My friend has an unmodded wii and is trying to use ctgp to connect mario kart wii to wiimmfi but keeps receiving error code 20100. The console is connected to wifi and it says connection successful in the wii settings. it also is not working with vanilla mkw and wiimmfi dns.
One person that...
although i ended up accidentally changing my nand with no way of going back bc i didn't know you needed a gamecube controller to restore it (i have a wii minus/1.1, which doesn't have gamecube controller support)
and if i find the sd card i have my NAND backed up on, i can not only restore the NAND if i solder the right part in, but i can also put my NAND on dolphin, then i can play dolphin online, like PMEX Remix or MKWii Riibalanced
