Error 52200 when connecting, disconnecting, then trying to connect again.

Might as well make this official. This is a big error and we're all quite puzzled what actually causes it. It has to be either in conntest, nas, profile or qr -- most likely either nas or profile.

I encountered this bug too, i have to reset sometines my NDS

[ghost]

it only happens on ds games not on wii which strange but bad for ds games but at least wii games don't encounter it

I think it's memory corruption on the DS. On MKDS, the error happens right after the DHCP request but before any actual traffic, but Pokémon Platinum makes it as far as conntest.

This happens on Animal Crossing Wild Word with error code 552201

It does here, too.

Interestingly enough, it did not with the original server iirc.

This even happens on Wiimmfi - it's possible its just some weird DS bug that's finally arisen, since it does seem to error out on bandbroseuds right after the connection test.

Also seem to be getting this on megaman. Starforce dragon/leo/pegasus

It is also possible to get the DS into an inconsistent state if gpcm.gs.nintendowifi.net fails to return a valid LOGGED_IN response (e.g. if the proof-of-login is incorrect). In this case, the user must restart the DS with a soft reboot before Wi-Fi connections can be made. Until the user does so, all attempts to connect will fail at the connection test stage, as if the connection test server did not respond.

This sounds like it could be relevant to this issue. It's from this page.

I found the issue. The server treats the 13 digit console-provided userid as the GameSpy userid, which is supposed to be only 9 digits and generated by the server.

How to fix it?

See my fork here, it's not a great fix but it should work.
