UFO Structure

Ripped from Hatfarm / Chris Voss's great pages

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.

Table 1: Radar Ability Combinations
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.

If you destroy a facility or one is destroyed during a base defense mission, the value remains 00. This causes the paying for dirt bug, resulting in an upkeep of 80k per dirt square. Simply change the value of the destroyed/dismantled facility to FF to eliminate the bug.

If a facility is built and then dismantled, and nothing is built there afterwards, the game may crash showing an UFOpaedia entry when the day count reaches zero.

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 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 and RESEARCH.DAT:

0120: Active/Inactive Base. Inactive entries have a value of 1. Active entries have a value of 0. Creating a new base will overwrite the first inactive entry. If a base is dismantled, the only change to the record is this value so it is possible to restore a dismantled base (Access lift removed) by restoring this value to 0. --SeulDragon 12:24, 11 July 2008 (PDT)

0121~0123: 0120 is stored as an integer. These fields are the unused portion of that integer.
