output from -listxml verb. Compatible with Python 2.7 or Python 3.
Requires at least SQLite 3.6.19 for foreign key support.
This serves a few purposes:
* Demonstrating some things that can be done with -listxml output
* Providing a reference implementation for useful queries
* Helping ensure our XML output isn't completely useless
* Providing additional queries over MAME's auxiliary verbs
* Proper glob support unlike the broken implementation in MAME right now
Right now, it's a bit ugly to use. You can only load into a completely
clean database, and you need to manually create the schema. I'll
address this later. The default database filename is minimaws.sqlite3
(you can override this with --database before the verb on the command
line). Loading isn't particularly fast, but query performance is very
good.
Create a database first:
rm -f minimaws.sqlite3
sqlite3 minimaws.sqlite3 < scripts/minimaws/schema.sql
Now you can load it using a MAME binary or XML output (use one of these
options, not both):
python scripts/minimaws/minimaws.py load --executable ./mame
python scripts/minimaws/minimaws.py load --file mame0188.xml
Once that's done you can do queries:
python scripts/minimaws/minimaws.py listfull
python scripts/minimaws/minimaws.py listclones "*cmast*"
python scripts/minimaws/minimaws.py listsource "*mous*"
python scripts/minimaws/minimaws.py listbrothers "intl*"
These work much like the equivalent MAME verbs, but without the overhead
of loading MAME's static data. But there's one already query that you
can't easily do with MAME:
python scripts/minimaws/minimaws.py listaffected "src/devices/cpu/m6805/*" src/devices/sound/qsound.cpp
This will list all runnable systems that use a device defined in any
file under devices/cpu/m6805 or in devices/sound/qsound.cpp (you can
specify and arbitrary number of files or glob patterns). This may be
useful for planning regression tests.
Another thing this does (that gives rise to the name) is serving
information over HTTP. It's implemented as a WSGI, and it mainly uses
GET requests. This means it can run hosted in Apache mod_wsgi, or
cached by Apache mod_proxy, Squid, nginx, or something else. It can
also run out-of-the-box using wsgiref.simple_server components. The
default port is 8080 but this can be changed with the --port option.
Start the web server with the serve verb (stop it with keyboard
interrupt ^C or similar):
python scripts/minimaws/minimaws.py serve
Right now it's rather crude, and doesn't list devices for you. This
means you have to know the shortname of a machine to get a useful URL.
For example, you can look at a driver and see its parent set and the
devices it references:
http://localhost:8080/machine/kof2000n
Or you can look at a device, and see the devices it refereces, as well
as the devices/systems that reference it:
http://localhost:8080/machine/zac1b11142
The links between devices/systems are clickable. They might 404 on you
if you used a single-driver build with broken parent/clone
relationships, but they should all work in a full build that passes
validation.
There's still a lot to do. In particular I want to demonstrate how to
do live DIP switch preview and dynamic slot discovery. But I've already
discovered stuff in the -listxml output that's less than ideal with
this, so it's helping.
appropriate containers, remove misleading const qualifiers, reduce
repeated XML walking.
(nw) Groups aren't parameterised, so they aren't as useful as they could
be (yes, it's on my TODO list). However, it's already useful for
putting a common set of elements in multiple views, potentially at
different locations/scales. See intlc44.lay and intlc440.lay for
examples of the level of copypasta this can eliminate. Be aware that
groups with explicit bounds don't clip thair content, it's only used for
calucating the transform matrix.
These humble 16-pin logic devices were commonly used in 8-bit arcade games to control coin counters/lockouts, IRQ flipflops, graphics banking, slave CPU reset lines, discrete audio triggers, screen flipping, serial EEPROMs and much else. Over 100 drivers and a few bus devices have been updated to use the new implementation, and a great deal of research has gone into documenting the physical location of these devices on actual PCBs in the source. Write handlers have been provided for both orthodox and somewhat less conventional memory mappings.
Incidental to this update, coin counters and/or lockouts have been added to Atari System 1 games, Basketball, Gauntlet, Gyruss, Hana Yayoi, Hole Land, Jr. Pac-Man, Mahjong Sisters, Pooyan, Roc'n Rope, Squash, Thunder Hoop, Time Limit, Time Pilot '84 and many others. This also cleans up coin counter behavior in Sauro and Rally Bike.
(nw) The purpose of committing this change, which has been several months in the making, early in the 0.189GIT cycle will be to allow time for fixing potential regressions; I've fixed a number of drivers that lost sound from this for various reasons (hnayayoi.cpp having missing or garbage ADPCM was particularly painful, since the three games in that driver all work slightly differently), but I can't test all affected drivers exhaustively. @Tafoid, don't bother running automated screen capture comparison tests on this, as many drivers are now expected to have the screen flipped for the first few seconds after reset.
- made ds5002fp store internal ram and sfr registers to nvram as they're battery backed
- this includes the 'configuration' details which are actually programmable, so don't belong in the 'MACHINE_CONFIG' section but rather as part of the default NVRAM
- as the exact format of the NVRAM storage is not known, and as not to break compatibility with the 'wrally' set Gaelco offer these bytes are now configured in the ROM LOADING like default NVRAM. Slightly awkward, but probably the best way.
- made the SRAM (external to DS5002FP, but still powered by the same battery) also save content, some games actually use it to store scores etc. as well as the game code.
- cleaned up the Touch and Go Dallas dump, and added some preconfigured internal RAM so that it actually loads the score data from the SRAM properly
- prepared all other drivers for the adding of the SRAM dumps, removing old 'never going to work' simulation code in the process. To do this a wrapper / interface device for the Gaelco Dallas + SRAM box was created.
out of whatsnew
Alligator Hunt was dumped and works, but not yet added, want to verify on a 2nd PCB first as the process does corrupt some bytes and a couple had to be handfixed, so the only way to know for sure is multiple dumps.
* Fix save/load states in Emscripten build
* Simplified Emscripten integration points
* Moved standalone JS functions to be static member functions of running_machine
* Improved Emscripten main loop
* Use convenience functions for cleaner code
As an added bonus, this now allows for proper shutdown of the running machine when running in the Emscripten environment - previously, attempts to exit the program were just being ignored.
- Merge driver with goldnpkr.cpp source to get working sound (graphics and sound should be identical)
- Add version numbers to set names
- Promote megadpkrb to WORKING (with one caveat)
What works:
* HP85A machine with 16K of RAM
* Capricorn CPU works
* Keyboard works (with minor issues)
* CRT text / graphics modes work (correct speed is not emulated yet so service ROM complaints)
* BASIC is usable
What is missing (and I'll have hopefully working soon):
* HW timers
* Beeper
* Integral printer
* DC100 cassette drive
* Extension ROMs
* I/O modules (especially the HPIB interface so that we can hook up floppy drives)
* Other models in the family (e.g. HP86)
create a uPD78C11 derived CPU type for this purpose, with internal ROM map
use internal ROM map for other uPD78C10 chips as it's always present.
add missing NO_DUMP definitions to various games using C-Chips with correct size etc.
pump megablast through the device code as really all it ever does is bank the c-chip window and test the RAM.
* Implemented front panel mode switches/LEDs and reset switch
* Added skeleton bus for "universal" slots and connected control lines
(nw) Default keyboard mapping is annoying because left shift, Z and X
are used both for typing into the TTY and switching program bank. You're
better off changing the mapping to make it less annoying or using a
socket and talking to it with telnet.
* Renamed to MCS-40.
* Emulated 8-clock instruction cycle, interruptible at any point.
* Converted TEST input to an input line.
* Added SYNC and CM output lines.
* Added support for 4040 CY output, logical operations, extended registers, ROM banking and disassembly.
* Made I/O space mapping more flexible to support the variety of peripherals available.
* Notable missing features are 4040 interrupt and halt, and "program memory" space.
* This turns the current state save feature to a menu; one can still press 0-9, but you can also browse a menu when loading and saving state
* Fixed some issues requested by Vas Crabb
* Updated state menu to support arbitrary character slots
* WIP, transitioned 'entry_char' to std::string
Still need to address Joystick and FR keyboard concerns
* Reimplemented state save support with joystick buttons
* Changed the state menu to be "code driven" rather than "character driven"
When the menu is displayed, it will look at the filenames, and translate them to a visual representation as per the user's locale
* Vas feedback

sound board, completing the tromba circuit
(nw) I'm not sure whether the model works properly or not, but in the
circuit where it's used, I don't think it can work properly with the
current TTL output model. A capacitor is charged by the Q output of a
74LS74 flipflop (U3A) until the voltage passes the Schmitt trigger's
threshold, causing it to reset the flipflop. However, the positive
trigger voltage of the Schmitt trigger is 1.6V, but our TTL output model
has a high output voltage of 1.0V (see nl_base.cpp:89). I realise the
simplified model of TTL logic with high impedance inputs and outputs
behaving as though thery're loaded is convenient and fast to simulate,
but it's not detailed enough for applications like this where
7400-series chips are used in analog circuitry. This is what held me up
last time I tried adding a netlist for this sound board.
- OPENMP refactored. All OPENMP operations are now templatized in pomp.h
- We don't need thread-safe priority queue. Event code updating analog
outputs now runs outside the parallel code.
(nw)
* Tromba (trumpet) sound is not working - requires Schmitt trigger device
* Connecting cassa (bass drum) swamps other instruments so it's disconnected for now
* Mixing melody sound with speech/SFX is not done in netlist (should be)
* Relative levels of melody/speech/SFX are probably still wrong
(nw) A good test case for this is the Money Money driver (monymony).
There's a bit of buzzing on this one as well. The problem with the
cassa could be caused by running into non-ideal characteristics of opams
again (the LM3900 seems to ignore the V+ value supplied to it). When
the netlist library gets Schmitt trigger support, the tromba can be
completed. Unfortunately, the tromba is a key part of the
characteristic sound of these boards, so you really notice when it's
lacking.
(nw) It doesn't work quite right yet. The "Hammer" and "Pest" sounds
are generated by free-running 555/556 timers and gated with LM324
applifiers. For whatever reason, the netlist system produces a kind of
buzzing from the "Hammer" circuit when it's supposed to be suppressed,
and it doesn't think the pest sound should be suppressed completely so
you can always hear it at a low level in the background. The "Cheese"
circuit is a bit weird - either they're using the base-emitter junction
of a 2SC945 as a signal diode, or there's an error in the schematic
(collector is shown unconnected). Connecting this part of the circuit
causes the netlist system to hang, so R2/R3/C8/Q2 are not connected for
now.
