Thats the thing. I recall replacing quite a few files years ago(Maybe IOS files? I was young) and had them reading from the disc channel. I think I did it when I made the wii also read backup discs from the disc channel as well without a modchipMovie player homebrew could read DVD discs from the drive, but the Wii Disc channel hasn't been modified as of yet... And I'm not entirely sure why not. Seems like it would be the easiest way to enable DVD movie playback and disable disc checks.
Unless maybe I am thinking of something else? Just trying to learn ha
