Did Nintendo release boxed Nintendo 64- or Gamecube-brand svideo cables?

We already know that US SNES, and Super Famicom, both exist. (Not sure about PAL) So those are covered. Really no need to discuss there.

But what for N64 or GC? I've never seen any sign Nintendo issued svideo cables for the two systems in a box. Not like how even the now expensive GC component cable did reach Japan that way.

 

I've never come across any official N64 or GC S-Video cables, only 3rd party versions.

 

Gamecube S-Video yes

They also did mono composite cables as well as component and D-Sub

The Nintendo 64 however, did not have custom cables as Nintendo just told people that they could use Super Famicom cables and you can see this here as the cables have the SFC codes.

I have a monster branded S-Video for the Game Cube I use them for audio

 

D-sub? Do you mean D-terminal? I don't see why they'd make a cable with a D-sub connector, considering the GC couldn't output VGA.

 

I doubt there's much of an audience who'd care about the mono composite cable enough to hunt for CIB on it either. Most often they were packed with AV Famicom.
