- Fixed Wiggie Waggle crash.
- Fixed some speaker settings.
- schaser - updated sounds to include missle effect and fix dot sounds per schematics.

- SN76477 emulation - fixes the attack time for one-shot envelope mode.
- Fixed crash in crash, ripcord and robotbwl and added sample support to them.  Samples not currently recorded.

Changes from Nathan Woods:
-------------------------
src/sndintrf.c:
src/sndintrf.h:
    * Added entries for two MESS specific sound cores
src/sound/wavwrite.c:
src/sound/wavwrite.h:
src/sound/discrete.c:
    * Changed wavwrite type from 'void *' type to an opaque pointer 'wav_file *'.
src/cpu/g65816/g65816op.h:
    * This patch fixes a bug whereby the CPU could switch modes without entering the set of functions for that mode. Specifically, if a mode change occurs it will break out of the execute function and reenter the correct function.


Changes from Nicola Salmoria:
----------------------------
- Documented debug mode in TNZS.
- Fixed some bad gfx in Sky Lancer.
- Rebalanced Gyruss volume.
- NMK004 sound simulation.
- playmark.c updates.
- Fixed sprite/tile priorities in World Beach Volley, and fixed SOME priorities in Excelsior - but not all of them, the high score screen is still wrong.
- Found bitmap enable bit, fixes girl pictures sticking in Big Twin and Excelsior, and garbage graphics in Excelsior.
- Added rowscroll support, fixes wbeachvl37b7gre.
- As previously noted, wbeachvl37b16gre could be a genuine bug of the original - I don't see how it could work otherwise.

- Fixed text tilemap colors.
- Fixed text tilemap scrolls.
- Fixed VSync.
- Fixed dips in Sky Lancer.
- playmark.c update.
- Fixed dipswitches in Excelsior
- Tweaked bitmap scroll in Excelsior
- Changed bitmap to be drawn after the fg_tilemap (this is correct in Excelsior and looks better in Big Twin, but looking at the service mode in Excelsior some "good" bits are trasparent).
- Added Continue dipswtich in Big Twin.
