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
This small patch makes some minor "code quality" improvements to MAME.
First off, some remaing static/const qualifier missed cases were
addressed. Secondly, a few cases of missing #include "foo.h" were
added. Thirdly, a few global names were modified to make them less
generic/more consistent (voodoo.c, vrender0.c, lethal.c, rungun.c,
zac2650.c). Fourthly, some dead/useless code was removed
(i8051.c,model1.c,romcmp.c).
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)
* 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.
* Marked invasn as playable.
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.
ADSP-2100:
* Properly documented ADSP-2104 internal memory map.
Removed many hacks from both.
A couple of games changed status from GAME_NOT_WORKING to fully playable:
stagger1, redhawk, redhawkb, grdnstrm, spec2k, firehawk (all - former afega.c)
and tharrier/tharrierj(nmk16.c)
invasn looks a lot better now.
Extracted data for lights.
Added backface culling which mostly works but fails sometimes, so it is disabled.
Started on some initial lighting calculations.
