cpuintrf.c cleanup

Removed some unwanted clamping code from sound core

Adjusted Frogger volume

Changes from Brian Troha

Changes from Derrick Renaud

Added proper watchdogs to
Bosconian, Galaga, Pole Position, Xevious

Fixed Wiggie Waggle crash

Fixed some speaker settings

schaser – updated sounds to include missle effect and
fix dot sounds per schematics.

SN76477 emulation – fixed bug where gain was 3x more
then it should be, causing effects to clip for 2/3rds
of the time.

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

robotbwl – added discrete simulation for footsteps

crash – added discrete simulation for beeper

Changes from Nathan Woods

– Added entries for two MESS specific sound cores

– Changed wavwrite type from ’void *’ type to an opaque pointer
’wav_file *’

– 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.

Changes from Pierpaolo Prazzoli

Super Slam update
– Fixed sprites
– 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
