Extracting disc contents then converting/reassembling to ISO won't play on a real Wii

[mbc07]

Why not use WIT to rebuild the ISO? AFAICT the folder structure generated by Dolphin's "Extract Entire Disc" command is the same as WIT, so it should be possible to use it to rebuild a fake signed ISO at the last step (e.g. Extract disc with Dolphin => Modify the game files => Build a new ISO with WIT)...
