Since its not possible to trade using an emulator youll need to use a workaround to evolve Graveler and other Pokémon that rely on trading to evolve. This page has a guide on how formerly trade-evolved Pokemon will now evolve. If you have a save file from before make sure it gets into the new ROMs folder in the appropriate place.
