LMP v1.0 - A DOOM Demo Conversion Utility


This is a simple menu based program that will allow a user to
convert recorded DOOM and DOOM2 demos (.LMP files) from one
version to another. The currently supported verions are
v1.666 - v2.0 for both DOOM and DOOM2. Though the program will
not recognize DOOM demos that are earlier than v1.666, it can
still convert many of them to the later versions (v1.2 demos
are NOT currently supported).

You should be aware that a demo will only play back properly
if it is done so in EXACTLY the same level that it was
recorded in. In many cases, id Software has made minor changes
to the original levels from one version to the next and this
prevents older demos from functioning on those levels. The 1.9
version of DOOM2 has minor changes in AT LEAST the first 3
levels and I'm sure that many of the others have changes. I'm
not aware of DOOM having so many changes, so the chances of
successfully converting a DOOM demo recorded in the original
levels is fairly high. Demos that have been recorded in custom
levels (PWADs), will convert with no problems.

To run the program, simply copy LMP10.EXE file to the directory
that contains your .LMP files and type:

LMP <filename.lmp>

When the program loads, the file name of the demo will be
displayed on the title bar and you'll see a status area just
below that. The status bar contains the following information:

 DEMO SIZE

  This is the size, in bytes, of the file. It really serves no
  purpose to have this displayed, but I had an empty spot that
  needed to be filled...

 VERSION

  This is the current version of the demo. v1.7 and v1.7a demos
  are displayed as the same because... well... they're the same.

 SKILL

  This shows the -SKILL setting that was used when the demo was
  recorded.

 PLAY MODE

  This covers Solo, DeathMatch, AltDeath (DeathMatch v2.0), and
  Cooperative modes.

 NO. OF PLAYERS

  That should be fairly obvious...

 VIEWED FROM

  This shows the player whos perspective you are viewing the demo
  from. This will be either Green, Indigo, Brown, or Red. Note
  that this only relates to color assignments during the time that
  the demo was recorded. When you view a demo, it will always be
  through the eyes of a Green player, but that does not necessarily
  mean that the Green player that you are watching was the Green
  player during the actual game... he could have been the Indigo
  player! The only way to tell, is to load the demo into LMP10
  and see which player is shown under this entry. Get it?

 MONSTERS

  This will tell you if there are any monsters in the demo or if
  it was recorded with the -NOMONSTERS parameter.

 RESPAWN

  If there are monsters in the demo, this will indicate whether
  they respawn after getting killed, via the -RESPAWN parameter.

 FAST

  This indicates whether the -FAST parameter was used. This
  parameter causes many of the monsters to move and fire at faster
  speeds.

Below the status area, there are several numerical options:

 # 1-5

  These are for changing the demo to another version.

 # 6

  This will start DOOM or DOOM2, which will automatically begin
  to play the currently loaded demo.

 # 7

  This will start DOOM or DOOM2 with a PWAD file and will then
  play back the demo in that PWAD. You will be prompted for the
  name of the PWAD. If you type the name of a non-existant file,
  you'll hear a beep and will then be able to retype it. The
  PWAD may be in any directory on your computer, just be sure to
  type the full path if it is not in the current directory.

If you wish to change the demo to the perspective of one of the
other players, you can use the + and - keys to cycle through the
available choices. The status area will be updated each time that
you make a change.

That's it! If you have any problems, comments, or suggestions,
e-mail me.
