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()

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
