I was experimenting with the Homebrew channel in Dolphin Emulator and decided to copy it to the virtual SD card and extract the file from my virtual SD card to my actual vWii SD card. What I found when clicked on the SD card button was a channel labeled with 3 question marks. Upon trying to launch it a message pops up saying, "This channel cannot be launched on this Wii console." It also doesn't let you copy or move the file to the system. If anyone might know any more information or even a way to bypass this please let me know.
