Buy The PS1 version of MK3, and put it in a CD player. You'll get background music, names, the DUHDUHDUUUUUH sound of the fatalities, the background music of animalities, and a bunch of other stuff... I'm going to rip them to my computer. BTW, I think you have to skip Track 1, that's game data.
EDIT: I just imported them to my Comp. I've almost finished naming them all, since my computer doesn't recognize the music, I can't remember a couple, but I'm ogint to play MK3 to try and figure it out, isn't that a good excuse? Wait, Simpsons is on, I'll do it later. See ya!
EDIT 2: Is there any way I can send all of these files to you? There're about 60 sounds. I can't compress it, my computer can't. Can I upload a whole folder? Please help me out here.
