Create custom GP / tournaments

[Dr-Wily]

Hello,

Is there a way to create a custom GP or tournament with specific rules ? I think about the Mario Kart channel where we can join some contest. Why ?

Because if I want create a contest on 1 cup only, I must create a room and register all friends codes... pretty tricky...

There is another solution ?

This is very game-specific, not exactly a priority. I assume in Mario Kart Wii's case this goes over the Sake server in some way.

The difficulty of doing stuff like this is we don't have the necessary packet captures to figure out how these events were originally done on the server. Wiimm might but he isn't exactly sharing anything with us.

You'll need to find an experienced Wii hacker willing to volunteer their time to make this work.

[Dr-Wily]

OK. I can make packet capture, but in which way, have you some specific tools for that ? Or a simple wireshark is enough ?

[BadBreath69]

no, you need MKW-AN: http://mkw-ana.wiimm.de/

You do neither need mkw-ana nor wireshark, but any packet dumps from before May 20, 2014 containing data about a Wii actually downloading the newest competition via WC24.

I did not find any of this dumps in the internet, so you probably need to decompile the game and understand Assembler code to find out.

Also, you need to patch the WC24 engine (I don't know how) to remove the certificate validation.

So, I highly doubt that is possible in the near future.

@mm201 just to let you know, SAKE was used for GHOSTS and other files, not for competitions which were downloaded via WC24 daily.

I belive i saw ghost dumps somewhere just before the 20th of may , im breaking my head over finding it again.

We have beta ghosts and rankings at Wiimmfi...

[Dr-Wily]

Have you seen this ?

[ghost]

Yes, we all have; it has been highly publicised.

[Dr-Wily]

There is a way to implement it on altwfc ?

[ghost]

It's unlikely to occur.

[Dr-Wily]

Why ? There is missing some details...

[ghost]

Big bump: because Wiimmfi isn't a public opensource thing.
You can find the DISTMAP.BIN files on Wiimmfi themself but GL getting someone to reverse engineer it.

Similar to my comment in #157 , is it worth leaving this issue open when AltWFC's main instance no longer supports MKW?
RKCs have already been reverse engineered and the format is on Tockdom along with an existing editor.

[mm201]

It would still be cool to RE and document the server portions for posterity.

[InternalLoss]

Well, while I haven't put the competition info there, I was working on documenting it at the Tockdom wiki
