EDuke32 Parameters

Usage: eduke32 [files] [options]
Example: eduke32 nukeland.map -usecwd -cfg myconfig.cfg

Files can be of types {grp | zip | pk3 | pk4 | map | con | def | rts}.

  • Specifying a {grp|zip|pk3|pk4} file is equivalent to using the -g parameter.
  • If a .map file is specified, it is immediately loaded and launched as a usermap (equivalent to -map).
  • If a .con file is specified, it replaces GAME.CON (equivalent to -x).
  • If a .def file is specified, it is used as the main DEF file (equivalent to -h).
  • If a .rts file is specified, it is used as the main RTS soundbank (equivalent to -rts).

Removed Parameters

The following parameters used to exist, but are no longer referenced in current eduke32 revisions.

Parameter Description Notes

-f# Send fewer packets in multiplayer (1, 2, 4) (deprecated)
-i# Use networking mode (1/0)
-nD Dump default gamevars to gamevars.txt

Mapster32 Parameters

Usage: mapster32 [files] [options]
Example: mapster32 nukeland.map -usecwd -cfg myconfig.cfg

Files can be of types {grp | zip | map | con | def}.

  • Specifying a {grp|zip} file is equivalent to using the -j parameter.
  • If a .map file is specified, it is directly opened in the editor.
  • If a .con file is specified, it is used as the main resource for M32 CON commands.
  • If a .def file is specified, it is used as the main DEF script.

The set of parameters for mapster32 has some overlap with eduke32. Below is the complete list.
