Hardware missingno icon on a ds game cartridge

[Baby_Sharks]

so wasn't the problem with the cartridge itself? when i insert my SM64DS cartridge into my 3ds it reads it and the game icon appears to be a kind of a missingno and when i boot up the game, the game works without problems, my cart is not pirated or counterfeit so i need some help to fix this right now

If no other carts do it, your cart may have some data corruption on it. It doesn't always present itself in obvious ways.

Do you have CFW?

If not, it's more surprising that a flagrantly bad header is passing the whitelist...
