if it is saying "save file corrupted" then your internal battery is dead. this battery powers the chip that saves data. to fix this just Google "how to replace a GBC internal battery". This same thing happened to me with my Pokemon crystal but i fixed it in a half an hour for less than $10.
It can't be done.do not duplicate your Pokemon your game boy save will be delete
you cant
Did you save the game yet if yes start a new game.
No, Pokemon Omega Ruby and Alpha Sapphire can only have one save data per game.
well you can download Pokemon sapphire so you can save .
Just hit New Game and save it. It'll erase your other game' so only do it if you really want to.
you cant it woul overight the last save data
because Pokemon chaos black is a fake Pokemon game packed with errors
if you saved after that you cant get him, but if you didn't just turn it off and start from your last save. Hope this helps!
You go to the menu hit save and you cant leave the site you can shrink it
yes you get them by haveing a game shark and you save wright at the beginnig and you can get deoxis bou don't get a Pokemon you get later in the game you can only do this once for file
=To duplicate first you must put the Pokemon you wish to copy in a box all a lone then save and turn of the game for a whole day=
