I know very little about finding files in the computer, so I'll need detailed help, so I don't ruin anything on my PC
only reason I wanna enable cheats is because I have literally beaten this game (legit) more than a dozen times.....probably approaching 2 dozen, so I feel like playing an "overkill" save for the hell of it
^I cheats may be disabled on games you boot through Steam. I bought the Best of PC several years ago, and have successfully used cheats on both KOTOR and Jedi Outcast. For a while, I had Steam set up to include non-Steam games on my computer in my library so I could boot them right from Steam, but I found that the cheats didn't work anymore for Jedi Outcast. I could boot the program from the start menu and they would work, though. I never tried cheats on KOTOR booting through Steam, but I think Steam may somehow disable cheats altogether.
That said, if you bought the game from Steam, I think it is very likely cheats are disabled on it.
