General Source Changes
----------------------
Big 80s Namco Update [Nicola Salmoria]
this affects the first Namco games that used custom I/O chips.
- these files are no longer needed and should be removed: drivers/bosco.c,
  drivers/xevious.c, drivers/digdug.c, machine/digdug.c, machine/galaga.c,
  machine/bosco.c, machine/polepos.c, sndhrdw/bosco.c
- added three new sound chips: NAMCO_15XX, NAMCO_52XX, NAMCO_54XX, and
  changed drivers to use them (NAMCO_54XX is just a placeholder playing
  samples, until the chip is reverse engineered).
- MAME testers bugs fixed: digdug063gre, galaga057gre, bosco071u2gre,
  poleposc059gra
- added EAROM support to digdug
- fixed the polepos2 title screen which had been broken since day 1, strange
  that nobody noticed.
- fixed various mistakes in the polepos ROM loading (one missing speech ROM
  in polepos,  polepos2 was using the wrong engine sound ROMs (it's turbo!),
  added missing vertical scaling PROMs).
- extensive documentation of ROM names and placement, and differences
  between Namco and licensed versions.
- converted all drivers to tilemaps, and made gfx emulation more accurate
  according to schematics
- polepos sprite zooming should now be closer to the hardware.
- IP_KEY_PREVIOUS and IP_JOY_PREVIOUS are no longer used by any driver: they
  may be removed from the core.
- support for start lamps, coin counters and coin lockout (all
  internallyhandled by the custom I/O chip)
- toggling the test switch while the game is running enters test mode
  without need to manually reset.
- found and documented test mode Easter eggs in all games except Xevious.
- bosconian now uses a different sound PROM, which seems more correct.
- galaga uses better dumps of the PROMs, with the unused top 4 bits set to
  0.
- correct handling of 52XX sample start/end pointers in ROM.
- better emulation of 50XX custom, no more need for hacks in bosconian.
- swapped digdug and digdugb, the main set should be the newer one.
- removed these galaga clones: nebulbee (copyright/name change), galagab2
  (mix 'n match of ROMs from other sets), galaga84 (copyright/gfx change),
  galagads (1-byte hack to get fast shoot,
  reproducible with this line in cheat.dat:
  galaga:1:070D:0D:100:Fast Shoot)
- added Galaga rev. B, which is now the main set, renamed the other galagao.
- added galagamk, a different Midway version.
- removed various bad dumps from polepos2b and poleps2c, they turned out to
  be the same version so poleps2c is removed.
- drivers/locomotn.c is no longer needed and should be removed
- converted to tilemaps, consolidated as much as I could
- fixed: jungler37b3gre
- correct tile/sprite priority handling (also in Bosconian)
- documented the Easter egg in Rally X
- added starfield in Tactician
- fixed the RC filter control in the games with Konami sound
Big Namco NB1 update [Phil Stroffolino]
Various improvements for System NB emulation, including:
- new driver: Greatest Slugger '93 (Japan)
- hardware shadow support (used heavily in Greatest Slugger)
- dedicated random number generator chip
- sprite stretch glitch (affects Outfoxies intro)
- tilemap tile banking feature (used by Mach Breakers)
- removed several game-specific hacks; now uses dedicated CPU registers
  for interrupts
- preliminary support for screen blanking (hides garbage in Outfoxies)
- proper POSIRQ handling, for scanline effects.  Fixes the water
  effects in Outfoxies.  This same feature needs to be folded into System
  2 emulation, but I haven't gotten around to it yet.
- various Mach Breaker-specific hacks for interpretting the ROZ layer
  registers; these aren't yet fully understood.  In particular, the
  "Monster Pull" stage is missing a "3d floor."
