Ok, collect the Jedi Holocrons, at least 125 or more. Ok, go to the Holocron Viewer at Rouge Shadow, When you see the last coloumn, open the Gallery photos, you will see Cheat Codes at the lower right corner of the photos. There! now you won't go to the internet finding codes everytime. Tip: Cheat Codes won't show up in 1st time, open the photo again to see it.
