Hi all,

I was wondering if anyone knows something about Quazal software rendez-vous and Net-Z? Like how does it work. How are the packets made? etc...

I tried googling it but couldnt find anything except that it is now taken over by ubisoft.


Thanks

I have a couple of quickbms scripts about "quazal", maybe they are useful:

Amazing, thank you. I will try it. Do you happen to know something about the internals of quazal? Like do they use serialization or strings or just plain bytes

Hmmm neither of your scripts appear to work. I have attached the packet in case you which to look at it. And the log entry when you respond with a random packet in case you wish to see it:

Unfortunately I can't help you further.
Maybe that game uses a different key, don't know.

I just came across this: https://github.com/Kinnay/NintendoClients it uses the prudp protocol, like quazal. So I wanted to ask your opinion about it. Could it help with understanding the quazal rendez vous protocol?

Nintendo uses quazal too, for everything it seems. Very interesting
