Any text editor will do
Editing SND files
Easy as stepping on an Ewok!
STEP 1:
Just open the desired .snd file in a text editor like Notepad, Wordpad or Write.
(I usually use the "ky.snd" as a template).

STEP 2:
Notice that for each "events" like walking, swimming, hurt, etc
there is a name for a .wav file.
STEP 3:
All you need to do is change the name of that Wav to another.
If you can't guess which particular sound the name refers to
just use an extractor like "ConMan" or GobExplorer" to extract
that particular Wav file.

STEP 4:
You don't have to stick to standards. Be creative!
Adding new .wav files
Easy as skinning an Ewok!
STEP 1:
Simply create a new directory called "sound"
inside the "ressource" directory in JK or MotS.
STEP 2:
Then put the desired .wav in it
STEP 3:
Don't forget to add them in a .snd file if you
wish to use those new sounds in the game.
Using the new sound files in Multiplay
Everyone must have a copy of your new .wav file
if they are to hear them.
Adding the new .snd file to the Models.dat file
Here's what you have to do on order to use your new SND file.
STEP 1:
Simply create a new directory called "misc"
inside the "ressource" directory in JK or MotS.
STEP 2:
Then put your "Models.dat" file in it. This is the file that indicates
to the game engine which sound file to give to which character.
STEP 3:
Open the "Models.dat" file in a text editor.
Simply add another line at the end or change one of the existing line.
If you just want to change a sound file, all you need to do is substitute the
name for the particular .snd file you want to change to.


STEP 4:
Then create another directory called "snd"
inside the "misc" directory in JK or MotS
and just put your custom .snd file in it.
That' all!
Models.dat in MotS
The "Models.dat" file in MotS is different than the one in JK.
Aside from the sound and characters hierarchy, it is also here that
you will asign the "MotS personality" to your new character

The number before the character's name
corresponds to his / her / it's personality.
1= Jedi
2=Bounty Hunter
3=Scout
4=Soldier
0=Team character (won't appear in menu)*
*this last one is optional

Important:
The "numModels" should ALWAYS be updated
everytime you add a new character in JK (and MotS)
or the game will crash!
