erm it sounds like you really dont know what you're doing..
dll's are executable files, same as exe's to view them to edit you'll need a hex editor, to view them and understand what they're doing you'll need a disassembler (and knowledge of assembly)and you cant magically turn on force feedback on a game that mightnt actually support it in the first place, it definately wont be as simple as copying a few tiles over, that much i can assure you...
