"doom -devparm ".
If the "-devparm" parameter is not needed, the parameter will be marked with a plus (+). Most of these parameters can be mixed and matched to create different effects. For instance, typing "doom -devparm -wart 1 8 - record demo01 -respawn" would record a demo on episode one, level eight, with monster respawn. Lastly,
typing F1 during development mode will allow a 256 color screen capture in
PCX format.@ Used to read in a command line parm file

-wart Loads a PWAD named ExMy.wad+: Does not require the "-DEVPARM" parameter.++: If you have a network, try setting up a network game with three players.
The three terminals should have the parameters:
"doom -devparm -nodes 3 -left"
"doom -devparm -nodes 3"
"doom -devparm -nodes 3 -right"
Then, set up the left and right terminal monitors next to the middle
monitor, in a virtual-reality type configuration. When you turn your
head, you see the screen turned 90 degrees! This ONLY works with
versions 1.0, 1.1, 1.4, 1.5, and 1.6 of DOOM.+++: Must be used in conjunction with the "-WARP" parameter#: For the "- playdemo" and "-timedemo" options, if you give an LMP file name
of "demo#" (i.e. "demo3"), then that internal demo will be played if the
external LMP file is not found. For example, to play the internal 1.6
shareware demo #2 (multiplayer demo), type "doom -playdemo demo2".
Additionally, when using "-timedemo," the game will give you two
numbers after you quit to DOS, GAMETICS and REALTICS. To determine
the DOOM frame rate use the formula (GAMETICS/REALTICS) * 35.Note: DO NOT name your LMP demos ExMx.LMP, or they will *NOT* work.

yo erased it), you wil still get credit for both of them even though only
one will be shown in the space where both of them "are."
