First post, hope this is the right place for this sort of thing.

If you're like me, your wife bought you Guitar Hero III many years ago and now you're old and you want to relive that fun. And oh yeah since then your wii optical drive has failed so you can't even use the disk you have. And modern macbooks don't have an optical drive so you're left to......ummm.......find other means of acquiring that iso. Seems like this is a common problem, but it also seems that the solutions/workarounds are all Windows-centric.

So I set out to make this work on a Mac. I'm sure somebody else has done this before, so apologies if this is well-trodden territory. Much of the problem space is probably understood as well. So forgive me if I explain that which is already well known. Claude insisted that it couldn't be done, but I was not going to be denied this day.

In essence, the nkit file is the iso with the system update partition removed in order to save space. There is a very real chance that you don't have your update partition data, especially if you're in a position of discovering that your drive no longer works. But no worry, there is a way around it (possibly the same mechanic as how the Windows solutions make it work?). We're going to use NKit to inject some filler into that partition. NKit will puke because the resulting file won't validate. No worries, we can use an undocumented debug mode to force it to generate a "bad" file. Then we can use wit to strip out that partition while converting to .wbfs

And just like that, you're able to play Guitar Hero III on your Wii again.

It's sorta hidden in the NKitv1 repo, in the Converter.cs file, starting around line 420:

Code:
    //FAIL
    if (results.ValidateReadResult == VerifyResult.VerifyFailed || results.VerifyOutputResult == VerifyResult.VerifyFailed)
    {
        LogBlank();
        Log(string.Format("Verification Failed Crc:{0} - Failed Test Crc:{1}", results.OutputCrc.ToString("X8"), results.ValidationCrc.ToString("X8")));

        if (lastTmp != null) //only null when verify only
        {
            Log("Deleting Output" + (Settings.OutputLevel != 3 ? "" : " (Skipped as OutputLevel is 3:Debug)"));
            results.OutputFileName = null;
            if (Settings.OutputLevel != 3)
                File.Delete(lastTmp);

             LogBlank();
        }
    }
