- Removed videoram_w, colorram_w and spriteram_w and changed all drivers using it to access RAM directly. Still kept the _r function as some old style drivers are relying on them for mirroring support. Will investigate and address those next
Updated all CPU cores to return a CPUINFO_INT_CLOCK_MULTIPLIER of 1.
Changed the core to actually respect both CPUINFO_INT_CLOCK_MULTIPLIER and CPUINFO_INT_CLOCK_DIVIDER.
Updated a number of drivers to use cpunum_get_clock() instead of Machine->drv->cpu[x].clock.
***** Raw input clock speeds should now be specified for all CPUs in the MACHINE_DRIVER. *****
Removed explicit divisors from all drivers using the following CPU types,
which were already specifying non-1 values for CPUINFO_INT_CLOCK_DIVIDER:
* COP4x0
* I8039/8048 families
* M68(7)05, HD63705
* M6809E
* PIC16C5X
* TMS32010
* TMS340x0
In a few cases, it appears that the divisor was not being used, so I guessed in those cases whether or not
the specified clock speed was raw.

Here's a patch that fixes compile errors when compiling a C++ source file including "render.h"
and "palette.h". C++ (at least g++) does not like typedef's for an enum coming before the actual enum.
While investigating alternate gfx layout schemes, I stumbled across
the fact that some drivers are allocating graphics with one layout and
then decoding them with another (!). There's no guarantee this will
work, but for the drivers that do so (all Konami games), the layouts
are similar enough that it does. A related potential bug is that many
drivers are decoding using the layout provided to allocgfx, not the
layout attached the element returned from allocgfx. If the element
had scaling applied to it, this would be incorrect, but since scaling
is rare these are also benign. It would also be a problem if the
layout data had a different internal representation (which is
something I'm experimenting with), so to reduce the possibility of
coding errors and allow for future changes, I'd like to remove the
layout parameter from decodechar.
So here's two patches, the first fixes the affected Konami drivers to
allocate and decode using the same layouts. It changes the notion of
plane_order and bpp in the functions somewhat to let the start
routines select the appropriate layout, but acceptably so IMHO (I can
clean this up further if there are loud objections). The second patch
then removes the layout parameter from all the decodechar() calls.
I also reviewed MESS to see if it had similar problems and didn't find
any.
Changed and verified frequencies on Ikari Warriors h/w, Tnk3, Hyper Sports, Jackal and S.A.R
Updated xtal.h to support the 13.4mhz crystal found on Ikari warriors and TNK3 h/w
Verified and corrected a lot of frequencies and oki6295 pin 7 on pcbs:
Double Dribble, Chequered Flag, Diet gogo, Boulderdash, Sly Spy, Psycho
Nics Oscar, Captain Silver, Magical Cat Adventure, Raiden, Superman,
Twin Hawk, Vimana, Ghox, Dogyunn, truxton2, Pipi and Bibis, Fix Eight
and Money Money
They were all verified with frequency counter, even the strangest ones
are right.
Cleaned up atarijsa memory maps.
Added save state support to atarirle, and cleaned it up a bit.
Added save state support to atarig1 driver.
Fixed pitfight0109u2gre
Removed hack in setting the timer in the MIPS core, which caused missed timers on the aleck64 games.
Fixed icount management in the RSP core which caused it to report negative cycle counts.
Fixes aleck64_0120red and mtetrisc0115u1red.
This patch fixes the following issue in the 6522 emulation:
- When writing to the ACR register with the timer 1 in continuous
counting mode, the timer 1 value should not be reloaded but keep on
counting.
This fixes the winwork.c and poly(new).c meory leaks in the viper.c
driver. I didn't look at the x86drc.c, because Aaron said it will be
changed soon and there is no need to investigate those leaks at all.
As I wanted to update my own personal TODO about that fix I
recognised it only happens in viper.c as well, so I took a stab at
it. It was just anothe rmissing cleanup function and I also cleaned
up the *_exit() potions/usage of the cores supporting DRC a bit.
0. This patch does minor cleanup to existing layouts, trimming/padding
entries as appropriate and reformating a few layouts.
1. This patch introduces a GFXLAYOUT_RAW() macro, and uses it
throughout. It codifies the requirements for a raw layout in one
place.
2. This patch adds new validation code to the core for some previously
unchecked assumptions about layouts, and reduces the number of
references to the gfx_layout fields in preparation for a change in the
representation.
3. This patch constifies the remaining non-const gfx_layouts in MAME.
It does this by adjusting the code so that the only modification to a
layout ever needed is for the total field, which is then handled by
modifying a stack-based copy of the layout before invoking allocgfx. I
also spent some time consolidating and simplifying the layout code in
konamiic.c.
- removed years from copyright notices

This is an updated version of my earlier ATTR_PRINTF patch. It was
reviewed by Atari Ace to use ATTR_PRINTF properly and fixes even more
format errors. I also reviewed the whole source again and it is now
used in all possible places.
Removed ui_popup(). Drivers should always be using popmessage() instead (has been this way for a while).
Augmented popmessage() so that you can pass NULL to immediately dismiss any messages.

* added Zeus2 save state support
* added preliminary model and quad rendering support for Zeus2
* added support to timekpr for the ZPRAM used on Zeus2
* hooked up ZPRAM in Zeus2 games
* hooked up controls in Zeus2 games
* updated poly.c to ensure it is idle before saving state
The attached patch adjusts most conditional logging in MAME to use the
idiom "do { if (VERBOSE) logerror x; } while (0)". This has the
benefit that the compiler checks the syntax of the logging even in the
case it will be eliminated, and in fact a number of cases here needed
adjustments to compile because of this.
Here is a fix I've done to the Z80 CPU core that removes the increasing
of the R register from each IX/IY related (FD xx or DD xx) instruction.
This corrects the amount the R register should increased to to 2,
instead of 3. Documentation I've read suggests that the R register is
increased by 1 for each instruction with no prefix, and by 2 for each
instruction with a prefix (DD, FD, ED, CB, DD CB and FD CB). This fixes
some protected cassette loaders in the MESS Amstrad CPC driver, and
maybe others, which require the R register to be correct for the next
routine to be decoded correctly. I'd doubt that there is much, if any,
noticeable impact for MAME, as the R register is really only useful to a
program as a simple random number generator (or seed).
I've tested the fix with Pacman, in MAME, and when it comes across a LD
IX,xxxx or ADD IX,xx it will increase R by 2, whereas previously, it
increased R by 3.
Added artifical Z offset of -2 to make the full screen show in crusnexo.
Really fixed TMS3203x interrupt handling.
Added hack to catch invalid SP values during 32031 execution (debug mode only).
* fixed interrupt handling

This patch should complete the addition of static qualifiers to all
MAME symbols that aren't explicitly exported. It primarily handles
generated code (e.g. amspdwy.c), plus a handful of cases I'd
previously missed and some new cases introduced in the last update.
One interesting bit was the discovery that the 32-bit scanline
routines in drawgfx.c are unused. I debated eliminating them but
decided instead to just export them. Various internal drawgfx
functions were conditionally removed by examining a new RAW define,
although one routine (blockmove_8toN_alphaone) was determined to be
dead code.
While investigating constifying MESS, I came across a few core APIs
that were missing const qualifiers which this patch fixes. I also
consted up tx1.c while I was at it.
- cvs games: according to PCBInfos speech chip is TMS5100.
Changed driver to use TMS5100 and "game system operational" now sounds more natural
- removed sound/m58817.*
- added support for multiple coefficients maps to tms5110.*
- added coefficient maps for TMS5100 and M58817 from documented sources to tms5110r.c
- fixed interpolation factors (see tms5110r.c for reason)
- made lattice calculation precision 9bit
- added support for READBIT and LOADADDRESS commands to tms5110.c
- more changes in line with various patents
This small patch makes some minor "code quality" improvements to MAME.
First off, some remaing static/const qualifier missed cases were
addressed. Secondly, a few cases of missing #include "foo.h" were
added. Thirdly, a few global names were modified to make them less
generic/more consistent (voodoo.c, vrender0.c, lethal.c, rungun.c,
zac2650.c). Fourthly, some dead/useless code was removed
(i8051.c,model1.c,romcmp.c).
* Cleaned up zeus wave RAM accessors.
* Changed rendering code to allow for greater parallelism on multicore systems.
* Removed some vestigial zeus 2 hacks.
* Reduced visible area to remove artifacts.
* Made right/bottom vertices inclusive to fix some gapping issues.
* Fixed invasn lightgun offset.
* Marked invasn as playable.
Zeus 2 hardware:
* Fixed ROM loading, added banking support.
* Separated zeus 2 video implementation from zeus implementation.
* Implemented direct pixel accesses; enough to get startup screens to show.
ADSP-2100:
* Properly documented ADSP-2104 internal memory map.
