Specific Contributions

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

• Roberto Gandola Fixed colours in Battle City

• Nathan Woods slightly changed the Arcadia Driver: Refactored code specific to the Arcadia arcade system and the Amiga computer out of src/machine/amiga.c into callbacks. This allowed me to get rid of all #ifdef MESS code out of src/machine/amiga.c

• Angelo Salese committed ST-V updates:
  • Fixed a bug with the VDP-1 ram reading, SH-2 can do byte or word access, it's implicit that can't do long word access. This fixes the Steep Slope Sliders booting so the game now works.
  • VDP-1 PTM's "draw by request" was actually causing sprites to flicker in kiwames,reversed back to old implementation until I or somebody else understand what the current issue is (clear_framebuffer?)
  • Finished the game header update,let me know if you like/don't like the system used for the description of the games.
  • fixed a ST-V visible area incorrectness which was causing Virtual Mahjong 2 to crash after the sound ram check
  • fixed a window effect bug in Double-density interlace mode,this fixes some graphics in vmahjong & myfairld.
  • Guessed a bitmap positioning issue in double-density interlace mode,this fixes the NBG1 positioning in myfairld.
  • My Fair Lady now works but only with sound disabled.I have not removed the NOT_WORKING status due to that.

• Derrick Renaud added new sound functionality
  • Took Frank Palazzolo's DISCRETE_FILTER2 code and made it work outside of the discrete system. See sound\filter.h for new functions.
  • Added op-amp bandpass filtering circuit to sound\namco54.c
  • Game Driver Changes
    • bosco, galaga, polepos, xevious - added proper filters to new Namco54 noise source.

• Nicola Salmoria fixed a Priority bug in Kid Niki and fixed crash on last level

• Pierpaolo Prazzoli fixed priorities in Lot Lot

• Nicola Salmoria decrypted Sukeban Jansi Ryuko

• Steve Ellenoff added a ARM7 CPU core

• Nathan Woods patched the G65816 CPU core: Cleaned up the code a bit; make some functions static and added step over/out support to the disassembler.

• Hans de Goede fixed a 6809dasm.c compiler warning

• Ville Linde updated the Model 3 driver:
  • PowerPC core:
    • Better interrupt handling. Nested interrupts work properly.
    • Some support for PPC602
    • Major bugfixes
    • Added some unimplemented opcodes
  • 53c810 SCSI:
    • Fixed single-stepping mode DMA
    • Added memory moves and DMA callback
  • Model 3:
    • Added Epson RTC-72421 emulation

    • Preliminary (not working yet) sound emulation
    • Too much to list :) Most Step 1.x games show
    • something now, up to and including full 3D.
