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 recorded.
  • robotbwl - added discrete simulation for footsteps
  • crash - added discrete simulation for beeper

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.

  • 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 scrolls
  • - Fixed VSync
  • Fixed dips in Sky Lancer
  • playmark.c update

  • Added Continue dipswtich in Big Twin

Other Changes

Buggy Boy/Speed Buggy
