like in title what file do i have to transfer where it is? and transfer to where

if you have beaten the first game there should be a file that says Data Crystal copy that file and transfer it to the same spot you found it but in Gutter Trash if you did it right the scene you unlock plays out the second time you pass through the city before talking to Scratch the second time
