Original memory cards support this, while no bootleg card seems to do so (tested with 7 of them).
If the card passes the test it could be a good sign that you have an og card.
IMPORTANT NOTE:
To avoid issues, please make sure to unplug and re-plug the cards before running the test ELF.
It seems like when cards are authenticated once with retail keys they can't go back to developer keys until they're disconnected.
