THE STRUCTURE OF EAW

EAW has its data in files in a series of library Compact Data Files (*.cdf). The constituent files can be extracted with Paulo Morais' CDF Extractor from EAW Online. An individual file in the EAW directory will be used by EAW in preference to the original in a CDF file. The CDF files are:

 

CDF File Size Contents

3d.cdf 4.66 Mb 3D cockpit and other views (*.3DZ)

cockpits.cdf 19.9 Mb Cockpit views of flyable aircraft (20x *.CPT)

data.cdf 1.36 Mb Aircraft and weapons data

flt.cdf 38.6 Kb Flight models (30 x *.FLT files)

fonts.cdf 1.01 Mb

grbrief.cdf 9 Mb

menu_eng.cdf 36.9 Mb

movies.cdf 284 Mb Movie files

music.cdf 1.38 Mb

pic.cdf 25.1 Mb Pictures, incl hangar pictures (*.MPC)

sound.cdf 1.14 Mb

sound16.cdf 2.38 Mb

speech1.cdf 9.94 Mb US speech *.SND files

speech2.cdf 11.3 Mb UK speech *.SND files

speech3.cdf 11.8 Mb German speech *.SND files

sprites.cdf 244 Kb

terrrain.cdf 7.57 Mb

text_eng .cdf 164 Kb Text string files (93x *.STR) for text within the sim

ukbrief.cdf 9.63 Mb

usbrief.cdf 11.4 Mb

wsound.cdf 8.87 Mb

wsprites.cdf 23.9 Mb

 

Hex to Decimal numbers are:

1 - 9 A B C D E F

1 - 9 10 11 12 13 14 15

 

EAW NUMBERING

Most EAW files use the Intel low-byte/high-byte format for numbers i.e. 3E8 is stored as E803.

Some (e.g. the *.FLT files) use a combination of short, long and float format (byte = 1-byte integer, short= 2-byte integer, long=4-byte, float=4-byte).

 

Hexworks has a Hex-Decimal calculator, a Data Viewer, and a Base Converter (Intel Hex-Decimal). The Windows calculator (Scientific mode) converts Hexadecimal-Binary etc

 

OTHER CHARACTERS

When hex editing text strings, the ASCII characters for German vowels with an umlaut are:

a 84 e 89 o 94 u 81

A 8e E O 99 U 9a

 

CREATING NEW FLYABLE AIRCRAFT

A basic new flyable aircraft requires 3 things:

1. Hangar picture (*.MPC)

2. Out-of-cockpit view file (*.CPT) and 6x Virtual Cockpit view files (5x*.3DZ & 1x VCG_xxxx.DAT)

3. Assigning the aircraft to a squadron, e.g. the Ju-87 Stuka to, say, EGr210 (in SQGR40.DAT)

 

COCKPITS.CDF: 2D COCKPITS

This file contains 20 *.CPT files, of variable length but each approximately 1 Mb. These are the out-of-cockpit views for each flyable aircraft. When creating a new flyable aircraft, take a suitable existing *.CPT file and re-name it (e.g. P191VIEW.CPT [bf-110] is re-named P261VIEW.CPT for the Ju-88C).

 

P001VIEW.CPT P38H

P011VIEW.CPT P38J

ARTWORK

The *.3DZ files contain the definition of the geometry data for the planes and are linked to a texture file. They refer to files with PCX as the file extension, which do not exist. There is, however, a file of the same name (e.g. P109EV.TPC) with TPC as the file extension. Microprose’ utility PICPAC.EXE creates TPC files from PCX files, enabling new aircraft skins to be created. The TEX files are a container for different kind of textures and that the 3DZ files are the geometry.

 

VIRTUAL COCKPIT FILES

3D.CDF has the various 3D files, including the Virtual Cockpit files. Five are needed, as follows:

 

Single engined aircraft

PxxxxU.3DZ Geometry and textures for the wings (single engine)

PxxxxV.3DZ Geometry and textures for the inner left part of the cockpit

PxxxxW.3DZ Geometry and textures for the inner right part of the cockpit

PxxxxX.3DZ Geometry and textures for the instrument panel

PxxxxZ.3DZ Geometry and textures for the gunsight

Twin engined aircraft

PxxxxV.3DZ Geometry and textures for the inner left part of the cockpit

PxxxxW.3DZ Geometry and textures for the inner right part of the cockpit

PxxxxX.3DZ Geometry and textures for the instrument panel

PxxxxY.3DZ Geometry and textures for the wings (twin engines)

PxxxxZ.3DZ Geometry and textures for the gunsight

 

xxxx is the code of the aircraft as per the *.FLT files.

The files VCG_xxxx.DAT (from DATA.CDF) are also needed. They contain the definition of the Virtual Cockpit gauges. Rename the files using the relevant code of the non-flyable aircraft.

 

3DZ FILES

The full list of 3DZ files is as follows:

File (e.g P109Ex.3DZ) References picture (*.TPC) file

PxxxxF.3DZ External picture PxxxxTEX.PCX

PxxxxH.3DZ Propellor and cowling PxxxxTEX.PCX

PxxxxL.3DZ PxxxxTEX.PCX

PxxxxM.3DZ Medium distance picture PxxxxTEX.PCX

PxxxxN.3DZ Bomber nose art

PxxxxP.3DZ Propellor spinner PxxxxTEX.PCX

PxxxxR.3DZ PxxxxTEX.PCX

PxxxxS.3DZ Long distance picture? PxxxxTEX.PCX

PxxxxT.3DZ PxxxxTEX.PCX

PxxxxU.3DZ Wings (single engine) PxxxxV.PCX

PxxxxV.3DZ Inner left part of the cockpit PxxxxV.PCX

PxxxxW.3DZ Inner right part of the cockpit PxxxxV.PCX

PxxxxX.3DZ Instrument panel PxxxxV.PCX

PxxxxY.3DZ Wings (twin engines) PxxxxY.PCX

PxxxxZ.3DZ Gunsight PxxxxV.PCX

 

PxxxxTES.TPC

PxxxxTRA.TPC

PxxxxTEX.TPC This is the only file different in the German version of EAW. The differences obliterate the swastika on the rudder.

 

Converting 1942 Pacific Air War (PAW) files to EAW

The format in PAW is similar. In EAW the 3DZ files are the 3D shapes, and the TPC files are the aircraft skins. The reference in the EAW *.3DZ files is to a PCX file, which does not exist in EAW - it is the TPC file of the same name. (This is a coding hangover from PAW, which does use *.PCX files)

 

In PAW the skin file is *.PCX, but this is not a regular PCX file, but obviously a Microprose file, with the same format as the EAW *.TPC files. The EAW *.TPC files are 256x256 size, but the PAW *.PCX files are only 256x128 size Using the corresponding PAW skin file, and re-naming it, gives an error message about "File the wrong size". For EAW, the *.TPC files have to be drawn from scratch over the PAW 3D shapes. The PAW 3DZ files are easier to convert. Change the internal reference to PxxxxTEX.PCX and change the file name itself as follows:

 

PAW file name EAW file name

xxx.3DZ PxxxxF.3DZ Main external picture

xxx_HALF.3DZ PxxxxG.3DZ (Right side, 2 or 4-engined planes only)

 

3xxx.3DZ PxxxxM.3DZ Medium distance picture

3xxx.3DZ (again) PxxxxN.3DZ (Right side, 2 or 4-engined planes only)

 

23xxx.3Dz PxxxxS.3DZ Long distance picture

123xxx.3DZ PxxxxT.3DZ Function not known

 

 

PIC.CDF: THE *.MPC HANGAR PICTURES

This file contains 20 *.MPC files, of variable length but each approximately 200 Kb. These are the hangar views for each flyable aircraft. When creating a new flyable aircraft, take an existing *.MPC file and re-name it (e.g. HNGR20.MPC [bf-110G] is re-named HNGR26.MPC for the Ju-88C).

 

HNGR00.MPC P38H

HNGR01.MPC P38J

HNGR02.MPC P47C

HNGR03.MPC P47D

HNGR04.MPC P51B

HNGR05.MPC P51D

*HNGR06.MPC B17F

*HNGR07.MPC B24D

*HNGR29.MPC V-1

 

* Not present, but needed if new flyable aircraft introduced.

 

 

TEXT STRING FILES (*.STR)

Text strings are found in the *.STR files, in TEXT_ENG.CDF. They are the simplest files to edit.

STR files include pilot names (AMRLNAME.STR etc), squadron names (SQNAMEGR.STR etc) and so on. STR files have a common format, as follows:

 

pppp Pointer to end of file (EOF = Pointer + 8)

nn00 Number of text strings

Then the pointers to each string:

p100 Pointer to 1st text string (add 8 to find string)

p200 Pointer to 2nd text string (add 8 to find string)...etc...

Then the text strings themselves, each separated by 00.

 

To change a text string, type the new string over an existing one, replacing any unrequired letters with 00. Alternatively, if a longer word is needed, add bytes to the file, and then adjust the pointers (including the EOF pointer). Paulo's utilities DUMPSTR.EXE and BUILDSTR.EXE now automate this task.

 

Text string files which I have amended include:

BRTLNAME.STR }

GERLNAME.STR } Last names for squadron pilots (the first names are in BRTFNAME.STR etc)

AMRLNAME.STR }

PNAMES.STR Plane names displayed in flight

SQDESCGR.STR }

SQDESCUK.STR } Narrative history of squadrons displayed when choosing squadron

SQDESCUS.STR }

SQNAMEGR.STR }

SQNAMEUK.STR } Names of squadrons displayed when choosing squadron

SQNAMEUS.STR }

RADIOTXT.STR Text of in-flight messages (incl gun desc. eg "20mm Cannon")

TARNAMES.STR List of names of places. At byte 0a43 after ZWICKAU is a list of airbases

TARTYPES.STR Generic target type names e.g. "Barracks", "Airfield" etc

 

 

 

FLT.CDF: THE *.FLT FLIGHT MODEL FILES

This file contains 30 *.FLT files, each 1284 bytes long.

 

Extracting the *.FLT files from FLT.CDF gives 30 *.FLT files, each 1284 bytes long. An extracted file can be simply re-named (e.g. the 190A.FLT file, after extraction, can be re-named 109G.FLT, and the Bf109G will then fly like the Fw190A). A better solution is to edit the files with Jeroen van Soest's EAW AircraftEdit program. The full names of the *.FLT files are as follows:

 

109E.FLT

109G.FLT

109K.FLT

110C.FLT

110G.FLT

190A.FLT

190D.FLT

FORMAT OF THE *.FLT FILES

Jeff D provided this information (short=2 byte integer, long=4 byte, float=4 byte, all C style). These figures are still very provisional:

 

Byte # (h)

//Engine data //Example

00 short number_of_engines //i.e. 1st two bytes

02 short engine_type //00=prop, 01=jet

04 float engine_altitude // Engine best at this altitude (e.g. P38H=22k feet, P38J=25k feet)

08 float unknown Horsepower at sea level (jets in lbs of thrust). This seems to be a sort of power loading factor, ranging from 0.00 (worst case, P38H) to -0.09 (best case, Tempest). Reduces time to lift-off

0c float unknown Horsepower at cruise altitude or max ceiling

10 float number_of_blades? 3 blades=0.006, 4= 0.007, 5=0.009, Jets=0

14 float min_throttle Engine torque multiplier (64 for all except jets, which are 25.6)

 

//Flight control data

18 (3 floats: max, min, rate) Throttle (P38H= 256, 0, 128)

24 (3 floats: max, min, rate) elevator (P38H= 128, -108, 256)

30 (3 floats: max, min, rate) flaps (P38H= 3, 0, 0.7)

3c (3 floats: max, min, rate) ailerons (P38H= 128, -128, 426)

48 (3 floats: max, min, rate) rudder (P38H= 128, -128, 275)

 

54 float max_altitude (P38H= 40,000 feet) Above this power goes to zero

58 float max_velocity Approx 1.5 x real max speed, see full notes below

5c float max_AOA

60 float critical_mach

64 float max_g Usually 9

68 float min_g All=3.0, except Hurr and Spit 1=0; max neg. g. for engine

6c float unknown

 

70 float mass_empty Multiply by 32.2 factor for combat weight in lbs

74 float mass_fuel

78 float unknown

7c float unknown

80 float unknown

84 float torque1?

88 float torque2

8c float torque3

 

//Bunch of coefficients for the flight equations : see detailed analysis below

90 (5 floats) drag stability

a4 (8 floats) sideforce stability

c4 (6 floats) lift stability

dc (9 floats) roll stability derivatives

100 (6 floats) pitch stablility derivatives

118 (9 floats) yaw stability derivatives

 

//The following section TIMES FIVE--lookup table data

13c long size Always 0a00=10 (5 Data curves. Each block is 0a00 0000, then 13 floats)

float delta_x 10=number of data points, at end of block. First 3 values may be data spacing and range of values

float inv_delta_x

float zero_x

float Table[10]

 

//The following section TIMES SIX--weapon data : see below (p. 15) for more detail

254 (3 floats) position x,y,z Gun flash position x, y & z co-ords

float secondary_position_x

float secondary_position_y

float muzzle_velocity 80% of real values

float rate_of_fire 1 second burst of fire for this weapon

float dispersion Important: reduces or increases effect for guns

float eject_position_1 //

float eject_position_2 //

short yaw

short duration of tracer or range

 

//Landing gear data

35c float height

360 float pitch (P38=0.063, B17=0.118, 110G=0.18, P51=0.19, 109E=0.24)

364 (3 floats: max, min, rate) gear_control

 

//This part times THREE (one for each gear)

float n

(3 floats) position x, y, z

 

//This part times SEVEN

(3 floats) damage position x, y, z

 

//This part times TWO

(3 floats) wing position x, y, z

 

//This part times FOUR

(3 floats) engine position x, y, z 4 Smoke positions

 

43c //Hit boxes/spheres

//This part times EIGHT Coordinates (x, y, z) and radius of hit boxes

(3 floats) hit locations x, y, z , plus float Radius

 

The known offsets here are:

 

1) 43c Single engined planes: engine (including oil & fuel lines). Multi engined planes: no effect

 

2) 44c Pilot

 

3) 45c Collision area: gun fire doesn't damage it. When disabled one can ram other planes without any damage. When enabled: collision can cause any damage independently of other hit boxes (e.g. even with pilot hit box disabled ramming a plane can kill the pilot)

 

4) 46c Tail section (incl. rudder and elevators)

 

5) 47c Right wing incl. hydraulics (four engined planes: inner right engine and wing)

 

6) 48c Right wing incl. aileron (four engined planes: outer right engine and wing)

 

7) 49c Left wing incl. hydraulics (four engined planes: inner left engine and wing)

 

8) 4ac Left wing incl. aileron (four engined planes: outer left engine and wing)

 

4bc long unknown

long radius_z

float engine_hit_points

 

These are quite similar to the damage table in PLANES.DAT. N.B. Byte 4a0 is the Microprose right wing error (inability to damage the left wing - the Y-coordinate is wrongly made the same as the right wing)

 

//This part times FIVE

4c8 (3 floats) position_of_weapons launch x, y and z coordinates of Weapons launch stations

 

 

 

MAXIMUM SPEED DATA IN *.FLT

The figure at byte # 58 regulates maximum speed The number is not the exact speed in MPH or in KPH, but the correlation is nearly linear. The equation is approximately:

EAW number = Real airspeed x 1.5

Real Airspeed = EAW number x 0.67

 

The figures are as follows (Dec=decimal value of Float variable, MPH=Maximum speed in m.p.h.(according to Microprose figures in EAW "View Objects"):

GUN DATA IN *.FLT

Paulo Morais decoded the FLT data related to aircraft guns. The file format for guns starts at byte #254 h (596 d), and is follows:

6 groups of 2c (44 d) bytes (one for each possible gun group) made up of the following 12 blocks:

 

1. 4 bytes (FLOAT) Gun flash x coordinate for first pair of guns in group

2. 4 bytes (FLOAT) Gun flash y coordinate for first pair of guns in group

3. 4 bytes (FLOAT) Gun flash z coordinate all the guns in group

FLIGHT CHARACTERISTICS

Use Jeroen's EAW AircraftEdit to change the FLT files.

Paulo has noted the following:

Byte 9c Drag Positive drag. Nearly linear to rated power. Increasing this increases acceleration.

Byte c8 Lift Wing area? Increasing the absolute value (e.g. -600 to -700) increases lift.

Bytes f0&f4 Roll related to engines (1, 2 or 4 engines)

Bytes 12c&130 Yaw related to engines (2 or 4 engines the same)

GUN CHARACTERISTICS: MUZZLE VELOCITY and RATE OF FIRE

EAW only provides for 4 types of guns (light MG, heavy MG, 20mm cannon and 30mm heavy cannon), but allows for different types to be carried by different aircraft. EAW also has a number of significant errors in weapons characteristics. The weapons figures are generally too low, both as to muzzle velocity and rate of fire. All muzzle velocities are too low -this makes for exaggerated trajectories (i.e. rounds falling away too early) . The rates of fire of the 0.50 cal MG and 20mm MG151 and Hispano MkII cannon are high (this exhausts ammunition loads too soon), while the ROFs of the MG81 7.92mm, MK108 30mm and Hispano MkV 20mm are low (this makes for low hitting power - not enough rounds per second hitting the target). The data is as follows:

Bomber guns (e.g. B17) are HALF the usual ROF.

 

 

The positions of the Muzzle velocity (MV) and Rate of Fire (ROF) figures in the FLT files are:

 

1st Gun Group Byte # 268

2nd Gun Group Byte # 294

3rd Gun Group Byte # 2c0

4th Gun Group Byte # 2ec

5th Gun Group Byte # 318

6th Gun Group Byte # 344

 

Changing the figures as set out above makes most fighter gun fire more lethal, because more rounds are fired per second. In dogfights, the "on target" ability of all guns is enhanced (because of the increased muzzle velocity), so less deflection is necessary. As of "Enemy Coast Ahead" Version 1.2 the muzzle velocities and rates of fire of all fighter aircraft now correspond with the actual data. Different weapons of the same calibre (e.g. the 20mm MG FF and MG 151) now have quite different firing abilities. Daniel Haeni did most of the research for this.

 

Gun Ranges

The ranges (byte #12 in each gun group) of the guns is as follows:

GUN CHARACTERISTICS: DISPERSION

This is an important figure. Dispersion is the maximum radius of bullet dispersion at some distant point, presumably linked to a random number. There are larger values for wing mounted guns, smaller ones for nose mounted (there are some real anomolies here, like the large figures for the nose mounted guns for the Bf109E, and the Spit IX MGs). To check this Paulo reduced this values to near zero in the 4x20mm equipped Hurricane IIc. The result was a systematic 12+ He111 or 10+ Ju88 bombers downed from distances higher than 600ft firing very sort bursts. Applying the reverse treatment, big values, result in having to close to 100ft to be able to down a single bomber.

 

The positions of the Dispersion figures in the FLT files are:

Note the generally pro-U.S. figures here (U.S. guns are generally much more concentrated than German and British ones). For ECA Version 1.3 I have made a number of changes to dispersion, as follows.

All bomber flex guns(B17, B24) are now 2.5

Bf109E nose MGs: 2.65 -> 1.627 (as per the Bf109 G & K)

added nose cannon 0.5 (as Bf109G&K)

Thes bytes control plane type, nationality, engine-sound, damage and other things, as follows. It is actually quite complicated. The bytes are bit coded. Take all four bytes and reverse the order (this is the normal procedure for storing integer data in IBM comaptible computers, ie: based on INTEL processors). For example, the P38H is 15 96 61 04. Reverse this to 04 61 96 15. This is comprised of the hexadecimal bits set out below.

 

NOTE “Attack Plane”. This must be set for planes that can fly bombing missions in campaigns and be escorted.

PLANES.DAT: DAMAGE

Starting at byte #48 h in each aircraft data block is a group of 12 single byte integers (short integer). In Paulo's opinion, supported by testing, is that these bytes are the number of "hit points" that some areas of the aircraft can sustain before failing.

1 - Fuselage mechanicals, fuel & hydraulic lines, Elevators & Rudder Not a critical failure.

2 - Pilot . Catastrophic failure.

3 - Fuselage structure. Catastrophic failure.

4 - Tail section. Catastrophic failure.

5 - Right wing structure. Catastrophic failure.

6 - Right wing mechanical parts. Aileron damage. Not a critical failure.

7 - Same as 5 for left wing. Catastrophic failure.

8 - Same as 6 for left wing Ailerons. Not a critical failure.

9 - Engine or leftmost engine.

10 - Right engine (bimotor) or inner left engine (quad)

11 - Inner right engine.

12 - Right outer engine.

I have now changes the Bf110C wings (5 and 7) from 32 (20 h) to 26 (1a h) and the engines (9 and 10) from 17 (11 h) to 12 (0c h).

The Fw190A3 has the following positions reduced:1 (17 to 16 d), 3 (34 to 28 d), 5 (25 to 24 d), 7 (25 to 24 d) and 9 (24 to 21 d). For EAW v1.2 (ECA v1.4 et seq) I have increased all armour levels by 50%.

 

 

PLANES.DAT: GUNS

After the damage byte is:

0x00 0000 Number of gun positions e.g. 0300 for P38H and J (Maximum is 8 positions)

Commences a4 bytes from start of block

then a series of 6 byte chunks, one for each gun

0n00 0p00 0t00 aaaa 0s00 0x00 where 0n=Number of guns

 

0p=Position Fixed: 0000=None

0100=wing 0200=nose

Defensive: 0300=tail 04=Top turret 0500=Rear cabin

0600=Top 0700=V Rear

0800=v Front 0900=belly turret 0a00=left waist 0b00=right waist oc=nose flexible od=Front turret

 

ot=Type of guns 00=None

02=.30 cal MG, 7.9mm MG

04=.50 cal/13mm MG

0c= 20mm cannon

18= 30mm cannon

 

aa=Ammo in reverse order e.g. f401=500 d

 

0s= Sound 00=.30 cal MG

01=.50 cal/13mm MG

02= 20mm cannon

03= 30mm cannon

 

0x=Smoke 00 or 01 (smoke or no smoke)

 

Only the first 3 groups are cyclable in the flyable aircraft, and each group is limited to 4 guns. Paulo Morais' file PLN_DAT.TXT contains a full dump of all 30 aircraft gun groups. Use Paulo's utilities DUMP_PLN.EXE and PTCH_PLN.EXE to change gun groups. The code 'ot' for the gun type also sets the gun destructive power. Higher values to simulate other guns can give spectacular effects. You can try to use 30h(equal to 2x the 30mm cannon value) for the 50mm cannon that equipped some Me410 versions. The downside is you can't get a meaningful text string (the in-flight text is in RADIOTXT.STR, and there are only 4 types per nationality), and the sound is limited to one of the 4 available sounds.

 

Then after all 6 x 6 byte gun chunks (including, usually, 1 or more 0000... ones):

 

UBYTE Max hit locations ? }Most fighters c611 fa5f and bombers 380e fa5f

UBYTE Max engines per plane? }All German planes 380e de58 or 380e fa5f

UBYTE Pitch limit?

UBYTE Yaw Limit

 

4 bytes nnnn nnnn Aircraft name e.g.110c, m410, mosq etc. Commences a4 bytes from start.

30h bytes 0000 All zeros.

 

To change guns, for example to fix the Bf-110G so that it has 2x20mm cannon and 2x30mm cannon:

1138 0400 0000 4 gun positions, no change

113c 0400 0200 0200 e803 0000 0000 (4x7.9mm MG in nose, 1000 rounds each)

1148 0200 0200 0c00 4501 0200 0000 (2x20mm cannon in nose, 325 rounds each)

1154 0200 0200 1800 8700 0300 0000 (2x30mm cannon in nose, 135 rounds each)

1160 0200 0500 0200 2003 0000 0000 (2x rear flex 7.9mm MG, 800 rounds each)

LOADOUT.DAT

This file is 9728 d bytes (2600 h) long. It controls the bomb and rocket loads on all 30 aircraft. The format of LOADOUT.DAT is:

b400 0000 b4 h = 180 d records, each is 2c bytes (44 d) long

1st group of records

152 actual records for the various aircraft follow, then 28 blank (all zero) records. Presumably there can be expansion here. Then:

 

2nd group of records

9600 0000 96 h = 150 d records, each 0c bytes (12 d) long, 5 for each aircraft. These controll which loadouts are available for which missions in Campaigns.

 

The 1st group of records (2c bytes long) have the format:

ac00 Aircraft code e.g. 0000=P38H, 0f00=Mosquito. Then 21 d 2-byte blocks as follows:

0n00 Number of blocks

The solution to the ordnance loadout/lockup problem is simply to change the new machines to be like (say) the Spit IX. The Ju-88 has 2 loadout options only (Guns i.e. No Load, and Bombs). The Mosquito likewise has only 2 options (although this can be changed by increasing the number of loadout options), and the Me-410: 3 options.

 

 

MISSION FILES (MISNxx.DAT)

There are Mission files: MISN40.DAT MISN43.DAT MISN44.DAT MISN45.DAT

Presumably these affect the aircraft available in missions in the various years.

Each file is 60 d bytes long, divided into 3 equal chunks of 20 d bytes.

This data in WEAPONS.DAT is interpreted, mostly by Paulo, as:

Byte

1-2 1=Weapons code 2=Type (00=none, 01=bomb, 02=rocket, 04=fuel tank)

3-4 Code to image of weapon after firing/dropping (e.g. 06=250 kg bomb)

5-6 5=Negative quantity multiplier (e.g. 0c for 500 lb bomb,change to o2 to increase sqn stockpile)

6=Initial relative forward speed (You can make bombs or tanks behave as rockets)

7-8 2 bytes (int) is Impact Damage.

9-10 2 bytes (int) (only for rockets) time length of rocket motor exhaust

11-12 2 bytes (int) (only for German rockets), self destruct time/distance

13-14 2 bytes (int) is Blast Damage.

15-16 Null

17-18 2 bytes (int) Flight performance penalty

19-20 2 bytes (int) Empty weight (lbs)

21-22 2 bytes (int) Full Fuel weight (lbs), only for drop tanks.

23-24 Null

 

In the original, the WGr21 rockets seemed to fly forever without exploding. Replace the 6th value (7805) (=1400 d) with the R4M value (bco2) (=700 d) and they explode sooner. I now use 9001 (=400 d), which makes them explode at a range of about 2,000 - 3,000 feet, which seems about right.

 

The Henschel Hs-293 rocket bomb (500 kg warhead) and Fritz-X rockets can be carried by the Ju-88C, and the Fritz-X by the Me-410. They are useful for anti-ship missions. To find ships, fly to Southampton or Portsmouth (for Allied ships) or Emden (for German ships). There should always be a convoy of 1-3 DD's and 2-8 merchant/troop ships. In June 1944 there are also Allied ships off the coast of Normandy. The Fw-190A and Me-410 can carry the Panzerschreck rocket (6 under each wing). The Panzerschreck is a light 54mm anti-armour (not air-to-air) rocket.

Paulo says that inside 3D.DAT there is a group of files ORD00-33.3DZ that contain the geometry definition, and pointers to bombs.tpc (the texture file), for the 34 different images for ordnance (weapons and mounts).

The coordinates for ordnance location are inside the main geometry definition file for each plane (PxxxF.3DZ)). Where? I don't know but it is a starting point. The five groups of coordinates at the end of the FLT file only define the launching point.

SQXXXX.DAT e.g SQGR40.DAT

There are 8 SQXXXX.DAT files which allocate squadrons:

SQGR40.DAT (and SQGR43.DAT and SQGR44.DAT)

SQUK40.DAT (and SQUK43.DAT and SQUK44.DAT)

SQUS43.DAT (and SQUS44.DAT).

 

The format is the same. Each file is comprised of a number of blocks, one for each squadron (e.g. 9 German squadrons in 1940), each 7c (124 d) bytes long. The format of each block is:

 

00-01 9x07 Year. 9407h=1940, 9797h=1943, 9807h=1944

02-03 om0d Start date Month/Day (00=Jan, 04=May, 06=July, 07=Aug, 0a=Nov, 0b=Dec)

04-05 bb00 Air Base e.g. 08=St Omer, 3c=Le Havre

06 aa Aircraft code see page 1, e.g. 00=P38H, 10=Bf-109E, 1b=Ju-87

07 0n Establishment of Pilots

08 0p Establishment of Planes

09-0b ffc800 3 bytes - (maybe pilot experience and morale?)

0c-0d 03 00 Number of possible squadrons/staffels that one can be assigned to

0e-12 pp pp pp pp pp 5 bytes - Probability (out of 100 h) of mission types:

Escort/Sweep/Bomb/Intercept/Interdict

e.g. 80 80 00 00 00= 50% escort, 50% sweep

10 40 b0 00 00= 6% escort, 25% sweep, 68% attack

00 40 40 20 60=25% sweep, 25% bomb, 12% int'cept, 37% interdict

13-15 uu uu uu Unit sign/Unit designation/Unit long description

16-19 0d 17 18 19 Squadron/Staffel designations

1a-1b 02 02 Number of airfield moves/number of aircraft updates (4+4 max)

1c-2b (4x 4 blocks) Airfield changes. Probability/Mission number in 25/Airfield number

(the ffff [65535] value is a mystery. It only happens in UK43-44, and may mean move to continental provisional airfields??)

2c-3b (4x 4 blocks) Aircraft upgrades. Probability/Mission number in 25/New Aircraft

e.g (Spit9->Typhoon->Tempest)

 

3c-5b 20 h (32 d) bytes of unknown flags.

 

5c (8x 4 blocks) Weapons stockpiles. Weapon code/First mission available/Amount

 

The alternative staffels you could be in in a particular Gruppe (see the number just before the mission probability types for quantity of choices). e.g. in SQGR40.DAT, III/JG 51 has 3 choices (byte 278=03).

Then starting at byte # 16 h are the name references: od 17 18 19.

These are references to the squadron names 0d, 17, 18 and 19 in SQNAMEGR.STR, namely III/Jagdgeschwader 51, Staffel 7, Staffel 8 and Staffel 9 respectively.

 

The first plane update is at byte # 2c.

e.g. 8017 1200 = upgrade to Bf-109K,

0000 0000 = no upgrade (e.g. all German squadrons in 1940).

 

Remember that the stockpiles are affected by the "negative multiplier" in WEAPONS.DAT.

 

The airbase code are set out on the following page. The names are in TARNAMES.STR. This list is in two parts, the second starting at 0a43 after ZWICKAU, which appears to be a list (not properly ordered, however) of airbase names.

18 Number of campaign's phases (see below)

19 Not known, but 1940 campaigns are 07, all others are 1e.

1a A mission every ... days (normal campaign setting doubles this value). This is sometimes affected by some other byte, because in the BOB (British side) between middle August - middle-September missions happen every two days, not three as at the beginning or end.

1b Number of types of available planes defined at offset 33c

 

1c Here begins part of the file that describes campaign phases. The entire part consist of 25 chunks, each 32(d) bytes long. 1940 campaigns use only 10 (d) of them. The entire part is 320 h (800 d) bytes long.

05-10 Always 0000 0000 0000

11 Not known, but is somehow connected with the area of operations

13-14 Not known (6400 or 08ff in 1940, all others are fa00)

15-20 Always 0000 0000 0000

21-22 Not known (values are 8000, c400, 4000 and ff00)

23-24 Not known

25 Target type (15h radar station, EE convoy, 05 airbase etc)

26 Not sure, but seems to influence target area

27-28 }

29-30 }as 25-26. A single phase can have up to four target types

31-32 }

 

Eg. in BOB the first four phases are each 7 days long and the only target type is convoy. The 5th phase is only 4 days long, but targets radar stations and airbases in SE England. Next phases concentrate on airfields in London area.

 

 

 

Then at Byte # 33C are the descriptions of aircraft availability. I am not completely sure what these files do, but they do control enemy aircraft appearing in missions. For example, in CAMPGR40.DAT at byte #37c the Ju-87 is as follows:

 

1B 00 04 FF 2C 01 00 00 00 00 00 00 00 00 00 00

 

1-2 Plane id (1B = Ju87) (located at byte #33c in CAMPGR40.DAT)

 

3 Withdrawal date, by phase (see above) (04 =4th phase)

 

4 Replacement plane (FF =none)

 

5-6 Probability of plane appearing in a mission AT THE START OF CAMPAIGN (2C 01 =300)

 

7-8 Always 0000

 

9-10 Prob of plane appearing after MID-CAMPAIGN date byte#3 (00 00 =none, as its withdrawn)

 

11-12 Always 0000

 

13-14 Prob of plane appearing after mid-campaign date IF the plane wasn't available at the beginning of campaign. (00 00 =none).

 

To make this a little clearer compare the above example to the Ju88A in 1940:

Type 1 3 5 7 9 11 13 15

109E=1000 19ff c800 0000 1000 0000 0000 0000

 

110C=1300 19ff 6400 0000 0800 0000 0000 0000

 

Ju88 =1900 19ff 0000 0000 0c00 0000 0000 0000

 

Ju87= 1B00 04ff 2c01 0000 0000 0000 0000 0000

 

H111=1c00 19ff 9001 0000 0c00 0000 0000 0000

 

In this case the Ju88A is available at the start but has no chance of appearing as bytes 5&6 are blank. But when it does appear in mid-campaign '0c' the probability is 600. It serves to the end of the campaign (phase 19 h =25 d) and therefore has no replacement = 'FF'.

 

The bytes after FF seem to refer to probability of appearance in missions. If you look at the numbers, you'll notice the bigger ones tend to appear more frequently. For example:

 

He-111s (9001=400 d) are more than Ju-87s (2c01=300 d). Hurricanes (2c01 =300 d) are more than Spitfires (6400 =100 d) . The 1940 campaign has no plane replacements but 1943 and 1944 campaigns do. The P-47C has the P-47D's ID in the fourth position. The P-38H has the J model. The P-51B has the D model. The FW-190A has the D model, etc....Curiously the Bf-110G has the ME-262 as its replacement.

 

 

At offset 580h are possibly the bytes that probably control escort type for bombers, but I haven't yet worked on them much.

 

 

CAREER0x.SVE

 

This information was worked out by Nick Bell. The files CAREER0x.SVE contains the data concerning each career pilot. It is found in the SAVEDATA subdirectory. (The 00 is the 1st pilot you created, 01 the 2nd and so on. This will change as you delete career pilots so just look at the top of the file where your pilot's name occurs.)

 

Changing Planes in a Career

It is possible to change one plane for another during a career. This works with planes on the same side only. If you change for an enemy plane your ground staff will shoot you up before you take off! Go to byte 00022fb6 h. If your present plane is a P51 it will be 04 (for example), and if a Bf-109E, 10. Change the aircraft code to the plane you want to fly.

 

Changing Pilot Names

In the same CAREER00.SVE file a little further down, at byte 235a5 h, are the names of all the pilots in your squadron. Just change the names to your liking by re-typing them.

 

Changing Aircraft Replacement Rate

Offset 143297 d (22fc1 h) in CAREER00.SVE is the byte for aircraft replacement, which sometimes is set at zero (e.g the British 1940 and 1943 campaigns). It can be changed from zero to a large number.

 

Changing the current number of planes

Losses? The current number of planes is in CAREERxx.SVE near the end.

Search for your staffelname and in among the next 'set' of hexvalues after it should be 06 ( at offset 00022FC1 ? ). Change it to 0C.

 

Nick Bell (nbell@icdc.com)has created a small editor for CAREER0x.SVE. It is available from his web page (http://www.photohosting.com/users/HKL/hkl.htm). The following is part of the TXT file that goes with it.

 

Edit Squadron Data

Remember that changing your squadrons aircraft to enemy types will cause your airfield AAA defenses to fire at you while on the runway. I’ve found that moving my Allied squadrons to France or Belgium after the invasion in 1944 was a pleasant change of pace and shortened my flying time considerably. There is no problem with escorting 8th AF formations flying out of England if you move to the mainland. The program recalculates the rendezvous point with the bombers to a point over Europe. You don’t have to fly back to England to meet them.

 

Edit Pilot Data

Fatigue and Morale: Let me start by saying I presume these are the pilot fatigue and morale values. Fatigue increases every mission. It increases a lot if the pilot bails out, and drops between missions if the pilot doesn’t fly. Setting the fatigue level to 0 improves the AI pilots performance, and apparently makes them much more likely to survive bailouts.

 

Morale increases a variable amount based on the success of the mission. Mission failure causes the morale value to drop. The most visible thing I’ve noticed with setting the morale to maximum (255) is that the AI pilots are more willing to engage for longer periods. As an Allied player this is useful, as it keeps the escorts more in the fight. As the German, this might not be such a great solution, as the AI pilots hang around longer and have a tendency to get shot down more as they make ineffective passes with MG’s only. Setting the German pilots to low(er) morale makes them make a few passes at the bombers and then the head home. This lessens their casualties, but doesn’t help them down bombers, either. Experiment and let me know what you think is a good value.

 

Sorties and Kills: Apart from being able to credit yourself kills you “know” you got, I have read that some players feel that AI pilots with very high sortie and kill counts are better. (note that although I know where the data is in the career file, I do not consider worth the time/effort to hack and code and editor for the pilot log, so changing your kill count is only on the scoreboard).

 

Rank: Along with fatigue, rank determines who flys and what position they fly in. Note that promotion points are also tracked. They are stored in one of those Unknown data types. I just haven’t bothered to figure it out. When I have set all unknown values to the maximum, pilots get promoted very quickly, so it’s there somewhere.

 

Pilot Status: I’ve never seen Wounded or Rescued on the Squadron Status Board, but they’re in there. Not sure of the effects. Would be interesting to see if wounded pilots “heal” over time. Note that Allied and German Pilots use different values for the same status. It might be interesting to put an enemy pilot in your squadron and see what happens. In any case, you can easily rescue/recover or bring back to life your favorite pilots.

 

According to the Microprose, selecting an ‘easy’ campaign gives the player better squadron members. In comparision between AI pilots created in easy campaigns vs those created in hard campaign, the easy campaign pilots have higher values.

The problem with MSN files editing is the first 4 bytes. Most probably are some sort of encoded checksum. If you take a look into EAW.EXE you will find references to a public key that could related with this problem or with the CD validity check.

 

 

 

 

EAW SOUNDS

Meatwater's Soundpacks (http://www.meatwater.de) have new sound files.

The sound files format is: snd00xx.snd

Paulo Morais has utilities for converting RAW format sound files to EAW format and vice-versa.

 

In Meatwater's Version 1.3 the files are:

snd0009.snd 35.1k Bomb whistle

snd0025.snd 906 bytes .30 cal MG

snd0026.snd 805 bytes .50 cal MG

snd0027.snd 1.03 k 20 mm cannon

snd0028.snd 1.49 k 30 mm cannon

snd0029.snd 34.8 k Rocket launch

snd0050.snd 183 k Gear up/down

snd0051.snd 74.5 k Parachute

snd0052.snd 32.9 k Touchdown

 

In Meatwater's Version 2.0 the files are:

snd0003.snd 67.8k Flak explosion

snd0004.snd 133k Bomb explosion

snd0009.snd 46k Bomb release whistle

snd0019.snd 45.2k Flak shot

snd0020.snd 37.6k Flak hit

snd0022.snd 128k Plane explosion

snd0042.snd 118k Other engines

snd0043.snd 69k Bomber engines

snd0044.snd 184k V-1 engine

snd0047.snd 292k Engine failure

snd0050.snd 183k Gear up/down

snd0052.snd 32.9 k Touchdown

 

grb_031.snd and gbrf.cdf 8963k German briefing

aradio1m.adp and aradio2m.adp } American Radio music

bradio1m.adp and bradio2m.adp }5691k British Radio music

gradio1m.adp and gradio2m.adp } German Radio music (incl Lilli Marlene)

 

I prefer the Version 1.3 .30 and .50 cal MG sounds, but otherwise the Version 2.0 sounds.

 

The SND file structure is made of a header part of 7 DWORD (28 bytes total length) followed by waveform data (RAW format in the sense of the program Wave Studio bundled with old SB cards. From the seven header parameters only 4 matter:

#3 - data size in bytes

#4 - sample rate (Hz)

#5 - resolution 8 or 16 for bits

#6 - 1 stereo, 0 mono

By using Paulo Morais' SND2RAW.EXE the header is striped and dumped to screen, and a RAW wave file generated to be edited by some compatible program. After that, using RAW2SND.EXE it is possible to obtain a file usable by EAW. These two DOS programs give some help if executed without parameters.

 

 

Conclusions

These notes are the result of a lot of detective work, trial and error and guesswork, by me and a number of others, most of whom are mentioned above. They have been collated over a period of time, and are a synthesis of everyone’s knowledge that has been shared to date.

 

If anyone else reading these notes wants to try their hand at editing EAW, give it a go and let me know. Cooperation is the key. But PLEASE back up anything before you do.

 

And, as the saying goes, if you cannot add and subtract in hexadecimal, you shouldn’t be hex-editing.
