This document describes the city data file format for SimCity. This
description is valid for the IBM, Macintosh and Amiga versions of
SimCity.

Total FinderInfo - This part of the file is only used by the Macintosh.
But the IBM and Amiga city files also create this in every file so cities 
can be moved to the Mac easily.

ResHis - This is the data seen in the Residential population line graph.
The first 120 integers represent the 10 year data (most recent first)
and the second 120 integers represent the 120 year data. The next 5
structures follow this format.

ComHis - The commercial population data.

IndHis - The industrial population data.

CrimeHis - The average crime level data. (scaled 0..255)

PolluteHis - The average pollution level data. (scaled 0..255)

CashFlowHis - The CashFlow data. (scaled 0..255, 128 is 0, <128 is negative 
CF, >128 is positive CF)

MiscVar - This is an array of integers used to store various things.
	MiscVar[1] - External Market Size.
	MiscVar[2] - Residential Population.
	MiscVar[3] - Commercial Population.
	MiscVar[4] - Industrial Population.
	MiscVar[5] - Residential Valve.
	MiscVar[6] - Commercial Valve.
	MiscVar[7] - Industrial Valve.
	MiscVar[8&9] - City Time. (current year = City Time/48 +1900)
	MiscVar[10] - CrimeRamp (used to smooth graphs)
	MiscVar[11] - PolluteRamp (used to smooth graphs)
	MiscVar[12] - LandValue Average.
	MiscVar[13] - Crime Average.
	MiscVar[14] - Pollution Average.
	MiscVar[15] - Game Level.
	MiscVar[16] - City Class. (village,town,city, etc)
	MiscVar[17] - City Score.
	MiscVar[50&51] - Total Funds (long value)
	MiscVar[52] - Flag for auto-bulldozer
	MiscVar[53] - Flag for auto-budget
	MiscVar[54] - Flag for auto-goto
	MiscVar[55] - Flag for sound On/Off
	MiscVar[56] - City Tax Rate
	MiscVar[57] - Simulation Speed
	MiscVar[58&59] - Police budget.
	MiscVar[60&61] - Fire budget.
	MiscVar[62&63] - Road budget.

Map - This is the city map. The map is 120 horiz. X 100 vert., each tile
represented by an integer. The lower 10 bits of the integer hold the index 
 for the tile, the upper 6 are "attributes" for that tile.

TILE ATTRIBUTES
	Bits[0-9] - Tile index #. (0-1023)
	Bit[10] - Is this a zone center tile?
	Bit[11] - Is this tile animated?
	Bit[12] - Is this tile bulldozable?
	Bit[13] - Can this tile burn?
	Bit[14] - Can this tile conduct power?
	Bit[15] - Is this tile currently powered?
