If it has the same bugs on the debug console as on a retail one, why only have it boot on those?

Because the debug console has more memory to allow it to use the flipnote making mode, which retail consoles would likely never run.
Also, because there's no point in having Flipnote run for a majority of users (with retail consoles) if they can't make any flipnotes.
