The known contributions for this version are, in the order specified in the whatsnew:
- Aaron Giles added a new 'screen' parameter to the VIDEO_UPDATE callbacks. It is not currently used but is a placeholder for the future.
- Aaron Giles replaced direct access to Machine->scrbitmap in the following drivers with the use of force_partial_update(): m92.c, m107.c, astrocde.c, battlera.c, snes.c.
- Aaron Giles rewrote the Z80/Z180 daisy chaining logic to work a little closer to the hardware. Updated the Z80 CTC and PIO modules to support the new model. Changed the CTC module to not generate interrupts if there is an outstanding request on the same timer is currently in service; this allows Journey to (finally) run with the correct CPU speed.
- Aaron Giles did a partial rewrite of the MCR video system. Should still work roughly the same, just a little different under the covers. This is still very much a work in progress.
- Fujix fixed clipping in nemesis.c.
- Mamesick normalized names in Konami drivers according R. Belmont's wishes.
- Nathan Woods committed more PowerPC updates:
- Moved update_counters() to be executed after the DRC epilogue code is appended; now behaves more like the non-DRC core
- Fixed some bugs in DRC exeception handling (SRR1 was not being set up properly, and not all MSR flags were being cleared)
- Refactored DRC core to call MMU hooks
- ISI exceptions will now be thrown if the MMU hooks report an unexecutable address in the DRC core
- Fixed a rounding error in the decrementer
- Added support for decrementer exceptions when the DEC register is written to in both cores
- Added support for ISI/DSI exceptions with setjmp()/longjmp() in the non-DRC core
- Phil Stroffolino did a significant rewrite of the Legend of Kage driver:
- correct/added dipswitches
- converted to use pdrawgfx; affects stage#4
- a priority effect on the title screen has been mapped - this gives the foreground layer priority over all sprites, and screenshots now match those from arcade flyers.
- the "virtual palette" hack has been removed; it was an optimization from back when we used 8 bit color and hardware palettes.
- Pierpaolo Prazzoli cleaned up the Soungoku Mahjong driver, fixed colors, improved sound and fixed the hang before the match started. Also I found the output for the coins used to play the match. It's still missing something to enable / disable the tilemaps.
- Ville Linde and * David Haywood fixed the i386->z80 communication in the Seibu SPI driver. This fixes the flash rom update and should also fix any remaining hangs/pauses. The flash rom update should take around 5 minutes. Now all names should have proper sample data.
