Instructions:
-First all you should install the DEMO of FIFA 12 PKG in the console.
-After opening the Multiman or file manager.
-You are looking for the folder of the DEMO of FIFA 12, NPEB90357
-Login to the USRDIR folder.
-Now on the other side of the screen you should find your FIFA 12 Original backup and enter USRDIR.
-Now, you must replace all the less the EBOOT files.BIN and the other fifazf.self, if you now do not work. Not replace the DATA folder.
-Now sales to the XMB and you run the DEMO, but there already has all the files in the backup.
-To play!.

Apparently, the game freezes after each match and you have to reset it to continue. I would assume that the save function is working, otherwise, it's useless unless you just play matches with your friends in the same room.
