Does anyone know if the downloaded update data is shareable? I assume that it's not, that it's encrypted using the device id. Just curious. If it isn't, couldn't folks simply share the update data that gets stored for the given title in the Nintendo directory on the SD?
For now I am using the method from the OP and everything is fine. Understood per many folks here that I should expect to be banned, but my take is the following-- I might as well install updates for all of my favorite games while I can, since if they do in fact start stopping users from updating titles after a ban, and do start banning folks for doing so it will take some time before the scene develops alternative solutions.
Worth mentioning also that this is separate Switch I purchased just for this purpose, so I'm fine with a ban if it happens.
