You can't beat the champion just with sceptile unless it was lvl 100 and it knew good moves plus it was the first time you vs them.

Yes once you beat the champion the game ends but you can still play the game.

After you beat the champion in Pokemon Emerald, you can ride the ferry. Unlike in the Ruby and Sapphire versions, in Emerald you can travel to something called the "Battle Frontier." I don't want to give any spoilers for those who haven't finished the game, so all I will say is that it is worth the wait! Also, you can continue catching the legendary Pokemon and other Pokemon.
because you beat the game. but you can still train. and you can get more legendaries.
You have to beat all gym leaders and the Elite 4 and Champion.
go catch rayquaza and poof its a breeze
Usually they have it at Gamestop. Do not get it in a online store! They could have fake Pokemon games like mine which always deletes after you beat the champion Wallace. Pokemon Emerald costs up to $40 because it a bit rare now.
