The Legend of Zelda: Ocarina of Time
November 21, 1998
The Keaton Mask in the game (that also appears in Majora's Mask along with the creature itself) is based on the Kitsune foxes from Japanese mythology, but is believed by some to also be based on the Pokémon mascot Pikachu, since it's yellow, but most importantly has long ears with a black part on top, much like Pikachu.
The resamblance might be a coincidence, considering that it's basically confined exclusively to its ears, and yet the black parts are shaped differently, and that yellow is a common color used to represent a Kitsune.
Pokémon Stadium 2
December 14, 2000
Pokémon Stadium Gold Silver, known outside Japan as Pokémon Stadium 2, features a Game Boy compatibility that allows to bring "Mystery Gift" items from Pokémon Gold, Silver and Crystal in to the game. These are decorations for the player's character room and include NES, SNES, Virtual Boy and Nintendo 64 consoles. When connecting one of these consoles (except for the Virtual Boy), the TV will show an image from a Nintendo game for that console.
These include The Legend of Zelda, The Legend of Zelda: A Link to the Past, and The Legend of Zelda: Ocarina of Time, when connecting their respective consoles. The first two are gameplay scenes, while for the third one the title screen is shown.
See here for other games that might be shown.
Copyrights for both series are held by Nintendo.
