If you want to delete a Pokemon X file, you first need to locate the file. On your computer, open the folder where your game is installed. Inside that folder, you’ll find a subfolder called “Pokemon X.” Inside that subfolder, you’ll find a file called “Pokeball.bin.” (If you’re playing the game on an emulator, there may be a different name for this file.) To delete the file, right-click it and select “Delete.” ..
