Yesterday, PokemonAcer and I found out how we can get competitions to work.
(Thanks to @Ciapa for the patcher!).
This is currently a proof-of-concept and not ready to be released to the public yet, because I still need to finish my script which creates the competition file (I don't want to create them with a hex editor all the time)
But when we want to enable competitions on Wiimmfi in the future, we need the competition files to send out 
I have already got most competitions, but not all of them (35 of 46) and not in all languages.
So we need your help:
- If you still see any competition in the Mario Kart Channel (doesn't matter which language or which competition, even if we already have it it can help!) or if the channel says "The competition has ended and the rankings are available", please dump your savegame with the Savegame Manager GX - you'll find the file "wc24dl.vff" inside the extracted savegame
- You can also send me the data.bin file (the complete save game) if you can copy it to SD with Priiloaders "remove copy protection" patch
- If you have an old NAND backup of your Wii somewhere on your SD card or computer, you can extract it with this tool: Download
Then you can open the path /title/00010004/524d43XX/data/ (XX is your region) and extract the file "wc24dl.vff".
- The file "cdb.vff" (which can be found in /title/00000001/00000002/data/cdb.vff) can also be helpful. It does not contain the actual competitions, but the competition letters which contain all the texts for the competitions you have previously received (uploading this file will take a minute, it is quite large)
If you have the wc24dl.vff / cdb.vff / data.bin / RKC file, you can upload it here:
The more competition VFF files from different competitions and languages we can get, the more different competitions and languages for competitions can Wiimmfi support in the future.
