The idea is to create extra work if a driver wants to use these and hopefully
gives an incentive to look for an alternate solution

Subject: [patch] Fix C4305 warnings, other MSVC tweaks
Hi mamedev,
This patch is a bit of a potpourri. It is the result of enabling most
of the suppressed warnings when using MSVC compilers and seeing what
issues arose with different compilers (I used 70,71,80,90). Two of
the warnings were judged to be useful to enable and methodically fix.
Some issues spotted by the other warnings were also fixed.
1. Fixed issues flagged by MSVC warning C4305 (type truncation).
Almost all of these are harmless double->float narrowing in
initializers, but one warning spotlighted a bug in segasyse.c, where
code to use a higher sprite number had no effect due to the
insufficient range of UINT8.
2. Removed /wd4550 for VS7/VS71 compilers (expression evaluates to a
function which is missing an argument list). There are no cases of
this warning currently, and if there were they would most certainly be
bugs. This also allowed the warning suppression lists to be remerged
for VS7 and VS2005.
3. Decoupled intrinsic support decisions from PTR64 in eivc.h.
4. Fixed some VS7-specific issues (OPTIMIZE=0 at least compiles now).
That compiler doesn't support "long long" or "ll" (rsp.c/dkong.c).
5. Added a missing case statement in sm8500d.c. Noticed while
reviewing dead code warnings.
6. Replaced a number of static constants with an enum in sidenvel.h.
This is unrelated to the rest of this patch, but it was overdue to be
done.
- Changed the Berzerk driver to set the S14001A clock as per the schematics. This proves that the schematics are correct and the comment suggesting the contrary can be removed.
- Correct colors, perhaps not the background, but probably is
- Added some sound
- Marked it NOT_WORKING, due to the (still) missing 3rd gfx layer that makes it impossible to pass the 2nd level. Don't suppose anybody has a PCB? It would be helpful even if I knew what I was supposed to be seeing
- correct colors -- in places different from the manual's description, but matches the flyer perfectly
- added speech
- fixed AY-8910 sounds
- odds and ends
- for now, broke Demon Eye X, but I wanted to get this out
- Removed VIDEO_START_CALL(generic_bitmapped) from jpmimpct. By the way, Clueo has a bug where the screen is not cleared properly obscuring instructional text. This happens after the demo mode takes a photo of the 'body'
- Final pass on single-stepping behavior [SGINut]
- Corrected VRCP element lookup [SGINut]
- Corrected unaligned DMA behavior [Ville Linde] (Ville, do you mind that I submit this?)
ROMs were downloaded from softwarethis.com and uploaded to /roms/current/n
One program ROM is different, which adds an additional screen in service mode. I'm sure there are other differences as well.
I would have added the PAL dump, but it's all 0's, and I'm guessing that isn't correct.
Documents various priority issues as being original game bugs, and makes note of a missing alpha effect.
These notes will likely live in a new bug database someday, but were added to the driver so they won't be lost in the short term.
If it's whatsnew worthy, credit Guru for his time spent testing.
- cleaned up and merged ninjakd2, mnight and omegaf drivers into a single driver
- added flip screen support to all games
- fixed sprite overdraw mode:
- ninjakd2 congratulations screen (e.g. stage 3) shows japanese characters which were previously missing
- in ninjakd2, at the beginning of a level items are visible during the initial fade in. I'm not sure if this is correct but the other effects wouldn't work otherwise
- in mnight attract mode, when the big ship is firing the other sprites no longer leave trails
- in mnight at the end of a level the screen is slowly filled with balls and then slowly cleared to begin the following level. Same effect in the death sequence during attract mode.
- added proper computation of sprites to be drawn taking into account double size sprites. This fixes sticking shots in mnight without need for a hack.
- lowered ninjakd2 PCM playback rate to 13020 (from 16000). This seems to sound better and is a round division from one of the master clocks.
- removed ROM patch that was used to avoid the input protection in omegaf, added a rough but effective protection simulation.
- corrected some dip switches
- hooked up sound cpu reset line
- simplified ROM loading for the older games swizzling address lines in driver init.
- Emulated external OR circuit for all drivers using the PIA chip. This used to be internal to the PIA emulation, but, in fact, this is external logic. The PIA has two seperate INTA and INTB out lines. This fixes at least PlayBall

Updated drivers accordingly.
Major cleanup to the ddragon driver:
- improved video and interrupt timing
- consolidated common memory maps and input ports
- added save state support
- correct clocks
Previous checks would not catch modifications in DRIVER_INIT or MACHINE_START calls.
Also changed one of the cheat calls back to using more generic switch detection so they can be triggered via joysticks.
Changes:
- Re-fixed RSP single-step activation behavior
- Reading the RSP PC returns only the least significant 12 bits
- Fixed flag behavior when read out via CFC2
Oh God, why Nintendo, why? Why make the RSP immediately stop when the main CPU sets single-stepping, but have the RSP execute one instruction before entering single-stepping mode when it sets it on itself? "You manaics! Damn you! God damn you all to hell!"
Changes:
- Initialize RSP registers to 0 in lieu of mame_rand
- Re-fix RSP single-stepping mode when set by a CPU other than the RSP
* 8085 has an internal clock divider by 2. Changed i8085.c to reflect this for I8085. I8080 still at 1.
Games using I8085:
* Changed clock to reflect internal clock divider now in i8085.c
* Added some FIXME: comments where clocks for I8085 are outside specs
Also note that there is no analog sound. Apparently the sound is similar to the regular Space Invaders sounds. The Guru has the board out and hooked up if anyone wants to take a stab at getting the sounds going in this game.
Back to fixing some bugs...
Quite possibly the most useless RSP change I'll ever make, given that no game should ever be affected by these changes. But, eh, accuracy. Apparently only the accumulator registers are initialized to a non-random value on power-on, and apparently the RSP executes exactly one instruction before kicking over into single-step mode when it's set in the status register.
- Fixed accumulator state on powerup by testing against real hardware
- Fixed single-step behavior by testing against real hardware
Added new clone "Player's Edge Plus (XMP00006) Multi-Poker"
Increased DUART memory size
Minor white space clean up & commented the rom defs with game names.
The system 10 & 12 clock speeds have been raised as they run on an upgraded chipset.
All clocks are currently set to divide by 2 externally, I don't know if this is correct.
The clock is also divided internally as we have no wait states, incorrect dma timing, no gpu timing, no dma bus stealing and no gte timing.

Verified and changed cpu frequencies and oki m6295 pin 7 on the

Asuka&Asuka, Cadash, Equites h/w games and sound board, F1GP, Super
Formula, Gladiator, Ping Pong king, Great Swordsman, Irem m52 sound
board, Tropical Angel, Explosive Breakers, Magical Crystal, Mad Gear,
Roller Aces, Chinese Hero, Simpsons, Golfing Greats, Time Pilot 84.
Updated Xtal.h to use new OSC values found on Great swordman, Gladiator
h/w and Equites sound board.
Updated informations in Equites.c for the sound board
- 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.
changes P3 & P4 Start of Grand Striker 2 to itp_unknown
as there is no P3 & P4 start buttons.
This addresses gstrik20105u4gra however there are several
games that map the service key twice through out the
driver so it's not really "fixed" as far as that's
concerned
* added equivalence circuit for Sanyo EZV audio amplifier
* Set DK_C159 = 0 to avoid over-aggressive high-pass filter. Solely based on observations.

* Added define DK_NO_FILTERS to turn of DAC filters and post-mixer filters for debugging
"armwrest: Subsequent bonus rounds (After rounds 5 and 9) are unplayable because of missing money bag sprite."
the other part of the bug report is out of date, the screenshot doesn't match MAME's current behavior. The finger still appears cut off, but this is intentional. I suspect the bag placement is still slightly incorrect and that it's meant to look like the finger is hidden inside the bag material.
I think further improvements would require studying the actual board / schematics to improve the zoom emulation.

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.
Reversed ROM set names of Cuebrick World and Japan versions
Changed some function names to reflect parent set
cuebrckj0102u5gre doesn't happen (I didn't fix it)

* combined memory maps
* statics in mario_state struct
* fixed save state issues
* combine sh_* writes into one routine
The skid sound is different from the samples. Reducing the LS123 capacitor by 40% will give the same sound, so I assume this is due to capacitor aging on the board the samples were recorded.
Added code to debug 64-bit builds to allocate all address space below 4GB to help find 64-bit errors.
Added environment variable OSDDEBUGMALLOC which, if set, explicitly overrides the debug malloc debug settings.
Added environment variable OSDDEBUG4GB which, if set, explicitly overrides the new 64-bit address space allocations.
(Sadly this is necessary due to my nvidia D3D drivers being 64-bit unclean....)

Fixed icount management in the RSP core which caused it to report negative cycle counts.
Fixes aleck64_0120red and mtetrisc0115u1red.
Added XTAL defines to bfm_sc2.c
There is also a small style cleanup for lvcards.c to remove the AGEMAME
reference which is now invalid.
I would have done the same XTAL definition for MPU4, but despite the
schematics claiming a 6.88MHz
crystal, I hven't actually had a PCB in my hands to check, and it's not
on either of the two lists in xtal.h, so I'm leaving it be.
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.

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.

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
Note: Protection still not understood in detail. Driver only contains "hacks" as workarounds. Consequently, more protection issues are likely to surface in the future.
Besides confirming clocks on some games, I modified:
Aerofighters and Turbo Force sound z80 to 5mhz
Midnight Resitance 68k cpu to 10mhz (20mhz crystal) and modified m6295
clock to 1mhz. Also confirmed pin 7 is high.
Midnight resistance has a lot of slow downs on the pcb too
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).
Verified some cpu clocks of original boards using a frequency counter:
* Changed Success Joe Ym2203 clock from 3mhz to 4mhz
* Changed Pang M6295 clock from 990khz to 1Mhz
* Changed Halley Comet main cpu clock to 1.664mhz (it's not a mistake, the clock is very low)
* 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.
Removed many hacks from both.
A couple of games changed status from GAME_NOT_WORKING to fully playable:
stagger1, redhawk, redhawkb, grdnstrm, spec2k, firehawk (all - former afega.c)
and tharrier/tharrierj(nmk16.c)
invasn looks a lot better now.
Extracted data for lights.
Added backface culling which mostly works but fails sometimes, so it is disabled.
Started on some initial lighting calculations.
