Each physical cart has a unique certificate, signed by a private key held by Nintendo. That certificate is verified locally by the console, against a public key in the firmware. Without CFW, you have no way to bypass that signature verification.
In short, the flashcart works by making a full clone of the cart, cert and all. The console doesn't know it's not talking to an original game. That is, until Nintendo's servers notice multiple consoles playing the "same" cartridge at the same time.
If you really are only making and playing backups of your own games then you'd probably be fine, but I don't think anyone really buys these products with that use case in mind.
- graphe 3y agoThank you for your explanation. I thought homebrew would be possible if you have a legit game, have homebrew then just use the cert to play it and make the game console think it's a game. I think if it like a GameShark, you load it with a cert then you switch the game.
