I am planning to play Pokémon Blue & Gold and there is a glitch in pokemon Blue and Red that you can get unlimited shiny dittos so I want them to transfer to my FireRed save file. I downloaded some blue completed saves to test but pkhex is not opening them. Can you tell me if they can open and plz tell a emulator on which I can play gen 1 and 2 games and can trade between them
