Alright, I do this a lot so I may not be able to describe it very well.
Start Menu, My Computer, Your Main Hard Drive (C:\\), Documents And Settings, You, Local Settings, Temporary Internet Files
Once there, look for the file soon.swf and drag it to the desktop or another directory. If you don't regularily clean out your Temporary Internet Files (highly recommended) you may be in for quite a long search. But once you find it, you can watch the MK:D Flash offline.
Now, if you want to decompile it, you'll need to get a Flash decompiler. I recommend
this one If you need any more help, PM me.
Like I said, this isn't really necessary unless you think you'll find something I didn't.
