It's on page 1, a post by Pescado :
"If you decrapify objects, you must decrapify all of your SAVED GAMES (.nhd & .packages in your .sims3), PRESETS (userPresets.package), and LIBRARY."

I'm trying to understand how to install this, I read the txt file and it mentions a framework. Do I need to have this framework installed in order for this to work?
Also if I copy these files to my \My Documents\Electronic Arts\The Sims 3\DCCache folder will they replace my current files?  Does that mean I will lose all the other .sim3pack cc that I already have installed?

thanks
