You've just got to know how to texture a character from scratch. First you have to import the .X model from the FPSC files, into your modeler (that has to be able to import .X format). In order to get Aiko into GameSpace/TrueSpace, I had to use Ultimate Unwrap 3D as a file converter, then save it as a .COB file (TrueSpace/GameSpace format). After that (as I believe they didn't give us the UV Maps) you have to redo the UV Map, then texture as normal. At least this is one way of doing it, someone else may have another, less time consuming way.
