Instructions
Download a Pokémon legality checker from your favorite "Pokémon" modding site. Checkers are often included in bundles with "PokeSAV."
Remove the contents of the downloaded folder and place the legality checker on your desktop.
Create a new Pokémon creature in "PokeSAV." Save your new creature as a PKM file to your desktop for easy access.
Click the newly created PKM file and drag it to the legality checker software. The program will automatically open and run a legality test.
Read the results on the checker to determine if your Pokémon is legal. The checker will tell you the Pokémon appears to be hacked or unknown if it is illegal.
