Hacking Possible to make a private WFC server?

[benben1]

Would it be possible to make a WFC private server? As far as I know, the wii sends packets to the server and the server sends packets back to wii(s). If we packet sniff what packets are being sent from the server when so and so packet is sent from the wii, we could technically make our own WFC server, just like how all the other kinds of private servers are made(eg: runescape). We would also have to change the IP the wii connects to to our server to work but that would be pretty easy considering we can just change it in the game's iso or through Riivolution, or is it stored in a file on the wii?

Benefits of private server:
1. Private server
2. Make server side hacks
3. Host crazy tournaments
4. Do whatever you want without being banned from nintendo
5. Less lag

So with that being said, do you think this is possible?

Changing the IP is simple even for retail games/carts, simply set your DNS server in your internet connection to the local IP of your computer and run a DNS server on it that reports the values you want for nintendo's WFC stuff.

People have already done it for pokemon, there's a few GTS server softwares you can download, and there's a "send pkm files to retail carts" or something thread in the DS hacking section.

Yes I've heard of those, but I'm talking about SSBB or MKW servers.

This would be good to eliminate lag in games such as SSBB.

Yes that too.

Although technically possible, I don't think the whole WFC would be replaced, but possibly individual games will have private server software made at some point.

Monster Hunter Tri has it's own servers.

Re PC custom servers- remember many PC games like this tend to use what amounts to SQL queries (one of the reasons your world of warcraft third party jobbies may be missing the odd thing) and some even benefit from leaked backends as well as a measure of peering in many games (not as good as a leak but halfway there in many cases).

This differs for the wii which may well use full blown custom protocols, handshakes/authentication- lots of work does happen but not very often. IP address stuff is trivial as Rydian said (indeed if you look back at some of the early gamecube hacks it was this technique that was used).

I would look at pokemon but they amount to basic file downloads give or take a bit of customisation. Proper dynamic games are something else entirely. Packet sniffing might not be that useful either- most of these games are encrypted nice and good and while we own the wii it is not a nice hack to pull off (mitm or repeat/chosen key would be better than post game decryption as it gives you the replay option but anything is good).

On the other hand they could just be (or could boil down to be) character movement and action packets with a server side score and looking at the game binary could allow for recreation of necessary data.

I agree it has many benefits but most hackers of that grade (the intersection between ASM grade hacker and web hacking is not as great as you might imagine- how many console hacker sites do you see with bad/simplistic web design or a simple wordpress arrangement?) would probably rather spend their time on something more "useful" (let us face facts even with stuff like xlink kai and other gaming oriented VPN not to mention it being orders of magnitude easier to use than this would probably be how much do you really hear about them- this would be somewhat niche compared).

Good points all around. If I were a dev, I wouldn't reinvent the wheel -- I'd use an existing protocol/library for communications and only tweak it as necessary. Possible? Certainly. Likely to happen? Not until the public servers start to go down due to age and there's a real demand for it. Until then, it will likely be a niche request like all of our other ideas, forever remaining untouched by the (relatively) few with the know-how to pull it off, because they have more interesting things to do.
