Recently, a flash cart was released for the Nintendo Switch, allowing users to store multiple games on a single cartridge. However, I'd like to know if playing a custom game (perhaps one you coded yourself) or a modded version of an existing game is possible by simply placing the files onto the cartridge. From what I understand, the games are encrypted, so this probably won't work.

Answers to this question should explain if this is possible. If so, those answers should explain how to do so. If not, please explain why not.

If this question is outside the scope of this stack, please refer me to a forum where I could get an answer.

    This doesn't seem a modding question, but instead something against terms of service

  • I'm asking if this will work, not if it's legal.

    I know that. I'm questioning the tag you used, and if the question falls under our scope

  • @PianoCat98 I think it's not illegal, as long as you don't use a pirated game. It's almost certainly against Nintendo's Terms of Service, but that isn't the law.
