KOTOR is a fun, Star Wars game that I've been playing through recently. As an example of virtue ethics, the game has your character moving between the light side and dark side of the force as you make choices. One part of the game requires you to save an alien who is being attacked by a couple of drunk humans -- do you let them kill the alien, or save the alien and then demand a reward, or do you refuse the reward and walk away happy? Each choice has a different effect on your character.
Of course, each choice also carries other outcomes -- some get you more XP and some more money. Where do your priorities lie? Or how do you feel like playing the game?
Anyway, I felt like playing the game quickly and without messing around with some of the stupid ways to earn money. So I saved my game a couple times and ran a filecompare on the different versions of my saved game files.
MONEY CHEAT
If you open SAVEGAME.sav in whatever directory corresponds to the save game you wish to edit, type FFFF at offset 0x00000d18 and 19. That gives you 65k credits. Should be enough to get you any grenades and health packs you might need.
The nice thing about this cheat is that it doesn't trigger the "cheat used" flag that otherwise is activated. (If you use any of the in-game cheats other sites may talk about.)
The other nice thing about this cheat is that I worked it out myself, so it counts as a meta-cheat. Changing the rules of the game by taking advantage of weaknesses in the architecture. My favorite way to cheat.
