* minor spelling fix
* new NOT_WORKING machine
Gigatron TTL Microcomputer [Sterophonick]
also add a skeleton cpu core
* Revert Minor Spelling Fix
* Make some fixes
thanks cuavas
* Fix resolution
* gigatron: update cpu device name
* update copyright
* fix part of gigatron disassembler
* Set screen refresh rate
* found a set of all the ROM files, update main ROM name
* Fix cpu.lua
* Whoops
* Update gigatron.cpp
* gigatron: clear execute_set_input
* Update gigatron.h
* Update gigatrondasm.cpp
* Update gigatrondasm.h
* clean up but doesnt compile ffs
ioport.cpp:
* better than 50% reduction in compile time, and better locality for static data
* better encapsulation, const correctness and noexcept usage
* When a switch-type input is selected, show feedback when it's pressed
* If an invalid code is entered (e.g. only negatives) abandon the change rather than cycling default/none
* If an invalid code is entered display a message until the user takes some other action
input.cpp updates:
* constexpr crusade on input_code and input_seq and some very slight optimisation to input_seq
* seq_poll* is a frontend function and had no business being in the core, so it's a utility class now
* seq_poll* now exposes a bit more detail, enabling improved interaction on the UI inputs menu
* global state is reduced a little, but the poll_* functions are still members of the input manager with global state
(nw) The Lua engine has been updated in a way that maintains source compatibility with existing Lua
scripts. This is less than ideal, but it minimises impact. Ideally someone (possibly me) will be
able to expose the input sequence poller helper properly. I tested the changes with the cheat and
autofire plugins and I was able to assign sequences. However I found two issues: it's seems
impossible to assign a more complex sequence than a single key/button in the autofire plugin (i.e.
no AND or NOT conditions, I confirmed this is pre-existing, not a regression), and in both the cheat
and autofire plugins I found it a bit unwieldy trying to enter a complex sequence without live
feedback of the sequence as it's built (this was also applicable to MAME's own input mapping menu
until I added the live display yesterday).
-sun4.cpp: Various changes: [Ryan Holtz]
* Split sun4 and sun4c hardware emulation into separate derived classes.
* Hooked up Sbus IRQs.
* Removed now-unnecessary duplicate MMU code.
-cgsix.cpp: Added VSync IRQ, cleaned up save state usage, and added THC MISC register. [Ryan Holtz]
-sparc.cpp: Renamed MB86901 to SPARCV7, and added a separate class for SPARCV8. [Ryan Holtz]
-bt45x.cpp: Made logmacro.h usage more consistent. [Ryan Holtz]
* Made DIP switch display scale with UI font and improved layout
* Improved analog control display giving an indication of neutral position
* Fixed menu heading sizes not being recalculated after font is changed
* hp80: refactored optional ROM device as requested in issue #5839
* hp9825: refactored optional ROM device as requested in issue #5839
* hp9845: refactored optional ROM device as requested in issue #5839
- Added slot interface for internal expansion boards.
- Added BBC Master cartridge slot interface to allow implementation of more complex cartridges, including Electron cartridge devices.
- Removed Sideways RAM configuration option, to be re-implemented as internal boards.
- Empty BBC Master cartridge sockets return video data on data bus.
* Changed emu_fatalerror to use util::string_format semantics
* Fixed some incorrectly marked up stuff in build scripts
* Make internal layout compression type a scoped enum (only zlib is supported still, but at least the values aren't magic numbers now)
* Fixed memory leaks in Xbox USB
* There can only be one "perfect quantum" device - enforce that only the root machine can set it, as allowing subdevices to will cause weird issues with slot cards overiding it
* Allow multiple devices to set maximum quantum and use the most restrictive one (it's maximum quantum, it would be minimum interleave)
* Got rid of device_slot_card_interface as it wasn't providing value
* Added a helper template to reduce certain kinds of boilerplate in slots/buses
* Cleaned up some particularly bad slot code (plenty more of that to do), and made some slots more idiomatic
This patch gets it running, and splits it into two front ends, one
being a rs232 bus slot so that is can be used as a terminal option. It
adds the MCM66750 character generator, and implements the MC6845 row
update function. Most of the I/O has been worked out with help from
the CT-82 user manual. The various screen formats and the graphics
modes appear to be working and plausible. Printer support has been
added, and a beeper.
- Removed code no longer used
- Add noexcept where appropriate
- split pparser.[c|h] into ppreprocessor and ptokenizer
- smaller optimizations, e.g. use of std::size_t
- fix lint warnings
* hp9825: optional ROM cartridges added (9825b only, ATM)
* hp9825: optional ROMs added to 9825t, added support for banked ROMs
@5c00, separated RAM & ROM spaces in 9825t
* hp9885: added missing post-amble when writing sectors on disk
* hp9825: added acknowledgments to comments (nw)
* hp9825: changes requested by V.Crabb (nw)
* Allow specifying NO_OPENGL manually
* Switch bgfx to OpenGL ES renderer if NO_X11 is specified
* Only link against EGL when NO_X11 is specified on linux, netbsd and openbsd
* Only switch bgfx to OpenGL ES on linux, netbsd and openbsd
* Indentation fix
* Add workaround for imgtool and jedutil failing vs2019 debug builds with /ZI
* No longer allow msvc build to fail
* Enable tools build for travis to make it more useful
* Switch travis to Xcode 11 in order to fix nltool linking failure
* Prefer 64-bit compiler with VS 2019 too
* Setting PreferredToolArchitecture to x64 is not needed, genie puts it into the project files for vs2015 or later
* OPTIMIZE=1 build is faster that OPTIMIZE=0 for some reason. So fast in fact, that TOOLS=1 can be enabled without hitting the 60 minute timeout
* Switch MINGW build to VS 2017 image until appveyor figure out why builds on VS 2019 are almost twice as slow
* Run pacman twice to account for core system upgrades
- solver now uses dynamic allocation on systems larger than 512x512
- fixed osx build
- moved nl_lists.h classes to plists.h
- fixed netlist makefile clint section
- readability and typos
* Sync with bgfx upstream revision b91d0b6
* Sync with bx upstream revision d60912b
* Sync with bimg upstream revision bd81f60
* Add astc-codec decoder
* Rename VertexDecl to VertexLayout
* Rename UniformType enum Int1 to Sampler.
* Add NVN stub
* Fix unused-const-variable error on macOS
* Drop redundant explicit language parameters
buildoptions_cpp are only applied to c++ files and buildoptions_objcpp are only
applied to objective c++ files. As such, hardcoding -x offers no benefit while
preventing overrides (such as one needed by 3rdparty/bgfx/src/renderer_vk.cpp on
macOS) from working.
* Re-introduce -x c++ in places where C code is compiled as C++ to prevent clang from throwing a warning
* Build bgfx as Objective-C++ on macOS
It is needed due to included headers
* Enable Direct3D12 and Vulkan bgfx rendering backends
* Enable building of spirv shaders
* Properly escape /c in cmd call
* Comment out dx12 bgfx renderer
* Honor VERBOSE setting during shaders build
* Only invert hlsl shader XYZ_TO_sRGB matrix for opengl
* Add spirv shaders
* OpenGL ES needs transposed matrix too
* Metal needs transposed matrix as well
* Re-write makedep.py for better performance and better parsing front-end
* Make srcclean deal with kinds of preprocessor abuse I never want to see in real life
(nw) The new parser front-end is better at recognising C++ syntax and
also substantially faster - bootstrapping a single-driver build should
be noticeably quicker. Having a single parser for C++, .lst and .flt
files also gets us a bit closer to making it simpler to create custom
subtargets.
(nw) This has been a long time coming but it's here at last. It should
be easier now that logerror, popmessage and osd_printf_* behave like
string_format and stream_format. Remember the differences from printf:
* Any object with a stream out operator works with %s
* %d, %i, %o, %x, %X, etc. work out the size by magic
* No sign extending promotion to int for short/char
* No widening/narrowing conversions for characters/strings
* Same rules on all platforms, insulated from C runtime library
* No format warnings from compiler
* Assert in debug builds if number of arguments doesn't match format
(nw) Also removed a pile of redundant c_str and string_format, and some
workarounds for not being able to portably format 64-bit integers or
long long.
This will compile, link, and run a driver all the way to the first info screen, provided you use -video bgfx.
However, although there's a valid NSWindow created, it never actually appears on screen for unknown (but likely silly) reasons.
Inputs are not implemented and fullscreen exists but is untried.
* hp9825: fixed a bug in 9825t
* hp9845: TACO driver re-written from scratch, DC100 tape separated into
a new device, various adaptations
* hp9845: "new TACO" renamed to just "TACO"
* Made some experimental work with menghong based HW, allowing crzyddz2 to boot and improving menghong colors;
* Internalize video and audio components inside the SoC;
* Wrote a preliminary UART subdevice;
* Made external video clock to be settable by the host driver;
* spectrum bus : rename beta.cpp to beta128.cpp as the original beta is somewhat different (nw)
* (nw)
* start making a device for the actual original beta disk interfaces (nw)
* flesh out beta stuff a bit (nw)
It appears that it is sufficient to include `-s USE_SDL_TTF=2`, and
emcc links in the SDL2_tff library, and it does not like attempts to
link this twice.
The current Emscripten release is not happy with the use of
"-s ERROR_ON_MISSING_LIBRARIES=0" as a link option, it gives an error
stating that all libraries must now be present, so remove that use.
This leaves a missing 'util' library. This did not appear to be
needed on the few builds I have tried, and this patch avoids adding
this library for asmjs.
* Improved encapsulation between video and machine SoC periperals;
* Split up HWs in individual files where they don't belong to Crystal System HW, makes future development easier;
* Untangled reads/writes to draw/display bankswitches from screen_update, now they can be unthrottled safely;
* Added CRTC screen raw parameters;
* Add DMA hold feature and clear irq on mask writes, specific for P's Attack;
* Improved Cross Puzzle flash loading, currently failing at POST for a SPU error;
nexus3d.cpp: add some preliminary work, currently does some VRender3d pipeline fill with a debug trick [Angelo Salese]
(out of whatsnew)
Some stuff definitely needs fine graining, like removing the few lines that are still necessary to configure the VRender0 from driver files, which I'm gonna do in my next feature branch.
Split out the floppy disk controller from the swtpc09 machine, adding it to
the ss50 interface. The DC5 is compatible with both the SWTPC 6800 and 6809
systems, supporting the 4 and 16 byte I/O interfaces respectively, via a
jumper setting, so can be used on the MAME swtpc and swtpc09 machines. The
DC5, like the DC4, supports double sided and density disks, and claimed
backward compatibility with the DC1, DC2 and DC3.
Split out the PIA IDE hard disk interface from the swtpc09 machine. This
support appears to have been incomplete or to have bit rotten, and has been
updated and tested lightly with FLEX9.
* Enable precompiled header usage in the Visual Studio compiler
But only for libraries emu frontend precompile dasm optional
Also add emu.h include to hpcdasm.cpp
* Include emu.h in some disassembler sources to use precompiled headers
* Remove debug message
The UniFLEX disk format is not compatible with the Flex format. Significantly it
does not use a mix of single density for booting on some double density disks
which makes it simpler - hardware required a new boot ROM to run UniFLEX.
Further, the UniFLEX sector size is 512 bytes versus 256 for Flex, and the
UniFLEX 'SIR' info sector record is completely different to the info on Flex
disk, and the file system format is also not at all compatible.
Thus the UniFlex format can rely largely on the WD17xx format, with an
overload to handle the sector numbering on the second side continuing from the
first side (one feature in common with the Flex format). This gives a quick
'save' capability and shares code.
Support for 8" disks is included as this was the initial distribution format
and the only one found so far.
* gdbstub: added new GDB stub debugger
This debugger can be used to connect to an external debugger that
communicates using the GDB Remote Serial Protocol, such as GDB itself
or many other GDB frontends.
Currently i386 (ct486), arm7 (gba), and ppc (pmac6100) are supported.
* gdbstub: enable GDB stub debugger in mac and windows builds
- Replace additional driver RAM with S-100 bus
- Convert Video Terminal Interface into a S-100 bus device
- Add skeleton S-100 bus device for SSSD disk controller
- dxsdk was missing from includes
- winmm was missing from libs
- narrowing warning was silenced for VS, but not from vsllvm, where it leads to an error in menu_video_options::handle()
* hp9845: fixed handling of optional ROMs (nw)

* Turned on sector interleaving in OS9_DSK and retested.
On Linux, enable Xinput support by default. The Xinput lightgun driver is the
only reliable+accurate method to use lightguns on Linux, we should enable this
by default to reduce the friction for Linux Lightgun users. This should have no
effect on users of Windows/Mac etc.
- it's a newer SoC (with a lot more capabilities, eg rotate, zoom, twice the sound channels)
- it uses an updated unSP core (with some extra opcodes)
also made the modifications needed to allow for extension of the unSP + disassembler once we've worked out what the extra opcodes are.

Before pushing, please check that what you're about to push is sane.
Check your local commit log and ensure there isn't anything out-of-place
before pushing to mainline. When things like this happen, it wastes
everyone's time. I really don't need this in a week when real work™ is
busting my balls and I'm behind where I want to be with preparing for
MAME release.
- added MOSFET model. Currently capacitances are not modelled.
This is a 3-pin model (Bulk connected to Source) with provisions to
extend it to 4-pin at a later stage.
- Add a capacitor generic model which is charge conserving.
Switch netlist to use this model instead of constant capacity model.
- Start putting constants into a central place.
Please expect minor timing differences due to a different numerical
path.
The cmos inverter example illustrates the analog implementation of a
cmos inverter gate. These were used a lot back in the 70s/80s to
generate sinus waves. The model should also be able to better emulate
4066 analog switches.
The addition of a relatively simple capacitor model is planned at a
later stage.
Expect everything from the MOSFET model at the current stage. Wrong
results as well as convergence issues and crashes.
.
A single 64K 2-way set associative cache
Used for both instructions and data
Enabled only for addresses in the first megabyte
Works always in writeback mode
.
It is needed by the nforce motherboard bios that uses it to simulate a
block of ram at address d0000 before ddr ram is configured
* SPG2XX - Make audio emulation a subdevice
(I need to reuse some of it for SPG110)

WIP checkpoint: while I believe it's largely accurate (and very slow), neither jazz nor sgi systems can fully boot yet using this device, so it remains experimental.
This implementation should go away when it has helped identify the improvements required for mips3.
