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.
