Wifi in Brawl?

That's not because of you. Most people, when see this thread, would think that Wi-Fi support is implemented. I'm just posting what we have at the moment. Don't take it too seriously

There was a topic by a member of the smash boards here the other day, apparatly they are working on hacking Brawl's wi-fi so they can get lagfree matches (on the real wii), and they wanted to cooperate with the devs I think... but the devs seems busy with other stuff at the moment.

Ok, thx for clearing that up.

Since Wifi on the real Wii is implemented high level (indeed, it's quite impossible to touch the wifi dongle on the low level, even though we have drivers for that chipset freely available) it should just be a matter of hooking the appropriate IOS calls and feeding them out through the Windows network. The issue does come, however, with the creation of friend codes. Theoretically, if you rip your own save file from your Wii, it would use the stored friend code from there and work just fine I would think. However, if it needs the console ID of your Wii to work, you would either need some way to grab that and tell it to Dolphin (it's probably in my NAND dump somewhere now that I think about it) or some way to spoof it in a random way.

I don't *think* the gameID thing is valid, as there's certainly nothing wrong with using someone else's disc for Brawl on your save file or vice versa. I do this at my house all the time since we have 2 Wii and 2 copies of Brawl, and I actually want to say the save file was created on both Wii using the same disc. Different friend codes of course.

If it were *me* designing ninty's Brawl server, I'd set it up so that upon first connect, the server just assigned you a random unique friend code. Save files for Wii games can't (normally) be copied between systems anyway, so the server can semi-reliably assume that the friend code it gives out once will stay with just one Wii. I'd imagine it wouldn't be hard for them to do simple checks to see if multiple copies of the same friend code were on at the same time though, and to be honest, I'm not entirely certain what information gets passed back and forth to the servers anyway when its giving you a friend code or logging you on. It would be fun to look into.

I'm starting to sound scary here. Next thing you know, I'll be looking through the source code and figuring out this "wifi" thing. Right after I learn how to go days without sleep that is.

Edit: Yeah, that went well. Almost *nil* documentation on the IOS calls for working with the wifi dongle. That means reverse engineering the homebrew library... and then hoping that's enough to figure out what the Ninty one is supposed to be doing. More work than I can manage in a night.
