Overwrite the save file on your physical Emerald cartridge with the .sav file on your SD card. What to Look For Before Downloading
Obtaining all Pokémon in Pokémon Emerald is a challenging task that requires dedication and perseverance. There are several ways to obtain all Pokémon in the game, including:
: All 8 gym badges collected and the Elite Four defeated. Technical Requirements
Simply drag and drop the .sav file onto your micro SD card alongside the ROM.
Ensure your save file matches your ROM's regional code. A North American (USA) save file will usually fail to load on a European (EUR) or Japanese (JPN) ROM.
: Having a ready-made roster to tackle the post-game facilities.
: This is the biggest hurdle. If your save corrupts, it is likely because the emulator is trying to load a 64kb save into a 128kb environment. Switching to mGBA or using a "512kb Flash Memory Patch" can resolve these issues.
