Well, that's impossible:
SQUARE ENIX and Nomura (<- ) Never really made an anti-piracy patch. Even the newer games don't have it. The culprit is the .prxs that are missing from the 5.50 OFW that are in 6.20 OFW, which the new games run on.
In order to make the games run, we need to make a new 5.50/6.XX CFW that have these .prxs. This method will be able to be run by regular people just like you who don't have all the special tools that we do.
We're also waiting on Team GEN to come up with something... We haven't heard from them yet.
Thanks you guys!
