Mame 0.122u1 update

[Robert]

Source

As a little pre-Christmas treat, we have the first update to MAME 0.122 posted at the Source Updates page. The big news here is a working driver for the upright Buggy Boy, thanks to Philip Bennett. Haze and Dox have been busy cleaning up the afega and nmk16 drivers, and as a result a large number of previously non-working games are now working. In addition to the Buggy Boy work, Philip also submitted a nice fix to the Namco NA1 sound which improves the results substantially.

 

Happy holidays!

Source Changes

------------------------

Zeus updates: [Aaron Giles]

* 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.

 

Afega/nmk16 cleanups: [David Haywood, Tomasz Slanina]

* Merged afega.c and nmk16.c drivers

* Removed many hacks from both.

* Fixed a number of games

 

Fixed C219 sample read order and implemented sign+magnitude format. Removed GAME_IMPERFECT_SOUND flag from all Namco NA-1 games. [Philip Bennett]

 

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 bug that would cause events to leak through to the game when the debugger was up. [Aaron Giles]

 

Verified some cpu clocks of original boards using a frequency counter: [Corrado Tomaselli]

* 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)

 

Minor "code quality" improvements: [Atari Ace]

* 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)
