If you do a google search for "kotor 2 save game editor" you won't need a trainer. Not entirely sure they'll be compatible with the re-release, but I urge you to try it & post your results. Will be educational for anyone playing the re-release. I wasn't even aware this was a thing, I've played KOTOR2 at least 4 times since whenever it came out. Played it before KOTOR 1 even. (so I'm thinking very early 2k or '99, was in Korea till '99)
Despite Bioware making 1 & Obsidian making 2, the file, format & everything else is compatible, there's an editor that does both original releases of the games even. "kse_333".
Please try it out & post your results. I'd love to play an updated version of one of the best RPG's ever.
The save game editor is much more versatile than any trainer. IDK, I think there's even console commands for that game, god mode & whatnot.
