Subject: MAME cheat search engine
This is a diff of my cheat search engine with help of Pugsy.
This is only a first part, not has the same functions of the old search engine, but is better than nothing
I have update the search engine to support search of byte, word, dword
and qword signed and unsigned.
* Routed the whole video RAM access through PPI-2.
(bypassed the handshake lines for now).
* Merged back the noraut machine drivers after the 3rd PPI connection.
* Added Low Level Hopper manual input.
* Added a new machine driver for extended hardware.
It has 2 jumpers that cut the a14 and a15 addressing lines.
* Added Game 7.4 (Gaming Poker, W.Export).
* Added Game 7.4 proper inputs. Game is now playable with full sound.
* Updated games list and technical notes.
New games added or promoted from NOT_WORKING status
---------------------------------------------------
Cal Omega - Game 7.4 (Gaming Poker, W.Export) [Roberto Fresca, Team Europe]
- Inlined a number of functions for possible speed increase
- Removed some memory buffering cruft, to be re-added later
- Fixed behavior of ASR opcode
- With additional MESS-side changes, Stunt Race FX is playable, and Vortex shows much more.
- No more iterations
- The CD4066 internal resistance largely determines sound amplitude. This may vary significantly depending on VCC and type (74HC, 74HCV, CD4066, ...). The current choice makes scramble sound "about right".
As long as I changed the Midway Y-Unit driver I might as well add the outside submission of Narc rev 2.00
New Clones Added
----------------
Narc (Rev 2.0) [Volker Hann, Team Europe]
Adds the Y-Unit version of the Turbo Ninja hack.
Renames the T-Unit to mktturbo and the new clone to mkyturbo
New Clone Added
--------------------------------
Mortal Kombat (Turbo 3.1 09/09/93, hack) [Jonathan Hughes, Patrick McCarron]
There are still sound issues, some of the music doesn't play, eg.
the VS. screen music
( see http://www.youtube.com/watch?v=lz4gY9d7uxw )
as noted in the driver, the green garbage on that screen doesn't happen on the real pcb, it's probably an encoding artifact.
Phil, can you look at the music?
New games added or promoted from NOT_WORKING status
---------------------------------------------------
Shogun Warriors / Fujiyama Buster [David Haywood, Tomasz Slanina, Luca Elia]
- use SOUND_DAC device to "buffer" data and avoid 1 sample updates for discrete part
- this is related to "03401: circusc and clones: Slowdown in attract mode with DIP SW "Demo Sounds=ON"" though I do not consider it a bug, but a implementation optimization.
(hopefully this will make finding a relationship between the tables and the 'finalblock' of data easier)
Added redumped u6 GFX rom, fixes Geisya and Sumo [Guru]
(u5 still needs to be redumped, it has the graphics for the final 2 bosses in it, Phil indicated that the sample roms may also need redumping but I haven't checked myself, this could be problematic because the Japanese version uses some different sample roms, but I'm hoping those ones were eproms, not mask ones and are already ok)
- Fixed disassembly of LMULT/FMULT ops
- Fixed reads using LDW/LDB
- Fixed writes using STW/STB
- Fixed SBC carry behavior
- Fixed GETC ROM access behavior
- Some SuperFX games begin to show things in MESS
Extracted tables required for Shogun Warriors to work [Tomasz Slanina]
Decrypted + verified table data for Shogun Warriors [David Haywood]
Marked 2 graphic roms in Shogun Warriors as BAD_DUMP [David Haywood]
Temporarily added a hack to the collision function to only use the B.Rap Boys code if the game is B.Rap Boys until we have a single function that works with both [David Haywood]
- Indirect addressing was not taking into account special purpose memory mapped locations.
- 'iorlw' instruction was saving the result to memory instead of the W register.
- 'tris' instruction no longer modifies Port-C on PIC models that do not have Port-C implemented.
Also added difficulty DIP to BigTwin

* Corrected CPU clock to Xtal/8.
* Discovered 3 new I/O lines coming from PPI-2, PC0-PC2. They are mixed with the handshake ones.
* Added the READOUT button to noraut12 games.
* Splitted the main machine driver to cover 2 different Noraut systems.
* Added partial support for PPI-2, PC0-PC2 output lines on noraut11 games.
* Figured out other remaining I/O lines.
* Added new handlers to simulate the handshake lines. Still need real support through PPI-2.
* Updated technical notes.
Hi mamedev,
This patch continues deglobalifying the MAME core, this time targeting
sound.c. The first two patches adds running_machine to apis in
sound.h that lack it (the first patch is generated by the perl script,
the second patch fixes some cases it didn't handle well). The last
patch then removes the globals in the traditional way.

Subject: Clones
Found some ROM dumps on the internet that MAME didn't recognize.
kchampa - Karate Champ (US, set 2) - kchamp.c (renamed Karate Champ
(US) to Karate Champ (US, set 1))
strongx - Strong X (Strategy X bootleg) - scobra.c
The bprom for Royal Card Pro v2.0 was verified correct as the current driver listed. Originally the bprom wasn't dumped and one was used from another set.
(NOTE: Apologies if this ruins your previous cleaning, Aaron. The previous machine/kaneko16.c I posted just minutes before you made the version snap didn't have the Shogun improvements).
* Fixed the coin counters.
* Documented all the output ports.
* Added a scheme with descriptions for every existent port.
* Added full lamps support to naroutp, naroutjp, naroutrh and naroutpn.
* Created lamps layouts for 11 and 12-lamps scheme.
* Rerouted some inputs to mantain the inputs layout.
* Renamed some inputs to match the text with the real cab buttons.
* Removed the imperfect colors flag from the existent sets.
* Added 2 different control panel layouts to the source.
* Updated technical notes.
- some more "list-ification"
- No more constraints on number of input and output nodes
- input nodes now make use of a context
Some of these changes are needed to introduce "internally buffered" input nodes going forward. These will use an internal stream to buffer all inputs so that stream_update will always calculate 20ms of samples.
