I've seen this question asked a dozen times, and every time its answered by not being answered, or with vague responses of people that don't really know but are guessing.
Where he apparently shows you how to do it, but its not a great guide. The identify files hes talking about are empty, and i'm not sure if its an old guide or if they're supposed to be or what.
i tried the method in the other thread. opened the identify.dis which is empty, and just copy pasted them in and saved. worked like a charm. its stashing leggies unid now, havent dropped any set yet, but i added those lines too
