Game Genies were the biggest con for ages, they would sell a disc of saves that is it, and of course you couldn't use them without having to lose your achievement entitlements.
Worst part was the fact they called them cheats in ads.
I see, but that doesn't seem to be the case in this situation.
I might be wrong though.
Not now since everyone else did the hardwork of decrypting everything for them.
Sony won't be liking them either since they are giving people a chance to get easy achievements, etc.
Actually, i read somewhere that using cheats Disables all or most achievements, so i guess Sony shouldn't have a problem with it.
