Fake Level Up is a glitch in the original KotOR game, for XBox, that allowed you to create a Jedi with as many feats, skills and Force powers as you wanted. A variation on the glitch allowed you to transform normally non-Jedi characters into Jedi as well.
http://www.rightstep.org/kotor tells you how. I haven't updated the page to my new stylesheet though, so it isn't very pretty at the moment.
Ah... a window of opportunity.

does it only work on the Xbox or does it work on the PC too
