Black ops Zombie DLC on skidrow or other crack?

Im looking for a way to play Black ops Zombie DLC´s with the Skidrow or other versions but i havent found a way does some one know how to play them? or is it impossible?

just go on youtube or a torrent website and type in "black ops with all dlc" there will be ones out there. i used to have skidrow version of black ops with all dlc but now i have them legit.
