Fixed colours in Battle City [Roberto Gandola]

 

Slight change to the Arcadia Driver [Nathan Woods]

src/drivers/arcadia.c:

src/includes/amiga.h:

src/machine/amiga.c:

- Refactors 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

 

ST-V updates [Angelo Salese]

-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.

 

New Sound Functionality [Derrick Renaud]

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
