Motorola MC6802 evaluation kit. This emulator implements the Keypad and the
LED display, and the MEK68R2 CRT and parallel keyboard interface with support
from the D3BUG2 ROM, and the RS232 terminal support using the MEK68IO and with
support for this also included in the D3BUG2 ROM. Much of the monitor commands
appear to operate properly.
* MEK6809D4: new machine
Motorola MC6809 evaluation board. This emulation implements the keypad and LED
7 segment display, the RS-232 terminal interface, and the MEK68R2 MC6845 CRT
and parallel keyboard interface. The RAM and ROM banking is not yet
implemented but most of the D4BUG monitor commands are supported.
* MEK6802D5: new machine
Motorola MC6802 trainer board. This emulation implements the keypad
and LED 7 segment display, and the RS-232 terminal interface even
though there is no monitor support for it. All the D5BUG monitor
commands appear to be working.
* 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"
* 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.

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
