I know this is a shot in the dark.... I was wondering if it would be possible to edit individual saber sounds in KOTOR 1 and 2, i.e. sith saber poweron. It may not be possible, but it would be interesting to hear all the red lightsabers power on like the ones the sith use in the movies.
The Ultimate Sound Mod gives a whole new feel to KOTOR 2, but I think it would be nice to have a little more variation.
