- 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
-
- used by:
-
- actfancr.c
- dec0.c
- dec8.c (oscar, cobracom, ghostb)
- madmotor.c
- stadhero.c
- pcktgal.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) set = row major tile layout, else column major*
- 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).
-
- * Bandit is the only game known to use column major tile layout, when in this
- mode X scrolling is also inverted, and tile character data is flipped on X.
-
-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 = ...
-
- Note that priority mixing is handled outside of the BAC-06 chip.

- 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
