yes you can, all you need to do is buy an X628 Z9 Link
No
nope
No you can't because Blue version is a Game boy game and wasn't designed to be compatible with firered because firered was made 9 years after blue version.
Sadly you can't. You can trade From Yellow to : Red, Blue, Green, Gold, Silver and Crystal. From LeafGreen you can trade to : FireRed, Ruby, Saphire and Emerald.
sorry no you can not
i don't think you can you can only trade from another firered, leafgreen, or a ruby, saphire, or emerald game
no
No. The Mystery Dungeon series is not connected to the main "version" games. In addition, Blue version can only trade with Gold, Silver, Crystal, Red, Green, and Yellow, all of them being Game Boy (Color) games. It can also be connected to the Pokemon Stadium games.
if your talking about it in leafgreen of firered version pokemon, take it to celio, and he will take it and tell you to get a ruby also, then you are able to trade with ruby, sapphire, and emerald games.
trade from blue
Time capsule
You can't because ekans isn't in blue version. You need to trade it from red.
