So I ran Mario Kart Wii as Wii VC on my Wii U a few months ago, which likely caused the SYSCONF overwrite (like it's mentioned on the Priiloader FAQ).
Side note: I also used the vWii Transfer Tool.
As the result I noticed, that my vWii is semi-bricked, according to various crashes in relationship to SYSCONF and infant Any Title Deleter straight up tells me.
Here are some examples: any channel that I guess uses save data as well (such as the Nintendo Channel, regardless if it’s the WiiLink one, or Wii Shop Channel) just freeze on startup.
I tried to fixing it:
• vWii Decaffeinator (worked just fine until the update failed at the end with an Error Code)
• modifying it manually with ChatGPT and the Wii U‘s FTP Client
Another solution would be to extract the SYSCONF from an Backup what I done and may contains the vWii before I modded my Wii U but I don’t know how it is affected by the transfer or how I open the backup in the first place.
Does anyone know how to fix this?
