the function. So far, only the 8255 PPI is set up to do
this, as part of the cleanup below. Also note that the sentinel value is
currently 4 consecutive 0 bytes; this may need to change in the future, in
either length or value, so it is important to stick to the macros above.
8255 PPI interface cleanup:
- added MDRV_PPI8255_ADD, MDRV_PPI8255_RECONFIG and
MDRV_PPI8255_REMOVE macros; updated all drivers to use them
- changed callbacks to device read/write handlers intead of
machine read/write handlers; updated all drivers accordingly
- normalized function and variable names to be lower_under
- removed a number of redundant interfaces from the galaxian/
scamble line of games
LD-V1000: added some (compile-time removed) information about the
ROM and memory map
* Hooked up 6845
* Hooked up lscnblk line
* Fixed Phraze Craze gfx rom ordering
* Clocks from schematics
* Ram palette moved to static var. This should not be in RAM.
* Added save state support
New Clones
----------
Capcom Sports Club (EURO 971017) [Corrado Tomaselli]
This is newer than any of the other sets, it probably fixes the euro specific crash in the special extended bonus round (at a guess)
expro02.c
- fixed DIPSW
- added graphics decode routine (probably it can be simpler)
video/kaneko16.c
- tilemap scroll position is different for expro02, so added new
function (is it better to fix current one?)
TODO
- in gfx data banking function (newly added), some strange gfx are shown.
Timing issue?
New games added or promoted from NOT_WORKING status
---------------------------------------------------
Gals Panic (US, EXPRO-02 PCB)
Added new item to the interface which is the tag of a CPU
to take the base clock from. Are there any known cases
where the base clock does NOT come from the CPU directly?
Changed Z80 daisy chain interface to simply be a list of
devices in the chain. Interrupt callback functions are now
fetched via the standard device interface and referenced by
the daisy chain code.
Changed Z80 PIO interrupt callback to pass a device instead
of the machine. All device callbacks should provide the
device.
decoded VBI data. Added plumbing for allowing for overall brightness/
contrast/gamma corrections on laserdisc video. Fixed bug when combining
brightness values in the palette logic.
deprecat.h.
Changed render_texture_set_bitmap() to accept a palette object
instead of a palette index. The renderer remains optimized for the
system palette but will work if objects have their own palette as
well.
Changed renderer to permit palettes for RGB and YUY textures. If
specified, these palettes specify a 32-entry (RGB15) or 256-entry
(others) lookup for applying additional brightness/contrast/gamma
on a per-texture basis.
Removed rescale notification. It never really worked that well and
violated proper layering.
Renamed palette_set_brightness() to palette_set_pen_contrast() for
clarity.
Changed palette objects to support global brightness/contrast/gamma
in addition to per-group and per-entry controls.
- uses back-end decoding for CHDs directly to bitmaps
- changed min/max detection to only check 0/255
- fixed off-by-one bug in min/max computation
- separated white code detection from frame number detection
- track cadence with frame numbers as well as white codes
- use vbiparse.h constants where appropriate
- UI_ON_SCREEN_DISPLAY (there is now a "Slider Controls" menu)
- UI_ADD_CHEAT, UI_DELETE_CHEAT, UI_SAVE_CHEAT, UI_WATCH_VALUE, UI_EDIT_CHEAT, UI_RELOAD_CHEAT (these keys belonged to the old cheat engine)
A clean build is required and cfg/default.cfg has to be deleted !
- fix Mantis bug ID 02323 (this might not be the best way though).
- reworked 'geebee', 'navarone' and 'warpwarp' INPUT_PORTS definitions by using conditional Dip Switches.
- added 'geebeeb' INPUT_PORTS definition (this game has specific "Replay" settings).
palette.c to preserve the alpha when transforming palette values.
These changes should be transparent to almost all drivers and rendering
(ha-ha), but there may be an occasional instance where a driver relied
on the alpha being 0 in the system palette. This also means that the
palette_set_color() function preserves any alpha value that is set.
Changed Firefox to RGB32 to allow for mid-screen palette changes. Because
of the above change, the hacky alpha manipulation that was previously
required is no longer necessary; the alpha is set directly in the palette
entry.

compared to other emulator (i.e. kawak), mame does not perform very well in
terms of speed of emulation against Neo Geo games.
Looking at profiling data for these neo geo games, we can see :

3.77 49.95 3.85 35732143 0.00 0.00 memory_region
---------------------------------------------------------
I was wondering why functions like 'astring_cmpc' and 'memory_region' where
in the top 5 of the most time consuming functions.
The answer is found in the function 'draw_sprites' from
'mame/video/neogeo.c' where 'memory_region' is called for each sprites for
each VIDEO_UPDATE.
I patched mame in order to keep track of this 'memory_region'. This is done
in VIDEO_START via a global variable (region_zoomy) just like in some other
drivers.

Subject: Speed up fillbitmap
Hi,
there are many places in mame which make use of "fill_bitmap" or the
equivalent "fillbitmap"
An optimisation is done when the depth of the bitmap is 16 or 32 bpp and
when the UINT16 or UINT32 corresponding to the color is composed of same
bytes (i.e 0xffff for example). This is usefull because most of the calls
are for color 0 (black).
In all other cases, the bitmap is filled one pixel at a time using a loop
with a code like :
================
for (y = fill.min_y; y <= fill.max_y; y++)
{
UINT16 *destrow = BITMAP_ADDR16(dest, y, 0);
for (x = fill.min_x; x <= fill.max_x; x++)
destrow[x] = (UINT16)color;
}
================
However, each rows of the final bitmap will be the same. So I modified this
simple assigned to work as follow :
1) fill the first row one pixel at a time
2) fill all the other rows by copying the first one.
This makes us use memcpy instead of a hard coded loop for most of the
filling process.

Subject: More naomi ...
Hi.
This patch shows the contents of the framebuffer if the 3d accelerator is
not used so that now the atomiswave logo and messages are shown (if you
wait enough).
Removes a maple bug (no more strange messages in cvs2gd).
Improves documentation of the communication registers with the dimm board.
And if DEBUG_VERTICES is defined as 1 the vertices sent to the tile
accelerator are collected and then drawn connected by a segment to give a
wireframe-like view of the scene.

Subject: 8080 bug
To fix this bug : http://mametesters.org/mantis/view.php?id=2322
a part of my code should be removed.
It seams that this feature I have added is only available on KP580BM80A (Russian clone of this processor).
So until I make a new patch (that support this clone processor) please apply this to fix MAME drivers.
Thanks,

Subject: [patch] More static qualifiers
Hi mamedev,
Another static function update from yours truly, almost entirely
affecting code added in the last few months to MAME. The fixes are
the usual lot, changing enum definitions so they aren't declared,
decorating dead code/declarations with #if...#endif, and of course,
adding static where appropriate. In addition, I fixed a bunch of
UNUSED_FUNCTON symbols to be spelled correctly (I didn't introduce
this).

enclosed please find a patch which makes non-static two pointers to i/o handlers and includes them in megadriv.h. This makes possible for external drivers (in particular MESS genesis emulation) to define elsewhere their own input handlers and to feed them to the megadriv.c routines.
