Well I have a little buggy tool which converts those values easily but you have to do something by yourself. We can't just help you with everything so you got to figure things out by yourself and most of the times the hard way is the best way:P
But I don't have something which just says like owh this is the hp or this is the mp. you just need to convert the values to it's real value. (You might use the packetreader of the emulator and store the non parsed packet in a buffer and load it into the packetreader).
and then you have to rebuild the packet. check which things changed and I assume a lot xD an emulator isn't just something easy it's really hard to figure out what some values do and there isn't an universial packet converter which returns all the values with their description.
and ofcourse it's easier for me than for you but how do you think how I learned how to read packets ect? not by asking someone else to do it:P I spend a while on figuring out how you can read packets and once I knew those kind of things I just used the packet reader to read parsed packet.
