appropriate, and to keep all global variables hanging off the
machine structure. Once again, this means all state registration
call sites have been touched:
- state_save_register_global* now takes a machine parameter
- state_save_register_item* now takes a machine parameter
- added new state_save_register_device_item* which now uses
the device name and tag to generate the base name
Extended the fake sound devices to have more populated fields.
Modified sound cores to use tags from the devices and simplified
the start function.
Renumbered CPU and sound get/set info constants to align with
the device constants, and shared values where they were perfectly
aligned.
Set the type field in the fake device_configs for CPU and sound
chips to a get_info stub which calls through to the CPU and sound
specific get_info functions. This means the device_get_info()
functions work for CPU and sound cores, even in their fake state.
Changed device information getters from device_info() to
device_get_info() to match the CPU and sound macros.

Subject: Another 8080/85 change from me
Hi Aaron,
I have noticed that there are some problems in interrupt handling in 8080 implementation. Thing is that there are some cases that made a problem while implementing one
computer emulation. Thing is that there is same computer with Z80 and 8080 cpu and ROM's are same, but interrupts were not triggered. So I have searched and found
two problems fixed with this patch.
1. previous implementation cleared interrupt enable bit on interrupt trigger which is wrong since interrupts should stay enabled
2. serve interrupt number was not cleared after interrupt is executed, so if same one is triggered it will not be catched.
I have tested with 8080 MESS drivers, and picked some of MAME drivers using 8080 and 8085, and there were no bad things found.
Regards,
Micko
recent cpu core changes. Specifically, it adds a fake device
implementation similar to the one the cpu cores were using in 128u3
(i.e. it only provides the machine pointer and the token), and makes
some interface adjustments aligned to 128u4 (i.e. adding
snd_class_header, adding get_ to various getter functions). The
primary benefit of this change is the removal of "deprecat.h" from 23
sound cores. I also adjusted ui.c to stop calling sndnum_clock and
access the clock data similarly to how it does the cpu clock data.

Hi mamedev,
Some global state needs to be zeroed to fix this mametesters bug.

02683: Pressing F5 while running debugger causes access violation
02669: pandoras: music tempo is too fast
02691: Some drivers with z80/ay8910 Audio: Audio tempo has changed
Also fixed debugger memory leak.
Added a number of new cputag_* macros to cpuexec.h.
To fix this, I had to break old INP files. While I was in there,
I added corefile support for compressing/decompressing data on
the fly, and enabled it for INPs, meaning the newer format INPs
are output and processed compressed.
Added the concept of 'subviews' to the debugger views. The core
now creates a list of possible subviews, and the OSD can select
between them. This removes code from the OSD that was previously
required to find all possible memory and disassembly views.
Added machine parameters to debugger console output functions.
Fixed some oddities in the memory view.
Moved globals to hang off of the machine structure.
Fixed bug where the visiblecpu was not updated immediately upon
a break.
Important note for OSD ports: the get/set property functions have
been retired for debug_views. Instead, there are specific functions
to perform each get/set operation. In addition, the format of the
update callback has changed to pass the osd private data in, and
the update callback/osd private data must be passed in at view
allocation time. And osd_wait_for_debugger() now gets a CPU object
instead of the machine.
Removed extra debugger tracking for address spaces and added some
of the useful data to the address_space structure. Updated all
debugger commands and views to use CPU and address space objects
where appropriate.
Added new memory functions for converting between bytes and
addresses, and for performing translations for a given address
space. Removed debugger macros that did similar things in favor
of calling these functions.
Rewrote most of the memory view handling. Disasm and register views
still need some additional tweaking.

It should also be noted that many games using this chip are clipping at the moment. This is something that might date back to when sound mixing was upgraded to 32-bit. It is sensible for the 6295 emulator to output at this level because it ensures that bits of precision are not lost, so the mixing levels in the drivers should be adjusted to avoid clipping.
