Custom chip 59 = 68000 cpu
Custom chip 101 = Arm6 cpu
Custom chip 113 = Alpha blending
Custom chip 153 = Alpha blending (same functions as 113, smaller PQFP package)
Custom chip 99 = 'Ace' chip (Alpha blending with palette effects)
Custom chip 156 = Encrypted ARM cpu
Custom chip 102 = Encrypted 68000 cpu
Custom chip 55 provides two playfields of 4bpp tiles, with optional
rowscroll and column scroll. Some games use two of these to give
4 playfields. Palette banking, tile banking and priority are outside
the scope of this chip, and usually differ between games. Some games
combine the 4bpp output of each playfield to give an effective 8bpp
display.
Custom chip 56 is the same as 55 but with on-chip decryption, so
encrypted roms can be used.
Custom chip 74 is the same as 56 but with different decryption tables.
Custom chip 141 is same as 56, but can output up to 8BPP per layer.
Custom chip 55/56/74/141 control register layout:
Word 0:
Mask 0x0080: Flip screen
Mask 0x007f: ? Possibly a bit to set transparent pen 0 on/off
Word 2:
Mask 0xffff: Playfield 2 X scroll
Word 4:
Mask 0xffff: Playfield 2 Y scroll
Word 6:
Mask 0xffff: Playfield 1 X scroll
Word 8:
Mask 0xffff: Playfield 1 Y scroll
Word 0xa:
Mask 0x8000: Playfield 1 enable
Mask 0x7800: Playfield 1 rowscroll style
Mask 0x0700: Playfield 1 colscroll style
Mask 0x0080: Playfield 2 enable
Mask 0x0078: Playfield 2 rowscroll style
Mask 0x0007: Playfield 2 colscroll style
Word 0xc:
Mask 0x8000: Playfield 1 is 8*8 tiles else 16*16
Mask 0x4000: Playfield 1 rowscroll enabled
Mask 0x2000: Playfield 1 colscroll enabled
Mask 0x1800: Seemingly unused
Mask 0x0400: Use alternate palette bank (unimplemented/unused by any game)
Mask 0x0200: Y flip tiles with top bit of palette code set (palette becomes 3 bits for this tile)
Mask 0x0100: X flip tiles with top bit of palette code set (palette becomes 3 bits for this tile)
Mask 0x0080: Playfield 2 is 8*8 tiles else 16*16
Mask 0x0040: Playfield 2 rowscroll enabled
Mask 0x0020: Playfield 2 colscroll enabled
Mask 0x0018: Seemingly unused
Mask 0x0004: Use alternate palette bank (unimplemented/unused by any game)
Mask 0x0002: Y flip tiles with top bit of palette code set (palette becomes 3 bits for this tile)
Mask 0x0001: X flip tiles with top bit of palette code set (palette becomes 3 bits for this tile)
Word 0xe:
Mask 0xff00: Playfield 1 gfx rom banking (Usually different hookup per game)
Mask 0x00ff: Playfield 2 gfx rom banking
Colscroll style:
0 8 pixel columns across bitmap
1 16 pixel columns across bitmap
2 32
3 64
4 128
5 256
6 512
7 1024 (Effectively 0 as 1024 is the width of the bitmap)
Rowscroll style:
0 512 rows down bitmap in 16x16 tile mode, 256 rows in 8x8 mode
1 256 rows in 16x16, 128 in 8x8
2 128 / 64
3 64 / 32
4 32 / 16
5 16 / 8
6 8 / 4
7 4 / 2
8 2 / 1
9-15 Untested on hardware, no known games set this anyway. Assumed invalid (no rowscroll)
Column and rowscroll can both be applied at once.
2010-02: Converted to be a device.
TODO:
- convert to c++ device
- should the decryption functions for the tilemap chips be here too?
it seems overall height / width of the tilemaps can be configured somehow
darkseal clearly needs 64 rows, whereas other games need 32.
width seems configurable in a similar way, with nitroball and lockload
needing narrower tilemaps. lockload/dragngun might be a good study case
as they run on the same harwdare, and both rely on different behavior.
