It draws a series of small tiles ("chunks") together to

the spritemap rom, creating each 64x64 sprite as follows:
0 1 2 3

8 9 10 11
12 13 14 15
16 17 18 19
20 21 22 23

28 29 30 31
The game makes heavy use of sprite zooming.

NB: unused portions of the spritemap rom contain hex FF's.
It is a useful coding check to warn in the log if these
are being accessed. [They can be inadvertently while
spriteram is being tested, take no notice of that.]

VDP CTRL Reads / Writes (Accesses to 0xC00004 - 0xC00007)
*******************************************************************************
A Read from the Control Port will return the Status Register Value.
16-bits are used to report the VDP status
| 0 | 0 | 1 | 1 | 0 | 1 | FIFE | FIFF |
| VIP | SOF | SCL | ODD | VBLK | HBLK | DMA | PAL |
0,1 = Set Values
FIFE = FIFO Empty
FIFF = FIFO Full
VIP = Vertical Interrupt Pending
SOF = Sprite Overflow (Not used in C2 afaik)
SCL = Sprite Collision (Not used in C2 afaik)
ODD = Odd Frame (Interlace Mode) (Not used in C2 afaik)
VBLK = In Vertical Blank
HBLK = In Horizontal Blank
DMA = DMA In Progress
PAL = Pal Mode Flag
Control Writes are used for setting VDP Registers, setting up DMA Transfers
etc.
A Write to the Control port can consist of 2 16-bit Words.
When the VDP _isn't_ expecting the 2nd part of a command the highest 2 bits
of the data written will determine what it is we want to do.
10xxxxxx xxxxxxxx will cause a register to be set
anything else will trigger the 1st half of a 2 Part Mode Setting Command
If the VDP is already expecting the 2nd half of a command the data written
will be the 2nd half of the Mode setup.

Convert the color PROMs.
Pacland has one 1024x8 and one 1024x4 palette PROM; and three 1024x8 lookup
table PROMs (sprites, bg tiles, fg tiles).
The palette has 1024 colors, but it is bank switched (4 banks) and only 256
colors are visible at a time. So, instead of creating a static palette, we
modify it when the bank switching takes place.
The color PROMs are connected to the RGB output this way:
bit 7 -- 220 ohm resistor -- GREEN
-- 470 ohm resistor -- GREEN
-- 1 kohm resistor -- GREEN
-- 2.2kohm resistor -- GREEN
-- 220 ohm resistor -- RED
-- 470 ohm resistor -- RED
-- 1 kohm resistor -- RED
bit 0 -- 2.2kohm resistor -- RED
bit 3 -- 220 ohm resistor -- BLUE
-- 470 ohm resistor -- BLUE
-- 1 kohm resistor -- BLUE
bit 0 -- 2.2kohm resistor -- BLUE
