You can't really get Deoxys in Pokemon Ruby and Sapphire the only way to get it into your game is to transfer it from Firered and Leafgreen and Deoxys is located in Birth Island in Firered and Leafgreen.
Pokemon Emerald takes place in the Hoenn region, whilst Pokemon Firered takes place in the Kanto region. Emerald was a third version of Ruby and Sapphire, when Firered and Leafgreen were remakes of the original Red and Blue. The most major difference is what Pokemon appear, the locations, and the trainers.
Unfortunately the only real easy way to catch rayquaza is to use your master ball. if you really want to save it for Latias/Latios (Which you shouldn't because rayquaza is 10x better) is to paralyze him and then use the best ball you have in your inventory, but first you must get him down to low red in hp.
you can use a gameshark code . it enables to learn a Pokemon a move also dragonbreath is a TM try to find it in emerald/firered. or get a rayquaza that has outrage that is better.
It depends on the person. Jirachi is in Hoenn. Which means Emerald,Ruby,Sapphire,Etc. Same with Deoxys. I like Jirachi more personally. But hey, it's you opinion.
I cant tell you all the differences but I do recomend Fire Red version
No emerald is better than Sapphire
emerald no doubt
Emerald..But they are kinda the same
Sapphire is better, but yes, emerald is good.
Pokemon fire red is better.
You mean Staravia? It is not on Firered,leafgreen..... its on Diamond and pearl.... for better answers,Bulbapedia.
HS/SS is better than FR/LG
Emerald.
i recommend scizor because onix exist in both versions and therefore possible for both firered and leafgreen to have steelix. But, only firered possesses scyther and therefore, better for it
a girl is better in sapphire, ruby, and emerald. they have more life and they also nore attack power.
They're exactly the same.
