Yes you can, if you own a link cable to connect the two gameboys.
No, because Pokemon Yellow is only able to connect to Pokemon Red and Blue. I think Silver and Gold, too. Pokemon HeartGold can only connect to the DS Pokemon games. Besides the migration from Gameboy Advance.
Red, Blue, Yellow, Gold, Silver, and Crystal can trade between themselves. Ruby, Sapphire, Emerald, Firered, and Leafgreen can trade between themselves. Games from list 1 cannot connect with list 2.
Luckily for you bilinguals (I am too :]) yes
Yes it can. Using the Time Capsule in Gold and Silver it's possible to trade between Red, Blue, and Yellow.
In red, you can only catch certain pokemon. In yellow, it's supposed to be a more complete version of red and blue, and in yellow, you encounter Jesse and James from team rocket. In addition, you start off with Pikachu, and later on you get the 3 original starters.
you trade them over from Pokemon red, blue or yellow.
Noctowl doesnt exist in Pokemon yellow, blue, or red
Yes. Orange is between red and yellow.
i would say yellow because you get all three starters.
Pichu does not appear in pokemon red. However, Pikachu can be caught in red, blue and is given as a starter pokemon in pokemon yellow.
no, you catch different Pokemon in yellow, you get ALL 3 starters, and theres no glitch in yellow. :)
