Sapphire and Ruby came out before firered and leafgreen but they are compatible with them.
Ruby and sapphire both were made in 2003, firered and leafgreen both were made 2004 and emerald was made in 2005. So to answer your question yes ruby and sapphire were made before firered and leafgreen though firered and leafgreen are based on the original red and blue version so if you want to get technical firered and leafgreen where made first. But in reality ruby and sapphire were made first.
You can get Charmander in Pokemon Sapphire by obtaining it in Pokemon FireRed or LeafGreen and trading it to Sapphire. To have Charmander registered in the Sapphire PokeDex, you must defeat the Elite Four. You may have the Charmander before that, but it won't register in the PokeDex.
It is located in Mt. Ember on Island One after you beat the Pokemon league. The cave that the rockets were blocking before is open for exploration after talking to Celio about the ruby and sapphire. After you get both, you can trade Pokemon Firered and Leafgreen to Ruby,Sapphire,Emerald,Colossuem and XD.
Sheildon is a sinnoh Pokemon. Sinnoh came out after Hoenn, so, sorry... you can't catch it in ruby (or Red, Blue, Green, Silver, Gold, Sapphire, Emerald, FireRed, or LeafGreen, Or any fake Pokemon games that came out before 2007)
You can trade from Sapphire anytime. However if you are trading to or from Leaf Green, you have to have beaten the Elite Four first, before you can trade with Ruby, Sapphire, or Emerald.
actually, you can only clone in leafgreen and firered. trade the Pokemon you want to be cloned with one that you don't care about. next at the end of the trade, right before it saves, cut it off. (i mean right before). but only cut off the one that you want to clone. tested and works.
Ruby/Sapphire/Leaf Green/Fire Red/and i think Emerald. if not, trade from emerald to Ruby/Sapphire, and from ruby/sapphire to leaf green. You need to have the Sapphire and Ruby before you trade. you get these after the elite four.
I don't have a Mudkip. But I herd u liek 'em.
you dont you use cut on the door to the inside of the door, ive done it before
It is in cereulan city. You can only go there before you beat the elite 4 and bring the ruby and sapphire to celio. You can catch mewtwo there.
yes
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.
