Ah yes, the fine art of hacking a Sith Warrior to pieces with a lightsaber.  What could be more fun?
So far I only have a few Star Wars computer games:  Episode I, Jedi Outcast, and Force Commander.  Still, I've got just about every cheat for each of those games (plus some extras that aren't even cheats!).
Star Wars Episode 1: The Phantom Menace.
cheats
Hit Backspace to get the menu on the screen, then type one of the following:

Cheat
                          effect
give me life      get full health

i like to cheat     get all weapons, full ammo and full life
iamobi         play as obi-wan

iamquigon
    play as qui-gon    

iamqueen      play as amidala   

iampanaka      play as panaka    

perfection      either give you autofire/attack or makes your forcepush kill people, im not sure

drop a beat      your character gets high!!    (screen gets all wavy like)

NOTE: Cheat too much and the game won't you cheat anymore.
There are some other codes, of which i fail to see the point.  But if you care, check them out here
Jedi Knight II: Jedi Outcast
Cheats (single player)
First press shift and ~ to get the menu, then type devmapall to allow cheats.  Press shift and ~ to put the menu away  You can, at any time, put the menu away/take it out, but it's best to do it during a game after it loads and the cinamatic is over.

give force     give full force bar
give inventory give full inventory
give ammo     give full ammo
