all the offsets and stuff for hight stats and low stats are the normal stat offsets. all you have to do is convert them ToIn32. then convert the number to string it is hard to explaing so here is a code you can use for kills but all you have to do for like deaths and other stuff you just change the offset and then change the amount you want
byte[] bytes2 = BitConverter.GetBytes(Convert.ToInt32("number of kills you want here".ToString()));
PS3.SetMemory(0x26FCB70, bytes2);
see how the code has in it (Convert.ToInt32("number of kills you want here".ToString())); . that is the code wat converts te number to string and that is for kills all you have to do is change the offset... For Set level 55 all you do is the set level 55 coding
