Well here is some initial rom loading, gfx decode, palette decode.
I haven't mapped the CPUs yet, but I imagine it will end up using mostly
the home data code in the end (although that seems to have game specific
code for a lot of games anyway, so there are probably some issues with
that driver)
You can check this in for now, and it can be returned to later.
Types are pretty much unified now.
Multiply operations are handled by eminline.h.
Divide operations were just silly in macros.
64/32-bit combination/extraction macros moved to osdcomm.h and renamed.
Also fixed compile errors in recent 68k changes.
- Added working PMMU address translation (not feature complete, but sufficient
to boot several 68030 Macs in MESS)
- Fixed up disassembly of some PMMU instructions
- Added "68020 with 68851" CPU type

I'm trying to get the HazeMD code running again (by request, and so
that
I can look at fixing some of the bugs that have surfaced, including
ones
which affect MAME)
This shuffles a bunch of stuff around in order to help with that
process, I've also killed off some old megaplay code which wasn't
really
needed anymore, and used the newer code instead.

Othello (version 3.0) [Tomasz Slanina, Stefan Lindberg]
This system is based on a custom CPU. Graphics are decoded but only 2 bitplanes hooked.
All the needed devices are in the driver, but commented out till can properly decrypt the program ROMs and identify the CPU.
About the encryption scheme, see the driver notes about my findings.

Amatic Unknown Slots Game [Roberto Fresca, Team Europe]
Multi Game I (V.Ger 2.4) [Roberto Fresca, Team Europe]
Multi Game III (V.Ger 3.5) [Roberto Fresca, Team Europe]
Fixed a register naming issue in the MIPS core [Harmony]
Numerous SuperFX updates: [Harmony]
- Hooked up RAM and ROM buffering
- Inlined several more functions
- Removed debug spew
- Added the ability to define an external IRQ line callback, and hooked it up to the 65C816
- Fixed flag calculation for HIB opcode
- Hooked SuperFX chip up to the SNES machine driver
* Fixed the coin counters.
* Documented all the output ports.
* Added a scheme with descriptions for every existent port.
* Added full lamps support to naroutp, naroutjp, naroutrh and naroutpn.
* Created lamps layouts for 11 and 12-lamps scheme.
* Rerouted some inputs to mantain the inputs layout.
* Renamed some inputs to match the text with the real cab buttons.
* Removed the imperfect colors flag from the existent sets.
* Added 2 different control panel layouts to the source.
* Updated technical notes.
- added unidasm to the tools build
- split the disassemblers out of libcpu and into new libdasm
- ensured the disassembly entry points for all disassemblers are
in the source file for the disassembler (sometimes new generic
versions were created)
Still needs command line options and file loading, but the
fundamentals are present, and it links.
Colorama is a standalone game driven for 1x VGA board plus a mechanical arm.
Roulette is just the bet station, since the phisical wheel has its own controller. Each roulette has 10/15 stations.

Colorama (english) [Roberto Fresca, Angelo Salese]
Roulette V75 (spanish) [Roberto Fresca, Angelo Salese]
- Split YM2612/3834 to a separate file to avoid disturbing other OPN chips
- SSG-EG, envelope, LFO, and CSM behavior all improved to better match
tested behavior on real YM2612 chips
I have done Intel 4004 implementation, here is a patch (it also
contain a POC driver for 4004 Nixie tube clock, that runs under MESS).
4004clk is artwork file, and roms file contain needed roms (just rename ZIP).

Miodrag

* Full Inputs.
* DIP Switches.
* Simulated spark-watchdog circuitery.
* Demuxed custom port.
* NVRAM support.
* CPU clock derived from #defined crystal.
* 8000-8007 Output ports.
* Coin related counters.
* Sound components and trigger found at 8000-8003, bit2.
* Full lamps support.
* PCBs layouts & technical notes.
The 4 games are fully playable. Sound seems to be discrete, so the circuitery need to be traced.
Colors are still wrong.
