You can't do that. You can go to Sevii Islands, there are many on 2nd generation pokemon.
By trading for them.
you can't. because the game it self (crystal,silver,gold) is a different size then the ds gba game holder BUT you can trade Pokemon from the johto region to Pokemon firered,leaf green, ruby, emerald, Sapphire THEN you can migrate to dimond/pearl but to do this you need 2 gameboy advance SP games.HOPE THIS HELP :)
No you can't because gold version is for gameboy color and sapphire is for game boy advance or game boy advance SP. But you can catch some Johto Pokemon at the safari zone in emerald after you beat the Pokemon league. you can get the Johto starters if you complete the Hoenn pokedex. Hope I helped.
gold, silver, crystal the much older games the ones with charmander , bulbasuar and squirtle as starters
U can get leaf green on ur computer but it involves downloading visual boy advance a program which can play any gamboy advance game on your computer and using tht to open a gba ROM file(gameboy game) which can be played using arrow keys (u can get leaf green easily) but beware downloading roms is illegal but plenty of people still do it.
You can find the full game download at http://games.softpedia.com/downloadTag/johto
There are two main ways you can get the Johto starters in Emerald. You can get one of the three starters from Professor Birch after you have completed the Hoenn dex. But, if you have Pokémon Colosseum, you can catch the Johto starters' evolved forms: Bayleef, Quilava, and Croconaw. If you purify them, you can trade them to your Emerald version if you have the cable that links the GameCube to the Game Boy Advance. Once in your game, you can breed them to get the starters.
Pokemon leaf green is a Nintendo Game Boy Advance game cartridge. This can be played on the following systems: Nintendo Game Boy Advance Nintendo Game Boy Advance SP Nintendo Game Boy Advance Mini Nintendo DS Nintendo DSlite Nintendo Gamecube Gameboy player
You can't trade Pokemon between GameBoy Color and GameBoy Advance. Sorry.
