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

* [[Vas Crabb]] made some minor changes in the inline code. The result of atomic_add32 isn't used a lot of the time, so the final addition was brought out to allow it to be optimized away. Removed the unnecessary delta argument from atomic_increment32 and atomic_decrement32 in eminline.h, and added implementations. Changed the condition for using rgbsse.h to include 32-bit platforms with SSE enabled.

* [[Vas Crabb]] did a major clean-up of the input ports in ssv.c. Brought out the common joystick, mahjong and quiz input setups, and then used PORT_INCLUDE to pull them in when needed. Also brought out the common coinage settings, to avoid needless repetition.

* [[Atari Ace]] analyzed all driver interfaces (DRIVER_INIT, READ8_HANDLER, etc.) to determine which ones should be made static and properly tagged them all to reduce global namespace pollution. Some cases turned out to be dead code, which was also properly tagged.

* [[Jarek Burczynski]] updated the Tube Panic driver, fixing the background scroll-in (it's smooth again now). The problem was caused by wrong synchronization between main and slave CPUs. Also modified the video driver to be scanline accurate and implemented more accurate interrupt handling.

* [[couriersud]] altered TTL low high levels in res_net.c. This will broaden the color range a bit. Since the results are normalized, there is only a limited effect visible.

* [[Sonikos]] cleaned up inputs and added dip locations in ms32.c. Also fixed dips in "47pie2" and "akiss".

* [[Nathan Woods]] fixed a bug that caused incorrect input to be read if multiple inputs were mapped to the same mouse input under Windows.

* [[Jim Stolis]] fixed a bug in the i8051 core that improperly fired the Timer2 interrupt when it wasn't enabled.

* [[Jim Stolis]] made updates to the peplus driver:
** Added lightpen support
** Added PE+ Superboard support
** Added ABC coin optics support
** Added full I2C eeprom support
** Added NVRAM support
** Corrected door closure issues
** Removed most memory hacks
** Consolidated machines and inputs
** New layout for pepp0158

* [[James Wallace]] split up the MPU4 driver into a core and driver set up a la NeoGeo. Also made some timer fixes, and added some new ROMs added.

* [[Chris Hardy]] fixed problems introduced when the junofrst blitter code was simplified.

* [[Roberto Fresca]] contributed a major American Poker II rewrite:
** Properly dervied clocks from crystals
** Reworked TILE_GET_INFO to handle the proper tiles/color codes.
** Fixed interrupts (NMI).
** Corrected AY8910 frequency to 1.5 MHz to match the real thing.
** Arranged the AY8910 volume in all games avoiding clips.
** Corrected the screen visible area.
** Added NVRAM support.
** Reworked the memory map, mapping all the hardware I/O ports.
** Reworked the Inputs for all sets.
** Added implementation of Operator and Supervisor Keys.
** Fixed some timing troubles.
** Added partial DIP switch support with diplocations to all sets.
** Removed the hack in DRIVER_INIT.
** Hooked write handlers for output ports.
** Added watchdog routines.
** Dumped, hooked, wired and decoded the color PROM in all sets.
** Modified the refresh rate according to hardware measurements.
** Wired the lamps for all sets. Created their respective layouts.
** Splitted the driver to driver/video.
** Other minor fixes.

* [[kingshriek]] added SCSP fixes:
** Fixed DECAY1 envelope state to not exit immediately
** Improved support for LPSLNK and SBCTL
** Fixed panning calculation bug
** Fixed case where key-rate scaling is off

* [[Vas Crabb]] added support for indicating that DIP switches are reversed in the DIP locations view.

* [[Vas Crabb]] added DIP locations for Midway Tron and the Nintendo Donkey Kong series (dkong.c).

* [[Vas Crabb]] added an Altivec/VMX implementation of the RGB utilities for our friends with G4, G5 and POWER5 CPUs (rgbvmx.h) and added rgbint_bilinear_filter and rgbaint_bilinear_filter to rgbsse.h (based on rgb_bilinear_filter/rgba_bilinear_filter) for completeness, as these functions exist in rgbgen.h.

* [[Aaron Giles]] updated model2.c, taitojc.c, and gticlub.c to use the new polygon routines. Deprecated the old poly.c and renamed polynew.* to poly.*.

* [[Aaron Giles]] unified poly.c callbacks so that tri and quad callbacks work the same way.

* [[Aaron Giles]] fixed display of floating point TMS32031 registers in the debugger.

* [[Aaron Giles]] fixed TMS32031 ABSF opcode to work as documented and not produce a proper negative.
