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.

This is based on an MCS-51 core, like the MK3 bootleg. They are
clearly based on the same code, so the MK3 bootleg was moved to
this driver.
* 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

* There is no longer a concept of "layers" - there are only screens and elements.
* Elements are now instantiated with <element ref="...">
* Screens and elements can have explicit blending mode specified with blend="..."
* Default blending mode for screens is "add" and default for other elements is "alpha"
* Other supported modes are "none" and "multiply"
* This removes the options to enable/disable layers individually - use views instead
* Legacy layouts can still be loaded, and support won't be removed for at least a year
The current artwork model is over-stretched. It's based on a Space
Invaders cabinet model, and isn't applicable to a lot of the systems
MAME emulates now. The fact that MAME has to switch to an "alternate"
mode to deal with games like Golly! Ghost! without requiring pre-matted
bitmaps shows that the Space Invaders model wasn't even adequate for
general arcade use. It shows in that for a lot of the systems that
heavily depend on artwork, people just seem to randomly choose layers
for elements until they get something that works. Also, the fact that
MAME will switch to an alternate (Golly! Ghost!) mode depending on the
combination of elements is a trap for people learning to make artwork.
There are cases that the current approach of implying the blending mode
from the layer doesn't work with. Examples include LEDs behind
diffusers (requires additive blending for layout elements), and mutliple
stacked LCD panels (requires RGB multiplication for screens).
For configurability, it's now a lot easier to make multiple views using
groups. For example, if you want to make it possible to hide the
control panel section of your layout, you can put the control panel
elements in a group and create views with and without it.
I will gradually migrate the internal artwork to use the new approach.
I have an XSLT stylesheet that helps with this, but I'm not comfortable
adding it because it isn't a complete solution and it still requires
manul steps.
I wanted to get the re-worked pointer handling done sooner so I could
push them both at the same time, but unfortunately various things have
prevented me from progressing as quickly as I wanted to. Sorry guys,
that stuff's going to have to wait.
* move princ out of prestige.cpp (it should have never been put there) and into a new driver
fix graphic alignment on the salter gym machines, also promote htem both to working (the hang I saw before on cycle doesn't seem to happen now)
made a note in redclash.cpp about possible sets needing rearrangement
note, princ uses a F2MC-16L based CPU, I don't believe we have a core, but there are plenty of docs available should somebody want to write a disassembler at least.
* reparent the RedClash sets, it appears to be a Kaneko game (Cat logo in the corner etc.)

Gals Panic (Modular System bootleg) [Juan Romero, Recreativas.org, ClawGrip, David Haywood]
these things are *ugly* from a hardware perspective (massive 6 board stack just for Gals Panic with many, many code hacks to work around hardware changes) so I felt it best to create a new driver with the background bits copy+pasted; the sprites + sound system specific to these bootlegs will need adding.

* 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.
Eventually, the svg should be used instead of the pre-rendered ppm.
I'm a little afraid of the performance impact of the 3840 outputs
though, so one thing at a time...
- 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.
