(ci-dessous, toutes les nouveautés de la Version 1.2)

IL-2 Sturmovik
Readme file (English)

Warning

The 1.2ov is completely identical and compatible to the already released version 1.2 except that version 1.2ov has an open folder structure for radio chatter voice files and corresponding HUD messages (see Section 1 below)

This version (1.2ov) is not compatible with the previous version (1.1) of the game when playing online.
Both the server and client must have appropriate versions of the game (1.2 or 1.2ov) in order to connect.
You may experience mistakes in reproduction of tracks recorded in version 1.1, training and intro files. However the version 1.1 tracks are meant to be compatible with the current build of the game.

Notes on the Upgrade Installation

The 1.2ov upgrade may only be installed over Il-2 version 1.1 (or 1.1a). It is also possible to install it over version 1.2

======= Version 1.2ov Changes =======

1. Notes on Using, Modifying and Replace the Voice Files and Radio Chatter Text Messages

After the installation of version 1.2ov, the sound files of radio chatter can be found in the "Samples" sub-folder in the game root folder (the folder IL-2 was installed to). The voice files for specific sides are located in the following sub-folders:

Samples -> Speech -> DE - Blue Side (German)
Samples -> Speech -> RU - Red Side (Russian)

The files of the corresponding HUD messages texts (subtitles lines) can be located in the "i18n" sub-folder. Those are:

I18n -> hud_msg.properties - Contains subtitles lines for English version
I18n -> hud_msg_fr.properties - Contains subtitles for French version
I18n -> hud_msg_de.properties - Contains subtitles for German version

All these text files are in UNICODE format. While the English version can easily be edited with Notepad, it may require a UNICODE-supporting text editor to write lines in other languages, specially when you're intending to use umlauts, hieroglyphs, Cyrillic alphabet and so on. The edited file should be saved in TXT format. Please always remember that the left column of this text is the names of files and the right column is the messages that will be displayed on the screen simultaneously with the sounding the voice files, so do not change the left column.

2. Main Rules of Edition of Files and Texts:

1. Do not rename the files. The names must be kept original despite the changes of contents.
2. Do not change the left column of the text files - it contains the file names for the program's internal usage.
3. Do not change the meaning of the phrases in the subtitles. Otherwise, you'll get a wrong working chatter generator, with rubbish or meaningless dialogs.
4. The sound files must be in the 11025 Hz, Mono, 16-bit format. To be used in IL-2 1.2ov they must be converted into Windows RIFF wave files (*.wav). The file data format must be MPEG-1 Layer 3 @ 20 kbps 11025 Hz Mono. This can be achieved using the appropriate sound editor, such as Sonic Foundry, SoundForge, Sonic Foundry Batch Converter, CoolEdit, e.t.c. It is up to you to decide which one to use, just be sure that the output format files meet the IL-2 requirements.

3. Radio Chatter Generator Rules

We provide a number of documents for every voice actor in the game in order to help you understand the system of phrase generation. However, we can't list all the possible combinations of sound phrases due to enormous amount of them, so we put the explanation of basic rules and common samples of speech into each document. It is quite self-explanatory and very easy to understand.
The doc files may be found in the root directory of IL-2 (the folder the game was installed into) after the installation of this add-on. The file name is "RadioChatter.zip".

Please be aware that you change the contents of the files at your own risk. Please keep back-ups of both "Samples" and "i18n" somewhere on you hard disk in case some of your changes may go wrong.

Junkers Ju-87 B-2

3D Model: Jury Shubin.
Skin: Jury Shubin.
Cockpit: Jan Niukkanen, Roman "Mad Dragon" Deniskin.

3. Notes on the New Yakovlev Fighters

The Yakovlev Yak-9, succeeded the Yak-1 and Yak-7, was the most produced type of the VVS front-line fighters. New M-105PF engine allowed it to reach maximal speed of 520 km/h at sea level, and 599 km/h at 4.3 km.
Yak-9D was a long-range version of the Yak-9 fighter, with fuel reserve increased up to 880 litres. The maximal speed at sea level was 535 km/h, with 591 km/h at 3.65km.

4. Notes on the Messerschmitt Bf-109 E-7/Z Fighter

The Bf-109 E-7/Z was a version with the DB 601N engine equipped with a high-altitude nitrous oxide injection system (GM-1). The system was prohibited to use under 6500 meters because of imminent damage to the engine, but in case of emergency it could provide extra 80 km/h of speed for a short period of time above 5.0 km.
In this version (1.2) the GM-1 boost system is activated when you engage WEP mode on the engine (W key by default). Avoid engaging the system on altitudes below 6500 m.

5. Notes on the Junkers Ju-87 B-2 Dive Bomber

The aircraft is equipped with a dive autopilot to assist a pilot in dive attacks.
The autopilot control is linked to the 'Airbrake' control key - You'll have to assign a key for it in the 'Controls' menu. Once engaged, the autopilot puts the aircraft into the diving configuration - as the dive brakes are extended, it trims the plane nose-heavy; plus, the diving sirens are switched on automatically. Once You have released Your bomb load (or when You get below a certain altitude, around 550 meters), the autopilot renders the aircraft tail-heavy to assist recovering from the dive.
Retracting the dive brakes (hit the 'Airbrake' key again) disengages the autopilot, and switches off the sirens.
The rear gunner is equipped with a magazine-fed machine gun, with provision for 1050 rounds in 75-round drums (Junkers manufacture data). Currently, You may see four drums in the locks to the left of the machine gun. These will disappear, simulating reloading the gun, as you deplete your last four drums of ammunition, giving you visual clue you have less than 300 rounds left.

6. Recommendations

1. For those who experience difficulties controlling aircraft with the default joystick profile (axis sensitivity curves in the Input menu), we provide sensitivity curves that we found more suitable for most of the modern input devices.
To set up the curves, go to the Input menu under the Hardware Setup in the Main Menu, and adjust the values according the following chart:

Pitch:
0 5 10 17 25 33 43 54 71 100
Roll:
0 3 7 15 25 35 50 66 84 100
Yaw:
0 8 19 29 39 51 62 75 86 100

7. Changes and Additions

1. The FW-109 A-4 altitude indicator now has the coarse dial operating properly.
2. Corrected speeds for the Yak-1, 1941 model. The corrected maximal speeds now are: 472 km/h at sea-level, and 569 km/h at 4.86 km.
3. As computer disk system may cause lags when repeatedly taking screenshots, in order to improve stability of the on-line gaming, the ability to take screenshots was limited to one per 10 seconds when playing on-line.

Unfortunately, we were unable to implement more additions or modifications since the team is busy with the Forgotten Battles upgrade, and most of the major modifications are scheduled for the Forgotten Battles project.

3. Notes on Flying the I-16

The I-16 fighter differs in handling from the more modern aircraft found in the sim.
First, it has no engine starter, so the engine can only be started on the airfield (with the help of the ground crew). Do not switch off the engine in flight or when making temporary stops.
Secondly, you can only operate the landing gear manually as it is not equipped with hydraulic or pneumatic system. To operate the gear, you need to assign two buttons in the Controls menu, Lower Gear Manually and Rise Gear Manually. To raise the gear, press the Rise Gear Manually button repeatedly until the red lamps on the dashboard go off. To lower the gear, keep pressing your Lower Gear Manually button until the green lamps come on.
I-16 is not equipped with trim controls of any kind. Control surfaces are calibrated for a hands-off flight at cruise power setting at 1,000 meters and 300 km/h. At other speeds and altitudes you may need to apply constant pressure on the controls to maintain level flight.
I-16, as most other fighter-bombers, is not equipped with a bombsight and therefore is incapable of high-altitude level bombing. However, fighter-bombers will drop bombs in a level flight. If you set a GrAttack waypoint at 3,000 meters for a bomb-equipped I-16, Bf. 109E or most other Jabos, that's the altitude from which the bombs will be dropped - and their chance of hitting anything will be very small. When creating missions for fighter-bombers with bombs, make sure that their GrAttack waypoint is at altitudes no higher than 500 meters.

4. Notes on the new MiG-3 Fighters

There were 315 UBS-armed MiG-3s, and 52 MiGs with dual ShVAK cannons produced.
The MiG-3 version with the AM-38 engine is a field modification based on the two prototypes evaluated in mid-1941. Due to the increased power and lower critical height of the new engine this version shows better performance at altitudes up to 4.0 km (with speed of 547 km/h at sea-level, and 592 km/h at 3.4 km).

5. Notes on the "speedbar" Command

The server hosting an on-line game now has an ability to disable using the so-called speed bar feature - the digital information display located in the lower left corner of the screen. The command syntax is:
speedbar [SHOW|HIDE]

If you want players connected to your server not to use these digital instruments, issue speedbar HIDE.
You can type in speedbar SHOW to restore back the default settings and allow players to use the speed bar.

6. Notes on the Event Logging

Any user participating in an online co-operative game, or playing in single-player mode, may now enable logging of events into a text file. To do so, add a eventlog key under the [game] section in the conf.ini file.

E.g.:
[game]
eventlog=coop.lst

In this case, all major activity will be logged into 'coop.lst' file, and may be reviewed later (i.e. with help of the Notepad).

In addition to this, when playing a co-operative mission, the current status of every player in the game is automatically logged into this file at the end of the mission (with score, kills, and dead/alive state), including players that left before the mission ended.
The AI units names are their 'mission' names and basically intended for log-parsing software.
The number in brackets after an aircraft name (i.e. r01011(0) ) represents an individual crew member of the given aircraft (with 0 being the pilot, 1 - co-pilot or rear gunner, and so on).
