someone has sold 4 copies of tears of the kingdom on a website called mercari for $300 each. he has a 5* rating with over 300 reviews since 2020. mostly sells shoes.
this cartridge isn't like one we have seen yet, the others being definite fakes.
i don't know how i've never heard of this, but if you type ENGAGE RIDLEY MOTHER FUCKER on the metroid password screen, it completely fucks up the game and can even hard crash a 3DS.
