Ps3 minecraft, Can't use usb saves?

I read its easy to get saved games from net, with PS3 folder on usb drive. I have tried it step by step *there's not many it seems* but to no avail. I can see game on usb drive from ps3 menu and I copy it but It won't loaded on minecraft itself with my other saves. Did they patch this? I just can't find answer

Yeah, they patched it a long time ago. The PS3 can't use other saves as the saves are locked to the original profile used. If you try to use another save, it won't allow it. This is to prevent cheating. You'll just have to make your own save on your own profile.
