Subject: [patch] Make NBA Jam TE a set
Hi mamedev,
This patch treats NBA Jam TE versions as a set, rather than treating
them as clones of NBA Jam. The treatment of sets varies throughout
MAME, this choice is emphasizing the fact that the games were distinct
from NBA Jam, with different marquees et cetera.

After adding these, I downloaded all manuals for the driver (couldn't find a
Boulder Dash manual) and I validated the DIPs with the manual and ensured that
the service mode (when available) matched up as well. I also added DIP
LOCATIONS for all sets in the driver. There were also a couple DIP items set
up in the source which did not show in the manuals I obtained - so I noted
these facts in the driver.
This .DIFF is based on 0.127u3 sources and resolves MAMETesters Bug #01897.

due to bad roms had a fully working service mode. I also noticed the DIP
locations were well documented on-screen and differed some from the ones in
source. I took the time to read up on how to assign DIPs correctly - but I was
frustrated initially thinking I didn't understand it. I spoke to ETABETA about
this and it seems I picked an uncommon game/driver which doesn't have normal
mapping locations (for whatever reason) and that I'd need to find out what each
value is actually doing. As a result and some work and some more help - I was
able to understand how to do this and reworked the DIPs to what is output in the
service mode for all games (except for Revenger) which did not work enough at all.
While I was there, I added DIP LOCATIONS for all sets. I would assume this
eventually benefit from a PORT_CUSTOM implementation.

Subject: Patch for new dumps
Hi,
I have attached a patch which adds support for the following;
* The "Three Wonders (Hack?)" dump from the EMMA dumping team (I'm not
100% sure of the CPS B-ID this should use)
* The "Marvel vs. Capcom (Euro 980123)" dump by bonky_0013 (this becomes
the parent set).
Regards,
Barry Harris
installing a handler in the SOUND_START function.
02249: All Sets in zn.c: Game Hangs
02248: All sets in m58.c: No sound in game
02241: kncljoe, kncljoea: Missing AY-3-8910A sound effects.

02239: stunrun: No OKI6295 sound.
metadata with pre-decoded frame information. Modified chdman to
automatically produce this for CHDs that are of the appropriate
parameters. To fix up existing CHDs, use chdman -fixavdata on the
CHD.
Modified the laserdisc core to leverage the pre-decoded frame
metadata, which is now required. This improves seek times when
searching and allows the player-specific emulation access to the
VBI data as soon as it would really be available. Changed update
callback timing to fire just before the first line of VBI data
would be read; at that point, the frame selection is assumed to
be committed.
Converted PR-8210 emulation over to using the actual MCU from the
laserdisc player. This MCU controls low-level functions such as
slider position and laser on/off, and receives decoded vertical
blanking data in order to make decisions. Removed old HLE behavior.
Note that the overlay text is displayed via the UI; this is
temporary and will be fixed shortly.
Converted Simutrek-hacked laserdisc emulation to using the actual
MCU from the game, which in turn hands off commands to the PR-8210
MCU. This is still not 100% but is pretty close at this point and
achieves the correct behaviors in most cases.
Fixed Cube Quest overlay scaling to cover the whole screen.
Changed laserdisc video parameters to position the screen area at
the bottom rather than the top, since this corresponds more closely
to standard line numbering.
Extended the vbiparse code to support pack/unpack, and to more
fully document all the meanings of the VBI codes.
Updated ldplayer to support slow/fast forward movement, frame/chapter
display, and separate controls for scanning/stepping.
Added new built-in variable "frame" to the debugger.
Fixed device-based ROM loading to support loading ROMs from the
game's ZIP as well.
Full controls, plus complete DIP switches and port locations. Promoted to working.
This set has adjustable prize.
New clones added
----------------
Hot Mind (adjustable prize) [David Haywood, Roberto Fresca]
- Added new clone: Pool 10 (italian, set 4).
- Improved lamps layout for all games.
- Added Pool 10 pinout and DIP switches info.
- Updated technical notes.
New clones added
----------------
Pool 10 (italian, set 4) [Roberto Fresca]
True world set with World, USA & Canada, Korea, Hong Kong, or Taiwan
Minor clean up of port include dipswitch defs
New clones added

Subject: Several patchlets
ledutil.diff
- checking if memory is allocated before using it is good, freeing what
has
been allocated in the error path is better
and added an empty BIOS driver for it.
Here is a patch file with the following changes:
* Added new Atari System 1 Motherboard BIOS dump from a LSI motherboard
* Added a new ROM dump from a Marble Madness LSI Cartridge
* Changed the hardcoded MHz values in the Cave driver to the XTAL
equivalents
* Updated the Cave driver for the game Guwange with gals that need to be
dumped
* Updated the Jail Break driver with the dip locations
* Corrected the Jail Break driver sound chip from a SN76496 to a SN76489
* Corrected the Jail Break rom names
* Redumped the Jail Break VLM rom dump
* Corrected the Super Basketball Revision H rom dump
* Updated the Super Basketball driver with the dip locations
* Corrected the Super Basketball VLM XTAL
* Corrected the Super Basketball parent/child relationships by making
the
Revision H the parent
* Turned on save state support for the Super Basketball driver
* Updated the Sega System 1 driver with more board information on the
Choplifter bootleg and updated the placeholders for the pals that need
to be
dumped
* Updated the WWF Wrestlefest driver rom names
* Added save state support to the WWF Wrestlefest driver

acceleration pedal now on up/down key.
It makes sense that the "down" key means push pedal down and "up"
means lift pedal up, however I am unsure that this is what the player
may expect.

Subject: [patch] Even more reset/multisession cleanup
Hi mamedev,
These two patches try to reduce the amount of variable in .data, which
usually point to multisession/reset bugs or missing const qualifiers.
The first patch just adds const to a number of items, moving them from
.data to .rdata. The second patch sets other items to zero (moving
them to .bss), adding reset/init code where appropriate.

Found few things not right in 8080/8085 implementation.
1. ANA/ANI instruction, HF flag was not set right because error in calculation of it (missing brackets)
2. 8080 have NF flag always set (it is not used flag but bit is always set)
3. On unused ports/not connected memory values from status word were readed not 00 or FF, that is why I add it as a new internal register, it can also be buffered by some external hardware, so this could help other implementations too.

the driver's memory maps.
Reverted recent changes to MCS-48 core that were very hacky and which crashed
many games. You can now properly override the internal memory map and do
your own banking.
Also fixed 02204: masao: Memory bank error.
- Simulated the MCU communication/protection.
The game seems to work properly, but is hard to win.
I conserved the game flags till we have the MCU decapped,
and emulated properly.
- Added full sound support.
- Added lamps support + layout.
