I made a little program to edit levels for FSA.
You can get it and all the other necessary tools here: Downloads and Guide.
Feedback would be appreciated from anyone who actually uses it to do any editing.;

Incidentally part of the program is a .arc(RARC file) packer which is nearly perfect in regard to producing the same output as an original .arc file, if anyone needed such a thing for another game?
Obligatory picture:
