    So well, I have followed the guide very carefully and Im at the step where you dump your copy of Persona 4 Golden. Mine is a physical copy and I cannot seem to extract it. I have moved the data.cpk onto my computer and I have used 2 or 3 different programs and have deleted and redumped maybe 5 or 6 times but I cannot extract it. I could extract the Japanese one of course.What am I doing wrong?

    We can't possibly know without more information.

    I bet you dumped an encrypted version of the CPK by mistake.
    Just make sure you follow all the steps carefully.

    Try opening the file in a hex editor and looking in it to see if it's really decrypted.
    I downloaded dumped data.cpk (US version of the game) and opened it in a hex editor.
    Here's what the beginning looks like:

    But definitely shouldn't go piracy websites, download a vpk from there, and get its cpk by extracting the vpk with 7zip or something if you never get it to work.
    Because that would be too easy. ;)
