| v1.00 CD
This document has information on the only two official MicroProse
EAW Team patches. For manual installation
instructions of the game see my
Install Help Document for more information. To read about the
quarks of different versions of the MPS game, see my
v1.1 and v1.2 Help
Document. If you find more changes between versions please let
me know as MPS only listed the most noticeable of them.
NOTES: About The Two Official Patches:
The official 1.2 patch includes everything from
the official 1.1 patch (everything
that the programmers wanted to keep. Some things introduced in 1.1
were apparently changed again in 1.2.) The bottom line is that it is
NOT necessary to install the 1.1 patch first, If you want to run EAW 1.2, all
you have to do is run the single 1.2 patch.
v1.2 EAW Team
- Official MPS Patch Release
(August 12, 1999)
- Special Thanks to Chris, Brandon,
Martin, QA and the Beta Testers for making 1.2 happen…
-Have a clean install of v1.0 or v1.1.
-Place the patch program in your EAW folder and run it. (You may
have to run it as an administrator)
primarily improves some multiplayer lag and warping problems,
but there are also some new features and functionality.
Bullet and Armor
Bullet modeling has been adjusted, so in
general bullets have more power. Additionally, Hurricane, 110,
410 and He-111 lethality and armor values were rebalanced.
New HUD feature: Next to the plane type in the targeting HUD, a
* character will appear (e.g. *Bf-109) if that aircraft is your
wingman, or a # if he is your squad leader. To change these
characters, add "WingmanChar=42" and "LeaderChar=35" to the [EAW]
section of the EAW.INI file, replacing these default numbers
with the desired ASCII code.
Combat tactics have been improved.
Tailgunners are now properly affected by
G-forces, and aren't always as accurate. It is still dangerous
to park yourself behind one, though.
After you bail out, ditch the plane, or land and shut off the
engine, you are now properly asked if you wish to exit. If you
choose to stay, you can use F9 or other view keys to watch the
rest of the action. Press Escape when you want to leave.
A crash bug involving ALT-N and some other
stability issues were fixed.
have been reduced, and a respawn/framerate bug has been fixed.
Lag and warping can still occur, though, so choose your
multiplayer sessions wisely. The faster the host's connection,
the less warping everybody else will have and the faster the
host's framerate will be. Also, the number of planes in the air
will affect lag and warping, so if the host has a slow modem
make sure (for example) that everybody picks the same plane type
(or two) to minimize the number of extra squadrons created. See
below for advanced host settings.
Version and Data
checks in Multiplayer:
You will not be
able to launch a multiplayer game unless everybody has the same
version of EAW (V1.2). Also, the aircraft flight data on each
machine is now encrypted online and compared to everybody
else's, so if anyone has different modifications or different
data than your own you will get a warning message. If everybody
has the same modifications, though, you will not get the warning
and will be able to launch.
Multiplayer (Coop) Missions:
If your plane is destroyed, you bail out, or
you are killed, you can jump into the next available AI plane in
your squadron by using the "Jump to next plane" (ALT-J) key.
ALT-J will not work if your plane is still flyable, or if there
are no AI planes remaining. (Or, if the host has "AllowRespawn=0"
set--see below). In any case, you can remain in the world and
watch everyone else with the view keys. Press Escape to exit.
are four new commands recognized in the EAW.INI file (usually found
in your Program Files/Microprose/European Air War folder; open it
with Notepad or another ASCII text editor). They are experimental,
however, so are not officially supported.
Add this under the [EAW] section to create
extra-large battles in most missions. The value can range from 0
(normal amount), to 5. The best values to try are probably 2 or
3 for a maximum number of planes in the air but still relatively
balanced on both sides. Values of 4 and 5 tend to create
encounters with more friendly aircraft than enemy, so the enemy
usually retreat sooner and you don't get attacked as often. The
ExtraSquads instruction isn't officially supported however,
because it could lead to a somewhat unbalanced dynamic campaign,
especially toward the end of the war. But, it does tend to make
encounters bigger and more intense.
Add this under the [Network Options] section
if you are the host of a multiplayer coop session and want to
prevent players from jumping into a new plane after dying or
bailing out (default is 1). This option doesn't appear in the
session details screen when everyone first connects, though, so
make sure everybody understands before you launch that they only
get one plane and one life (but can still stay and watch the
action if they get shot down).
Put this under the [Network Options] section
to have everybody in a multiplayer coop session start on the
This is not fully tested, and may cause strange results! Also,
with no time acceleration or ALT-N you will have to fly the
mission in real time. EAW will try to pick the closest bases to
the target, though).
While sitting on the ground, all of the enemy plane icons will
show up on the map, but once you lift off they will disappear
and you will have to rely on ground control or your own
reckoning to find them. The mission type will be what the host
selects in the multiplayer screen for his side; the opposite
side will have the corresponding opposite mission. And as usual,
players who select the same plane type will be put in the same
squadron at the same home base. The destination target area will
be what the host
most recently chose
Single Mission Setup.
Thus, to select
a specific target city as the host, prior to starting the
multiplayer session go into Single Mission, pick the same year,
plane type and mission type you'd like for multiplayer, pick a
target city, then exit out and start the multiplayer session. As
with AllowRespawn, you should make sure all participants know
they will be starting at home base instead of in the air, since
they will not see this setting in the options screen.
Put this in the [Network Options] section to
remove any AI planes from human squadrons in coop sessions.
Note, however, that without AI planes you will not be able to
respawn regardless of the AllowRespawn setting.
The following settings
are for advanced users used to hosting multiplayer internet
sessions. No adjustments should be needed in most cases, especially
for a LAN or cable modem connection, but you can change these values
anyway to optimize performance, by adding them to the [Network
Options] section. Ideally, you should have a connection speed of
about 10K baud for each player in a coop game, or less for Total
Mayhem. This is a very rough value, though, dependent on the number
of planes in the air, as well as factors like how close everyone is
to everyone else.
Maximum length of time (in milliseconds) that
EAW should expect to wait for the modem to accept the next
packet. If it takes any longer, it assumes the send buffer is
overflowed and begins scaling things back. If this value is too
low, it may scale back too much and players will get more
warping. If the value is too large, the host may not correct for
buffer overflows and could get long pauses in the framerate.
Length of time (in 70ths of a second) that
the host will stop sending packets when an overflow occurs, to
let the send buffer clear. This value can be lower (or zero) if
buffer overflows are just occasional, but if your system always
gets long pauses, this value should be around 50-100. If the
value is too large, packets will not be sent as efficiently as
possible, and players may see more warping.
Length of time (70ths of a second) to
increase the time interval for plane updates if the send buffer
overflows. If this value is too low, EAW won't adjust its send
rate in response to bandwidth problems very much, and if it's
too high it may overreact to a single situation (such as when 80
planes suddenly merge) and cut back too much, causing more
warping for other players.
When information changes for an aircraft, but
it is almost time for the regular scheduled update, EAW may
discard the change and just wait for the regular send to save an
extra packet. This value is a multiplier for how close in time
to the regular update to wait and just combine the two. It is
multiplied by the overflow adjustment intervals that have been
made so far, so if you have good bandwith (zero overflow), it
will always send these extra packets which reduces player
warping. If you have poor bandwidth it will send fewer if any of
these extra packets, proportional to how bad the connection is.
Lower this to reduce warping on players' machines (but possibly
hurt your framerate), or raise it to improve your framerate (but
possibly increase warping on players' machines).
Remove these from
the INI to restore them to the default values.

Bailouts: You will now free-fall for a period of time before
your chute deploys, though it will still deploy automatically.
Depending on the plane's orientation and speed when you bail
out, there is also a chance you may hit the tail of the plain
during egress, injuring yourself and delaying the opening of the
chute or even destroying it (or your capability to pull the
ripcord). Ideally you should be as slow (under 200-250 mph) and
as level as possible, and in any case at least a couple thousand
feet above ground before you attempt to bail out.
(Gear-up landing): You can now more easily survive a gear-up
landing. You will still take damage as you slide on the ground,
though, so try to be as slow and level as possible when you hit.
Combat Flaps: The
P-51 and P-38 are now equipped with combat flaps that you can
deploy at speeds up to 350-425mph, using the same key as the
regular flaps (F key). For all other aircraft, make sure you
retract your flaps above 250mph, or they may be damaged.
Flaps can no
longer be deployed at high speed. Exceptions are P-38 and P-51,
which are equipped with combat flaps that can be deployed at
speeds up to 350 mph IAS (P-38) or 425 mph IAS (P-51).
Non-combat flaps will suffer damage if they are not retracted
above 250 mph IAS.
Leading-edge Slats are added to Bf.109, Bf.110, and Me.262,
making them slightly less prone to enter accelerated stall.
autopilot mode is added. This function (SHIFT-A by default) will
maintain current altitude, heading and speed. The original

modeled more realistically. Depending on the aircraft's
orientation, speed and G-forces (level and slow is best), there
is a chance for parachute failure, or for various levels of
injury (hitting the aircraft) during egress. Once the parachute
deploys successfully, the game will continue, so you can use F9
or F12 to toggle between different aircraft and watch the rest
of the mission unfold. When you are finished, press Escape to

the Western Front, is removed.
Problem with the
artificial horizon in Spitfire virtual cockpit is fixed.
Cockpit lamp in
static cockpit now works properly when running the game in GLIDE
"flickering" on certain video cards is fixed in general.
Higher Screen Resolution (Unsupported)
EAW now recognizes
higher resolution settings in the EAW.INI file, specifically the
"Width=" and "Height=" settings. Your video card needs to have
enough frame buffer memory to support any new settings, otherwise
you will get an error message when trying to fly a mission. If this
happens, you can always restore the settings to the default 640x480.
Some settings you may
wish to try are 800x600 (many video accelerator cards should support
this--also try D3D mode if you can't get it to work in Glide),
1024x768 (higher-performance boards, or dual Voodoo II's, for
example), or 1280x1024. If you get the error message, try the next
The viewing area will
not be the same as it is in 640x480, depending on the resolution
setting. 800x600 mode will have slightly more viewing area, while
1024x768 mode will show slightly less.

still load as before.

settings further, like 1600x1200 or beyond, the edges of some views
may not render correctly (stray triangles), plus the "fisheye lens"
effect becomes more pronounced. For this reason you should stick to
1280x1024 or probably 1024x768 for the best results.
The main benefit, of
course, is a sharper resolution and better ability to see targets at
further distances, which many people prefer and requested. It is an
unsupported enhancement because not all video cards support it, and
EAW really wasn't designed for those modes, but it is an interesting
Bailout, Landing or Ditching: If you are still alive in a
regular mission, you will be asked if you wish to exit. If you
choose No, you can use the various external view keys (like F9
or F12) to jump around and watch the other aircraft in action as
the mission continues without you. When you are finished, press
Esc to exit as usual.
A bug in music

screen, is fixed.

the wing leveler, which will hold your current altitude, speed

slow to hold your altitude), the wing leveler may adjust the
speed or altitude slightly to try to achieve stability. You may
use this command in both single and multiplayer mode.
