.ARM (army) files contains a list of regiments, their status, and some army data and statistics. The same format is used for multiplayer armies, single player mission enemy armies and save games. Edit with Mikademus' DOS WH2EDIT editor or Ghabry's multi-platform Wh32Edit.

Contents


Layout overview

The .ARM format is a binary format, the layout of which is very simple from a large-scale perspective: It starts with a 192 bytes header, which is followed by several 188-byte regiment records.

Header

The header of a army-file has a size of 192 bytes. Example (Allied1.arm):

    00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F

Savegame Header

A savegame is in short an army file with an additional header located before the army header (and with lots of unknown data after the regiment data)

The Save files (*.[0-9]{3}) header has a size of 504-byte. Most parts of it are unknown.

At least the following things must be in the Save file (if you find out where they are please mark them in the example):

  • Your current progress
  • Your success in defeating Manfred von Carstein (defines if Black Pyramide MB5_01 or MB5_01B are loaded at the end), the Hand of Nagash or the Black Grail (they will help the Dread King when you lose) - OT: Looks like CTL scripts can read savegame data or is this just a special parameter passed by the engine when loading the map?
  • Path you've choosen e.g. in Chapter 3 (Hand of Nagash): If you help Munz or Ragnar you will lose time and more undeads will attack you in the Hand of Nagash mission (is this confirmed? At least Matthias and Klaus say this)
  • Used/Killed/Lost Units (for the stats page displayed after the battle)
  • Play Time (maybe ^^)
  • ...

Example (Endgame Save (Dread King defeated)):

It looks like the savegame header uses "32bit Booleans" to determine what kind of events happened.

Regiment data

For a complete list of all Dark Omen regiments, see Regiment List

Regiment data starts at offset 192 (in savegames offset 696). Every regiment block has a size of 188 bytes. Example first regiment from B403NME.ARM:

Soldier and leader Character Attributes

Further information: The Warhammer Attributes

The attributes for rank-and-file and leader units are nine bytes in the following order:

  1. Movement
  2. Weapon Skill
  3. Ballistic Skill
  4. Strength
  5. Toughness
  6. Wounds
  7. Initiative
  8. Attacks
  9. Leadership

For a complete listing of all data of every single unit in Dark Omen, see this big honking list (Warning! 800KB of pure table madness!).

Regiment attributes

Regiment attributes are physical and psychological abilities or disadvantages of entire regiments. Attributes are stored in the regiment block at bytes 16-19. The different values are flags mapped to bits in four bytes (thus 32 unique attributes are possible).

Transcluded from DO/ARM/Regiment attributes

Note: The Bits in this table are going from lowest to highest bit. So the lowest bit is 1 and the highest 8.

Bit BYTE 1 BYTE 2 BYTE 3 BYTE 4
1
Will never rout
Flagellants, steam tank and most undead have this
Immune to fear, can be routed
Most undead have this
Inflicting casualty causes fear

Destroyed if routed
Wights, wraiths, zombies, Carstein and dummies have this
No retreat, no surrender!
No regiment uses this. Unit will never rout, retreat button without any use. Banner of Defiance and cheat code DONTMESSWITHME and Ctrl+C+I have the exact same effect
4

Highly likely but not tested
Function basically undeterminable... :(
Guess and/or untested
I changed "psychology" to "attribute". I originally used the term psychology when I started mapping out the .arm files, and I thought that only the Warhammer psychology stuff (like hatred, saga animosity, fearless, etc) were stored there. But as also physical stuff like terrain striding etc are represented here "attributes" is a more descriptive term. Mikademus 23:24, 18 September 2008 (UTC)

I have started colour-coding the above table. Since it has been a while I am not certain which attributes I definitely determined and which I merely surmised. Ghabry is the the current authority on unit attributes, and I hope he will be able to complete the chart. Mikademus 12:43, 19 September 2008 (UTC)

Certain or likely flags

Flag #9 (byte 2 bit 1): In DO only skeletons have this set. It seems to be the undead army list rule that skeletons (which are immune to fear and don't take rout tests) take additional wounds from being pushed back

Flag #24 (byte 3 bit 8): This is an adaptation of Warhammer's special Screaming Skull Catapult rule. The Screaming Skulls fired by the catapult cause fear, so if even one casualty is dealt the receiving unit must take a rout test. Since Hand of Nagash also has this is is surmised that is is also used to give extra oomph to his attacks, and in extension, to the attack of any unit with this flag.

Uncertain flags

Flag #3 (byte 1 bit 3): Only goblins have this set. It could simply to indicate race, or it could be to indicate goblins' racial traits. The WHTTv4 rules about goblins are:

Races/Warhammer/Goblins/WHTT4

logo4thedminimalrn6.png

Relevant WHFB TT goblinoid rules v4. Goblins

  • have animosity toward other goblinoids
  • hate dwarves (and gnomes)
  • fear elves (of numbers > half the goblins)
  • and some special stuff about being led by snotlings and substituting spells.

Flag #4 (byte 1 bit 4): Only elves have this set. It could simply to indicate race, or it could be to indicate elves' racial traits. The WHTTv4 rules about elves are:

Races/Warhammer/Elves/WHTT4

logo4thedminimalrn6.png

Relevant WHFB TT v4 elves rules. Elves

  • are feared by Goblins if less than twice the numbers
  • have double encumbrance from armour

Wood elves

  • Suffer no movement or manoeuvre penalties in wooden areas
  • have 6" longer range with bows
  • and some special stuff about being substituting spells.

Are elves equipped with the same longbow (missile weapon type) as f.i. Helmgard Longbowmen? If so then we know that at least the additional distance rule applies.
