I dumped my nand from my Wii U into Dolphin and wanted to use it to play Mario Kart via Wiimmfi. i got the 7.3 patcher and patched the iso, but, when i ran and tried to connect it said i needed a new patcher.(error 23904). i tried several things, different isos, different patch locations, a fresh patcher, riiconnect, none worked. In a discord it said that MK uses a different patcher for wiimmfi but i can't find it anywhere. I already patched Smash Bros and that worked fine, can someone help me?
