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

* [[Nicola Salmoria]] contributed a large Namco update:
** pacland: fixed sprite RAM, it was too big and included normal program RAM, causing sprites to be drawn twice.
** pacland: fixed irq enable
** pacland: fixed tilemap scroll offsets and sprite positions
** pacland: accurate emulation of tile/sprite priority (including fix of bugs introduced when the driver was converted to tilemaps) and sprite visibility area
** pacland36b16 is not a bug - colors match the real game
** added SOUND_NAMCO_CUS30 for better documentation (alias for the standard SOUND_NAMCO)
** drgnbstr36rc2gre
** skykidd works with a patch (a dump of the CUS60A internal ROM is needed to do without the patch)
** metrocross: fixed irq enable, this fixes inputs in service mode
** baraduke060gre
** baraduke36rc2gre, it is improved, there are still gaps left but this is correct behaviour verified on the real board
** baraduke, system86: understood how sprite RAM buffering works, this fixes sprite lag but causes a glitch in rthunder (which might be correct behaviour)
** system86: totally rewritten the 63701X emulation and moved it to a separate module. Fixed silence compression, this improves quality in some samples; supported volume control.
** genpeitd067gre fixed
** rthundro37b14red I think is fixed; but the game still sometimes crashes when you die
** rthunder, genpetid: fixed watchdog emulation, this allows entering service mode without resetting

* [[Angelo Salese]] made various ST-V Improvements (brightness controls)

* [[Pierpaolo Prazzoli]] committed Various Hyperstone core improvements

* [[Nathan Woods]] added misc fixes:
** Fixed the ABCD opcode for the hd6309
** Fixed a small typo in the DMADAC interface line in the sound system
** Added a security margin to the tms5220 in the estimate of the delay for speech synthesis ready line to come low (needed for a MESS side bug fix)
** Added some completion messages to chdman, and fixed the code that was falsely assuming that progress() was a function pointer
** Changed video_window_proc() to win_video_window_proc() and made non-static so that MESS's window proc can call it.
** Changed win_init_window() to use MESS's window proc (within #ifdef MESS of course)
** Added a win_suspend_directx global variable to temporarily turn off DirectX usage (used in MESS)
** Added a few minor MESS specific #ifdefs
** Added an entry for the TMS99100 processor
** Introduces cpu_getscanlinetime_mt() and cpu_getscanlineperiod_mt(); variants on their namesake calls except they return mame_time instead of double

* [[Oliver Achten]] improved the 053260 and NES APU emulation

* [[Aaron Giles]] made various improvements to the Gaelco3D system

* [[smf]] cleaned up the ZN driver

* [[Quench]] made misc 32010 related updates:
** TMS32010 CPU core
*** Added internal Data memory map
*** Fixed Overflow on the ADDH instruction
** Twin Cobra / Wardner
*** Converted to Tilemaps
*** Corrected Savestate setup
*** Little cleanups to the Machine code
*** Adjustments for TMS32010 internal data map
** Toaplan1
*** Corrected Savestate setup
*** Adjustments for TMS32010 internal data map
** HardDrivin
*** Adjustments for TMS32010 internal data map

* [[Alex Eddy]] fixed a vector clipping bug in mhavoc

* [[Lawrence Gold]] fixed some GCC warnings:
** ISO C89 forbids mixed declarations and code
** warning: comma at end of enumerator list

* [[Derrick Renaud]] updated the discrete sound support

* Discrete Sound Changes
** fixed/added more documentation of functions at top of discrete.h
** DISCRETE_555_ASTABLE - changed to use common options with DISCRETE_555_CC.
** DISCRETE_TRANSFORMx - fixed bug that preformed math in the wrong order.
** Also added more math functions.

* New Discrete Modules Added
** DISCRETE_555_CC - Constant Current based 555 VCO with 8 main configurations, that automatically configure from components used.
** DISCRETE_566 - NE566 simulation.
** DISCRETE_COMP_ADDER - Multiple parallel capacitor/resistor circuit.
** DISCRETE_DAC_R1 - R1 Ladder DAC that automatically configures from components used.
** DISCRETE_MIXERx - Resistor/Op Amp mixer stage with filtering that calulates proper gains & filtering. It automatically configure from components used.
** DISCRETE_SCHMITT_OSCILLATOR - VCO based on a Schmitt Inverter.

* Game Driver Changes
** poolshrk - Converted to new component value only code.
** firetrk, montecar, superbug - Converted to new component value only code. Pulled discrete code out and put in sndhrdw\ataridis.c. montecar still needs filtering on crash sound.
** atarifb, canyon & skydiver - minor changes to work with new code.
** triplhnt - added component value discrete sound, but have not figured out Shot and Bear Roar video memory locations. These are needed to make sound effects work.
