Would it be illegal if I were to take a music file from Baldur's Gate, let's say, and use it in Kotor 1?
I thought it was only illegal if you released it to the public? Because I have some music from Mass Effect 2's DLCs that I use in KOTOR that I downloaded from some site.
Well duh. Its only illegal to release it. Nobody cares what you do to the files on your own computer as long as you didn't get em illegally.
