If someone wants to reverse engineer the packet data for Xbox Live communication they had better intercept as much as they can before April while they can get a complete and accurate picture of what is needed to make the original Xbox work. I honestly don't think that the core of what is required would take an unreasonable amount of work. It is not a terribly complex service. You have a central login component, some bits about the user that are stored at the server including some account information and a friends list, a pretty simplistic messaging system, an equally simplistic voip component, for most games an also very simple master list feature, for some games a matchmaking component much of which may be library side, you have the p2p protocol that is used for a lot of games, and some other common stuff. The most complicated aspects of it are going to be replicating the handshaking between the Xbox and the service which can be potentially minimized since the consoles are all modded ones anyway (although it could be considered that there might be a way to do this so that name resolution changes are done apart from the console so that an unmodded console could participate but that would create a lot more pain.) So there will be some difficulty in cracking encryption and bypassing security (although MS has shown that they were pretty inept at developing reliable security or encryption schemes for the original Xbox) but the core of the service is made up of common components that are implemented in open-source applications up and down the internet lane.
The greater risk here is the potential for legal action on the part of MS. But I think that there could be a potential argument that MS stopped providing a core service for the original Xbox that was a large part of the products appeal and that the defendant simply stepped in to provide a replacement service. This sort of thing has happened a million times in the past. There are online games going way back that are playable online using something other than the original service provided. It has even been done with consoles as you can play PSO on the Dreamcast to this very day and that is because people in the community stepped up and replaced the discontinued service. Of course the best way to be immune from any legal issues is to have the service running in a country that isn't likely to entertain any legal disputes... a safe haven of sorts.
The alternative is that Live on the original Xbox goes the way of Sega Channel. How many of you remember that? I do. It was awesome. It is forever gone.
pso days i help make that possible... "broomop" the best way to make this work is maybe removing the encryption totally for now or dumping it unencrypted so that you can at least make it easier to dump and make the server and then add your own crypt after.This post has been edited by Brooshop: Mar 2 2010, 05:10 AM
