I'm trying to just walk through the process on how ShowEQ just decodes (not unencrypts) the packets, as I'm going to try and write something that will decrypt the P99 game stream with the xor key. I just need to understand how I can debug this with live/recorded game data to test... I have never debugged a running program before until now. I think that's why it's been so difficult getting to this point as it's all new to me. But I'm definitely learning things daily. As a side quest, I'm trying to get my Dad to get his old PCs out of storage to try and find old ShowEQ files. Maybe he's got an old copy with the decryption stuff in it (I know it was a little different, but anything would help).
