Note: there are no entries for the Sectopod or Cyberdisc terrorists. Also, the
three tank entries are not used by the game. If you hack RESEARCH.DAT to open
these as research possibilities, the title of the research project will be "NOT USED."

== Structure ==

Each record in RESEARCH.DAT consists of 22 bytes. In what follows, the hex offset
is written in bold, followed by a description of the purpose of the byte(s).

00-01: The first two bytes determine the amount of time it takes to perform
the research, written low-high (for example 12 34 refers to the hex number 3412).

02-04: These three bytes determine the name of the research topic as it
appears on the Current Research screen in the game.
The table below shows how different
types of research are coded:

{| border="1"
! 02 !! 03 !! 04 !! Description
|-
| 00 || 00 || 00 || Laser Weapons
|-
| 31-3D || 00 || 00 || Alien Artifacts
|-
| 41-4B || 00 || 00 || Alien Autopsy
|-
| 50-58 || 00 || 00 || UFO Components
|-
| 00 || 01-0B || 01-07 || Live Alien
|-
| 00 || 00 || 01-1d || X-Com Craft and Armaments, Heavy Weapons Platforms, Base Facilities, Alien Research
|}

Note that, for live aliens, bytes 03 and 04 determine the alien's species and rank,
respectively, with the same convention as in [[ASTORE.DAT]]. Also, for Alien Autopsy
researches, the second bit of byte 02 determines the species.

Also note that, in addition to determining the name of the research project
for the purposes of the Current Research control screen, these bytes also determine
what object, if any, needs to be on hand in order for the research to begin.
Namely, if either or bytes 02 or 03 are non-zero, the research requires that
the named object be in the base's stores in order for the research to be listed.

05: non-zero only for some live aliens. It's meaning is uncertain.

06: with the exception of 0B which is unique to Laser Weapons research, indicates the category in the UFOpaedia into which the topic falls:

00 = X-Com Craft and Armament
01 = Heavy Weapons Platforms
02 = Weapons and Equipment
03 = Alien Artifacts
04 = Base Facilities
05 = Alien Life Forms (corpses)
06 = Alien Life Forms (live aliens) and Alien Research
07 = UFO Components
0B = Laser Weapons

07: determines the specific UFOpaedia entry, within each category, that
the research unlocks. In the case of live aliens, this byte contains
their race.

08: determines the number of points awarded when the research is completed.

09: seems to always be 00.

0A: is a boolean flag indicating, when true, that the research has been
completed and cannot be repeated. For research topics that can be repeated (e.g., research
on living aliens), this byte is always 00. Manually setting this byte to 01, however,
does not in any way give the player credit for completing the research - it will not
be unlocked in the UFOpaedia, nor will production options be made available. It
is simply to prevent a topic from appearing in the list of available research topics
once it has been completed.

Bytes 0B-0D are 00.

0E: a boolean value indicating whether or not the research topic
requires one or more prerequisites. It is true when there is not a prerequisite.

Bytes 0F-11 are 00.

12: a boolean flag indicating that the prerequisites have been
fulfilled. It is true when either the prerequisites have been satisfied or there
are no prerequisites and false when there is a prerequisite which has not been met.
Changing this value is a way to get around prerequisite research topics.

Bytes 13-15 are 00.

== Cheats and Hacks ==

First, what you cannot do with RESARCH.DAT: there is no way to modify this file to instantly
get credit for completing research, open UFOpaedia entries, or unlock production capabilities.

Things you can do, if you so choose:

*Modify the time required to complete research (bytes 00-01). Note that this is the initial time, not the time remaining on research you've already started. For that, see [[PROJECT.DAT]].

*Modify the points you obtain by completing the research projects (byte 08).

*Make research projects available without completing their prerequisites (byte 12).

*Eliminate the need to possess an object (either artifact or live alien) before researching it. Warning: this one's a bit odd: change bytes 02-04 to 00 00 11. This will make "NOT USED" appear in the list of research topics (it is the name of the Laser Cannon Tank - a project not used by the game). Research "NOT USED", and once it is completed, you will have access to the UFOpaedia entry access to any research that is lower in the research tree, and access to the relevant production capabilities.

ASTORE.DAT

2006-12-29T01:59:16Z

Radar99: Added information for Enemy Unknown

ASTORE.DAT contains information pertinent to live aliens in confinement.

== Structure ==
ASTORE.DAT has a fixed size of 50 entries of 12 bytes each. Information below is arranged by the byte's hex offset, in bold.

00: Alien race:
01 = Sectoid
02 = Snakeman
03 = Etherial
04 = Muton
05 = Floater
06 = Cellatid
07 = Silacoid
08 = Chryssalid
09 = Reaper
0A = Sectopod
0B = Cyberdisk

When an alien is researched, its race is set to 00.

01: Rank:
01 = Commander
02 = Leader
03 = Engineer
04 = Medic
05 = Navigator
06 = Soldier
07 = Terrorist

02: Base at which the alien is imprisoned, using index values from [[LOC.DAT]], your original base is always 00.
A value of FF indicates that the alien is being transferred.

03-0B: It is unclear what, if anything, these values do. 0B gets set to 01 when an alien is in transit
(this is in addition to setting the Base byte to FF). Otherwise, these bytes tend to remain 00.

== For TFTD ==

ASTORE.DAT
1st BYTE Alien type
01h Aquatoid
02h Gill Man
03h Lobster Man
04h Tasoth
05h Calcinite
06h Deep One
07h Bio-Drone
08h Tentaculat
09h Triscene
0Ah Hallucinoid
0Bh Xorquid

2nd BYTE Alien class
01h Commander
02h Navigator
03h Medic
04h Technician
05h Squad Leader
06h Soldier
07h Terrorist

These values define the alive aliens that we have in the base. The two values (one for the type and one for the class) must be entered in the first two bytes of the file. After the project has started or the aliens have been transferred to another base, the first byte will be 0. You can re-enter a new value to have other aliens.
