Specific Contributions

The known contributions for this version are, in the order specified in the whatsnew:

  • Aaron Giles contributed Zeus updates:
    • Figured out data format of 2 matrix form.
    • Extracted data for lights.
    • Added backface culling which mostly works but fails sometimes, so it is disabled.
    • Started on some initial lighting calculations.
    • Cleaned up zeus wave RAM accessors.
    • Changed rendering code to allow for greater parallelism on multicore systems.
    • Removed some vestigial zeus 2 hacks.
    • Reduced visible area to remove artifacts.
    • Made right/bottom vertices inclusive to fix some gapping issues.
    • Fixed invasn lightgun offset.
    • Zeus 2 hardware:
      • Fixed ROM loading, added banking support.
      • Separated zeus 2 video implementation from zeus implementation.
      • Implemented direct pixel accesses; enough to get startup screens to show.
      • Hooked up ZPRAM.
      • Fixed digital inputs for crusnexo.
      • Fixed default screen parameters to match the games.
  • David Haywood and Tomasz Slanina made Afega/nmk16 cleanups:
    • Merged afega.c and nmk16.c drivers
    • Removed many hacks from both.
    • Fixed a number of games
  • Philip Bennett fixed the C219 sample read order and implemented sign+magnitude format. Removed GAME_IMPERFECT_SOUND flag from all Namco NA-1 games.
  • Aaron Giles fixed ROM-based DCS2 system to ignore HLE transfers. (Fixes broken sound in invasn.) Properly reduced internal memory on the ADSP-2104 variants.
  • Aaron Giles fixed a bug that would cause events to leak through to the game when the debugger was up.
  • Corrado Tomaselli verified some cpu clocks of original boards using a frequency counter:
    • Changed Success Joe Ym2203 clock from 3mhz to 4mhz
    • Changed Pang M6295 clock from 990khz to 1Mhz
    • Changed Halley Comet main cpu clock to 1.664mhz (it's not a mistake, the clock is very low)
    • Besides confirming clocks on some games, I modified:
    • Aerofighters and Turbo Force sound z80 to 5mhz
    • Midnight Resitance 68k cpu to 10mhz (20mhz crystal) and modified m6295 clock to 1mhz. Also confirmed pin 7 is high. (Midnight resistance has a lot of slow downs on the pcb too)
  • Atari Ace made minor "code quality" improvements:
    • fixed some remaining static/const qualifier missed cases
    • fixed some missing #include "foo.h"
    • a few global names were modified to make them less generic/more consistent (voodoo.c, vrender0.c, lethal.c, rungun.c, zac2650.c)
    • some dead/useless code was removed (i8051.c,model1.c,romcmp.c)
