    • hooked up watchdog, global mute
    • fixed IRQ2 timing
  • segaxbd: tweaks

    • fixed IRQ handling to match schematics
    • hooked up watchdog, sound reset, and global mute

    • reduced interleave on all games except LOF
  • segaybd: tweaks
    • fixed CPU speeds according to schematics
    • hooked up global mute
    • reduced interleave on all games
  • machine/segaic16.c: changed divide-by-zero case to return a value
  • vidhrdw/segaic16.c: several updates
    • implemented Y-board sprite priorities (not fully understood, but seems to work)
    • found missing 8th bit in Outrun/X-board sprite pitch
    • implemented Outrun/X-board road priorities according to logic dump from Leopardcats
    • hooked up road RAM double buffering that was missing for Outrun/X-board
    • disabled direct scanline mode for Outrun road, which doesn't support it
  • Fixed sample playback glitch
  • Fixed othunder sound clipping
  • Fixed Batrider sound
  • Fixed Dream Shopper crash
  • Added sound balancing assistance display to debug builds
  • 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 are not currently recorded.
  • 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

• Brian Troha fixed DIP switches in NMK16

• Philip Bennett made progress on the TX1 / Speed Buggy driver
  • Still To Do:
    • Buggy Boy/Speed Buggy
      • Arithmetic chip support.
      • Correct object drawing and attributes (e.g. zoom factors).
      • Road drawing.
      • Fix inter-CPU communications.
      • Layer mixing.
