(adsbygoogle = window.adsbygoogle || []).push({}); Can someone help me with unlocking the Mortal Kombat 9 bosses? I have a cfw 3.55 ps3. But, whenever I follow the steps of a tutorial on how to do this, I can't install the "Bosses_fix_pkg." for some odd reason. So can someone give me a more detailed tutorial on how to do this? I'll rep you.
