Nintendo WFC will shut down in May 2014

[tueidj]

Yes. Nintendo pushed the stupid friend codes system on developers, now they're removing the only means to validate them.

That really sucks

But applying simple common sense really should make it obvious; if you've got 2 copies of the same program being fed the same inputs but running at different speeds, they are in no way guaranteed to act the same. Otherwise go read the comments at the beginning of SystemTimers.cpp that explicitly states, "These update frequencies are determined by the passage of frames. So if a game runs slow, on a slow computer for example, these updates will occur less frequently." Hence a slow computer will have a coarser granularity timebase than a fast computer, even though the actual values may appear to stay in sync.

They occur less frequently in real time, not emulated time. Everything happens less frequently if it runs slower, obviously. If it worked the other way, you would introduce the problem you are describing. If you feed the same inputs to a game, it WILL act the same every single time. There hasn't been a single non-savestate related desync in movies for as long as i've been around.

It seems like it would be fairly simple (on the Wii at least) to provide our own CA certs and spoof our own servers. The files are right there on the NAND and if Dolphin behaves anything like IOS does, /dev/net/ssl uses those files directly.

And yeah, that second naswii.nintendowifi.net connection only seems to happen in Brawl. (Or at least it doesn't happen in Mario Kart Wii.) My guess it's used if games have download servers for stuff, since the servicetoken from it gets used in those requests.

[tueidj]

But I wasn't playing Brawl...

On the wii it's actually easier to just set a debug flag (in IOS memory) to disable host verification, combined with DNS spoofing to redirect *.nintendowifi.net. The certificates are not stored in separate files, they're embedded in IOS and patching them would be ugly.

Well like I said I've only tested two games total so far

[tueidj]

There's also an "acctcreate" action (used the first time a particular game goes online) for which there were some OSReport logs floating around somewhere on this forum (since it causes the 20115 error under Dolphin) but I can't find them now.

[mbc07]

Well, error 20115 should not occur anymore in 4.0-1019 and newer. The recent commit made by Parlane makes the MAC address being randomly generated once and then stored in Dolphin config

The plan is to generate it ONCE.

We don't want to support banned users. If Ninty ban someone for cheating on their servers then fair enough.

Fascinating how quickly the service going away changes people's attitudes.

I'll just leave this here. I guess that merge conflict really was too much for him.
