How do you use the 3 klassic fatalities in MK9?????

So I downloaded the MK 9 classic skins off X-box live, and they work, but the the three klassic fatalities don't show up. how do I use them???

You have to input the combination yourself to unlock them.  I can't recall the exact combinations myself, but I'll update this post when I find them.
 
EDIT: Can't remember distances except for Sub-Zero, but here they are
Scorpion's Toasty: Down, Up, Up, Triangle (PS3) or Y (360)
Reptile: Back, Back, Forward, Down, Block
Sub-Zero Head Rip: Be close and hit Forward Down Forward Triangle or Y

Reptiles and Sub-Zeros klassic fatalties don't work for me. I'm not on xbox 360 live but just normal xbox 360. Do I need to enter some kinda code or something?

u must to use the klassic kostumes to do the fatalities in kombat
