(You can see a mirrored test menu with a few ROM patches now)
(The i860 code has been found and has been deemed "dead simple" by the guy who wrote the unix binutils i860 disassembler, Jason Eckhardt. He also wrote an i860 cpu core in the past and has donated parts of it to MAME. If he weren't finishing up his phd thesis in 2 months, i'd say he'd have finished this driver by now himself :) )
describes the interface, but does not contain any implementation.
All remaining bits of implementation have been migrated either to
cpuexec.c or to debugcpu.c. Specifically, cpu_dasm() is now
debug_cpu_disassemble(), and cpu_set_dasm_override() is now
debug_cpu_set_dasm_override(). Also moved memory_address_physical()
to debug_cpu_translate(), since it was only ever used for
debugging.
Changed all CPU and sound cores to use memory_find_address_space()
instead of cpu_get_address_space(). The former is reliable even
during early initialization when the CPU cores generally need it.
Removed the dummy CPU core and cpuintrf.c.
Changed the core execution loop to directly call the execute
function instead of using the inline helper (which has been removed).
The program ROM has only 3 bytes of difference at offset 0x008b.
Spacecho: 0x008b: call $2929 ; cd 29 29
Spacech2: 0x008b: im 1 ; ed 56
0x008d: nop ; 00
So... spacech2 is avoiding to enter the sub at $2929.
New clones added
----------------
Space Echo (set 2) [Roberto Fresca]
- Hooked the 3x PPI 8255 devices to chryigld and ncb3.
- Reworked the chryigld and ncb3 inputs based on PPI 8255 connections.
- Added the unmapped PSG sound to chryigld and ncb3.
- Some works on their machine driver.
- Some cleanups.
New games added or promoted from NOT_WORKING status

Cherry I Gold (bootleg of Golden Star) [Roberto Fresca]
New games marked as GAME_NOT_WORKING
------------------------------------
Cherry Master I (v1.01) [Roberto Fresca, David Haywood]
(It was doing a double-shift for CPUs with a address shift)
(The bpset command seems to occasionally behave oddly for cpus with address shifts as well. Didn't figure that problem out in the few minutes i looked at it.)

Subject: minor stuff
Hi,
just a small one:
- adds a ATTR_PRINTF in inptport.c
- removes an unnecessary memset in emu/sound/rf5c68.c
So long

Subject: [patch] Add machine/space to some callbacks
Hi mamedev,
This patch widens some machine callbacks to include an object (either
machine or space). I didn't convert these earlier since MAME didn't
explicitly need them, but some of these will be needed by MESS now
that Machine is gone and in general all callbacks need to pass an
object.
~aa
quantum in terms of "frames" (a dubious concept now with multiple
screens and changing refresh rates). Replaced it with a new
MDRV_QUANTUM_TIME(x) which specifies the minimum scheduling quantum
as a time value. Time can be specified as HZ(x), NSEC(x), USEC(x),
etc. Updated all drivers to use this, assuming 60 was the frame
rate (this is not perfect but should work for almost all cases).
Changed MDRV_WATCHDOG_INIT_TIME(x) to automatically prepend
UINT64_ATTOTIME_IN_ to the parameter, ensuring there is no
improper use of this macro and bringing it in line with the
MDRV_QUANTUM_TIME() macro. Updated all callers.
Added new MDRV_QUANTUM_PERFECT_CPU(x) to specify that the minimum
quantum should be enough to ensure that the specified CPU tag
only ever executes a single instruction at a time. This can be
used to explicitly require "perfect" synchronization for drivers
that have multiple CPUs with shared memory. Turned this on for
the arknoid2 driver for now as a test (the interleave on that
driver was already very close to perfect anyway).
