NP man. I love testing new stuff out for X10. I have had tons of luck with most of model packs working in X10. Most of the character will work by adding the darkai.fpi script for the main under the properties. It is a ton of fun and a killer pack. I have also tested some stuff from the store and also got most of the stuff working. The best thing to do is after you install the packs lets say to FPSC, just copy and past the folder in the same path in X10. Than open X10 and test each of the entities in a test map. You will notice that most of the items will work while a few may not. Than you will know which ones you can use while building you real level.
Hope this helps and happy building.
