[1] INTRODUCTION
----------------
Hello all Doom fans of the world, here is the latest release of
Doom LEGACY project by Fab & Boris (we still didn't found a name
for our team, let's say it is 'Fab & Boris').
Well, if you are reading this you probably know by now that the
gods at IdSoftware have released the sources of the greatest game
on earth : Doom !!
Of course a lot of projects have started around the sources since
about January 1998, and Doom LEGACY is competing to be the best of
the choices!
We have always dreamed of Doom sources being released, and all the
features that we'd like to add. Since Doom1 was out we are fans
of deathmatching. Don't ask us why we like it more than Duke Nukem
or other clones, we like the atmosphere of Doom and its like that!
This new version of Doom is not commercial anymore, but you should
have the original Doom2 data (doom2.wad and other files), that comes
with the original Doom2 software.
If you have problems running this version or want more informations,
first: READ THE FAQ. If the FAQ doesn't help, mail us at:
legacy@frag.com
We hope that this new version brings you a lot of enjoyment,
especially for the deathmatch fans out there.
Have much fun!!
[1-1]: What's New
=================
Please see 'whatsnew.txt'
[1-2]: What's coming
====================
We have planned other features. See our site:
http://www.frag.com/doomlegacy
-------------------------------
[2] INSTALLATION OF DOOM LEGACY
-------------------------------
Doom Legacy should be installed in the directory where you have
your original Doom, Doom2, or Ultimate Doom installed.
It won't replace any existing file from the original Doom.
Doom Legacy will run in the mode of the original Doom version
where it is installed. That is, if you have installed Legacy in
Ultimate Doom directory, it will act like Ultimate Doom, pro-
viding 4 episodes, and no super shotgun.
[2-1]: Setting up the game
==========================
Legacy doesn't use SETUP.EXE anymore, it uses 'config.cfg' now.
There won't be anymore problems with the original Doom config
file 'default.cfg' : it will never be changed.
To configure your original Doom, use SETUP.EXE.
[2-2]: Setting up the controls
==============================
Setting up the controls, mouse and joystick, video mode is done
while in the game, using the main game menus : Setup Controls,
Video Options, Game Options. You can change all game settings
at any time during the game, forget about SETUP.EXE !!
The mouse will be activated as default, to disable it, change
the 'use_mouse' variable in the console (see console.txt)
The joystick will not be used as default, set the 'use_joystick'
variable at the console, to one of the joystick types supported
by Legacy (up to 6button joysticks + hat, see console.txt)
[2-3]: Setting up the sound
===========================
The sound and music card is auto-detected at the game startup.
If you don't get any sound in Legacy, check that the BLASTER
variable is set. Type 'set' at the dos prompt (or dosbox under
Windows) : do you see a line like 'BLASTER=A220 I5 D1 ...' ?
If not, run the installation of your soundcard for Dos mode,
it will usually modify your autoexec.bat so that the BLASTER
variable will be set. See the FAQ.TXT for more.
If the BLASTER variable is set, but you still don't hear any
sounds, or the sounds are not right, then edit the SOUND.CFG
file, and manually set your type of soundcard, see there for
more.
[2-4]: Tuning up the mouse speed
================================
The main Options menu still limit the mouse sensitivity value
to a 'normal range', but you can now increase this value even
more using the console variables 'mousesens' and 'mlooksens'.
If you used to edit default.cfg for the mouse sensitivity,
forget about it and use the console!
[2-5]: the Setup Controls menu
==============================
You don't need to use the SETUP.EXE now, there's that cool
'Setup Controls' menu.
Using this menu is pretty straight forward, you can bind actions
to one or two keys, like in Quake.
A single key can be set to multiple actions, eg: go backward and
'use' at the same time.
To CLEAR the keys attached to a control, use the BACKSPACE key.
To setup the DOUBLE CLICK for mouse/joystick buttons : enter the
click one time, so that it displays, eg: 'MOUSEBUTTON1'. Then
re-enter the click a second time, and it will transform into a
dbl-click, eg: 'MOUSEBUTTON1' will become 'DOUBLEMOUSE1'.
You can use double-clicks for any joystick/mouse button, and you
can even attach any action to it, eg: strafe left/right with mouse
buttons, it works. Just enter the button two times like said before.
-----------------------------
[3] ADDITIONS TO DEATHMATCHES
-----------------------------
[3-1]: Shooting up and down
===========================
There's nothing changed, except of course a totally new
deathmatch experience.
About the BFG : the bfg ball can be fired up or down, but
the invisible rays that spray from you are totally independent of
your aiming. The invisible BFG rays have always 'autoaim', they're
not dependent of your aim. Let's be clear: apart from being able
to shoot the BIG BFG BALL up or down, the side-effect of the BFG
is like before.
[3-2]: Auto aim toggle
======================
We wanted to keep the compatibility with the older Doom gameplay,
but we needed also to go forward and bring some more depth to the
deathmatches. On of these steps, is going for the manual-aiming.
You may feel like it's unbalanced if some people use the autoaim,
as they don't have to do the effort of aiming right, and others
don't use it and do their best to aim up and down right...
NEW since Legacy v1.2 : you can disable autoaiming, that is, impose
manual aim to all players in a network game, use with caution!!
[3-3]: Weapon changes
=====================
We didn't dare of course change the existing weapons functionality!
You may appreciate however, the fact that you can remap every
weapon to any key, in the Setup Controls menu. Since you can map two
keys per 'control', you can keep the original keys '1'-'8' for the
weapons, and add a shortcut to your preferred ones. eg: '5' and 'r'
for rockets...
New weapons are planned in the future releases: probably a grenade
nearly like Quake1 ones. Maybe an addon for the rocket launcher to
transform it into a 'guided rockets' launcher... like the Revenant's
fireballs.

[4] THE CONSOLE
---------------
Check 'console.txt' documentation for more about the console.
------------------------------
[5] NETWORK GAME (MULTIPLAYER)
------------------------------
IMPORTANT NOTE!
NEW, since Legacy v1.2, the network part of Doom has been totally
rewritten. It now uses a better transfer method for the packets,
(which is usually faster), and also implements a basic
Client/Server model, where some critical game options are
changeable only by the server in multiplayer games.
Since the network communication is faster, we have upped
the number of players to 32 !!
[5-1]: Quick-start of a 5-32 players network game
=================================================
To start a game with more than 4 players, we recommend using
Doomatic. Doomatic is a utility written by us before the source
release, we wanted to create a deathmatch launcher with all the
features that we always needed.
It replaces IPXSETUP and DM. Just read the 'QUICK START' sec-
tion of DOOMATIC.TXT file to get started with Doomatic.
Since we've added more than 4 players support into Doom LEGACY,
we have modified DOOMATIC to allow starting games with up to
32 players.
Make sure that the map you use has enough deathmatch starts!
Search on internet Doom sites, there has been a number of wads
specifically made for the new Doom ports with more than 4 players.
Cooperative play with more than 8 players is still not sup-
ported, we don't know if it works. Deathmatch starts are
converted to player starts if there are not enough.
[5-2]: the new Client/Server model
==================================
The network code has been totally rewritten, here are the
main changes:
- Doom Legacy version 1.2 supports up to 32 players.
- The speed is now dependent from the Server. if the server looses
frames, that is: if it runs too slow, all the other players will
experience the slow down, or 'choppyness'.
Thus, make sure that the server's machine runs smooth, example:
a P100 running the game at 320X200 may be very smooth. while
a PII 300 at 1024x768 will slow down the network. Why? simply
because while the server is occupied drawing his screen, he can't
send or receive any packets, and thus the other players are slowed
down at the speed of the server (well, now it is possible that
a PII 300 is very smooth at 1024x768.. but you get the idea).
- The memory is very important so 16 Mb is a MINIMUM for a server.
Why? Because a server with not enough memory will often load
data from the disk, and this will probably slow down the game.
- Don't forget to put a very good disk cache, like 4 Mb or more.
A good disk cache will reduce the loading from the server, thus
reduce possible slow downs.
- The server can kick any player ouf of the game. The player will
be returned to the title screen.
- Consistancy failure now kicks only the player who was not
'up-to-date', but not the others.
- Parameters -left -right came back (using 3 screens for left,right
and front views).
- Most critical game variables are send to all the players when they
are changed by the server, and only the server can change them.
Examples are 'allowjump', and 'respawnitemtime'
- The new possibilities are barely demonstrated in Legacy v1.2 :
we can now make any console command work on the network, so there
are very good things ahead!
The new system is still compatible with IPXSETUP and SERSETUP, so you
can use these to play games up to 4 players.
To play with up to 32 players, use DOOMATIC.
Note that DOOMATIC was created by us long before the release of the
Doom sources, and it works with the orginal Doom, and with most
other ports, too. We didn't create DOOMATIC specifically for Legacy,
but we updated it so that it could start games with more than 4
players for Legacy.
[5-3]: Setting up the SERVER
============================
There is no interface for now.
The server is the player 0, which is the GREEN player in DOOMATIC.
Note that the GREEN player in Doomatic, is not necessarily Green
later in the game : the server can choose any color in the
Multiplayer menu. Legacy doesn't use the colors from Doomatic,
but will recognise the Green player of Doomatic as the server.
In other words, you can't choose who is the server using IPXSETUP.
We reassure you: this is a hack, and we will add a '-server'
parameter as soon as possible to determine explicitly the server.
The color you choose in Doomatic is useful for the original Doom
game only : it was a key feature of Doomatic, to choose the colour
you wanted to be instead of getting always the same color from
IPXSETUP. It became obsolete with Legacy, as you can choose your
color in the game itself.
The SERVER has more rights in the game, and no, it can't cheat.
It can change the game parameters like 'repspawnitem','respawn-
monsters', ect. and can Kick players. Therefore, choose the server
with attention.
NOTE that there is no 'dedicated' server for now, everybody in
a multiplayer game and even single player, is always a server
and a client at the same time. That is: in single player, you
can slow down yourself, when you loose frames, usually in the
higher resolutions, you will experience a small 'lag' like on
a 'choppy' multiplayer game.
See CONSOLE.TXT for more about the server & multiplayer commands.
[5-4]: the return of -left/-right
=================================
We have restored the -left and -right command-line parameters,
that allowed in the earlier versions of Doom, to play using
3 monitors: one for the front view, one for the left, and one
for the right.
Here is how it works:
Use DOOMATIC and create a game on the machine that will display
the 'front view'. Make sure it has the GREEN player color
(in Doomatic, not in Legacy). Set '-left' and '-right' in the
local parameters of Doomatic, for the other two machines.
That is : the 'left view' machine has '-left' in the local
parameters of Doomatic, the 'right view' machine has '-right'.
Join the game with the other two computers, and start the game.
This will work only for SINGLE player, but the player will have
a very wide view!
[5-5]: How to play with tcp/ip
==============================
While waiting for the native tcp/ip support, you can use an external
program that converts IPX packets in TCP/IP packets like Kali and
others. (don't e-mail us about that we have never tried).
You want to know some things : you need a good ping value, perfect
is <30, more than this will be very unplayable, because there is not,
for the moment, code to reduce the latency between command entered
at keyboard and command execution.
In other words, Doom Legacy doesn't use 'interpolation' to make
you believe like the game is 'smooth' when it is not in reality.
We have heard that ppp conection (internet modem user) has a
minimum ping value of 100 to 200...
If you have played Doom Legacy v1.2 on internet, please mail us!!
[5-6]: Playing Legacy over modem
================================
No, DOOMATIC, doesn't support modem play as today.
Note that SERSETUP of the original Doom still works with Legacy,
and can be used to play Legacy over the modem.
[5-7]: Network parameters
=========================
The following game parameters are changeable only by the SERVER,
using the console :
(they also work in single player since in single player you are
the server AND the client)
allowjump, allowautoaim,
respawnitem, respawnitemtime,
respawnmonsters, respawnmonstertime
Of course all the player parameters works in network :
name, color, autoaim, weaponpref, originalweaponswitch.
See CONSOLE.TXT for more about multiplayer commands.
------------------------
[6] COMMAND-LINE OPTIONS
------------------------
There's a new environment variable 'DOOMWADDIR' that you can set
to the path where the original Doom and LEGACY Doom wad files are.
This enable to run LEGACY from any place on your harddrive, by
default, LEGACY searches its wad files in "." dir (the current dir).
Here's the new parameters that you can use from the command prompt.
In DOOMATIC, you can add command-line options as a server in the
Server menu's Add Parameters, or in the Prefs menu 'Local parms'.
(the Local parms will be used only on your side, while the server
parms are sent to everybody)
Additional parameters info:
---------------------------
-dehacked <dehfile.deh> [dehfile.deh] [ect...]
DooM LEGACY supports the dehacked patches... of course its
now done a more subtle way : you just specify the dehacked
patch file at the command prompt, no need to patch the exe!
You can specify multiple .deh files, and they will all be
executed, on the order you have put them on the command line.
-mb <number>
If you run out of memory, or want more memory, this sets the
number of megabytes of mem to allocate at Doom startup.
The default is 10.
-width <xxx> -height <yyy>
If you like the pain, you can set the screen size at the
command line instead of using the new 'Video Mode' menu.
Doom LEGACY will switch to 320x200 if it can't find a
corresponding mode. So remember to load your Univbe or
equivalent for extra video modes.
The rest is like Doom2 original, all the standard parameters
are still functional.

use our modifications, please give credits where its due. Thanks.
The sources of our modifications are released for the general interest
and in the hope that our project will grow bigger with other people's
talents and ideas.
[7-5] Dehacked patch note
=========================
We don't check for the dehacked patch version, we added support for the
patches version 6, it should run ok with (not too) old patches.
If you have a problem with the version of the patch, try to convert it.
Just load the .deh file into a recent version of Dehacked (3.0),
and then save it again. It will then be saved as a text-file, that
Legacy will be able to use.
All text changes are supported, you can edit the .deh manually and
replace strings by larger strings than the original Doom, it works.
Sprite renaming works too, well, pretty anything :)
If you can't run your dehacked patch with Legacy, please mail us!

BELGIAN NOTE
------------
Yeeeeeeeeeehaaaaaaa! We BELGIANS are very very PROUD because our
greatest compatriots have launched twenty custard pies to Bill
Gates's face, and four of them have landed succesfully!!!
(beginning February 1998)
It's 'pastry' terrorism here in Belgium!
