I've never played Zelda 1 for more than a few minutes, Zelda 3 was my first, so I don't know what you're talking about.
However, Danny.B is well accustomed to the game, I'll ask him to check it out.
However I will say one thing: it's very un-Nintendo to rework modern (read: original) features into a VC game, hence no rumble in StarFox 64 etc...
Actually, that's really only been the case with N64 games... And I think they just chose to exclude rumble in order to prevent the GameCube controller gaining favorability over the Classic Controller. Then, not allowing savability via emulation of the Control Pak was just their way of trying to look consistent.
If you look at VC games from other systems, special features
are consistently supported. Games that originally supported 4 players via an adapter,
will support 4 players. Excitebike's save feature never worked on an original NES since the Famicom Data Recorder was never released-- but the feature
did work when the game reappeared as an unlockable in Excitebike 64 and Animal Crossing, as well as its GBA release as part of the NES Classics Series. And let's not forget the multiplayer support already promised for these games for a future update.
With all that in mind, it's really more 'un-Nintendo'
not to support an original feature for a non-N64 VC title.
