Thanks V1 I fixed the icon and I found out paf.prx is indeed the one I want to edit, just I have trouble with it.
I loaded my paf.prx with Hex Workshop and loaded the HBK bookmarks, all fine just each address in the bookmarks have very strange values like for example 4.0 for Text alpha and something with -2.something.

So I thought the prx was scrambled yet if I apply a unscrambler to it all I get is a 9kb garbage prx so I'm really at a loss here...
