I know its a dead thread but meh
Thankyou Ten-96 for that tip. i had troubles getting KSE to work on my xbox save and doing what you said got it to work.
By the way you don't have to have the pc version installed. i got KSE to work just by adding empty folders in the right place and then placing the save into it (C:\Program Files\LucasArts\SWKotOR2\saves). To think that i have wasted all this time modding my original xbox when i could've been playing it on my 360 this whole time! Ah data transfer kit, thankyou microsoft for giving us the means to mod your console while upgrading my HDD
Many kudos to you
