There are three of these save sets on this website, they are all the same. They all work. What is missing from the notes is that you need to take your existing save and config files and copy and replace the files from the save sets - the save set and config set files don't have the PARAM.SFO file, which you will obtain from your own save (this can be a save from right at the start of the game).

I don't know if you need to resign the saves but I do that anyway and they work perfectly.
