I realised that wiilink uses “modded” wiiconnect24 channels. And I tried to get the normal wiiconnect24 channels and the wiilink versions so I installed the normal wiiconnect24 channels. Unfortunalely it just replaced them.
When I entered cmoc and evc they were normal, data still there, but the Nintendo Channel didn’t work and its data got probably reseted. Then I installed the wiilink Nintendo Channel and I realised the data got reseted. I didnt think much and installed evc and cmoc but then data from them also got reseted. I found my old Mii Artisan and when I rated the miis, the mii I sent from old Artisan popped and it had different leggins color probably because I own it. (grey I think)
I think only the Support can help here.
Also when installing the wads I got error messages.
