Dude, people are not online 24/7, and, no one seems to have been able to find the sounds. If you google it and find nothing, chances are, no one else is gonna be able to google it and find anything, either.
Please don't double post.
If someone ends up somehow finding it for you, I am sure they will post it.
I looked before I posted in the thread. I didn't find any, which is why no one else, including you, can't. I found sounds for other MK games, but, none for 9.
