Is their any public source for War3 Source Decoding? I have been trying to implement it into my bot for a while now with no success. Also, is their any additional login packets needed for War3?
Perhaps you should post your research in addition to just asking the question to at least let a potential helper know you're actually trying? :-P
To my knowledge, the only publicly available method is to use BNLS (http://www.valhallalegends.com/yoni/BNLSProtocolSpec.txt).
