There is no second time. I don't understand the question.
You cant have the ruby and sapphire at the same time because you have to give the ruby to celio in order to get islands 4-7 which is were you get the sapphire
If you want to trade to ruby or Sapphire you have to fine the ruby and the Sapphire on the seivi islands. If you just want to trade to leafgreen then you can trade at any time.
get the ruby sapphire
Unlike Ruby, Sapphire, and Emerald, FireRed and LeafGreen don't react to time.
After completing the sapphire and ruby quest and beating the elite four for a second time head to two island and talk to the guy who runs the mart, he will sell you timer balls and repeat balls and more.
Sapphire and Ruby were released at the same time, then Emerald was released later.
In Red and Blue: He's in the Mystic Cave, you know, the one cave beside Cerulean City with the guy blocking the entrance the first time you go there. You need Surf though. But in FireRed and LeafGreen, you need an Action Replay to get Mew;Mew is replaced by Mewtwo in the Mystic Cave as described before. Pearl, Diamond, Sapphire, Ruby, and Emerald: Trade Mew to Sapphire, Emerald or Ruby, then over to Pearl or Diamond to get him in the latter games, but for the second gen. ones (Ruby, Sapphire, ect.) Just trade Mew from Blue, Red, FireRed or LeafGreen. My Mew is Lv. 100. :)yes, you can get mew in fire red also mewto.
Same time they do as in Ruby.
Therer isn't one for ruby,only for like Leafgreen an emerald
No the Pokémon Ruby and Pokémon Sapphire version of the Mirage Island is not in Pokémon Omega Ruby and Pokémon Alpha Sapphire however they made their own different variations of the Mirage Island concept but this time by creating more mirage islands that can appear at any time in the water routes or in the sky.
You can trade red, blue, and yellow with each other, and with gold, silver, and crystal once you have the ability to use the time machine trader (trades older pokemon with older moves/items). You can trade these games to ruby/sapphire/emerald with no problem up to my knowledge. FireRed and LeafGreen can only trade to each other, and ruby/sapphire ONCE the Elite four are beaten and you retrieve the gems for Celio on the Sevii Islands. You can only trade one way from ruby/sapphire/emerald to Diamond/Pearl. Hope this helps!
you can't. to get an espeon or umbreon, you need to evolve an eevee at certain time of day. leafgreen/firered don't have clocks. you have to trade the eevee to ruby/sapphire, max out friendship and level up in the pm for espeon, am for umbreon.
