What online switch game is worth playing? I'm sure the mig will be decrypted, and they will just fake the signature for the homebrew games. I think that's how some of the older homebrew worked. The scene is pretty dead since smartphones exist though. I agree he should just get an old one but aside from maybe not liking the mig guys I don't see a problem with the product. The amount of blood from mining in Africa for my minerals probably isn't too moral either.

  Can you explain how it works? I read a bit here. https://wololo.net/2024/01/10/it-appears-team-xecuter-are-back-with-the-mig-switch-flashcart/ https://wololo.net/2024/01/10/it-appears-team-xecuter-are-ba... it seems you can use different game certs to make it launch.

    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.

      Thank 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.

        Everything is signed, there's a chain of trust.

    The unique certificate is mainly used to verify that a cart is authorized to be played online, the game files themselves are signed in their entirety and a console not running CFW will not accept any modified files.
