It's normal that the file size is the same as before. The patcher is modifying only some bytes but doesn't add or remove something. If you want to check if it is altered you need a binary comparison.
The filesize will have a noticeable difference if even a single byte is altered.Not in numbers but it will tell you that the file is bigger or whatever
If you can't wait you can do it yourself viewtopic.php?f=26&t=181
