TA at the command line
There are a few helpful command line switched that effect how TA operates.

You can either cut and paste the path into Start|Run, modify your TA shortcut or enter the path in DOS mode (The actual command line :D).
General command line extension X:\cavedog\totala\totala -##
General with client command line extension X:\cavedog\totala\totala -## -# -#
E.g. c:\cavedog\totala\totala -dw -N1:[222.222.222.22] -HMy_Game


General Switches
-w
Use the standard Windows multimedia interface for playing sounds instead of DirectSound.
-s
Disable the use of DirectSound if you do not have a sound card or the game crashes while trying to play sounds
-d
Places TA in windowed "debug" mode. Requires more CPU resources. Battle screen is set to size of resolution setting (no auto-stretching)
-c
Disables startup movie
-i filename.ini
The filename should first consist of a group, seems to only work with the group named totala, however its supposed to work with other groups as well.
