Psn games

I don't want to sound like a pirate or anything, but say I don't have a psn account but I have some psn games and I am running Rogero cfw 4.30.

How would I go about installing back-ups of psn games that I have stored on my pc if I do not have a psn account.

I am talking about games like the psn versions of lumines and bomberman among others.

Thanks all.
