Please note: regression testing is in progress, but the first round
of glaring regressions have already been taken care of. That said,
there is likely to be a host of regressions as a result of this
change.
Also note: There are still a few rough edges in the interfaces. I
will try to clean them up systematically once the basic system is
working.
All sound chips are now proper devices.
Merged the sound chip interface into the device interface,
removing any differences (such as the whole ALIASing concept).
Modified every sound chip in the following ways:
* updated to match the device interface
* reduced read/write handlers down to the minimal number
* added the use of get_safe_token() for ensuring correctness
* other minor cleanup
Removed the custom sound device. The additional work to just make
custom sound cases into full devices is minimal, so I just converted
them all over to be actual devices.
Vastly simplified the sound interfaces, removing the ghastly
sndti_* business and moving everyone over to using tags for
sound identity. sndintrf, like cpuintrf, is now just a header
file with no implementation.
Modified each and every driver that references a sound chip:
* all memory maps explicitly reference the targeted device via
AM_DEVREAD/AM_DEVWRITE/AM_DEVREADWRITE
* 16-bit and 32-bit accesses to 8-bit chips no longer use
trampoline functions but instead use the 8-bit AM_DEVREAD/WRITE
macros
* all references to sound chips are now done via tags
* note that these changes are brute force, not optimal; in many
cases drivers should grab pointers to devices in MACHINE_START
and stash them away

Go 2000 [Angelo Salese]
====================================================
Also moved go2000.o to suna.a in the mame.mak, because I believe that should stay there.
Now I'll try to fix the spriteram (even though it seems hard to RLE it, this game hardly uses it)...

TomCat (prototype) [Mariusz Wojcieszek]
There are still some small issues (complete list in driver), if somebody with more experience with Atari and/or vector hardware wants to take a look, feel free.
* Added complete reel emulation (thanks to Luca, Angelo and David drivers
studied to better understand hardware similarities).
* Press T to toggle amuse game, used to mask gambling activities.

Jackie [Mirko Buffoni]
- Created custom module for run sounds. Running the discrete sound system at 480KHz was not really optimal.
- Reviewed parts list, schematics and pcb pictures
- Brought mario run sound in line with recordings from Smitdogg
- VCO voltage needs to be 0V for this to happen. Verification outstanding
- Capacitors needed some ageing applied as well. To be removed once the VCO issue is clarified.
