Searching network dumps & videos
As I do not have a WiiU, I'm searching for Mario Kart 8 network dumps. Best is to make a network dump and a video the same time so I can see what happens. If you are able to dump MK8 network data and make a video, please do so, upload the dump and the video and post the download link here. -- Leseratte (talk) 06:50, 29 May 2014 (UTC)
- Leserratte, I think this will help you for sure. [1] --TheMetaPirate (talk) 08:55, 17 August 2014 (UTC)
- Leserratte, do you hang out in some IRC server/channel? I hace become interested in reverse engineering the mk8 network protocol and I am able to record network dumps of me playing mk8. Mgrandi (talk) 20:00, 18 September 2014 (UTC)

urls
In addition to the one URL that the wii u contacts when starting mario kart 8 / connecting online, it seems to contact all of these urls (some of them are just redirects to an amazon AWS instance it seems)
- mii-secure.account.nintendo.net
- 54.225.148.154 mii-secure-proxy-prod-lb-12465627.us-east-1.elb.amazonaws.com
- 69.25.139.186 ias.wup.shop.nintendo.net
- 111.168.21.82 nppl.app.nintendo.net
- 202.32.117.142 nncs1.app.nintendowifi.net
- 107.23.139.110 discovery.olv.nintendo.net
- 192.195.204.136 account.nintendo.net

- 69.25.139.185 ecs.wup.shop.nintendo.net
- api-us.olv.nintendo.net
certificates
In my wireshark capture the wii downloads 6 certificates, 5 of which are signed by the 6th, the nintendo CA root certificate Here is a zip of them (exported from a wiresharp capture), which includes
- account.nintendo.net
- *.app.nintendo.net
- *.olv.nintendo.net
- Nintendo CA - G3 (root certificate)
- Wii U Common Prod 1
- *.wup.shop.nintendo.net
string encoding
It seems that the game uses utf-16-be as its string encoding, as I noticed when racing, at the beginning, my wii u seems to send something like this to every racer i'm facing against: (Mark is my wii character's name )
