Well, I already provided a quote that such a run is possible on Red and Blue as well, but if you insist here is a link:
http://tasvideos.org/1958S.html (First line of the fourth paragraph of "Serious Comments")
Yes, there is not a published run on Red or Blue, but I see no reason not to believe gia since nobody has presented any information to the contrary. In any case, if somebody did make a Blue 0:00 TAS, it would not obsolete the current half-hour TAS. It would obsolete the Yellow 0:00 if it was faster, and otherwise it wouldn't obsolete anything, because that is how the categories work at the moment.
If you don't like those rules, do something about it. But at the moment I am applying those rules to EarthBound, which is a similar case, and under those rules the 9-minute movie which accesses the debug menu should be its own branch.
TL;DR the categories are not Yellow any% and Blue any%, they are RBY any % and RBY "no save corruption". EarthBound should thus also have a "no save corruption" TAS, which would be the one that uses the debug menu.
