* machine/rescap.h: Implemented audio potentiometer law.
Used it in oberheim/dmx.cpp and linn/linndrum.cpp.
* machine/rescap.h: Function should not be a constexpr.
Also avoiding pow in constexpr constants.
* apple/rbv.cpp: Send blue channel to all outputs when a monochrome
monitor is connected.
* apple/rbv.cpp: Implement device_palette_interface rathr than using a
separate palette device.
* apple/rbv.cpp: Derive 60.15 Hz timer and pseudo-VIA clock from clock
input.
* apple/maciici.cpp: Derive clocks from RBV clock crystal.
-docs: Link more configuration options to their descriptions.
* bus/snes/st018.cpp: Add primary support of ST018 coprocessor
moritas2 now boots, but still hangs at in-game.
* bus/snes/st018.cpp: Fix CPU latch accessing
This is pretty hacky - it uses hard-coded parameters to give timing that
would work for each monitor. I have no idea how the CRTC is actually
configured.
* cpu/drcbec.cpp: Interpret index operand for load/store instructions as
a signed value for consistency with other back-ends.
* cpu/drcbec.cpp: Honour alignment rules when packing immediate values.
* cpu/drcbex64.cpp: Don't special-case SEXT with an immediate source -
the simplifier takes care of this.
* cpu/drcbex86.cpp: Be explicit about preserving flags in load/store
instructions.
* docs: Added a couple more UML data movement instructions.
* 6522via: Don't generate a signal on PB7 when the timer 1 latch is
programmed with 0.
On the Victor 9000, the clock for the audio codec is generated by a
via6522. PB7 is connected to the codec's clock input. Non-speech
sounds (e.g. beeps, musical notes) are produced by outputting a cyclical
waveform from the codec, with the pitch determined by the frequency of
the codec clock.
Software running on the Victor 9000 has been observed to attempt to
silence the audio by writing 0 to the T1 timer latch (not by turning off
continuous mode or PB7 output). With the emulated via6522, this resulted
in a high-frequency clock signal being output on PB7, causing a
high-pitched squeal whenever notes are not being played.
From this observed behavior we could infer that the original 6522 HW
does not output a signal on PB7 when the latch value is 0, and that the
Victor 9000 software was relying on this behaviour to silence the audio
output (one would have to assume that the real hardware didn't produce
a squeal).
* mc6852: fix various transmit-related issues which were preventing
victor9k Audio output from working.
The expected behavior of mc6852 is to write the data received in the
FIFO register serially via tx_data_callback(). However, this was not
implemented, and the only way data in the transmit FIFO could be
removed and transmitted was by calling get_tx_byte(), and to then
serially transmit the data by some external mechanism.
Only m68sfdc.cpp calls get_tx_byte(), so it's hard to see how any
other device using the mc6852 would have been able to transmit data.
Software running on victor9k attempting to play audio would hang,
since it would block waiting for the TX FIFO to empty. With these
changes, Victor 9000 audio playback works as expected, with the data
getting sent serially to the Audio codec.
In order to avoid breaking m68sfdc, a new API call is added to allow
data to be sent the "old" way. m68sfdc now calls
set_tx_pull_mode(true), to get the previous behavior. As I understand
it, other devices using mc6852 must be broken, and would need to
be revisited.
* victor9k: complete Audio support, adding a low-pass filter after
the HC-55516 codec. Mark victor9k Audio as working.
* cpu/drcbearm64.cpp Interpret index operand for load and store
instructions as a signed 32-bit value for consistency with x86-64.
Moved code to interpret load and scale the index for integer
load/store to a helper function to make it easier to update if it
needs changes or fixes.
* cpu/drcbearm64.cpp: Use and/orr to set carry flag directly rahter than
using an intermediate register when both operands of a CARRY
instruction are immediates.
* cpu/drcbearm64.cpp: Fixed incorrect operand type assertion for FREAD.
* cpu/drcbearm64.cpp: Use less verbose asmjit helper functions for shift
operations and addressing modes.
* cpu/drcbex64.cpp: Interpret index operand for floating point
load/store as a signed 32-bit value for consistency with integer
load/store.
* cpu/drcbex64.cpp: Guard against any possibility of load and store
instructions altering the flags.
* cpu/drcbex64.cpp: Reduced copy/paste in floating point load/store
instructions.
* cpu/drcbex64.cpp: Cleaned up some casts between integer types with
differing size and signedness.
* docs: Added reference for UML flow control, data movement and emulated
memory access instructions.
* cpu/uml.cpp: Truncate immediates to size for a few more instructions.
* cpu/uml.cpp: Added SPACE_OPCODES since it's a well-known address space
now.
* cpu/uml.cpp: Removed SCALE_DEFAULT. It's unimplemented by back-ends
and unused by front-ends.
* cpu/uml.h, cpu/drcumlsh.h: Less confusing names for parameters to read
and write instruction generators.
* cpu/drcbex86.cpp: Templated 64-bit multiplication helpers on the
zero/sign flag source, cleaned up casting pointers to integers.

* model2: improve z-sort and clipping
Polygons in later windows are always drawn after polygons from earlier windows, regardless of z value.
Four planes representing the visible frustum are now used for polygon clipping; it is no longer necessary to add 1.0 to z during projection.
* model2: only reset the triangle z value at the start of the frame
Zero Gunner uses z value from previous object for enemy bullets; resetting z values leads to them not being visible
Setting master z-clip value to 0xFF disables z-clipping according to Model 2B-CRX manual
* Added support for reference current (multiplying capability).
* Added support for voltage output.
* Added support for streaming reference current.
* Used those capabilities in oberheim/dmx.cpp and linn/linndrum.cpp.
