Don't get me wrong but aren't you working on the emulator? I mean such things are just routine in creating an emulator aren't they? I guess that the hardest part of an emulator is the logic to handle a lot of users at the same time and get everything working correctly.
But I will take a look at that packet and update my emulator too see if the same happens to me.
btw which packet is this exactly. just a opcode would be fine. from your story i'm getting the idea that this is the characterdata packet or the patch packet but I don't know one you exactly mean so an opcode would be nice
