Subject: [patch] Fix 02764: liberatb: [debug] Access Violation
Hi mamedev,
This fixes 02764. When all the CPUs got tags in 0126u2, this driver
ended up removing it's own cpu(!), causing this crash in debug and
similar unhappiness in non-debug.

Subject: Gururin redump...
This diff replaces the bad (likely hacked) Gururin dump with one Guru did yesterday from my cart and I fixed some rom names in Double Axle according to the pcb. Here's the changed roms:

- converted driver to be fully scanlines based using timers
- hooked up interrupts
- updated driver to new video screen raw parameters (based on ddragon.c driver)

* ddragon.diff:
- converted scanline timer to be a device
- corrected M6809 CPU frequencies, they are supposed to be internally divided by 4 but
there's no internal divider in the core
* gstream.diff:
- improved oki banking (educated guesswork, see notes in the driver)
- replaced CPU_EAT_CYCLES hack with CPU_SPINUNTIL_INT because the first cause the video
completely out of sync with audio. I think the game is really so slow on the PCB too
* vball.diff:
- converted driver to be fully scanlines based using timers
- hooked up interrupts
- updated driver to new video screen raw parameters (based on ddragon.c driver)
* xain.diff:
- converted driver to be fully scanlines based using timers
- fixed ID 02742
- updated driver to new video screen raw parameters (based on ddragon.c driver)

Subject: [patch] Update sound core header files
Hi mamedev,
This patch updates all the sound core header files to declare their
SND_GET_INFO functions, which will be needed once the sound cores
become proper devices. It also makes a handful of other header
declaration fixes in emu/sound, and makes one SND_RESET routine
static. Note: votrax.h is a new include file altogether.

Adds some clones.
Adds Cafe break as not-working (it needs the internal CPU rom dumped).
Also added the (commented out) rom loader for the new "Dai Dai Kakumei" dump,
that only differs in rom sizes.

(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 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.)
