well people have been posting many filters that change cables, Cd's, ect....
into rares. i have made a tutorial telling you how to make one. I am not doing this so more people will post, im doing it so people can make their own instead of asking for some one to make it for them.
For those too lazy to read the tutorial you can just download the filters I made, I went through and checked every filter to make sure they worked.
If you still cannot figure it out pm me and i will help you out.
