== 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)
