Spells not charging starts at offset 16 and contains 3 byres of data. These three bytes represent data for which spells are toggled as charging on the Spells Panel at the start of the game.  Any bit set to true will result in the corresponding spell being set to the "not charging" state at the beginning of the game, and any bit set to false will result in the corresponding spell being set to the "charging" state at the beginning of the game.  The user can change this state by right-clicking the icon of the spell.

==Fog of War and God Mode==


Fog of War and God Mode are stored in Byte 98.
==Bytes 0x14 - 0x33: Spells Available - Once==
 
The next 32 bytes represent the spells given once to the player at the start of the game.  They are indexed by spell model with each byte containing the number of that spell provided.
 
==Word 0x34: Vehicles Available==
 
These two bytes show the types of vehicles available to the player - if that was used.

Setting this byte to 1 will disable the training mana at the start of the level.
 
==Byte 0x37: Flags==
 
Unused.
 
==Bytes 0x38 - 0x57 Level Name==


===Byte 98===
The level name is 32 bytes (8 bit signed-characters) long.  This is only used for save games titles, not the level name that is  shown in level selection or the solar system view, that title is stored in the language file.


    00001101
==Byte 0x58: Number of Players==
          ||----[[Fog of War]]
          |-----[[God Mode]]


==Landscape and Tree Style==
Number of Players sets the number of tribes that will appear on the level. Colors go in the order (Blue, Red, Yellow, Green). In [[Single Player]] this must be set to the last color on the level or 03 for all of them. For example, for a map with only Blue and Yellow on the level, the number must still be set to 02. In [[Multiplayer]] this is how many players can play the level 02, 03, or 04.


The Landscape Style is 1 byte starting at byte 96 and the Tree Style is 1 byte starting at byte 97.
==Bytes 0x59 - 0x5B Computer Player Index==


===Byte 96===
Each byte is the script number for a color (Red, Yellow, Green).  Note that while the files are in decimal, that must be converted into hex when stored in the header file (Cpscr010.dat = 010 = 0A).


There are 36 landscape styles. In hex that is from 00 to 24.
==Bytes 0x5C - 0x5F Allies==


===Byte 97===
[[Single Player]] only.
There is one byte for each type containing the tribes it is allied with.  The first four bits of the byte represent the four tribes, with a set bit meaning that tribe is an ally.  A tribe must always ally itself, and the alliance is one way - e.g. Blue could be set to be allied to green, but green must also have the same value in the byte to be allied to blue.


There are 5 tree styles. In hex, they are 00, 03, 04, 05, 06.
Example: Blue is allied with green (byte 0x5C).
    00001001
        ||||----Blue
        |||-----Red
        ||------Yellow
        |-------Green

Example: Red is allied with Yellow (byte 0x5D).
    00000110
        ||||----Blue
        |||-----Red
        ||------Yellow
        |-------Green


Maximum Tribes sets the number of enemy tribes that will appear on the level. In [[Single Player]] you must set this to the last colour on your level or 03 for all of them. Colours go in the order (Blue, Red, Yellow, Green). If you wanted to have only Blue and Yellow on a level, then the number must still be set to 02. In [[Multiplayer]] you just set this to how many players the level has minus one as you cannot omit colours. It is 1 byte long and starts at byte 88.
==Byte 0x60: Level Type - Color Scheme==


===Byte 89===
There are 36 landscape styles. In hex that is from 0x00 to 0x23.


01 - Blue
==Byte 0x61: Object Bank - Tree Styles==
02 - Blue & Red
03 - Blue, Red & Yellow
04 - Blue, Red, Yellow & Green


==AI Scripts==
There are 8 tree styles. In hex, they are 0x00 to 0x07.


AI Scripts are 3 bytes long and starts at byte 89. Each byte is for each colour (Red, Yellow, Green). You must type the script number in hex for it to link to that script. (Cpscr010.dat = 010 = 0A)
==Byte 0x62: Level Flags==


==Allies==
These properties can be used in the [[Single Player]] mode only.
If the bit is on the property is available. In this example Fog of War, God Mode and Forge World are available:

==Byte 0x63: Bonus!==
Red = 02
Yellow = 04
Green = 08


An ally equals the two colours together. To make yellow and blue allies you would add Blue(01) and Yellow(04) together which makes 05. Then put 05 for yellow and blue (05 02 05 08).
Padding byte.


==Level Name==
==Words 0x64 - 0x262: Markers==
Markers are pairs of X-Y bytes identifying the x/y coordinates of the marker.  There are 100 available markers.


The level name starts at offset 55 (37 in hex) and is 30 bytes (characters) long.
==Word 0x264: Camera Start Position==


==Markers==
[[Single Player]] only.
The square to look at when the level starts.  The bytes are in X, Y format.  0,0 implies start at the shaman.


Markers are the 256*2 offsets, starting at offset 100 (in decimal).
==Word 0x266: Camera Start Angle==
Offset 100 being the x coordinate of marker 0, and Offset 101 being the y coordinate of marker 0.


This goes in a pattern until all 256 (0 to 255) markers are used up.
[[Single Player]] only.
The angle to look at when the level starts.

The Header (.hdr) is a Populous Level File which contains the level's attributes.

Long 0x08: Buildings Available - Level

The third long represents the buildings available for the level in the same sense as given from a worship item. These are organized the same way as the buildings available.
