Converting games with NKit
Wii games are often stored in .wbfs format which saves space by removing junk data. NKit accurately restores that junk so you can finally verify .wbfs games in Redump. The new .nkit.iso format makes games even smaller and works with both GameCube and Wii games. NKit games are also supported by Dolphin and GameCube loaders.
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.
