All games contain three BAC06 background generator chips, usual (software)
configuration is 2 chips of 16*16 tiles, 1 of 8*8.
Playfield control registers:
bank 0:
0:
bit 0 (0x1) set = 8*8 tiles, else 16*16 tiles
Bit 1 (0x2) unknown
bit 2 (0x4) set enables rowscroll
bit 3 (0x8) set enables colscroll
bit 7 (0x80) set in playfield 1 is reverse screen (set via dip-switch)
bit 7 (0x80) in other playfields unknown
2: unknown (00 in bg, 03 in fg+text - maybe controls pf transparency?)
4: unknown (always 00) [Used to access 2nd bank of tiles in Stadium Hero)
6: playfield shape: 00 = 4x1, 01 = 2x2, 02 = 1x4 (low 4 bits only)
bank 1:
0: horizontal scroll
2: vertical scroll
4: colscroll shifter (low 4 bits, top 4 bits do nothing)
6: rowscroll shifter (low 4 bits, top 4 bits do nothing)
Row & column scroll can be applied simultaneously or by themselves.
The shift register controls the granularity of the scroll offsets
(more details given later).
Playfield priority (Bad Dudes, etc):
In the bottommost playfield, pens 8-15 can have priority over the next playfield.
In that next playfield, pens 8-15 can have priority over sprites.
Bit 0: Playfield inversion
Bit 1: Enable playfield mixing (for palettes 8-15 only)
Bit 2: Enable playfield/sprite mixing (for palettes 8-15 only)
Priority word (Midres):
Bit 0 set = Playfield 3 drawn over Playfield 2
~ = Playfield 2 drawn over Playfield 3
Bit 1 set = Sprites are drawn inbetween playfields
~ = Sprites are on top of playfields
Bit 2
Bit 3 set = ...

playfield (ie, 256*1024, 512*512 or 1024*256). So even if the tilemap
width is only 256, 'src_x' should not wrap at 256 in the code below (to
do so would mean the top half of row RAM would never be accessed which
is incorrect).
Nb2: Real hardware exhibits a strange bug with column scroll on 'mode 2'
(256*1024) - the first column has a strange additional offset, but
curiously the first 'wrap' (at scroll offset 256) does not have this offset,
it is displayed as expected. The bug is confimed to only affect this mode,
the other two modes work as expected. This bug is not emulated, as it
doesn't affect any games.

/*
Deco BAC06 tilemap generator:
this a direct relative of the later chip implemented in deco16ic.c
we could implement this as either an 8-bit or a 16-bit chip, for now
I'm using the 16-bit implementation from dec0.c
Notes (from dec0.c)
All games contain three BAC06 background generator chips, usual (software)
configuration is 2 chips of 16*16 tiles, 1 of 8*8.
Playfield control registers:
bank 0:
0:
bit 0 (0x1) set = 8*8 tiles, else 16*16 tiles
Bit 1 (0x2) unknown
bit 2 (0x4) set enables rowscroll
bit 3 (0x8) set enables colscroll
bit 7 (0x80) set in playfield 1 is reverse screen (set via dip-switch)
bit 7 (0x80) in other playfields unknown
2: unknown (00 in bg, 03 in fg+text - maybe controls pf transparency?)
4: unknown (always 00) [Used to access 2nd bank of tiles in Stadium Hero)
6: playfield shape: 00 = 4x1, 01 = 2x2, 02 = 1x4 (low 4 bits only)
bank 1:
0: horizontal scroll
2: vertical scroll
4: colscroll shifter (low 4 bits, top 4 bits do nothing)
6: rowscroll shifter (low 4 bits, top 4 bits do nothing)
Row & column scroll can be applied simultaneously or by themselves.
The shift register controls the granularity of the scroll offsets
(more details given later).
Playfield priority (Bad Dudes, etc):
In the bottommost playfield, pens 8-15 can have priority over the next playfield.
In that next playfield, pens 8-15 can have priority over sprites.
Bit 0: Playfield inversion
Bit 1: Enable playfield mixing (for palettes 8-15 only)
Bit 2: Enable playfield/sprite mixing (for palettes 8-15 only)
Priority word (Midres):
Bit 0 set = Playfield 3 drawn over Playfield 2
~ = Playfield 2 drawn over Playfield 3
Bit 1 set = Sprites are drawn inbetween playfields
~ = Sprites are on top of playfields
Bit 2
Bit 3 set = ...

shift registers for each which control the granularity of the row/col

Nb: The row & col selectors are _not_ affected by the shape of the
playfield (ie, 256*1024, 512*512 or 1024*256). So even if the tilemap
width is only 256, 'src_x' should not wrap at 256 in the code below (to
do so would mean the top half of row RAM would never be accessed which
is incorrect).
Nb2: Real hardware exhibits a strange bug with column scroll on 'mode 2'
(256*1024) - the first column has a strange additional offset, but
curiously the first 'wrap' (at scroll offset 256) does not have this offset,
it is displayed as expected. The bug is confimed to only affect this mode,
the other two modes work as expected. This bug is not emulated, as it
doesn't affect any games.
