'''BASE.DAT:''' Each entry is 292 Bytes long

'''00-0E:''' Base Name, pretty obvious

'''0F:''' Presumably the Null character if the Base Name uses all 15 characters

'''10:''' Base's short range detection capability.

'''12:''' Base's long range detection capability.

'''14:''' Base's hyperwave detection capability.

'''11, 13, 15:''' These are probably the high bytes for the Short, Long, and Hyper-wave detections respectively. Should always be 0 as a value of 100 (hex: 64 00) is perfect detection.

Logical values for the detection capabilities:

''10 short, 0 long:'' This base has small radar(s) only.

''20 short, 20 long:'' This base has large radar(s) only.

''30 short, 20 long:'' This base has small and large radar(s).

''100 hyperwave:'' This base has a hyperwave decoder(s).

The radar values can be set to 100 for perfect short range detection (presumably -- it definitely makes UFOs appear more often), but these reset to the correct values any time you complete a build in that base.

'''16-39:''' The next offsets are arranged so they're easier to understand. They are for facilities in the base:

{| {{stdTable}} border="1" cellpadding="5" style="border: 0px solid; text-align: center"
|-
| 16 || 17 || 18 || 19 || 1A || 1B
|-
| 1C || 1D || 1E || 1F || 20 || 21

|-
| 2E || 2F || 30 || 31 || 32 || 33
|-
| 34 || 35 || 36 || 37 || 38 || 39
|}

The possible values are as follows:
00 - Access Lift
01 - Living Quarters
02 - Laboratory
03 - Workshop
04 - Small Radar System
05 - Large Radar System
06 - Missile Defense
07 - General Stores
08 - Alien Containment
09 - Laser Defense
0A - Plasma Defense
0B - Fusion Ball Defense
0C - Grav Shield
0D - Mind Shield
0E - Psionic Laboratory
0F - Hyper-wave Decoder
10 - Hangar (Top Left)
11 - Hangar (Top Right)
12 - Hangar (Bottom Left)
13 - Hangar (Bottom Right)
FF - Empty

'''3A-5D:''' The next offsets represent the days until a facility is completed. They're set up the same way:

{| {{stdTable}} border="1" cellpadding="5" style="border: 0px solid; text-align: center"
|-
| 3A || 3B || 3C || 3D || 3E || 3F
|-
| 40 || 41 || 42 || 43 || 44 || 45

|-
| 4C || 4D || 4E || 4F || 50 || 51
|-
| 52 || 53 || 54 || 55 || 56 || 57
|-
| 58 || 59 || 5A || 5B || 5C || 5D
|}

Possible values are 00 to FF. Empty spaces must have a FF value in their corresponding offset.

The following are the rest of the offsets I know. There are holes in the numbering but I have no idea what they are. With the exception of '''scientists and technicians''', which are '''one byte each''', all values are 2-byte signed little-endian values (-32,768 to +32,767). Example: 05 00 should be read as 0005; FE FF should be read as FFFE (-2).

It should be noted that despite the range of values a two-byte signed field gives you, due to a [[Known_Bugs#Storage_Limit|known issue]], you cannot have more than 9,999 units of a given item in storage at any given base, regardless of what item it is.

'''0120-0123:''' I have no idea, any help would be appreciated.

'''0120:''' Mark the base as active. Bases which are dismantled or which have not been built have a value of 1. Active bases have a value of 0. If a base is dismantled, the only change to the record is this value. A new base will overwrite the first slot with a value of 1. It is possible to restore a dismantled base (Access lift removed) by setting this value to 0. The game will 'restore' the base to the configuration just before the access lift was removed, including inventory. --[[User:SeulDragon|SeulDragon]] 12:24, 11 July 2008 (PDT)

'''11, 13, 15:''' These are probably the high bytes for the Short, Long, and Hyper-wave detections respectively. Should always be 0 as a value of 100 (hex: 64 00) is perfect detection.

Logical values for the detection capabilities:

''20 short, 20 long:'' This base has large radar(s) only.

''30 short, 20 long:'' This base has small and large radar(s).

''100 hyperwave:'' This base has a hyperwave decoder(s).

The radar values can be set to 100 for perfect short range detection (presumably -- it definitely makes UFOs appear more often), but these reset to the correct values any time you complete a build in that base.

Possible values are 00 to FF. Empty spaces must have a FF value in their corresponding offset.

The following are the rest of the offsets I know. There are holes in the numbering but I have no idea what they are. With the exception of '''scientists and technicians''', which are '''one byte each''', all values are 2-byte signed little-endian values (-32,768 to +32,767). Example: 05 00 should be read as 0005; FE FF should be read as FFFE (-2).

It should be noted that despite the range of values a two-byte signed field gives you, due to a [[Known_Bugs#Storage_Limit|known issue]], you cannot have more than 9,999 units of a given item in storage at any given base, regardless of what item it is.

Here's the info for bytes '''5E-11E'''. The Record Number (Rec#) is used for e.g. [[PRODUCT.DAT]]:

'''16-39:''' The next offsets are arranged so they're easier to understand. They are for facilities in the base:

{| {{stdTable}} border="1" cellpadding="5" style="border: 0px solid; text-align: center"
|-
| 16 || 17 || 18 || 19 || 1A || 1B
|-
| 1C || 1D || 1E || 1F || 20 || 21
|-

|-
| 2E || 2F || 30 || 31 || 32 || 33
|-
| 34 || 35 || 36 || 37 || 38 || 39
|}

The possible values are as follows:
00 - Access Lift
01 - Living Quarters
02 - Laboratory
03 - Workshop
04 - Small Radar System
05 - Large Radar System
06 - Missile Defense
07 - General Stores
08 - Alien Containment
09 - Laser Defense
0A - Plasma Defense
0B - Fusion Ball Defense
0C - Grav Shield
0D - Mind Shield
0E - Psionic Laboratory
0F - Hyper-wave Decoder
10 - Hangar (Top Left)
11 - Hangar (Top Right)
12 - Hangar (Bottom Left)
13 - Hangar (Bottom Right)
FF - Empty

'''3A-5D:''' The next offsets represent the days until a facility is completed. They're set up the same way:

{| {{stdTable}} border="1" cellpadding="5" style="border: 0px solid; text-align: center"
|-
| 3A || 3B || 3C || 3D || 3E || 3F
|-
| 40 || 41 || 42 || 43 || 44 || 45

| 4C || 4D || 4E || 4F || 50 || 51
|-
| 52 || 53 || 54 || 55 || 56 || 57
|-
| 58 || 59 || 5A || 5B || 5C || 5D
|}

Possible values are 00 to FF. Empty spaces must have a FF value in their corresponding offset.

The following are the rest of the offsets I know. There are holes in the numbering but I have no idea what they are. With the exception of '''scientists and technicians''', which are '''one byte each''', all values are 2-byte signed little-endian values (-32,768 to +32,767). Example: 05 00 should be read as 0005; FE FF should be read as FFFE (-2).

It should be noted that despite the range of values a two-byte signed field gives you, due to a [[Known_Bugs#Storage_Limit|known issue]], you cannot have more than 9,999 units of a given item in storage at any given base, regardless of what item it is.

Here's the info for bytes '''5E-11E'''. The Record Number (Rec#) is used for e.g. [[PRODUCT.DAT]]:

'''0120-0123:''' I have no idea, any help would be appreciated.

0120—Mark the base as selectable by the user in the Base View screens. A value of 00 is selectable, any other value is not. 01 is the default for base slots which have not been built. Testing for status/value when a base is destroyed or dismantled not yet completed.
