How do you cheat with Star Wars knights of the old republic II

Go to the games files - if you're using a disc version this can be often located at,
Computer > Local Disk (C:) > Program Files (x86) > LucasArts > Knights of the Old Republic II
If you're using steam, it can be found at,
Computer > Local Disk (C:) > Program Files (x86) > Steam > SteamApps > common > Knights of the Old Republic II
Then scroll down and select 'swkotor2'.ini Go over to [Game Options] and hit enter, then type down the following,
EnableCheats=1 (If you want to disable cheats, just replace the '1' with a '0')
Now, restart the game if you have it open. From there, you have cheats enabled. For a list of commands, go to this page located on IGN,

Also, remember in order to enter a command you must hit ~ and type it down and click enter, remember to type it exactly or you'll have to type it all over again - backspace does not apply so you'll just have to click enter and try again to restart. Remember, the command window is not visible in KOTOR II for some reason. I hope you found this answer helpful, good luck in your adventures in Star Wars: Knights of the Old Republic II: the Sith Lords!
