BASE.DAT (TFTD)
Structure
BASE.DAT: Each entry is 296 Bytes long.
Name
00-0E: Base Name, pretty obvious.
0F: Null character if the Base Name uses all 15 characters. If this byte is non-0, the base name will happily overflow and read from the item quantities.
Stores
10-D3: Quantity of each item available at that base (signed 2-byte little-endian integers; see explanation in UFO section for details).

Base Detection Values
D4: Short range detection value (%).
D6: Long range detection value (%).
D8: Transmission Resolver detection value (%).
Each base detection value byte is a low byte, followed by a high byte which is null (x0).
Detection values are identical to XCom1:
Possible decimal values are 0/10/20/30 for Short, 0/20 for Long, 0/100 for Transmission Resolver. The XCom1 Radar Stacking Bug still applies - there is no detection advantage to building multiple detection modules of the same type.
Facilities
DA-FD: The next offsets are arranged so they're easier to understand. They are for facilities in the base:
| DA | DB | DC | DD | DE | DF |
| E0 | E1 | E2 | E3 | E4 | E5 |
| E6 | E7 | E8 | E9 | EA | EB |
| EC | ED | EE | EF | F0 | F1 |
| F2 | F3 | F4 | F5 | F6 | F7 |
| F8 | F9 | FA | FB | FC | FD |
The possible values are as follows:
00 - Air Lock 01 - Living Quarters 02 - Laboratory 03 - Workshop 04 - Standard Sonar 05 - Wide Array Sonar 06 - Torpedo Defences 07 - General Stores 08 - Alien Containment 09 - Gauss Defences 0A - Sonic Defences 0B - P.W.T. Defences 0C - Bomb Shield 0D - M.C. Defences 0E - M.C.-Lab 0F - Transmission Resolver 10 - Sub Pen (Top Left) 11 - Sub Pen (Top Right) 12 - Sub Pen (Bottom Left) 13 - Sub Pen (Bottom Right) FF - Empty
FE-121: The next offsets represent the days until a facility is completed. They're set up the same way:
| FE | FF | 100 | 101 | 102 | 103 |
| 104 | 105 | 106 | 107 | 108 | 109 |
| 10A | 10B | 10C | 10D | 10E | 10F |
| 110 | 111 | 112 | 113 | 114 | 115 |
| 116 | 117 | 118 | 119 | 11A | 11B |
| 11C | 11D | 11E | 11F | 120 | 121 |
Possible values are 00 to FF. Empty spaces must have a FF value in their corresponding offset.
Personnel
0122: Number of technicians (00-FF).
0123: Number of scientists (00-FF).
Other
0124: Disabled flag, if 1 the base is disabled, if 0 the base is in use. 0125-0127: Unknown.
