Subject: 8080/8085 fix
Hello Aaron,
While working on drivers for some 8080 machines, I have noticed that there are some errors in flags settings in CPU implementation.
I have done fixes and now sending patch for code . Also there are changes to set right timings for both 8080 and 8085 since not all timings are up to documentation.
Regards,
Miodrag
Subject: [patch] Static qualifiers, header file cleanups, and new
include files for MAME
Hi mamedev,
The following two patches improve the use of header files in MAME, and
reduce the number of exported symbols.
The second patch then adds ~30 header files for a number of drivers
that use multiple source files. It consolidated the various cchip
related declarations in cchip.h, and added machine/seicop.h as well.

Subject: [patch] Static qualifiers, header file cleanups, and new
include files for MAME
The first patch adds static qualifiers where appropriate, adds missing
#include statements, source comments and header declarations, as well
as removes dead declarations. The only part that required judgement
was deciding whether audio/galaxian.c declarations should be in
galaxold.h or galaxian.h, it doesn't make sense for them to be
declared in both. This exercise did find a bug, galaxold_init_stars
was declared incorrectly in video/fastfred.c.
Subject: [patch] Fix 01863 mwalk and clones: Crash on multisession
Hi mamedev,
This should fix 01863, a multisession bug with mwalk. There is more
global state that might need zeroing, but for a 64-bit build, this was
sufficient.

Subject: Machine -> machine cleanups
This cleans up the usage of Machine in many of the src/video files.
* fixed adc/sbb so that they don't optimize out ever
* fixed detection of special and/or/xor cases
* fixed GETFLGS opcode so that it doesn't return anything other than requested flags
* changed LZCNT/BSWAP to be more flexible in register selection
C back-end:
* implemented flag variants of SEXT/ROLAND/ROLINS/LZCNT/BSWAP
PPC DRC:
* added more symbols for debugging
* fixed lmw/stmw if rA is one of the loaded/stored registers
* removed unnecessary variables & structure members
* optimized for the XER and CR0 case where XER doesn't need an overflow calculation
*
* changed SPU receive model to a push model; updated drivers accordingly
* added macros for setting the SPU transmit handler and sending bytes
* cleaned up ppc.h
* Renamed peps0716 to its proper name "River Gambler Slots", instead of "Quarter Mania Slots"
* Updated peps0716 to use the proper CAP
* Replaced peps0615 to use a CAP with closer colors (still wrong)

* Fixes 00251: spdcoin: Sound isn't perfect. There are many static pops to be heard, and volume is very low.
* superbon: Change name to Agent Super Bond and Manufacturer to "Signatron USA"
* superbon: Change year to 1985 following information on arcadeflyers.com
* added detection of MMU enablement in 403GCX case
* fixed bug in protection bounds violation detection for 4XX to get ppd
to the "ppc4xx_spu_rx_data unimplemented" message
* fixed conflicting layout (not super happy with the technique...)
x64 back-end:
* added a "hop" around the prolog of the HANDLE opcode to allow fall-through
x86 back-end:
* redesigned stack management to keep the stack at the same 16-byte alignment
PPC DRC:
* fixed parameter ordering for masked reads/writes

SWAT Police [Brian Troha]
New clones added
----------------
Head Panic (ver. 0117, 17/01/2000) [Brian Troha]
SWAT Police is marked as imperfect graphics. I don't think the roms are bad... The driver may need to updated to support the foreground or the foreground isn't correctly mapped
I made the new Head Panic set the parent even though it's older. Beacuse it's by ESD only and is all English.
Added notes about other ESD games and updates some general info
* Added VBLANK IRQ clear
* Added ATAPI IRQ clear
* Tried to add UART IRQ clear but it doesn't yet work
* Most of the games start to show something again with these changes
* Added fast RAM region
PPC DRC:
* Fixed TLB filling for 4XX protection ranges
PC16552d:
* Tried to wire up assert/clear signals for this chip based on guesswork
(anyone want to implement it properly? :)
* reduced address bus width of 4xx series to 31 bits per the
documentation
PPC DRC:
* fixed bug that would jump to incorrect PC after filling the
TLB during a mismatch event
* added explicit address truncation to 31 bits for 4xx series
* added new PPCDRC_ACCURATE_SINGLES option, which removes the
excessive (and very likely unecessary) extra rounding when
performing the "fast" single-precision floating point ops
Konami drivers:
* designated fast RAM accesses for work RAM
* removed unnecessary mirroring
Model 3:
* identified and fixed VBLANK bit in real3d status which was
causing the system to hang at startup
* designated fast RAM accesses for work RAM
53C810:
* changed read/write handles to proper READ8/WRITE8_HANDLER
callbacks so they can eventually be used directly
* changed from tracking "live" registers to tracking "necessary" registers
* genericized register tracking to be more flexible
* added previous instruction pointer to opcode descriptions
PowerPC frontend/DRC:
* cleaned up register tracking implementation
* fixed numerous errors and shortcomings in the tracking
* added support for removing unnecessary XER CA and CR0 computations
* updated UML logging to output new frontend statistics
MIPS3 frontend/DRC:
* tweaked register tracking to match new DRC frontend system
* updated UML logging to output new frontend statistics
Added dumper notes, hardware details and hooked the sound devices.
Moved Euro Jolly X5 to this new driver, and add support for Grand Prix.

Grand Prix [Roberto Fresca]
- Cleaned up the driver following the MAME Coding Conventions.
- Added support to Game 18.7 (Amusement Poker).
- Updated technical notes.

Cal Omega - Game 18.7 (Amusement Poker) [Roberto Fresca]
* fixed DIVS/DIVU opcode so they properly compute SZ flags when requested;
fixes camera wackiness in nbapbp
PPC DRC:
* added support for 4xx protection registers via the MMU
* added TLBH, TLBU, and DEC to the list of registers in the debugger
* turned off "end of transfer" DMA signals in favor of "transfer count 0"
signals; fixes memory-to-memory DMA in fiveside
Added another Xtal and a new machine driver to support Euro Jolly X5 hardware.
This one is based on a Mitsubishi (Renesas) M16/62A 16bit microcomputer.
(256 KB of internal flash ROM + 20 KB of RAM).
