TB is at the moment the only way to play WWE'12 , it's basically The normal way to do it as would a 3.55 fix . Replace the Eboot and such . But if you have downloaded the TB fix and you see a few files . You open the first file using (open with winrar) you will see a PS3 Game folder , Extract that to the desktop and you will know what to over-write.
TB i invested in , mostly because of some games i wanted and it has paid for itself and then some , Just hope that Naruto Generations gets a fix soon now that it is out in japan and there are more than a few JPN releases (TB) so you never know.
This is my very first post , i hope i helped.
