If you look at this from that angle, every software can be considered finished and the term becomes pretty meaningless. I can use it and it satisfies my needs, so it is finished. But what really happened here is that the entire system got abandoned - hardware, firmware and games running on top of it - and replaced with a new system and new version of Zelda. They could in principle have maintained the game, ported it to new hardware, improved the graphics, sound and gameplay to modern standards.
