If you’re looking to delete your Pokemon Sun data, there are a few different ways to go about it. The first option is to use the Nintendo 3DS system’s built-in erase function. This will erase all of your data, including any saved games and progress. If you don’t want to use the system’s erase function, you can also delete your data manually by deleting the Pokemon Sun game files from your SD card. Finally, if you’d rather not delete your data at all, you can always transfer it over to a new copy of the game. ..
