BASE.DAT
Ripped from Hatfarm / Chris Voss's great pages
Structure
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.
| Radar Module / Scan Type | Short | Long | Hyperwave |
| Small Radar | 10 | 0 | 0 |
| Large Radar | 20 | 20 | 0 |
| Hyperwave | 0 | 0 | 100 |
| Radar Combinations | |||
| Sm + Sm | 10 | 0 | 0 |
| Sm + Lg | 30 | 20 | 0 |
| Sm + Hyp | 10 | 0 | 100 |
| Lg + Lg | 20 | 20 | 0 |
| Lg + Hyp | 20 | 20 | 100 |
| Hyp + Hyp | 0 | 0 | 100 |
| Sm + Lg + Hyp | 30 | 20 | 100 |
16-39: The next offsets are arranged so they're easier to understand. They are for facilities in the base:
/-----------------------------\ | 16 | 17 | 18 | 19 | 1A | 1B | |-----------------------------| | 1C | 1D | 1E | 1F | 20 | 21 | |-----------------------------| | 22 | 23 | 24 | 25 | 26 | 27 | |-----------------------------| | 28 | 29 | 2A | 2B | 2C | 2D | |-----------------------------| | 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:
/-----------------------------\ | 3A | 3B | 3C | 3D | 3E | 3F | |-----------------------------| | 40 | 41 | 42 | 43 | 44 | 45 | |-----------------------------| | 46 | 47 | 48 | 49 | 4A | 4B | |-----------------------------| | 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. All possible values are 00 to FF, but when you go over 32,766 on 2-byte values, the number goes negative. And if it's two bytes then the first byte is the low bit and the second bit is the high bit. Example: 05 00 should be read as 00 05. The first two (Engineers and Scientists) are one byte; all the rest are two bytes. Here's the info:

011F-0123: I have no idea, any help would be appreciated.
