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
- Added #include of deprecat.h that rely on these contructs
- Removed a bunch of unneccassary #include's from these files
Subject: z80gb cpu core patch
Changes:
- Small timing fixes when leaving HALT state.
- Fixed bug in retrieving Z80GB_SPEED pseudo register.

This patch for the z80gb cpu core also fixes my problems without the
need to recode a lot of things:
- Split the execution of an instruction into separate fetch and
execute phase.
Subject: other frequencies verified
Corrected Diet gogo h6280 clock so that it behaves correctly with
Charles Macdonald fix to the cpu core.
Verified anc corrected frequencies and pin 7 okim6295 on the following
games:
The new zealand story (3 z80 version), Trio The punch, Vandyke,
paradise.c games, Downtown, Shaolin's Road and Twins.
Updated Xtal.h with 1.056mhz resonator from Trio the punch
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.
