Specific Contributions

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

• Aaron Giles changed how perodic timers are defined. Previously, you would specify a number which was interpreted either as Hz (if less than 50000) or as nanoseconds (if greater than 50000). Now, the time is specified as a period and you use the standard TIME_IN_HZ or TIME_IN_NS macros.

• Aaron Giles turned on address error checking in the 68000 core. This slows things down a bit but is more accurate and allows correct behavior of a couple of badly-programmed games.

• Aaron Giles fixed several issues with address error checking in the 68000 core.

• Aaron Giles fixed a 68000 bug that treated 8-bit branches with $FF offsets as illegal, rather than allowing them and generating an address error.

• Aaron Giles created a new header file mamecore.h, which contains the core common useful macros and typedefs that were scattered throughout the header files. Also added endian swapping macros from MESS.

• Aaron Giles fully deprecated the use of cpu_setbank(), which was long ago replaced with memory_set_bankptr().

• Aaron Giles did some major cleanup on the MCR drivers:
  • Implemented Super Sound I/O interrupts properly.
  • Filled out all memory maps according to schematics.
  • Fixed sound sync with various sound boards, allowing for kludges to be removed from Power Drive and Star Guards.
  • Re-verified all connections from wiring diagrams.
  • Documented various lamp and driver boards from the games.

• Atari Ace made some makefile tweaks to hopefully catch variable declaration problems that kept creeping into builds. Switched gcc compiler standard to gnu89.

• Atari Ace removed the usage of dirent.h APIs on Windows builds.

• Mamesick corrected the resolution to 256x256 in Stagger I, Red Hawk, Sen Jin - Guardian Storm. All other games still have old visible area that is correct for them.

• Nicola Salmoria fixed a crash in Volfied and Operation Wolf due to improper timer usage.

• Bryan McPhail fixed one of the TC360 sprite blending modes (used in Pulirula round 2 and Liquids Kids attract mode).

• Phil Stroffolino fixed sprite/tilemap placement in Legend of Kage.

• Nathan Woods updated the PowerPC core:
  • Added infrastructure to generate DSI and ISI exceptions
  • Made the lbz/lbzu/lbzux/lbzx instructions properly clear out the high 24 bits in the results
  • Added SRR0 and SRR1 to the debug view

• Pierpaolo Prazzoli did some cleanups in the vamphalf.c driver.

• Pierpaolo Prazzoli fixed speedbal again, after breaking it in the last update.

• Pierpaolo Prazzoli changed Nitro Ball to use the new deco16_tilemap_34_combine_draw function Bryan added some time ago.

• Pierpaolo Prazzoli added a sprite wrap around needed in Riot level 2.

• Pierpaolo Prazzoli added sound to Dragon Bowl.
