i think after catching lugia and ho-oh
new safari area after beating the elite 4
by trading
Yes, after you beat the elite four, a new area will open in the safari zone. You will find ponyta in there.
Kanto/Hoenn-migration. Also for Johto but you must migrate from Emerald, after beating the league in Emerald, you go to the Safari Zone and there'll be a new area. In the new area you can find Johto Pokemon including the starters (the starters are EXTREMELY rare to find though.)
You can find the thunder stone in New Mauville
Meteor cave will have a new area opened up once the credits have shown. Look around and you will find steven.
after you beat the Pokemon league a new part of the safari zone will be unlocked and that is where you find stantler
Once you get the National Dex, a new area of the Safari Zone will open up. You can get Teddiursa in there.
In Pokemon Emerald, it's impossible to leave the Hoenn Region. The Kanto, Johto, and Sinnoh Regions are inaccessible in Emerald. Sorry.
The answer to that is the Fight Area. Just like almost any other Pokemon game like Diamond and Pearl.
You Can't. Beat The Elite Four In Pokemon Emerald And There Will Be A New Area In The Safari Zone And There You Found Sunkern. Evolve Sunkern With The Sun Stone And You Have Sunflora!!!
