cxsjmiaa - one shot kills the enemy and yourself.
fjjcuaac - cluster missiles for the N-1
gpayqwaj - unlocks all main levels and Secrets of the Trade Federation
jobxxfai - art gallery
abvuseay - heat seeking missiles for the N-1
jhgnrgas - bonus mission with Darth Maul and the Sith infiltrator
noskilz! - infinite lives

I know that these codes work, I've tried them out myself.

But watch out, playing with infinite lives you won't get a medaal. Because you need to save lives to get medals.

I've got codes which I don't know of the are for pc or nintendo.
Can anyone help me who's got a nintendo?

hey thanks, I edited them into a sticky in the passcodes forum. :)

Going to copy that sticky and post it in here now. :)
