[REQUEST] An updated "How to hack a client"

[jumpnjahosofat]

I've searched the threads and it seems that all the how to threads are a bit outdated. I've still tried to do some of the ones that I did find but it didn't work out too well for me. I play on private servers and they tend to have their own clients so a client that works for PWI will not work for it. If there are any threads that tell how to do this a bit better or are a bit newer than some of the ones i have seen, please feel free to direct me to them. Otherwise, any suggestions on how to hack the client myself would be helpful. Thanks for your time!
