Is Dolphin banned for Wiimmfi servers??

[mbc07]

Console ID is stored in Wii/shared2/DWC_AUTHDATA if I'm not wrong. The console ID is based on MAC address and it's created only one time. It's automatically reset if you use "Format Wii Memory" option or if you erase NAND dump folder in Dolphin AND start a new save file using 4.0-1019 or newer... Some games also store the console ID within it's own save file, so, in these cases just erasing NAND dump in Dolphin isn't sufficient, you need a new save file.
