for their stats, all they did was hex edit the values client side. is pretty much useless since stats are stored server side. you can edit your client to always have 9k hp and 300tp with 999mil gil but it cross checks with server so it will still just use the actual values. only use i can see is for making fake screen shots w/o using photoshop (so they looks a lot more real)
