Restoring discs with NKit

Wii discs are often stored in .wbfs format which saves space by removing junk data. NKit accurately restores that junk, converting the wbfs file back to a Redump iso. NKit also introduces a .nkit.iso format which is ideal for GameCube gaming on consoles, plus it's fully restorable to iso using NKit.

To restore the disc NKit needs a copy of the update partition (for most games) but happily there aren't too many of them. You can grab a copy of NKit with all the partitions you'll need below.
