You can't
First you start a new game and then just save over your old saved game.
No.Once you saved another place on Pokemon Emerald , you cant go back to where you saved last time
My file was saved over by accident and i need to get it back can I? On the emerald Pokemon game boy advanced. Please help? soon
no you can't. if you saved in ur new data, THERE IS NO WAY.
On the intro screen (where Giratina is), you must press B + Select + Up together. You will then be asked if you want to delete your old saved data. If you want to start a new game and be able to save it, you have to delete your old data first. Otherwise, you will be unable to save.
Sadly... no.
the old chateu is only in Pokemon diamond pearl and platinum versions
Old sea chart
you get a wynaut from the old lady
Im afraid if it has ruined your game, you will have to delete your old saved data and start a new game. Sorry
get it from an old man in shoal cave
There are no more Pokemon Nintendo events for Pokemon emerald unfortunatelt because the game is five years old Sorry
