For what it's worth, that's also super illegal in the US. The 1970 Magnuson-Moss Warranty Act declares that a manufacturer warranty can not to conditional in any way, shape, or form (for instance, breaking a "warranty void" sticker, or more recently, modifying software. In fact, in the US you'd actually be in the RIGHT to delete the update notification manually, as the DMCA was just ammended to exclude software modification for repair). I do actually seriously recommend talking to a lawyer, regardless of whether you live in the US or EU. Best case, you start a class-action lawsuit that puts Nintendo in its place and allows a bunch of people to reap the benefits. Worst case, Nintendo settles to avoid publicity and you get a fistful of money. The choice would be yours, they're very clearly in the wrongGood luck doing anything about it. Nintendo is breaking European laws for years. For example, if you change the software of something, you lose the software warranty, but you keep the hardware warranty. That means that if you hack a console which then PHYSICALLY breaks, they have to cover it in your warranty. But guess what? Nintendo doesn't give a fuck. You hacked, they say your warranty is voided and that's that. No repair for you. Which is illegal in Europe.
