Google "Brute Force Save Editor" for the PS3. Learn how to use a hex editor (or google the hex values for coins in Ni No Kuni) and you can use your own save for this.
False brute force save editor requires a cfw ps3 or ways to get your keys off your ps3. people are using their own saves. They are not loosing anything just gaining money. This requires one thing them to mail me their save. I'll send that same save back but with max gold and coins, and not everyone knows how to work a hex editor and had rather have someone do it for them which is what I am doing but I'm not charging for it
Actually it's not false. Would you like me to send you some links to prove so? It's easily read online anyway, just google it. It decrypts the save for custom editing, then re-encrypts it to be put back into your ps3.
Even hex editing is easy if you can find the right values online. If others post about it you don't need to know anything other than how to search for the variables.
I don't have anything against what you're doing, it's great that you are doing that for free, but would help others that want to do it for themselves to show them where to go.
