The problem is even the "fake original file" must be present as a file within your GC folder already. So you still got to download a file to place in your, say, the ResSet folder.
If so you might as well download a KR version of the files since NA versions of those files (yea only the char zero 2 ain't there) aren't here yet. Just saying why it isn't possible for the program to replace what is not there.
Though on the side note suggestion, perhaps the program can include the files in there as a download?
