I finally got dismemberment working thanks to Aiden Silver's post. I actually changed my target around a bit so that it looks like this now:
"C:\Program Files\LucasArts\Star Wars Jedi Knight Jedi Academy\GameData\jasp.exe" +helpusobi 1 +set g_sabermorerealistic 2
Now I am hoping I can turn the probability for dismemberment down some. It gets old seeing EVERY enemy get sliced to ribbons. I want some variety.
I've seen some posts that talk about codes such as g_dismember, g_dismembermentProbabilities, or g_dismemberProbabilities. I've tried a bunch of combinations without any changes that I could notice.
Anyone know the correct code? I am only interested in single player, and I would like to be able to make so that dismemberment happens only, say, 10-20 % of the time.
